'''Shards''' are a somewhat rare resource added by the [[Anomaly DLC]] with a number of varied and powerful uses.

== Acquisition ==
Shards can be acquired in the following ways:
# [[Quests#Distress_signal|Distress signals]] are guaranteed to spawn a flesh sack with a shard in it.
# Destroying certain [[entities]]:
## [[Metalhorror]]s have a 50% chance to drop a shard when killed.
## [[Nociosphere]]s, if killed, will drop 2 shards.
## [[Revenant spine]]s, when smashed, will drop 2 shards.
## [[Dreadmeld|The Dreadmeld]], when killed, will drop 3 shards.
## [[Fleshmass nucleus|The fleshmass nucleus]], when killed, will drop 2 shards.
## [[Unnatural corpse]]s, when destroyed, will drop a shard.
## [[Obelisk]]s allowed to reach max activity level or destroyed by damage will drop a single shard after exploding.
# Found inside crates in the [[warped obelisk]]'s [[labyrinth]]
# An [[entity]] raid, including [[horax cult]] raids, have a chance scaling with raid points to give a random entity a hidden hediff that will cause it to drop a shard.

== Usage ==
Shards are used in the following crafting recipes:
{{Ingredient List}}

Two shards are also required to deactivate the [[corrupted obelisk]] and [[twisted obelisk]], while one is required to deactivate the [[golden cube]].

== Analysis ==
{{Stub|section=1|reason=Prioritize best uses of the shard in early, mid and late game. Describe easiest forms of acquisition (metal horror farm?). Recommendations for keeping at least X many on standby for dealing with threats that require them (cube, obelisks)}}

Shards are versatile and required for many aspects of Anomaly. While they are rare in the early game, they become more and more abundant: the colony will have more ways to farm shards and entity raids are more likely to drop shards. In addition, many of the buildings that require shards - such as [[shard beacon]]s and [[serum lab]]s - are capped or only one building is necessary.

=== Usage ===
It is wise to keep one or two shards on hand in reserve, in case of anomaly threats that require them to deactivate, with the next few shards used to produce [[ghoul]]s. A few ghouls as melee units and melee blockers will make combat challenges easier, including fighting [[dreadmeld]]s, one of the main sources of additional shards.

=== Farming methods ===
Beyond the natural amount of shards from distress signal quests and entity events, the following methods can be used to gain shards:
* [[Void provocation]]: Causes another entity event, which may provide a source of shards. A shard is not guaranteed, but void provocation is available in the early game.
* [[Provoke pit gate]]: Guaranteed to provide 3 shards if the [[dreadmeld]] can be defeated.
* [[Metalhorror]] farming: This involves intentionally containing and spreading a metalhorror infection, allowing metalhorrors to be farmed for their shards.

In addition, initiating the [[monolith endgame]] will cause [[metalhorror]]s to spawn, resulting in a lot of shards depending on [[raid points]].

Genes

2026-07-19T03:25:59Z

MortalSmurph: /* Miscellaneous */ This line seemingly has no meaning / effect. Bionic/Archotech eyes don't have any effect on Darkness nor the Dark Vision gene

{{Biotech}}
{{Recode|reason=Thought templates}}
{{See also|altphrase=This page is a list of genes. For a full explanation of the gene system see|Genetics}}
'''Genes''' are a system for modifying [[human]] pawns, added by the [[Biotech DLC]]. They can be obtained from character creation or implanted via [[xenogerm]]s.

== Mechanics ==
Genetics are limited by metabolic efficiency, denoted by the [[File:Metabolism.png|20px|Metabolism]] symbol. This affects pawns' [[hunger rate]]. Harmful genes improve metabolic efficiency, lowering hungry rate, and thus consuming less food overall. Helpful genes lower metabolic efficiency, getting hungry faster. A baseline human has a metabolic efficiency of 0 (100% hunger rate), and genes can bring it as low as -5 (225% hunger rate) or up to 5 (50% hunger rate). The game will not allow the creation of xenogerms with a metabolic efficiency lower than -5.

Note that genes with over [[File:Metabolism.png|20px|Metabolism]] 5 cannot be extracted by themselves, and must be extracted in a pack with another gene that lowers metabolism cost.

Complexity, denoted by the [[File:Complexity.png|20px|Complexity]] symbol, affects how many [[gene processor]]s you need to create a [[xenogerm]] from a set of genes. A [[gene assembler]] can create xenogerms with a maximum complexity of 6, plus 2 for every attached gene processor. Complexity also determines the base time it takes to create the xenogerm, ranging from 4 hours at ≤3 complexity, to 23 hours at ≥20 complexity (which is then scaled by the [[research speed]] of whoever operates the gene assembler).

== Gene expression ==
When looking at a pawn's gene tab, each gene can be considered to be in one of three categories:
* [[File:GeneBackground Endogene.png|32px]] Germline Genes
* [[File:GeneBackground_Xenogene.png|32px]] Xenogenes
* [[File:GeneBackground ArchiteGene.png|32px]] Archite genes

Germline genes are freely distributed through and only through [[reproduction]]. Xenogenes are genes that have been [[Operation|surgically implanted]] through a xenogerm, and can override germline genes that are identical to or conflict with the xenogene; a [[Dirtmole]] that was converted into a [[Sanguophage]] will have half of their genes overwritten by the Sanguophage xenotype. Xenogerms cannot be passed through reproduction.

Note that germline and xenogenes are determined by the way they are obtained, not by the effects of the gene itself. For example, there is only one [[fire resistant]] gene coded into the game - "germline fire resistant" and "xenogene fire resistant" are the same gene obtained in different ways. Trying to have both would simply disable the redundant germline version.

Archite genes are non-inheritable (even if they are forced into the germline of a [[Xenotypes#Customization|custom xenotype]]) and xenogerms containing them must be supplied with the requested number of [[archite capsules]] before being assembled. Archite genes cannot extracted through the [[gene extractor]], but can be implanted using the [[gene implanter]] ability.

== Work Required ==
The work required to create a xenogerm is determined by its [[File:Complexity.png|20px|Complexity]]. First, a base value is obtained from the post-process curve with the points:
:{| class="wikitable"
|-
! colspan=2 |Xenogerm work
|-
|
* (0, 3)
* (4, 5)
* (8, 8)
* (12, 12)
* (16, 17)
* (20, 23)
| {{Graph:Chart|width=400|height=100|type=line|x=0,4,8,12,16,20|y=3,5,8,12,17,23|xAxisTitle=Gene Complexity}}
|}
This value is then multiplied by 2500 to obtain the final number.
:{| class="wikitable"
|-
! colspan=2 |Xenogerm work
|-
|
* (0, 7500)
* (4, 12500)
* (8, 20000)
* (12, 30000)
* (16, 42500)
* (20, 57500)
| {{Graph:Chart|width=400|height=100|type=line|x=0,4,8,12,16,20|y=7500,12500,20000,30000,42500,57500|xAxisTitle=Gene Complexity}}
|}
The actual time required is inversely proportional with the [[research speed]] of whoever operates the gene assembler. At 100% research speed, it takes between {{ticks|7500}} (for 0 complexity) to {{ticks|57500}} (for complexity 20 and above).

* If a pawn would've died, but the brain, head, or neck is not directly destroyed, they enter into either a regenerative coma or involuntary deathrest.
** Pawns without the Deathrest gene enter a regenerative coma. After all fatal conditions are removed, the regenerative coma lasts for 7 more days. [[Hemogen]] is unaffected.

=== Melanin ===

These natural skin colors are '''not available in the xenotype editor and cannot be extracted'''. Every person gets one of these as a germline gene unless they already have a skin-color germline gene (e.g. [[File:Dirtmole.png|20px|link=Dirtmoles]][[Dirtmoles]] have light gray skin instead of these).

These genes are defined in Core, not Biotech. They are all named "Skin color" in-game.

=== Skin ===
These exotic (non-natural) skin colors do not appear on anyone without the gene. Like body type genes and hair genes, a person can have more than one skin color gene (e.g. [[File:Impid.png|20px|link=Impids]][[Impids]] have three), and one will be chosen.

All of these genes have a "random brightness factor" of 0.18 unless otherwise specified.

<onlyinclude>
{{imagemargin|[[File:prisoner_preview.png|right]]|18px}}'''Prisoners''' are [[people]] who have been taken captive. This usually includes [[raiders]], but colonists can be imprisoned too.{{TOCright}}</onlyinclude>

== Summary ==
Prisoners are ordinary pawns under restraint. They have no [[Recreation]] needs, but all other needs and most [[mood]]lets apply to them. This includes a need for [[food]] and the chance for [[mental break]]s. They are confined to their cell and will not do work. Prisoners retain their faction allegiance; imprisoned colonists who are released will immediately rejoin the colony, while other prisoners will try and leave the map. Prisoner restraints reduce their [[move speed]] by 65%.

Prisoners cannot open doors if not undergoing a [[#Prison Break|prison break]]. While inside your colony, they will try to leave if there is an opening, such as a hole in the wall or a held open door, including if it is held open because of an item inside. A prisoner that can move will wear the most comfortable{{Check Tag|Verify/Detail}} clothing placed in their cell. They eat the food with the best mood buff that they can reach, ignoring food restrictions. Mobile prisoners can use a [[nutrient paste dispenser]] that faces into their prison. Otherwise, wardens will bring any food allowed by their [[Food restriction|food restrictions]]. A prisoner's medical settings, as well as defaults for all prisoners, can be adjusted in their Health tab.

Colonists assigned to Warden can interact with a prisoner in multiple different ways, including delivering food and recruitment. Colonists assigned to either Warden or Doctoring can feed a prisoner in medical rest. See [[#Interaction]] for more details.

=== Unwaveringly loyal ===
Unwaveringly loyal prisoners are unable to be recruited to your colony, and do not have resistance to lower. They are otherwise the same as regular prisoners, including the ability to become a [[slave]].{{IdeologyIcon}} Unwaveringly loyal pawns without a faction will be described as "not recruitable".

Unwaveringly loyal prisoners can be recruited after undergoing the [[Brainwipe]] psychic ritual.{{AnomalyIcon}} Additionally, if an unwaveringly loyal pawn joins your colony through any means, they will lose their unwavering loyalty. Thus, unwaveringly loyal pawns from a temporary faction (such as the [[Factions#Refugees|refugee faction]] {{RoyaltyIcon}}) or [[Factions#Factionless_humans|no faction]] can be recruited by [[Slavery|enslaving]] {{IdeologyIcon}} them, which makes them a member of the player's faction, and then emancipating them, which makes them a normal member of the player's colony. Friendly [[shamblers]] {{AnomalyIcon}} also automatically join the player's faction, which will remove the unwavering loyalty of a prisoner, though they will have to brought back to life with a [[resurrector mech serum]] to be recruited as a normal colonist.

Unwavering loyalty can be disabled in the [[storyteller settings]]. Note that the enabling unwaveringly loyal pawns decreases the percentage of raiders that are automatically killed on [[down]]ing to almost exactly make up for the percentage of pawns that are now unrecruitable - this means that the number of recruitable prisoners remains constant with either option, but the total number of prisoners increases with unwaveringly loyal enabled. This is pure benefit if the player only intends to recruit from the pool of randomly downed raiders, however if the player was willing to specifically target good pawns for safe-downing and recruitment, such as through [[blood loss|bleed]] kiting or [[psychic shock lance]], then some portion of those previously recruitable pawns will instead be loyal and thus unavailable.

=== Caravans ===
Prisoners can be loaded into a [[caravan]]. If they can walk, they can carry 35 kg worth of items, like your colonists. When inside a caravan, the prisoner will never try and escape unless its part of a [[mental break]].

If the caravan enters a loaded map (such as an ambush), the prisoner will wander around idly, and may walk into the crossfire. Enemies will also target prisoners if their factions are enemies.

== Capturing prisoners ==
In order to capture any prisoner, you need a valid prison, which is enclosed and has an open [[bed]] or [[sleeping spot]] (See [[#Prisons]] below).

The gameplay steps required to capture a pawn depends on their state:
* [[Downed]] pawns can be captured with 100% success, without drafting a pawn. Select a colonist, and right click the future prisoner.
** [[Raider]]s, [[berserk]] pawns, and former prisoners in a [[prison break]] are unable to be captured directly. They must first be [[downed]].
** NOTE: Raiders in particular have a [[AI Storytellers#Enemy death on downed|chance to die]] whenever they are downed from [[pain]] - such as from being injured. This does not apply if the pawn is downed from other causes; some ways to get around this include:
*** [[Psychic shock lance]], although there is a risk of burning the brain
*** [[Blood loss]]
*** [[Tox gas]],{{BiotechIcon}} although not all xenotypes are affected, and [[Toxic buildup]] also has risks
* To ''arrest'' a colonist, guest, ally, or [[slave]],{{IdeologyIcon}} you need to [[draft]] a colonist and select the target to capture. The colonist will then walk up to the target and attempt a capture. The chance of success depends on their [[Arrest Success Chance]], and will be displayed on the prompt. Arrest success chance largely depends on [[Social skill]], but is negatively affected by [[Manipulation]] penalties. If the arrest fails, the target will go [[berserk]]. Pawns with the [[dead calm]] gene{{BiotechIcon}} always have a 100% success chance, regardless of arrester stats, and thus will never go berserk when arrested.
** Colonists can be captured even during a [[mental break]], except for [[berserk]]. This immediately ends most mental breaks, without catharsis. When released, colonists will get the {{--|6}} ''Was imprisoned'' [[mood]]let for 12 days. This mood penalty will not occur if the colonist is instead re-recruited. Arrests will not end the [[Mental break#Run wild|run wild]] or [[mental break#Catatonic breakdown|catatonic breakdown]] mental breaks.

If you attempt to capture a pawn from a neutral or allied [[faction]], the faction will immediately turn hostile. This includes [[transport pod]] crashes, if they happen to be part of an existing faction.

If you need to capture a pawn, then [[sleeping spot]]s can be used to instantly create a prison and bed space anywhere indoors. You can also turn a colonist bedroom into a prison.

=== Reasons to imprison ===
* To recruit raiders, guests, or transport pod crashes into a colony.
* To use raiders for their [[human resources]].
* To end most [[mental break]]s. Colonists can immediately be released afterwards.
* To keep a colonist restrained in order to overcome [[drug]] withdrawal.
* To convert a colonist or [[slave]] to a desired [[ideoligion]].{{IdeologyIcon}}
* To act as sources of [[Bloodfeeder|bloodfeeding]] or [[hemogen pack]]s.{{BiotechIcon}}
* To sell the prisoner.
* For raiders, to release them for a goodwill gain of the enemy faction (faction must not be permanently hostile and the released prisoner must exit the map healthy).

== Prisons ==
[[File:Thank you Megasloth for letting my prisoners run.png|thumb|right|350px|Megasloth getting sheared at the exit of a prison door, holding it open for a prisoner to escape.]]
Prisons are required to hold prisoners.
=== Creation ===
A prison must be designated in a fully enclosed [[room]], closed off with [[wall]]s and other impassable objects like [[door]]s, [[cooler]]s and [[nutrient paste dispenser]]s. Prisoners cannot be captured unless the prison is enclosed, and mobile prisoners will walk out of the map if an opening exists.

In order to actually form a prison, at least 1 [[bed]] or [[sleeping spot]] must be placed. Selecting the bed allows you to set "For Prisoners". Colonists and [[slaves]]{{IdeologyIcon}} may not share the same room as a prisoner; when 1 bed is set to prisoners, all beds will be converted to prison beds. The beds will turn orange to signify this, and the whole room gains an orange outline when selected. In order to actually capture a prisoner, there must be an open sleeping area for them to stay.

=== General ===
A prison is called a ''prison cell'' if there is 1 bed available, or a ''prison barracks'' if there are multiple beds. A prison is otherwise treated as a bed room or barracks, including [[mood]] impacts for its Impressiveness.

Prisoners can only use items that are in their cell. Food, beds, and [[nutrient paste dispenser]]s placed inside a prison are reserved for prisoner use. While a colonist can be ordered to eat food placed in a prison cell, they will not automatically do so. Colonists on the food binge [[mental break]], as well as [[animal]]s, will ignore a prison for this purpose.

Unless you want your prisoners to die, make sure that it is hospitable. Regulate the [[temperature]], or give prisoners sufficiently insulating [[clothing]], such as [[tribalwear]]. Make sure that food gets to a prisoner (either via a storage zone, warden delivery, or [[nutrient paste dispenser]]). Otherwise, see [[#Mood regulation]] for how to make your prison better for the inmates... or worse.

== Interaction ==

=== Resistance ===
{{see also|#Recruitment{{!}}Recruitment}}
Prisoners start with '''resistance''', or unwillingness to join the colony. This must be lowered to 0 for recruitment attempts to begin. Unwaveringly loyal prisoners do not have a resistance stat, and can't be recruited.

Under the ''Recruit'' or ''Reduce Resistance'' orders, wardens will attempt to lower the resistance. How much is reduced depends on a prisoner's [[mood]], the warden's [[Negotiation Ability]], and the prisoner's [[opinion]] of the warden. Wardens with more [[Social skill]] have a greater Negotiation Ability. There is a delay between each conversation.

Once resistance hits 0, wardens will try to convince the prisoner to join the colony, with a chance to succeed, depending on each prisoner's recruitment difficulty percentage, their current mood, faction, how many colonists you currently have, as well as your [[storyteller]]. If the prisoner is assigned to ''Reduce Resistance'', then wardens will continue to converse without actually recruiting.

For exact mechanics and chances of recruitment, see [[#Recruitment]].

==== Will ====
Enslave{{IdeologyIcon}} and Reduce Will{{IdeologyIcon}} work analogously to Recruit and Reduce Resistance, except that the end result is that the prisoner becomes a [[slave]].{{IdeologyIcon}} A prisoner starts with much less will than they do resistance.

==== Tame ====
A [[wild man]] can be arrested and imprisoned. However, they must be [[tame]]d using the usual [[animal]] mechanics, rather than being recruited as a prisoner. Once tamed, they will join the colony as a colonist.

=== Release ===
Wardens will take the prisoner outside your colony, and free the prisoner. "Outside the colony" means beyond your outermost line of connected walls, so it could be just out the door, or across most of the map if your defenses stretch that far.

Releasing a prisoner of another faction will give a [[goodwill]] boost of +12. In order to count towards goodwill, the prisoner must successfully leave the map healthy, with any wounds tended to. Prisoners that can't walk can't be released. Pirates and savage tribes do not interact with goodwill, so releasing them has no effect.

Releasing a colonist will have them rejoin your colony. [[Slave]]s retain their home faction.

=== Execute ===
Wardens will cut a prisoner's neck immediately, killing them without fail. This is a different action from the ''Prisoner execution'' [[ritual]].

Executing guilty prisoners - those who have harmed the colony in 24 hours - give a {{--|2}} [[mood]]let to non-[[Psychopath]] colonists. Executing a non-guilty prisoner increases the penalty to {{--|5}}.

Colonists following an [[ideoligion]]{{IdeologyIcon}} with the [[Ideoligion#Execution|Execution: Respected if Guilty]] precept instead gain a {{+|3}} [[mood]]let for executing a guilty prisoner, with the executioner gaining {{+|10}} mood instead. The [[Ideoligion#Execution|Execution: Required]] precept gains the same moodlets (but shorter) for executing anyone. If the execution was desired by precept, then fluid ideoligions gain a development point.

Executed prisoners who are then [[Resurrector mech serum|resurrected]] will have the execute toggle deselected to prevent their immediate re-execution.

=== Convert ===
{{Ideology|section=1}}
Attempts to [[Ideoligion#Conversion|convert]] the prisoner to the warden's own [[ideoligion]]. The target ideoligion can be selected, which will only allow wardens of that ideoligion to convert.

This is functionally the same as [[Ideoligion#Conversion|regular conversion]] that can occur randomly between colonists, except that it is done on a regular basis.

=== Hemogen ===
{{Biotech|section=1}}
{{Stub|section=1|reason=There are protections to prevent prisoners getting farmed when it will kill them. These protections and any exceptions need to be detailed}}
==== Bloodfeed ====
Pawns with the [[Bloodfeeder]] [[gene]] will automatically drink the blood from a prisoner, directly. This happens when a bloodfeeder is below their desired Hemogen and if the bloodfeeding would not kill the prisoner.

==== Hemogen farm ====
Automatically orders the operation extract [[hemogen pack]] when a prisoner's [[blood loss]] level reaches 0. In addition to creating drinkable hemogen, it also trains the surgeon's Medical skill.

=== Other ===
* Prisoners can be escorted by a warden to a prisoner bed. Prisoners can be escorted to a prisoner medical bed, if needed, without a risk of escape.
* Prisoners can initiate social fights with other prisoners.
* Prisoners can be given any number of medical [[operation]]s. This includes injecting [[drug]]s, installing [[artificial body parts]], [[organ harvesting]], and more.
* Prisoners are valid targets for a [[gene extractor]],{{BiotechIcon}} [[subcore softscanner]],{{BiotechIcon}} or [[subcore ripscanner]].{{BiotechIcon}}
* Prisoners can be sold to a [[faction base]] or slaver for [[silver]], or a royal tribute collector{{RoyaltyIcon}} for [[honor]]. Colonists who do not like slavery will get a -3 moodlet, modified by [[ideoligion]].{{IdeologyIcon}}
* If a prisoner dies, the mood penalty depends on their cause of death. "Intentional" means, like violent combat, count as an execution.

== Prison break ==
{{Template:Prison Break}}
{{Clear}}

== Recruitment ==
In order to start recruitment, a target pawn must first be captured, and become a prisoner. Prisoners then must be set to "Recruit" (or "Reduce Resistance" and then "Recruit") in the "Prisoner" tab of their personal info box (bottom left of screen when pawn is selected).

Then colonists assigned to wardening will "chat" with the target prisoner. This can be repeated every several hours, each one reducing [[#Resistance|Resistance]] by a predictable amount (based on the Social pawn's Social skill and the target's Mood).

=== Starting resistance ===
Each prisoner has their own recruitment difficulty based on their "Pawn Kind". See the [[Raider]] page for all pawn kinds and resistance intervals. A random value is chosen based on the Pawn Kind's resistance interval. For example, a "Warrior" will have a prisoner resistance between 5 and 9, chosen randomly.

=== Resistance reduction ===
A warden will reduce a base of 1.0 resistance per conversation. This is multiplied by:

'''Prisoner's [[opinion]] of the warden:'''
* At -100 opinion, the resistance reduction factor is 50%.
* At 0 opinion, the resistance reduction factor is 100%.
* At 100 opinion, the resistance reduction factor is 150%.

'''Prisoner [[mood]]:'''
* At 0% current mood, the resistance reduction factor is 20%.
* At 50% mood, the resistance reduction factor is 100%.
* At 100% mood, the resistance reduction factor is 150%.

'''Negotiation Ability:'''
* See [[Negotiation Ability]].

==== Word of Trust ====
The [[Word of trust]] psycast {{RoyaltyIcon}} will reduce resistance by 12, multiplied directly by the prisoner's [[Psychic Sensitivity]] and no other factors.

== Tips ==
=== Mood regulation ===
{{Stub|section=1|reason=Only some mental breaks are available to prisoners. Which? Expand on how that affects strategy and options}}
Increasing [[mood]] makes prisoners easier to recruit, and less likely to go [[berserk]]. If you want to increase prisoner mood, you can do the following:
* Give prisoners separate rooms, preferably one that isn't cramped.
* Give a prisoners a source of [[light]], a [[table]] and [[chair]], and a decent [[bed]].
* Increase the impressiveness of a room with [[sculpture]]s, [[stone tile]]s, etc.
* Give the prisoner [[fine meal]]s, [[lavish meal]]s, or even [[drug]]s.

=== Changing ideoligion ===
{{Ideology|section=1}}
If you want to change the target's [[ideoligion]], then instead try and make the prisoner upset. Lower mood reduces [[certainty]] gain, and may cause a [[Mental break#Crisis of belief|Crisis of Belief]] extreme mental break, which reduces certainty by 50%. The following can help with decreasing mood:
* Keep prisoners in a confined, dark space, without a bed or furniture. Even if there's only 1 prisoner, placing 2 [[sleeping spot]]s will create a prison barracks.
* Feed the pawn [[human meat]], [[insect meat]], [[raw food]], or [[kibble]]. Certain ideoligions can make some of these foods more desirable, but kibble is never desirable to eat.
* Keep them in [[pain]]. Inflicting [[injury]] comes at the risk of scarring or permanent damage, however, and a [[mindscrew]] {{RoyaltyIcon}} cannot be removed by traditional methods once the pawn is converted. A [[torture crown]] is a risk free way of inflicting pain, but dressing prisoners has its own difficulties.
Keep in mind that crises of belief that would drop a pawn's certainty to or below 0%, will instead convert the pawn to a weighted randomly selected ideoligion with a new certainty. While this process might select the intended ideoligion, it may not while also requiring their certainty be reduced again. If a pawn's certainty is below 50%, consider improving their mood above their extreme [[mental break threshold]] to prevent this.

It is also worth considering the individual pawn when deciding on an approach. The first concern are the [[traits]] - many traits affect the [[Global Certainty Loss Factor]] of a pawn, which in turn affect the efficacy of conversion attempts by wardens. For pawns with a high factor, traditional conversion will be effective, while forcing a crisis of belief may be all but necessary. For further details, including a list of traits that affect the factor, see [[Certainty]] and [[Global Certainty Loss Factor]].

The second concern are [[xenotypes]]{{BiotechIcon}} with the [[Aggressive]] and [[Hyper-aggressive]] genes.{{BiotechIcon}} Those with aggressive, including all [[yttakin]],{{BiotechIcon}} [[wasters]],{{BiotechIcon}} [[neanderthals]],{{BiotechIcon}} and [[sanguophages]],{{BiotechIcon}} are much more likely to have a berserk mental break, proportionally reducing the chances of a crisis of belief. Meanwhile those with hyper-aggressive will essentially never select the crisis, making pawns such as [[hussars]]{{BiotechIcon}} all but impossible to convert by crisis.

=== Prisoner suppression ===
Whenever they are [[berserk]], under a [[#Prison break|prison break]], or just escaping, sometimes you will need to subdue a prisoner. When berserk, prisoners will fight other prisoners, then will punch the weakest area (usually a [[door]]) to escape. When under a prisoner break, they can just open the door.

If you need to keep the prisoner alive, it is best to use low damage weapons and attacks - even just melee attacks with a gun or bare fists. Several unskilled pawns work better than 1 skilled one. For berserkers, you can have a skilled [[Construction]] pawn constantly repair the door. This trains Construction but is labor intensive. You can also wall the prisoner in, which will cause them to stop attacking the door and just wander around in their cell instead.

If free roaming [[animal]]s are within the prison, then [[berserk]]ing prisoners will prioritize them over breaking out. You can place [[animal sleeping spot]]s inside the prison for an automatic form of prisoner suppression. Note that animals are slightly more dangerous than humans. In addition, most animals will create a large amount of [[filth]], quickly lowering the room's quality. You may want to use [[straw matting]].

=== Unwanted prisoners ===
Enemies who have fallen in battle may not always be worth capturing in the first place. For example, a hostile with a shattered spine will require a [[bionic spine]] to replace, which may not be worth it. Unwavering prisoners can't be recruited normally, so fall under the same boat.

There are several ways to dispose of these prisoners:
* '''Release:''' The least upsetting way to remove a prisoner. Colonists will not become upset if an enemy prisoner is released, and it may increase [[goodwill]] by a small amount.
* '''Expendables:''' This is not exactly "getting rid of them", as much as making best (and ultimately temporary) use of them. Recruit them, and send them out for a long [[caravan]] that you wouldn't expend another colonist for. You can set them on a trading expedition, or scout a base/map. Or, you can use them as a meatshield. A "colonist" dying still gives a negative moodlet (-3, same as incidental death or non-guilty euthanasia), which is affected by [[opinion]]. Cut off their tongue to prevent social interaction from happening. Of course, unwavering prisoners can't be recruited.
* '''Euthanasia:''' Execute in a more humane fashion by neck cut. This costs 1x [[herbal medicine]] (or better) and trains Medical experience. An 'innocent' prisoner going through euthanasia is less upsetting than an innocent execution.
* '''Execution:''' Execute a prisoner in a raw manner. Those with an [[ideoligion]] favoring execution will enjoy it. With a fluid ideoligion, execution is a very easy way to gain development points (so long as it is Respected if Guilty).
* '''[[Human resources]]:''' Use prisoners for their parts. Artificial limbs can be removed without penalty.
** [[Organ harvesting]]: A [[kidney]] and [[lung]] can be harvested without death, and a [[heart]], [[liver]], or second kidney/lung can be taken to kill. Unless Organ Use is acceptable by [[ideoligion]], this comes with a -6 [[mood]] penalty (stacks, but diminishing) for the colony, and even more if the prisoner was killed.
** Used for a [[gene extractor]]{{BiotechIcon}} or [[subcore ripscanner]],{{BiotechIcon}} the latter of which is fatal.
* '''Selling:''' Prisoners can be sold for money at a [[faction base]] or slaver, or exchanged for [[honor]]{{RoyaltyIcon}} from a royal tribute collector. Each sold prisoner gives -3 [[mood]].

Randy Random

MortalSmurph: /* Code specifics */ Corrected mtb days explanation

{| align=center
| {{AI Storytellers Nav}}
|}
{{Infobox main|ai
| name = Randy Random
| image = Randy.png
| description = Randy doesn't follow rules. He'll generate random events, and he doesn't care if they make a story of triumph or utter hopelessness. It's all drama to him.
| type = AI Storytellers
}}

'''Randy Random''' is a wild storyteller whose main characteristic is triggering challenges at any time, to the extent of launching several dangerous threats all at the same time or consecutively. Randy also multiplies his [[raid points]] by 0.5x to 1.5x, resulting in both easier and harder difficulty raids than you should be receiving. It is possible to receive back-to-back raids at 1.5x but also a quadrum of relative peace with a 0.5x raid.

In the long-term, Randy will average about as many threats sent as Cassandra.

== Analysis ==
Randy produces more erratic gameplay than Cassandra and Phoebe. Because Randy can apply a random raid size multiplier ranging from 0.5 to 1.5, the raid difficulty progression under Randy can appear inconsistent. His lack of on/off cycles and a cooldown for major threats allows him to generate periods both more intense and more Peaceful then Cassandra and Phoebe possibly could.

== Code specifics ==

Randy fires events on average every 1.35 days. Not all events are fired via Randy. Some events, like quests, are fired separately and not controlled by Randy's firing mechanism.

Randy checks if an event can be fired once every 1,000 game ticks. That 1,000 game ticks is the equivalent to 60 times a Rimworld day or 2.5 times a Rimworld hour. If Randy has not fired a major threat after 13 days, the next Randy fired event becomes a major threat.

Events/Odyssey

2026-06-07T01:12:49Z

MortalSmurph: /* Volcanic debris */ Roof -> Overhead mountain.

{{Odyssey}}
{{Main|Events}}
The [[Odyssey]]{{OdysseyIcon}} DLC introduced new incidents specific to biomes or map features.

== Misc Odyssey ==
===Seasonal flooding ===
Rainfall upriver is causing the river to swell. The flooding will subside after several days.

Approximately 12 cells of land along rivers can become Shallow Flood Water. Any non-tree plants and flooring in those cells are destroyed. Fences, Barricades, Sandbags, Walls, Natural Stone walls, Graves, and similar can block the rising flood waters.

Seasonal Flooding must occur on river maps, with a temperature of at least -7 C, and in Spring or Permanent Summer. Water can rise for up to 4 days.

Seasonal Flooding recedes after another 4 to 6 days, or if temperatures drop below -7 C. When the flood recedes, the terrain returns to its original type, usually very rapid.

Seasonal Flooding may only occur once every 40 days.

=== Gill rot ===

Fish populations are slowly declining due to a parasitic fungus known as gill rot. The fungus is harmless to people.

During Gill Rot, 15% of maximum Fish Population per body of water is lost per day. Gill Rot lasts 3 to 6 days. Gill Rot can only occur after day 45 and can only occur every 45 days. Gill Rot must occur on a map with Fish.

=== Orbital debris ===

A cloud of orbital debris is hurtling towards your position and will impact within seconds. Get your colonists under a roof.

Orbital Debris can only occur in Space, but it will also occur on the planet itself if it's selected in custom scenario. After a short delay, 12 to 16 pieces of debris will impact into non-roofed cells and damage any pawns nearby. The impact will leave a crater, and damage nearby objects around it.

=== Volcanic ash ===

Ash from a nearby volcanic eruption is filling the sky. The sun is blocked and the acrid air burns the lungs. The cloud will last several days.

Volcanic Ash completely blocks out the sun, causes a -3 thought Volcanic Ash and -10% breathing to anyone not under a roof.

Volcanic Ash can only occur after day 15 and once every 30 days. The event can occur outside the lava zones in custom scenarios.

== Lava field==
=== Volcanic debris ===

A nearby volcanic eruption is showering the region with molten lava!

8 to 12 pieces of Volcanic Debris land in cells without overhead mountain. A small pool of temporary [[lava|shallow lava]] is created. Pawns can walk through this shallow lava. After a few days, the shallow lava turns into removable [[lava|Cooled Lava]]. When the cooled lava is removed using the remove flooring command, the terrain returns to original type.

Volcanic Debris can only occur after day 15 and once every 30 days.

=== Lava Emergence ===
Lava is emerging from cracks in the ground! It'll continue to pool until it creates a small lake. It will then take several days to cool, after which it can be removed.

The lava will make temporary shallow lava that pawns can walk through. After a few days, the [[lava|shallow lava]] turns into removable [[lava|cooled lava]]. When the cooled lava is removed using the remove flooring command, the terrain returns to original type.

The lava emergence can flow over any pathable terrain and over chunks or items on the ground. The lava cannot flow through walls, doors, fences, barricades, graves, columns and other objects.

The shallow lava can light adjacent flammable objects on fire. Only specific for the [[lava field]], it will not occur in custom scenarios outside of it, even if the incident occurs at specific interval or a single time.

=== Lava Flow ===
Lava has begun to pour into the region, flooding the low-lying volcanic rock. Keep your colonists out of harm's way!

Lava will emerge from the edge of the map and will flow only over volcanic rock and [[lava|cooled lava]] terrain. {{Check Tag|Verify|If it only flows over old lava tiles, why is cooled lava removable? Similar to floodwater instead?}} The Lava Flow will create [[lava|shallow lava]] that is pathable and leave behind [[lava|cooled lava]] terrain after a few days. The lava cannot flow through walls, doors, fences, barricades, graves, columns and other objects.

The shallow lava can light adjacent flammable objects on fire.

Lava Flow can only happen once every 12 days.

==Glowforest==
===Bioluminescent spores===
Some variety of fungus is blossoming and releasing bioluminescent spores! The spores are strangely beautiful and pose no danger.

All Colonists, even blind colonists, on the Glowforest map with spores gain a +4 Biolumenentic Spores thought.

Biolumenescent Spores can only occur again after 15 days. The spores last between 8 and 18 hours.

===Boomshroom Sprout===
A cluster of explosive boomshrooms has sprouted nearby! These mushrooms only grow in darkness. Once they mature, they can be harvested for chemfuel. Be careful - mature boomshrooms explode if damaged.

==Grasslands==
===Drought===
Due to a recent lack of rain, a drought has begun.

During a drought, rain, rainy thunderstorm and similar weather events are disabled. Crops grow at 30% of their growth speed unless inside [[hydroponics]]. Despite the event letter claiming that "crops grown outside" are affected, crops grown indoors still get the growth speed penalty.

Droughts last 6 to 10 days. Before a drought appears, a "Drought (Initial)" event had already occurred unannounced.

===Drought (Initial)===
The hidden prequel event to a Drought. During Drought (Initial) no rain can occur. The rain that can be caused by large fires is also prevented. Drought (Initial) lasts 4 days and always leads to the standard Drought event.

Drought (Initial) can only fire again after 40 days.

Mechanoid cluster

2026-04-28T14:14:01Z

MortalSmurph: /* Misc tactics */

{{Royalty}}
[[File:Mech cluster deploying.gif|thumb|500px|right|A large mech cluster deploying with a [[toxic spewer]].]]

'''Mechanoid clusters''' are a [[major threat]] introduced in the [[Royalty DLC]]. Mechanoid clusters consist of various buildings, including [[condition causer]]s that will hinder your colony, as well as [[mechanoid]]s. They may generate through [[storyteller]] mechanics or [[quest]]s, or deployed willingly through an [[orbital mech cluster targeter]].

== Generation ==
Mech clusters will attempt to spawn by selecting a tile and seeing if the cluster can fit there. It will repeat this twenty times attempting to spawn a mech cluster. If it succeeds, the mech cluster will be spawned. If the mech cluster does not fit in any of the twenty tiles it attempted to spawn in, it will select any empty tile and spawn a mech cluster. This means for bigger bases, a mech cluster is likely to spawn partly inside the base. For very large mountain bases, if it cannot find any other valid spaces, the mech cluster is likely to land in the mountain. Landing on overhead mountain will destroy the drop pods immediately and cause large chunks of the roof to collapse which can crush items and colonists below.

Mech clusters can only generate with at least 400 [[raid points]].

== Summary ==

=== Activation ===
Mechanoid clusters will initially arrive dormant, with the mechs and offensive buildings will wake up under specific triggers. The entire cluster will wake up once any mech or building takes any direct damage, or when building within a 2 tile distance to a mechanoid or any non-wall, non-barricade building. Mech clusters may also appear with a [[proximity activator]] or [[count-down activator]], which will wake the cluster up. Damage to steel walls from spreading [[fire]] will '''not''' wake up the cluster.

[[Condition causer]]s and [[auto-mortar]]s will have an activation timer separate from the cluster itself, and may be active immediately. Damaging the condition causer will not activate the causer itself but will wake the rest of the cluster.

=== Behavior ===
By default, awake mechanoids will attack enemies within range, but will not stray too far from the cluster, similar to a [[crashed ship part]] or [[infestation]].

For non-quest clusters, if any structure (including walls or barricade) falls below 50% hit points, mechanoids will attack as if they were a standard [[raid]]. Quest mech clusters do not have this 50% hit point attack threshold behavior, and will only attack once all mech cluster buildings are destroyed.

Defeating a mechanoid cluster (destroying all mechs and harmful buildings) grants a {{+|4}} ''Defeated mech cluster'' [[mood]] buff to all colonists and colony-owned [[slave]]s{{IdeologyIcon}} on the map. This buff lasts 10 days and stacks up to 5 times.

== Analysis ==
Tackling a mech cluster by charging in head-on is unwise, as the mechanoids will have the advantage of terrain and turrets while colonists will not. Preparation is recommended, from shelling it with [[mortar]]s to using [[cover]] and [[EMP]] to give colonists as much advantage as possible. Melee is also feasible, with the only melee mechanoid being the [[scyther]].

Alternatively, it is possible to ignore the mech cluster and live under it conditions, depending on what the problem causer is, so long as colonists' [[allowed area]]s forbid going near the cluster. For example, a cold [[climate adjuster]] may not be dangerous if the colony already has a [[greenhouse]] and warm clothing. Clusters without a condition causer or with an irrelevant condition causer may be ignored, and potentially beneficial as the mechs will fight any human [[raider]]s that come across it.

=== Effective tools ===
* [[Blind smoke]] ([[smoke launcher]], [[smokepop pack]]s, the [[Smokepop]] psycast): Smoke prevents turrets from targeting pawns entirely, making it much easier to approach and damage the cluster. If/when the mechanoids are lured out away from the cluster, smoke will make dealing with turrets 100% safe.
* [[EMP]]: EMP damage stuns all mechs and turrets. If there is no proximity activator, a user of [[EMP grenades]] can be placed in a key location and stun effectively. [[EMP shell]]s can work from a distance.
* [[Invisibility]]: A pawn that can self-cast invisibility multiple times in a row can go in, destroy any problem causers and automortars, and get out unharmed.
* Bomb type damage ([[mortar]]s, [[triple rocket launcher]]s, aerodrone [[permit]] strikes, [[frag grenade]]s): Bomb damage deals 4x damage to impassable buildings, and certain explosives like mortars have long enough range to attack safety from a distance.
* [[Firefoam pop pack]]s: These immediately extinguish fires from [[auto inferno turret]]s and [[centipede burner]]s, which can otherwise be dangerous to pawns.

=== Walls and Cover ===
If a mechanoid cluster has not yet activated, your colonists can prepare buildings to make it easier to handle. Building a wall between the cluster and your base will prevent turrets from shooting your colonists, and allow your troops more flexibility to maneuver while dealing with mobile units. Be careful to remove the [[Home area]] around the wall so colonists don't decide to go cleaning or firefighting just in front of the wall. (Designating allowed areas for your colonists can also help keep them safe.)

If you intend to use direct fire attacks, you should take care not to wall the cluster away entirely, or you may be unable to disable the turrets. Leave a way for your troops to shoot at the cluster from cover, and provide a protected path to access this site.

If a mech cluster is well beyond your colony's abilities, you may be able to wall it in entirely while you prepare better armament. If the cluster is unable to harm you, such as by way of a condition causer or auto-mortar, you may even opt to leave it alone entirely, until a different group of uninvited guests, such as [[Pirates]] or [[Insectoids]], wanders into the cluster and softens them up for you. Be careful with friendly factions and any incoming [[caravan]]s however.

'''When constructing anything, be careful not to build within 2 cells of the cluster buildings or sleeping mechanoids, as this will activate it, proximity activator or not.'''

=== Luring mechs ===
Unless the cluster spawned via [[quest]], once any building of a mech cluster is destroyed, the mechanoids will pursue and attack colonists en masse, regardless of distance from the cluster. This will lure the mechs into a [[killbox]] or any number of defensive fortifications, and more importantly, lure mechs away from the cluster's turrets. This makes it significantly easier to deal with the cluster, as the turrets alone can be trivially destroyed with the help of a [[smoke launcher]].

Destroying buildings can be done via [[mortar]] fire or other long-range attacks like [[triple rocket launcher]]s, planting [[IED trap]]s while the mechs are dormant (don't place them within 2 tiles of a building or near a countdown activator) and setting it off, via [[invisibility]], and so on.

If the mechs won't leave the cluster, it is possible to lure the mechs, attack for a bit from long range, then back off until the mechs retreat. Using the [[invisibility]] + [[skip]] psycasts to repeatedly attack mechs, back off, recover neural heat and psyfocus, and attack again is also an effective tactic.

=== Activation ===
Instead of damaging a building and luring the mechs towards your base, or using mortar fire, it is possible to deal a powerful first strike before the mechs wake up.

It is possible to get up close if there are no proximity activators. If getting up close, [[EMP grenade]]s, [[frag grenade]]s, and melee pawns in general are effective at disabling mechs and damaging buildings. The [[Berserk]] or [[Berserk pulse]] psycast can be used on a [[centipede]] to act as a durable distraction.

[[Triple rocket launcher]]s can deal great damage if it has a clear line of fire to important buildings and/or mechanoids. [[Doomsday rocket launcher]]s are similar but less effective.

=== Mortars and indirect fire ===
For mech cluster without a mech high-shield, [[mortar]]s are a great, low risk way of dealing with them, especially as the mechanoids linger in a small, confined area. Prolonged shelling can easily destroy mech clusters and weaken the mobile mechanoids substantially before triggering them to attack your colony (where you can take advantage of your base defenses). The main disadvantage of mortars is that they are expensive

For mech clusters with a mech high-shield, you can either try to destroy the shields first with snipers, or simply break the shield using [[EMP shell]]s. Firing an [[EMP shell]] into the shield will disable the mech high-shield for {{Ticks|1080}} time, allowing other mortars shells to hit the cluster, potentially destroying the shield before it comes online again. The most used strategy for EMP shells is to set all mortars to "hold fire" then "set target" to where you want to hit. Select only the mortar with EMP shell and click "hold fire" again, wait one second and select all the other mortars loaded with high explosive shells (as many as you can) and also click "hold fire" again. This will assure the EMP shell is fired first, disabling the mortar shield, and allowing all the other shells to hit.

Other forms of long-range explosives are similarly effective to mortars. If a colonist has the appropriate [[Titles#Permits|imperial permits]], they can call down either an aerodrone strike or an aerodrone salvo. [[Orbital bombardment targeter]]s can also work to take out a mech cluster. [[Tornado generator]]s are great at taking out a single building, but are too unreliable beyond that.

All mechs and mech buildings (except [[wall]]s and [[barricades]]) are fireproof, so [[incendiary shell]]s are ineffective.

=== Direct Fire Tactics ===
Long range weapons like the [[sniper rifle]] can be used to take out important buildings slowly, or at least lure the mechs into attacking, from a distance. Smoke from a [[smoke launcher]] or the [[smokepop]] psycast is heavily recommended, as it will prevent long ranged turrets from locking on.

Building cover, having pawns with general weapons like [[assault rifle]]s, and using smoke or otherwise blocking the turrets can also be effective with enough firepower.

Depending on the damage you inflict, and the mechanoids' behavior, you may have to decide between withdrawing to your base or mounting a shootout from your forward positions.

=== Misc tactics ===
* Roofing over Automortars will now wake up the mech cluster. In previous patches, one could roof over an automortar without waking up the mech cluster.

=== Tactics to avoid ===
* While you may benefit from [[Defense_tactics#Melee_blocking|melee blocking]] as you face mechanoids, you should not destroy effectors with melee weapons. They are liable to explode, harming the troops who are attacking them.
* Using an imperial permit to call a light trooper squad can help you deal with mobile units, but if they are exposed to extensive turret fire they probably won't last very long.

== Trivia ==
* All mech cluster buildings, not including the condition causers, not only have a [[Flammability]] of 0%, but also take no damage from attacks with the [[Damage Types|Flame]] damage type. This is in contrast to, for example, a [[stone]] [[wall]] which will not be ignited by [[molotov cocktails]] but will take the 10 flame damage from the initial attack.
* Mech Clusters do not spawn elite mechanoids normally summoned by a Mechanitor in [[Biotech]].

== Version history ==
* [[Version/1.1.2575|1.1.2575]]:
** Implement mech shield generator charge cycle. Shields now go down for a random day every 10 days
** Condition causers and mortars now sometimes take several days to initiate threatening the colony.
** Make mortar/bullet shields shut down when the cluster is defeated.
* [[Version/1.2.2753|1.2.2753]] - Ensure all the mech cluster buildings wake up once it was attacked
* [[Version/1.4.3523|1.4.3523]] - Fix: Placing 0 work buildings beside/on mechanoids could wake them up, which could trigger them on command.

MortalSmurph: /* Capabilities */

{{Biotech}}
{{About|children of age 3 and up|pregnancy and babies|Reproduction}}
'''Children''' are added by the [[Biotech (DLC)| Biotech DLC]]. They are smaller, slower, and less capable of work when compared to adult pawns, but gain skills as they age.
{{TOCright}}

== Acquisition ==
{{See also|Reproduction}}
* Having a [[baby]] age up to 3 or beyond.
* Purchasing them from [[Trade#Slaver|slavers]].
* Most [[quest]]s and [[event]]s where an adult colonist would join.

Note that [[raid]]s will not have children, unless you enable it in the [[AI Storytellers#Child enemies|storyteller settings]].

== Summary ==
Children are human pawns from 3 to 13 years old. Younger pawns are [[babies]]. Older pawns, between 13 and 18, are teenagers - considered adults for most purposes.

Children have important growth moments at ages 7, 10, and 13. These give the pawn access to new work types, as well as the choice of [[trait]]s and passions. Giving a child access to Learning increases the possible choices. See [[#Development]] for more details.

=== Age ===
Age is measured both biologically and chronologically. Biological age represents how far a pawn has grown physically and mentally. Chronological age represents how long a pawn has existed since their birth; their "true" age, so to say. Since chronological age has no direct gameplay effects, all listed ages are in biological years unless stated otherwise.

By default, children biologically age at 400% speed. Upon reaching 11, their aging will linearly slow from the [[AI Storytellers#Child aging rate|child aging rate]] until they reach 20, where they'll age at the [[AI Storytellers#Adult aging rate|adult aging rate]], or 100% by default. Their aging can be altered by changing the [[AI Storytellers#Biotech|storyteller settings]].

At the default aging rates, it takes about 3.30 years (~198 days) for a child to grow from birth to age 13, and about 5.38 years (~323 days) to go from birth to age 18. In total, a child takes about 6.91 years (415 days) to go from birth to age 20, of which 2.75 years (165 days) is from birth to age 11.

[[Growth vat]]s can be used to very quickly age pawns up to age 18, after which they will get forcefully ejected. A pawn in a [[growth vat]] will age at a constant 20x speed, unaffected by any other aging factors except for the [[Growth Vat Occupant Speed]] stat{{IdeologyIcon}}, as long as it has access to [[power]] and [[nutrition]]. However, if used to speed up the "Child" stage (ages 3-13), then the vat will impact the child's [[#Development|Development]]. Conversely, the [[ageless]] [[gene]] will linearly slow aging from 13 until stopping entirely at 18.5. Growth vats ignore the ageless gene.

For more explanation of aging rate, see [[#Aging]].

=== Capabilities ===
Children as young as 3 can wield [[weapon]]s and are valid for any [[Reproduction|non-reproductive]] [[surgery]], including [[organ harvesting]]. However, children are limited to child-sized clothing like the [[kid pants]] and [[kid parka]], and can only do certain types of work. They receive penalties to [[Global Work Speed]], [[Move Speed]], and more, scaling with age. Due to their body size, they have less health, can store less [[nutrition]], and receive stronger effects from [[drug]]s. Instead of Recreation, children have [[#Learning|Learning]], which gives them more options for each growth moment.

Teenagers wear adult clothing, have access to all work, and lose their Learning need. However, they can only reproduce once they reach 16. And, teens retain a small penalty to work speed and body size until they reach 18, where they become full adults and all penalties are removed.

See [[#Stats|Stats]] for a full breakdown of stat penalties.

=== Noncombatants ===
Luckily, children (until 13) do not always have to participate in combat. Children who are unarmed and have not been [[draft]]ed in 24 hours are very low priority targets for enemies.{{Check Tag|Verify mechanic|Exact mechanic unknown?}} Adult colonists will virtually always be targeted over a noncombatant. If children aren't in the line of sight of enemy fighters, they won't be hunted down during an attack.

However, children are still ''able'' to be targeted. This is in contrast to [[pen animal]]s, who enemies will never attack intentionally. If a raider has no other targets available, a "noncombatant" child will be attacked. Hungry predators have no regard for this mechanic, and will target your children if they are nearby. In any case, a child in the way of a firefight can be hit by stray shots and [[friendly fire]].

=== Mood ===
Children receive a [[mood]]let for simply being young: at age 3, {{+|16}} '''Childlike joy''', at age 6, {{+|12}} '''Childlike wonder''', age 8, {{+|8}} '''Childlike enthusiasm''', and at age 10, {{+|4}} '''Childlike confidence''', finally lost at age 13. Children are happy when their parents are happy ({{+|6}} for each parent), and parents are happy when their children are (also {{+|6}} for each child). Other than that, most regular moodlets apply to them.

Adult colonists receive a {{+|2}} ''Happy youngsters'' for each child colonist with 60 mood or higher, stacking up to +6. They will receive a -2 mood for each child colonist with 35 mood or less, stacking up to -6. Most receive a {{--|6}} moodlet for killing an innocent child.

== Development ==
=== Learning ===
Children have a '''Learning''' [[need]], which replaces Recreation. They satisfy the need by satisfying one of their [[#Learning desires|learning desires]], which they usually have 2. The need gives mood buffs or debuffs, [[Recreation#Recreation_thresholds|analogous to Recreation]] at the same level, and, most importantly, it increases their [[#Growth score|growth score]].

When a child decides what to do in accordance with their [[schedule]], they may choose learning. The following conditions should be met for the child to actually start learning:
* The current schedule hour is set to anything but "Work". Notably, for the "Sleep" schedule assignment, learning has a higher priority than sleeping (unlike adults, who go to sleep if the Sleep need is below {{Bad|75%}}, children prefer learning to sleeping, if possible (see other limitations)).
* Learning need is below {{Bad|90%}}.
* A learning desire can be satisfied (see descriptions of individual desires for possible limitations). If both desires can be satisfied, one is randomly selected.
* Food need is {{Good|≥34%}} and Sleep need is {{Good|≥38%}}.

The mood level doesn't matter.

Once learning begins, it will continue until either Learning need reaches {{Good|99.9%}} (visible as {{Good|100%}} due to rounding), or it is interrupted (by the child needing to eat or sleep, or being drafted, or the Learning type becoming invalid—e.g., for work watching, if all adults have stopped doing any watchable work types). After an interruption, if their Learning is below 90%, they may resume learning, but if it's above 90%, they won't—instead doing work or idling, until it drops below 90% again.

Learning is '''not''' interrupted if the child loses desire for the currently performed learning type.

The speed with which children fulfill their Learning need is affected by the [[Learning Rate Factor]] stat.

=== Learning desires ===
At any one point, a child has 1 or 2 of the learning desires, listed below. They are shown as pictograms above the Learning need bar. When a baby reaches age of 3 and becomes a child, they get the first desire which is randomly selected. Then, they repeatedly gain a random new desire in random time intervals ranging from {{ticks/gametime|20000}} to {{ticks/gametime|40000}}, averaging to 2 desires daily. The desires form a queue with a maximum length of 2 (the new desire is added to the end of list, and if the number of items exceeds 2, the first item is removed).

When a new desire is selected, it never repeats an active one (including the one that is to be removed from the queue). Also, ''Radio talking'' isn't chosen before [[Microelectronics]] is researched; this is the only safeguard against choosing a desire which is currently impossible to satisfy. Desires which are not ruled out by these restrictions have equal probability of being chosen, except ''Lesson taking'', which has {{Good|x2.5|normal}} higher weight (probability) than the others. It is perfectly possible to get a learning desire which is impossible to satisfy. Each of them has a number of blocking conditions, and the mentioned Microelectronics research thing is the only condition that is consciously avoided.

==== Floor drawing ====
Children draw pictures on the floor in various places. This does not require any additional supplies and can occur on anywhere within or near home area. The drawings can be cleaned up the same way as any other dirt. Unlike other types of filth, however, it does not have any effect on [[beauty]].

==== Lesson taking ====
Requires an awake adult that is capable of teaching (a teacher). The child (student) will sit at a [[school desk]]. The teacher can be prioritized to teach the child on a currently usable skill (e.g., when age 4 this can be Shooting, Melee, or Social), increasing the child's respective skill level. The speed at which the child learns can be increased by up to 60% by adding up to 3 [[Blackboard]]s near the school desks at which the lesson takes place. It also trains the teacher's Social skill.

Teaching lessons improves the child's opinion of the teacher, for {{+|8}} ''Taught me a skill''. The teacher will additionally raise their opinion of the child: {{+|4}} ''Listened to my lesson''.

A colonist can be a teacher if they:
* Are an adult
* Are awake
* Have Food need {{Good|≥34%}} and Sleep need {{Good|≥38%}}
* Are capable of childcare and has it enabled in the Work menu
* Can [[Talking|talk]]
* Belong to the player's faction (neither [[guest]] nor quest lodger)
* Can reach the child avoiding deadly dangers{{Check Tag|Clarify|What dangers exactly?}}
* Are not [[drafted]]
* Are neither in a [[mental break]] nor [[Mental break#Special|mental state]]
* Are not [[downed]]
* Are not burning
* Don't have a lord{{Check Tag|Clarify|This condition is checked in the game's code, but it is unclear how a colonist may have a lord.}}

==== Nature running ====
Children run around outside, similar to the adult "Going for a walk" activity. Care must be taken as nearby predator hunt or potential raid can occur near them, as they tend to run outside the safe zone near the edge. Children can ignore [[allowed area]]s while "running", but will quickly go back.

Experimentation seems to indicate that{{Check Tag|verification needed}}:
* It needs to be a number of tiles away from anything player-owned (floors don't count), 43 tiles of space is enough but less is possible using a very specific pattern (see image)
* These tiles need to be as empty as possible, ideally when building under overhead mountain a collapsed rocks or unmined tile 6 spaces away from any other is sufficient (it's unclear how much wiggle room is there)
* There's no need for this tile to be outdoors, however dev placed natural tiles such as collapsed rocks are counted as artificial somehow

The dimensions of the image are 36x36, 41x36 (vertical) and 48x36 (horizontal). 41x48 and possibly 48x41 should work as well with minimal wasted space.

==== Radio talking ====
The desire doesn't appear before [[Microelectronics]] is researched, which is required for building the [[comms console]]. A console is used by the child for chatting with people over the radio. The child will stop radio talking if the console is used for other purposes, such as trading with a trade ship or contacting another faction.

The child uses the nearest comms console, which is:
* Powered
* Allowed
* Reachable, avoiding deadly dangers{{Check Tag|Clarify|What dangers exactly?}}
* Not reserved by another pawn

If no such console is found, the desire cannot be satisfied.

==== Reading ====
{{stub|section=1|reason=Lack of mechanics - also propagate to [[books]] and the pages for the types of books.
Reports that:
* The normal effects of books still apply to children reading books - they gain skills from textbooks and provide research from schematics
* That because you can force children to read, unlike other learning types, so when their learning is lagging you can force them to read to catch up.}}
Children can read [[books]] to fulfill their learning need. If you notice a child is behind in learning progress, wait until reading appears as one of their learning needs. As reading can be forced manually, you can keep the child’s learning at 100% (with smaller dips for eating and sleeping) by forcing reading even when learning is above the 90% threshold.

The normal effects of a book still apply to children, allowing them to increase their skills they have access to while reading, allowing their skills to be even more developed.

==== Sky dreaming ====
Children lay on the ground and watch the sky, much like adults that are cloud watching.

Bad [[weather]] does '''not''' prevent sky dreaming.

Experimentation results suggest that for a spot to be viable for sky dreaming it must have no artificial tiles or objects in the ground within 36 tiles (floors are fine so concrete can be used to get them away from danger faster). This distance seems to be direct (as the crow flies) rather than via squares (manhattan distance) so it might be difficult to adjust perfectly outside trial and error for a "skydreaming shelter" for children.{{Check Tag|Verification needed}}

==== Work watching ====
Children that are work watching will follow an adult, who does standard work, and slowly gain the corresponding skill (e.g. Plants when watching plant work). Children will only watch work types that use a skill they can use themselves (e.g. children under 7 will only watch Social work, such as childcare and wardening; they ''do'' watch wardening even though they can't perform it until age 10). Children gain skill even when watching the unskilled parts of skilled work (e.g. they gain Crafting skill when watching stonecutting and Medical skill when watching a doctor feed patients).

=== Growth score ===
Each day, children will raise their growth score (shown at the bottom of the screen when a child is selected) proportionate to their Learning need. Growth points are not gained when the Learning need is frozen, such as in a [[growth vat]] or [[cryptosleep casket]].

The growth score can pass through 8 tiers of learning, and each will grant more rewards during a child's growth moment. Tiers give you more flexibility in choosing a child's next trait and gives more passions. Once a growth moment has passed, the child's growth tiers will reset to 0, and you'll need to keep them learning to gain more rewards. A child with constantly fully-satisfied Learning need would achieve a hypothetical maximum of 180 growth points, but 162 is the highest value displayed.

Growth point gain is directly proportional to the time spent between growth moments, so that average Learning for each growth tier remains constant. Under the default settings, children from 3-7 gain up to 3 growth points per day, and children from 7-10 and 10-13 gain 4 growth points per day. Changing the child aging rate in storyteller settings adjusts the growth point gain accordingly. Changes to [[Global Learning Factor]], such as [[Fast learner]], have no impact on growth points or the Learning need.

The [[precept]]{{IdeologyIcon}} ''Child Labor: Disapproved'' increases Learning gain by 20%. It doesn't directly improve growth point gain, but makes it easier to keep the Learning need high.

Note that the displayed growth points are always rounded down to avoid confusion regarding thresholds.

|}

A perfectly educated child, who is always ready to begin a learning task when Learning drops to 90%, and never gets interrupted, will have Learning oscillate between 90% and 100%, averaging 95%. This gives a margin for error with respect to the maximum growth tier goal of "average Learning ≥ 90%".

The table below shows linear values required for a child to hit 162 by the next Growth Point. As the first Growth Period (3 to 7) is longer but grants fewer points per day, it has a separate set of columns.

== Growth moments ==
{{Stub|section=1|reason=Can a child ever have a backstory or trait that disables a work type?}}
[[Babies]] become children at 3, and children experience growth moments at 7, 10, and 13, allowing them to gain traits and passions. When a child hits the biological age for a growth moment, a notification will pop up that informs the player what work types the child is now capable of doing and the player to pick additional traits and passions. The number of skills and traits available to choose from increases according to the Growth tier reached by that growth moment (see above table).

What skills are chosen is completely random; working one type of work over another or what learning types are used to fill the Learning bar have no effect. A child can even gain a passion in a skill in which they have awful [[Genes#Aptitudes|aptitude]], so it's not possible to exclude undesired skills via genetic modification.

Two restrictions technically apply to the skill pool from which passion gain options are picked:
* skills disabled by backstories are removed from the pool, unless the child is enslaved at the time of the growth moment
* skills disabled by already-possessed traits are likewise removed, unless that trait is suppressed by a gene at the time of the growth moment

Only one passion can be added to a skill at a time, but passions are additive - selecting the same skill in two growth moments will result in a double passion.

Passions chosen for skills the child cannot yet use will be hidden and not appear on the bio tab, but ARE properly applied, and will become visible once the child reaches an age that allows them to use that skill. For example, if you choose to give a child a passion for Shooting, Construction, and Intellectual on their 7th birthday, the Shooting passion will be immediately visible (as children of ages 3 and up can shoot), whereas the Construction passion will not appear until the child's 10th birthday, and the intellectual passion won't until their 13th, as those are the ages at which those skills become available to children.

Only one trait can be selected per Growth moment. Traits that are mutually exclusive with previously selected traits or Genes will not appear on future Growth moments. When at least three traits are available to be chosen from, there's a 35% chance that one of the available options will be "no trait". This option can be selected if no trait is preferable to the traits offered.

You may choose their traits/passions within 48 hours of the birthday, and view their bio/health from the selection screen. During a growth moment, your child may randomly receive a new nickname, such as John Doe gaining the nickname '''Johnny''' (becoming John 'Johnny' Doe). Like other colonists, you can always change their nickname from their bio.

==== Age 3 ====
At 3, your [[Babies|baby]] transitions to childhood and additionally undergoes a growth moment. Now that your pawn is a child, they can walk and talk, wear clothes, and do basic activities. Their Play need is also replaced with a new Learning need. Because babies haven't learned anything yet, this "growth moment" does not come with traits or passions.

On their birthday, you will receive up to 2 notifications. The first is "Growth moment for <Pawn>", which may include a new nickname for your child that you'll have 48 hours to change. Both of these decisions can be postponed until their deadlines.

'' Baby '''<BABY NAME>''' has grown up and become a child! (S)He is now old enough to do the following work: <LIMITED WORK> Children do various type of work. As they get older, they become able to do more work types. They also do various child-specific recreational activities. Children need to wear specific child-size apparel. ''

With [[Ideology]]{{IdeologyIcon}}, you'll get a second notification, "<Pawn> became a child". The child will now follow one of the [[Ideoligion|ideoligions]] your colonists currently believe in, randomly determined from weightings based on who interacted with the child and how. For further details, see the [[#Ideoligion|Ideoligion]] section.

In addition, you'll have 12 hours to decide whenever to make the child a colonist or a [[slave]],{{IdeologyIcon}} depending on their birth mother, they will be a colonist or slave by default, for prisoner births they will be a colonist due to having been adopted.

'' '''<BABY NAME>''' has decided to become a follower of the ideoligion '''<MAJOR COLONY IDEOLIGION>'''. By tradition '''<BABY NAME>''', born to '''<MOTHER NAME>''' of '''<COLONY>''' (and) '''<FATHER NAME>''' of '''<COLONY>''' / unknown parents, is a colonist/tribesman/slave, but exceptions can be made... Should '''<BABY NAME>''' remain a colonist/tribesman/slave? ''

Children and their caretakers maintain any [[opinion]] modifiers that [[Reproduction#Social|arose]] during infancy, but these wear off over time. They immediately become aware of any pawns on the map that they hadn't met while babies, and gain the normal opinion modifiers for every pawn, like those based on [[Beauty (Pawn)|beauty]], [[traits]], and [[ideoligion]].

3-year-olds gain the Childhood background '''Child''': ''The story of [their] childhood is still being written.'' They also gain the ability to learn the shooting, melee, and social skills, although they start with 0 experience in them. If you started as a [[New Tribe]], then children will gain the ''Natural'' [[meditation focus]].{{RoyaltyIcon}}

==== Age 7 & 10 ====
Ages 7 and 10 are ordinary growth moments. Your child will gain a selection of passions and traits, with available choices corresponding to the [[#Development|Learning]] need. They will remain a child after either age threshold, but will gain access to more work types in the process.

==== Age 13 ====
When a child turns 13, you will receive the notification: "Child" became an adult. They are not full adults yet, but are now considered adults (or teenagers) throughout the game, and have access to all work types.

They wear adult clothing, dropping their too-small child's clothes if wearing any. Their Learning need is immediately replaced by Recreation, removing any mood effects from learning. In addition, they finally lose their {{+|4}} ''Childlike confidence''' [[mood]]let. [[Genes#Drugs|Drug dependency genes]] take effect at this age, as if they last took the drug on their birthday. They also have a chance to gain a [[Traits#Asexual|sexuality trait]], separate from the growth moment trait choice (if they receive none, they will be considered heterosexual). Some kids get special changes upon turning 13.

Children will receive the childhood [[background]] of Tribal Child or Colony Child, dependent on if you started as a [[New Tribe]] or as [[New Arrivals]]. Alternatively, they will receive Vatgrown Child if they spent enough time in a [[growth vat]] - this removes the Natural [[meditation|meditation focus]], if it was present. Their adult backstory will be set to Tribe Member or Colonist, respectively.

== Stats ==
Children and teens have various penalties to speed and effectiveness. Specifically, they have a multiplier to the following stats: [[Move Speed]], [[Aiming Time]] & [[Melee Hit Chance]] (thus, {{DPS}}), [[Arrest Success Chance]], [[Global Work Speed]], [[Market Value]], and [[Body Size]]. Each trait is affected differently by age: Global Work Speed rises steadily until adulthood, whereas Move Speed changes in jolts by life stage.

Children also have penalties to melee damage and [[Shooting Accuracy]],the stat factor [[Shooting Accuracy Multiplier (Child)|ShootingAccuracyChildFactor]] limits the maximum ShootingAccuracy of child. the meleeDamageFactor(not the stat factor of [[Melee Damage Factor|MeleeDamageFactor]]) defined in LifeStage limits the Melee Damage for Children and teens,The rates are as follows: children(3–8):0.7, preteens(9–12):0.725, teens(13–17):0.75, adult(18-): 1 . the Melee Damage will be multiplied by the meleeDamageFactor.

Note. The melee hit chance multiplier is applied not to the hit chance itself, but to the bonuses and penalties imposed on it. That is, a 3-year-old child will have ~ 50% +-5% chance of hitting both having the maximum skill level + Go-juice, and having severe traumas that reduce work and vision to 0%.

Stats that ''don't'' differ for teenagers include food consumption, Maximum/Minimum comfortable temperatures, and Filth rate. Note that teenagers also have a 1.25 multiplier on maximum nutrition, which offsets the 0.8 multiplier from their reduced body size, resulting in the same nutrition capacity as an adult.

Increasing the growth rate lowers a pawn's chronological age at any given biological age. For example, at 200% aging, it takes ~10 years to reach age 18, and at 400% aging, it takes ~5.4 years (assuming 100% adult aging speed).

A pawn with the [[ageless]] [[gene]] will linearly age slower after 13, before coming to a complete halt at 18.5. With this gene and the default rates, a pawn will take 429 days (7.15 years) between ages 13 and ''17'', then a further 362 days (~6 years) to reach age 18. A growth vat can be used to decrease this time, if so desired.

The fastest a pawn can age is in a growth vat from birth with the '''Growth vats: Essential''' [[Precepts#Growth vats|precept]]{{IdeologyIcon}}, where they reach adulthood in only ~40.5 days, after which they will age according to the set aging rate. Note that these values won't be accurate if a pawn has the ageless gene, spends time both in and out of growth vats, or the aging rates are altered in the storyteller settings mid-gameplay.

== Wearable clothing ==
Being much smaller than adults, children can only wear a limited selection of clothing, mostly consisting of headwear:

<div class="ul-column-width-200">
{{#ask: [[Lifestage::~Child*]]
| format = template
| template = Icon List
| link = none
| sort = From DLC
}}
</div>

== Ideoligion ==
{{Ideology|section=1}}
{{Stub|section=1|reason=Worked example}}
Babies have no [[ideoligion]] of their own, however when a baby becomes a child at age 3, an ideoligion is assigned to the child based on a weighted random selection.

These weights are assigned to the ideoligions of the pawns that interact with the baby. For the purposes of this calculation, this is specifically:
* {{+|0.5}} for any social interaction.
* {{+|1.0}} for carrying the baby for one hour.
* {{+|1.0}} for breastfeeding the baby for one hour.
* {{+|1.0}} for feeding the baby [[baby food]] for one hour.
These interactions are remembered forever until the baby transitions into a child.

As with all weighted selections, the more that pawns from a given ideoligion interact with the baby, the more likely the baby is to choose that ideoligion, however ultimately there is always a chance selects any ideoligion to which it was exposed.

== Analysis ==
When raised naturally and with lots of Learning time, children can very easily become powerful colonists. With the ability to choose from up to 6 [[traits]] per growth moment, the likelihood for at least one "great" trait, like [[Jogger]], [[Industrious]], or [[Quick sleeper]], per growth moment is significant. A child is very likely to have multiple ''good'' traits by the time they become a teen. Passion choice is also excellent - burning passions in any desired field are quite common. Needless to say, it'd be very rare for a randomly generated adult to match a colony raised child.

Child rearing mainly comes at a cost of time, with slightly more than 2.5 years spent in the child stage on default Child Aging Rate settings. Children do not actually require much adult supervision to grow and learn. Set an [[allowed area]] so that they won't wander too far from your base, and children will develop to become a fairly powerful colonist. However, to reach the highest growth level of 8, you need to ensure that their average learning need is at least 90% (even while sleeping). As children will not start learning unless their learning need is already below 90%, this requires more careful management, especially for children under the age of 7.

To fulfill their learning, you may need to:
* Build a [[comms console]], a [[school desk]] with 3 [[blackboard]]s, allow the child outside, and get at least 1 [[book]] to cover all possible Learning types. In practice, you can skip out on 1-2 types, and still reach growth level 8, just hope that the types you skip don't come up together at the same time.
* Constantly monitor your child's learning need and their desired activities. Sometimes they will not start learning even though their need has dropped below 90%, you'll need to diagnose the problem before it cause them to miss the growth target. If you notice a child is behind in learning progress, wait until reading appears as one of their learning needs. As reading can be forced manually, you can keep the child’s learning at 100% (with smaller dips for eating and sleeping) by forcing reading even when learning is above the 90% threshold.
* When the child is sleeping and their learning need drop below 90%, wake them up so that they can bring it up to 100% before sleeping again.
* Try not to interrupt the child before their learning need reach 100%, because they won't start learning again for a while.
* Work watching: children age 3-7 can only do work watching on social tasks, so consider ordering an adult to attempt to recruit a prisoner when a child need to work-watch.
* Lesson taking: children will not start learning unless there is an awake adult who is capable of teaching. Wake you teacher up when the child need to take lessons.
* Skydreaming: sometimes you need to draft the child and move them outside for them to start this activity

Older children that join your colony will be comparatively worse off.

===Baby stage===
As opposed to the proper child stage, the [[baby]] stage, which lasts for 45 days (3/4ths of a year), requires a notably higher amount of colonist labor. Feeding babies takes a surprisingly long time, especially if breastfed. The base duration of feeding a baby from empty is {{ticks/gametime/hours|5000}}, and babies need to be fed roughly twice a day. Between this and caring for her own needs, a mother tasked with caring for her baby can spend over half her waking hours, every day, for those 45 days. On the plus side, feeding and playing with babies can be done by children as young as age 3.

[[Growth vat]]s can be used to skip the baby stage, at the cost of nutrition and a slight mood penalty to parents. Babies don't learn, so this comes at no cost to a child's development.

=== Vats ===
{{Main|Growth vat}}
[[Growth vat]]s can turn children into working machines. It still takes a long time to grow a person - 9 days for the embryo to be born in vat, another 39 days to reach age 13, and then a further 15 days to reach 18 (if desired), for a total of 63 days from embryo to 18 (~ 52.6 days with a pro-vat [[ideoligion]]{{IdeologyIcon}}). In the meantime, the vat consumes a lot of food. Growing an embryo requires a total of 54 [[nutrition]] - 60 simple meals, or 4 colonists of food for 9 days - while a pregnant mother would consume an extra 30% nutrition for 18 days. Growing the child thereafter requires 2 colonist's of nutrition per day. Unlike with most colonists, you can use undesirable foods like [[human meat]] and [[kibble]] with no penalty.

Vatgrown pawns have 0 passions, barely any skills, and 3 random traits. Despite this, extra bodies can always be useful for tasks like Hauling and Cleaning, or fighting in general. While any [[Events#Wanderer joins|wanderer]] or captured [[raider]] is likely to be better, all three [[storyteller]]s have a population intent. As you have more people, it becomes harder to recruit more colonists. Children ignore this mechanic entirely. Therefore, growing children becomes more viable for larger colonies.

[[Gene]] modding can make vatgrown children much more powerful. For example, the [[Great shooting]] gene provides 8 Shooting skill, added on top of the pawn's "true" skill level, and a passion. If planted immediately after birth, the extra passion will nearly triple the Shooting skill bonuses from the vat. This can provide late-game colonies with a functionally infinite supply of soldiers, ignoring the game's natural population curve, and limited only by food production (and possibly lag).

Note that using vats to speed up the baby stage (0-3) and teen stage (13-18) does not penalize the pawn in any way. Babies don't learn or work, and speeding up this phase comes mostly at the cost of [[mood]]. Speeding up a teen to adulthood removes their work speed and body size penalties, though they could've done work in the meantime. However, teens in growth vats do not apply a mood penalty to their parents, as they are not "kids" anymore. Also note that unlike with [[cryptosleep]], colonists in vats have absolutely no penalty applied to them when they exit the vat. If you need them for an emergency (such as a dangerous incoming raid), they can be removed from the vat at a moment's notice.

{{About|children of age 3 and up|pregnancy and babies|Reproduction}}
'''Children''' are added by the [[Biotech (DLC)| Biotech DLC]]. They are smaller, slower, and less capable of work when compared to adult pawns, but gain skills as they age.
{{TOCright}}

== Acquisition ==
{{See also|Reproduction}}
* Having a [[baby]] age up to 3 or beyond.
* Purchasing them from [[Trade#Slaver|slavers]].
* Most [[quest]]s and [[event]]s where an adult colonist would join.

Note that [[raid]]s will not have children, unless you enable it in the [[AI Storytellers#Child enemies|storyteller settings]].

== Summary ==
Children are human pawns from 3 to 13 years old. Younger pawns are [[babies]]. Older pawns, between 13 and 18, are teenagers - considered adults for most purposes.

Children have important growth moments at ages 7, 10, and 13. These give the pawn access to new work types, as well as the choice of [[trait]]s and passions. Giving a child access to Learning increases the possible choices. See [[#Development]] for more details.

=== Age ===
Age is measured both biologically and chronologically. Biological age represents how far a pawn has grown physically and mentally. Chronological age represents how long a pawn has existed since their birth; their "true" age, so to say. Since chronological age has no direct gameplay effects, all listed ages are in biological years unless stated otherwise.

By default, children biologically age at 400% speed. Upon reaching 11, their aging will linearly slow from the [[AI Storytellers#Child aging rate|child aging rate]] until they reach 20, where they'll age at the [[AI Storytellers#Adult aging rate|adult aging rate]], or 100% by default. Their aging can be altered by changing the [[AI Storytellers#Biotech|storyteller settings]].

At the default aging rates, it takes about 3.30 years (~198 days) for a child to grow from birth to age 13, and about 5.38 years (~323 days) to go from birth to age 18. In total, a child takes about 6.91 years (415 days) to go from birth to age 20, of which 2.75 years (165 days) is from birth to age 11.

[[Growth vat]]s can be used to very quickly age pawns up to age 18, after which they will get forcefully ejected. A pawn in a [[growth vat]] will age at a constant 20x speed, unaffected by any other aging factors except for the [[Growth Vat Occupant Speed]] stat{{IdeologyIcon}}, as long as it has access to [[power]] and [[nutrition]]. However, if used to speed up the "Child" stage (ages 3-13), then the vat will impact the child's [[#Development|Development]]. Conversely, the [[ageless]] [[gene]] will linearly slow aging from 13 until stopping entirely at 18.5. Growth vats ignore the ageless gene.

For more explanation of aging rate, see [[#Aging]].

=== Capabilities ===
Children as young as 3 can wield [[weapon]]s and are valid for any [[Reproduction|non-reproductive]] [[surgery]], including [[organ harvesting]]. However, children are limited to child-sized clothing like the [[kid pants]] and [[kid parka]], and can only do certain types of work. They receive penalties to [[Global Work Speed]], [[Move Speed]], and more, scaling with age. Due to their body size, they have less health, can store less [[nutrition]], and receive stronger effects from [[drug]]s. Instead of Recreation, children have [[#Learning|Learning]], which gives them more options for each growth moment.

Teenagers wear adult clothing, have access to all work, lose their Learning need, and won't flee fire without [[Pyrophobia]]. However, they can only reproduce once they reach 16. And, teens retain a small penalty to work speed and body size until they reach 18, where they become full adults and all penalties are removed.

See [[#Stats|Stats]] for a full breakdown of stat penalties.

=== Noncombatants ===
Luckily, children (until 13) do not always have to participate in combat. Children who are unarmed and have not been [[draft]]ed in 24 hours are very low priority targets for enemies.{{Check Tag|Verify mechanic|Exact mechanic unknown?}} Adult colonists will virtually always be targeted over a noncombatant. If children aren't in the line of sight of enemy fighters, they won't be hunted down during an attack.

However, children are still ''able'' to be targeted. This is in contrast to [[pen animal]]s, who enemies will never attack intentionally. If a raider has no other targets available, a "noncombatant" child will be attacked. Hungry predators have no regard for this mechanic, and will target your children if they are nearby. In any case, a child in the way of a firefight can be hit by stray shots and [[friendly fire]].

=== Mood ===
Children receive a [[mood]]let for simply being young: at age 3, {{+|16}} '''Childlike joy''', at age 6, {{+|12}} '''Childlike wonder''', age 8, {{+|8}} '''Childlike enthusiasm''', and at age 10, {{+|4}} '''Childlike confidence''', finally lost at age 13. Children are happy when their parents are happy ({{+|6}} for each parent), and parents are happy when their children are (also {{+|6}} for each child). Other than that, most regular moodlets apply to them.

Adult colonists receive a {{+|2}} ''Happy youngsters'' for each child colonist with 60 mood or higher, stacking up to +6. They will receive a -2 mood for each child colonist with 35 mood or less, stacking up to -6. Most receive a {{--|6}} moodlet for killing an innocent child.

== Development ==
=== Learning ===
Children have a '''Learning''' [[need]], which replaces Recreation. They satisfy the need by satisfying one of their [[#Learning desires|learning desires]], which they usually have 2. The need gives mood buffs or debuffs, [[Recreation#Recreation_thresholds|analogous to Recreation]] at the same level, and, most importantly, it increases their [[#Growth score|growth score]].

When a child decides what to do in accordance with their [[schedule]], they may choose learning. The following conditions should be met for the child to actually start learning:
* The current schedule hour is set to anything but "Work". Notably, for the "Sleep" schedule assignment, learning has a higher priority than sleeping (unlike adults, who go to sleep if the Sleep need is below {{Bad|75%}}, children prefer learning to sleeping, if possible (see other limitations)).
* Learning need is below {{Bad|90%}}.
* A learning desire can be satisfied (see descriptions of individual desires for possible limitations). If both desires can be satisfied, one is randomly selected.
* Food need is {{Good|≥34%}} and Sleep need is {{Good|≥38%}}.

The mood level doesn't matter.

Once learning begins, it will continue until either Learning need reaches {{Good|99.9%}} (visible as {{Good|100%}} due to rounding), or it is interrupted (by the child needing to eat or sleep, or being drafted, or the Learning type becoming invalid—e.g., for work watching, if all adults have stopped doing any watchable work types). After an interruption, if their Learning is below 90%, they may resume learning, but if it's above 90%, they won't—instead doing work or idling, until it drops below 90% again.

Learning is '''not''' interrupted if the child loses desire for the currently performed learning type.

The speed with which children fulfill their Learning need is affected by the [[Learning Rate Factor]] stat.

=== Learning desires ===
At any one point, a child has 1 or 2 of the learning desires, listed below. They are shown as pictograms above the Learning need bar. When a baby reaches age of 3 and becomes a child, they get the first desire which is randomly selected. Then, they repeatedly gain a random new desire in random time intervals ranging from {{ticks/gametime|20000}} to {{ticks/gametime|40000}}, averaging to 2 desires daily. The desires form a queue with a maximum length of 2 (the new desire is added to the end of list, and if the number of items exceeds 2, the first item is removed).

When a new desire is selected, it never repeats an active one (including the one that is to be removed from the queue). Also, ''Radio talking'' isn't chosen before [[Microelectronics]] is researched; this is the only safeguard against choosing a desire which is currently impossible to satisfy. Desires which are not ruled out by these restrictions have equal probability of being chosen, except ''Lesson taking'', which has {{Good|x2.5|normal}} higher weight (probability) than the others. It is perfectly possible to get a learning desire which is impossible to satisfy. Each of them has a number of blocking conditions, and the mentioned Microelectronics research thing is the only condition that is consciously avoided.

==== Floor drawing ====
Children draw pictures on the floor in various places. This does not require any additional supplies and can occur on anywhere within or near home area. The drawings can be cleaned up the same way as any other dirt. Unlike other types of filth, however, it does not have any effect on [[beauty]].

==== Lesson taking ====
Requires an awake adult that is capable of teaching (a teacher). The child (student) will sit at a [[school desk]]. The teacher can be prioritized to teach the child on a currently usable skill (e.g., when age 4 this can be Shooting, Melee, or Social), increasing the child's respective skill level. The speed at which the child learns can be increased by up to 60% by adding up to 3 [[Blackboard]]s near the school desks at which the lesson takes place. It also trains the teacher's Social skill.

Teaching lessons improves the child's opinion of the teacher, for {{+|8}} ''Taught me a skill''. The teacher will additionally raise their opinion of the child: {{+|4}} ''Listened to my lesson''.

A colonist can be a teacher if they:
* Are an adult
* Are awake
* Have Food need {{Good|≥34%}} and Sleep need {{Good|≥38%}}
* Are capable of childcare and has it enabled in the Work menu
* Can [[Talking|talk]]
* Belong to the player's faction (neither [[guest]] nor quest lodger)
* Can reach the child avoiding deadly dangers{{Check Tag|Clarify|What dangers exactly?}}
* Are not [[drafted]]
* Are neither in a [[mental break]] nor [[Mental break#Special|mental state]]
* Are not [[downed]]
* Are not burning
* Don't have a lord{{Check Tag|Clarify|This condition is checked in the game's code, but it is unclear how a colonist may have a lord.}}

==== Nature running ====
Children run around outside, similar to the adult "Going for a walk" activity. Care must be taken as nearby predator hunt or potential raid can occur near them, as they tend to run outside the safe zone near the edge. Children can ignore [[allowed area]]s while "running", but will quickly go back.

Experimentation seems to indicate that{{Check Tag|verification needed}}:
* It needs to be a number of tiles away from anything player-owned (floors don't count), 43 tiles of space is enough but less is possible using a very specific pattern (see image)
* These tiles need to be as empty as possible, ideally when building under overhead mountain a collapsed rocks or unmined tile 6 spaces away from any other is sufficient (it's unclear how much wiggle room is there)
* There's no need for this tile to be outdoors, however dev placed natural tiles such as collapsed rocks are counted as artificial somehow

The dimensions of the image are 36x36, 41x36 (vertical) and 48x36 (horizontal). 41x48 and possibly 48x41 should work as well with minimal wasted space.

==== Radio talking ====
The desire doesn't appear before [[Microelectronics]] is researched, which is required for building the [[comms console]]. A console is used by the child for chatting with people over the radio. The child will stop radio talking if the console is used for other purposes, such as trading with a trade ship or contacting another faction.

The child uses the nearest comms console, which is:
* Powered
* Allowed
* Reachable, avoiding deadly dangers{{Check Tag|Clarify|What dangers exactly?}}
* Not reserved by another pawn

If no such console is found, the desire cannot be satisfied.

==== Reading ====
{{stub|section=1|reason=Lack of mechanics - also propagate to [[books]] and the pages for the types of books.
Reports that:
* The normal effects of books still apply to children reading books - they gain skills from textbooks and provide research from schematics
* That because you can force children to read, unlike other learning types, so when their learning is lagging you can force them to read to catch up.}}
Children can read [[books]] to fulfill their learning need. If you notice a child is behind in learning progress, wait until reading appears as one of their learning needs. As reading can be forced manually, you can keep the child’s learning at 100% (with smaller dips for eating and sleeping) by forcing reading even when learning is above the 90% threshold.

The normal effects of a book still apply to children, allowing them to increase their skills they have access to while reading, allowing their skills to be even more developed.

==== Sky dreaming ====
Children lay on the ground and watch the sky, much like adults that are cloud watching.

Bad [[weather]] does '''not''' prevent sky dreaming.

Experimentation results suggest that for a spot to be viable for sky dreaming it must have no artificial tiles or objects in the ground within 36 tiles (floors are fine so concrete can be used to get them away from danger faster). This distance seems to be direct (as the crow flies) rather than via squares (manhattan distance) so it might be difficult to adjust perfectly outside trial and error for a "skydreaming shelter" for children.{{Check Tag|Verification needed}}

==== Work watching ====
Children that are work watching will follow an adult, who does standard work, and slowly gain the corresponding skill (e.g. Plants when watching plant work). Children will only watch work types that use a skill they can use themselves (e.g. children under 7 will only watch Social work, such as childcare and wardening; they ''do'' watch wardening even though they can't perform it until age 10). Children gain skill even when watching the unskilled parts of skilled work (e.g. they gain Crafting skill when watching stonecutting and Medical skill when watching a doctor feed patients).

=== Growth score ===
Each day, children will raise their growth score (shown at the bottom of the screen when a child is selected) proportionate to their Learning need. Growth points are not gained when the Learning need is frozen, such as in a [[growth vat]] or [[cryptosleep casket]].

The growth score can pass through 8 tiers of learning, and each will grant more rewards during a child's growth moment. Tiers give you more flexibility in choosing a child's next trait and gives more passions. Once a growth moment has passed, the child's growth tiers will reset to 0, and you'll need to keep them learning to gain more rewards. A child with constantly fully-satisfied Learning need would achieve a hypothetical maximum of 180 growth points, but 162 is the highest value displayed.

Growth point gain is directly proportional to the time spent between growth moments, so that average Learning for each growth tier remains constant. Under the default settings, children from 3-7 gain up to 3 growth points per day, and children from 7-10 and 10-13 gain 4 growth points per day. Changing the child aging rate in storyteller settings adjusts the growth point gain accordingly. Changes to [[Global Learning Factor]], such as [[Fast learner]], have no impact on growth points or the Learning need.

The [[precept]]{{IdeologyIcon}} ''Child Labor: Disapproved'' increases Learning gain by 20%. It doesn't directly improve growth point gain, but makes it easier to keep the Learning need high.

Note that the displayed growth points are always rounded down to avoid confusion regarding thresholds.

|-

|}

A perfectly educated child, who is always ready to begin a learning task when Learning drops to 90%, and never gets interrupted, will have Learning oscillate between 90% and 100%, averaging 95%. This gives a margin for error with respect to the maximum growth tier goal of "average Learning ≥ 90%".

The table below shows linear values required for a child to hit 162 by the next Growth Point. As the first Growth Period (3 to 7) is longer but grants fewer points per day, it has a separate set of columns.

== Growth moments ==
{{Stub|section=1|reason=Can a child ever have a backstory or trait that disables a work type?}}
[[Babies]] become children at 3, and children experience growth moments at 7, 10, and 13, allowing them to gain traits and passions. When a child hits the biological age for a growth moment, a notification will pop up that informs the player what work types the child is now capable of doing and the player to pick additional traits and passions. The number of skills and traits available to choose from increases according to the Growth tier reached by that growth moment (see above table).

What skills are chosen is completely random; working one type of work over another or what learning types are used to fill the Learning bar have no effect. A child can even gain a passion in a skill in which they have awful [[Genes#Aptitudes|aptitude]], so it's not possible to exclude undesired skills via genetic modification.

Two restrictions technically apply to the skill pool from which passion gain options are picked:
* skills disabled by backstories are removed from the pool, unless the child is enslaved at the time of the growth moment
* skills disabled by already-possessed traits are likewise removed, unless that trait is suppressed by a gene at the time of the growth moment

Only one passion can be added to a skill at a time, but passions are additive - selecting the same skill in two growth moments will result in a double passion.

Passions chosen for skills the child cannot yet use will be hidden and not appear on the bio tab, but ARE properly applied, and will become visible once the child reaches an age that allows them to use that skill. For example, if you choose to give a child a passion for Shooting, Construction, and Intellectual on their 7th birthday, the Shooting passion will be immediately visible (as children of ages 3 and up can shoot), whereas the Construction passion will not appear until the child's 10th birthday, and the intellectual passion won't until their 13th, as those are the ages at which those skills become available to children.

Only one trait can be selected per Growth moment. Traits that are mutually exclusive with previously selected traits or Genes will not appear on future Growth moments. When at least three traits are available to be chosen from, there's a 35% chance that one of the available options will be "no trait". This option can be selected if no trait is preferable to the traits offered.

You may choose their traits/passions within 48 hours of the birthday, and view their bio/health from the selection screen. During a growth moment, your child may randomly receive a new nickname, such as John Doe gaining the nickname '''Johnny''' (becoming John 'Johnny' Doe). Like other colonists, you can always change their nickname from their bio.

==== Age 3 ====
At 3, your [[Babies|baby]] transitions to childhood and additionally undergoes a growth moment. Now that your pawn is a child, they can walk and talk, wear clothes, and do basic activities. Their Play need is also replaced with a new Learning need. Because babies haven't learned anything yet, this "growth moment" does not come with traits or passions.

On their birthday, you will receive up to 2 notifications. The first is "Growth moment for <Pawn>", which may include a new nickname for your child that you'll have 48 hours to change. Both of these decisions can be postponed until their deadlines.

'' Baby '''<BABY NAME>''' has grown up and become a child! (S)He is now old enough to do the following work: <LIMITED WORK> Children do various type of work. As they get older, they become able to do more work types. They also do various child-specific recreational activities. Children need to wear specific child-size apparel. ''

With [[Ideology]]{{IdeologyIcon}}, you'll get a second notification, "<Pawn> became a child". The child will now follow one of the [[Ideoligion|ideoligions]] your colonists currently believe in, randomly determined from weightings based on who interacted with the child and how. For further details, see the [[#Ideoligion|Ideoligion]] section.

In addition, you'll have 12 hours to decide whenever to make the child a colonist or a [[slave]],{{IdeologyIcon}} depending on their birth mother, they will be a colonist or slave by default, for prisoner births they will be a colonist due to having been adopted.

'' '''<BABY NAME>''' has decided to become a follower of the ideoligion '''<MAJOR COLONY IDEOLIGION>'''. By tradition '''<BABY NAME>''', born to '''<MOTHER NAME>''' of '''<COLONY>''' (and) '''<FATHER NAME>''' of '''<COLONY>''' / unknown parents, is a colonist/tribesman/slave, but exceptions can be made... Should '''<BABY NAME>''' remain a colonist/tribesman/slave? ''

Children and their caretakers maintain any [[opinion]] modifiers that [[Reproduction#Social|arose]] during infancy, but these wear off over time. They immediately become aware of any pawns on the map that they hadn't met while babies, and gain the normal opinion modifiers for every pawn, like those based on [[Beauty (Pawn)|beauty]], [[traits]], and [[ideoligion]].

3-year-olds gain the Childhood background '''Child''': ''The story of [their] childhood is still being written.'' They also gain the ability to learn the shooting, melee, and social skills, although they start with 0 experience in them. If you started as a [[New Tribe]], then children will gain the ''Natural'' [[meditation focus]].{{RoyaltyIcon}}

==== Age 7 & 10 ====
Ages 7 and 10 are ordinary growth moments. Your child will gain a selection of passions and traits, with available choices corresponding to the [[#Development|Learning]] need. They will remain a child after either age threshold, but will gain access to more work types in the process.

==== Age 13 ====
When a child turns 13, you will receive the notification: "Child" became an adult. They are not full adults yet, but are now considered adults (or teenagers) throughout the game, and have access to all work types.

They wear adult clothing, dropping their too-small child's clothes if wearing any. Their Learning need is immediately replaced by Recreation, removing any mood effects from learning. In addition, they finally lose their {{+|4}} ''Childlike confidence''' [[mood]]let. [[Genes#Drugs|Drug dependency genes]] take effect at this age, as if they last took the drug on their birthday. They also have a chance to gain a [[Traits#Asexual|sexuality trait]], separate from the growth moment trait choice (if they receive none, they will be considered heterosexual). Some kids get special changes upon turning 13.

Children will receive the childhood [[background]] of Tribal Child or Colony Child, dependent on if you started as a [[New Tribe]] or as [[New Arrivals]]. Alternatively, they will receive Vatgrown Child if they spent enough time in a [[growth vat]] - this removes the Natural [[meditation|meditation focus]], if it was present. Their adult backstory will be set to Tribe Member or Colonist, respectively.

== Stats ==
Children and teens have various penalties to speed and effectiveness. Specifically, they have a multiplier to the following stats: [[Move Speed]], [[Aiming Time]] & [[Melee Hit Chance]] (thus, {{DPS}}), [[Arrest Success Chance]], [[Global Work Speed]], [[Market Value]], and [[Body Size]]. Each trait is affected differently by age: Global Work Speed rises steadily until adulthood, whereas Move Speed changes in jolts by life stage.

Children also have penalties to melee damage and [[Shooting Accuracy]],the stat factor [[Shooting Accuracy Multiplier (Child)|ShootingAccuracyChildFactor]] limits the maximum ShootingAccuracy of child. the meleeDamageFactor(not the stat factor of [[Melee Damage Factor|MeleeDamageFactor]]) defined in LifeStage limits the Melee Damage for Children and teens,The rates are as follows: children(3–8):0.7, preteens(9–12):0.725, teens(13–17):0.75, adult(18-): 1 . the Melee Damage will be multiplied by the meleeDamageFactor.

Note. The melee hit chance multiplier is applied not to the hit chance itself, but to the bonuses and penalties imposed on it. That is, a 3-year-old child will have ~ 50% +-5% chance of hitting both having the maximum skill level + Go-juice, and having severe traumas that reduce work and vision to 0%.

Stats that ''don't'' differ for teenagers include food consumption, Maximum/Minimum comfortable temperatures, and Filth rate. Note that teenagers also have a 1.25 multiplier on maximum nutrition, which offsets the 0.8 multiplier from their reduced body size, resulting in the same nutrition capacity as an adult.

Increasing the growth rate lowers a pawn's chronological age at any given biological age. For example, at 200% aging, it takes ~10 years to reach age 18, and at 400% aging, it takes ~5.4 years (assuming 100% adult aging speed).

A pawn with the [[ageless]] [[gene]] will linearly age slower after 13, before coming to a complete halt at 18.5. With this gene and the default rates, a pawn will take 429 days (7.15 years) between ages 13 and ''17'', then a further 362 days (~6 years) to reach age 18. A growth vat can be used to decrease this time, if so desired.

The fastest a pawn can age is in a growth vat from birth with the '''Growth vats: Essential''' [[Precepts#Growth vats|precept]]{{IdeologyIcon}}, where they reach adulthood in only ~40.5 days, after which they will age according to the set aging rate. Note that these values won't be accurate if a pawn has the ageless gene, spends time both in and out of growth vats, or the aging rates are altered in the storyteller settings mid-gameplay.

== Wearable clothing ==
Being much smaller than adults, children can only wear a limited selection of clothing, mostly consisting of headwear:

<div class="ul-column-width-200">
{{#ask: [[Lifestage::~Child*]]
| format = template
| template = Icon List
| link = none
| sort = From DLC
}}
</div>

== Ideoligion ==
{{Ideology|section=1}}
{{Stub|section=1|reason=Worked example}}
Babies have no [[ideoligion]] of their own, however when a baby becomes a child at age 3, an ideoligion is assigned to the child based on a weighted random selection.

These weights are assigned to the ideoligions of the pawns that interact with the baby. For the purposes of this calculation, this is specifically:
* {{+|0.5}} for any social interaction.
* {{+|1.0}} for carrying the baby for one hour.
* {{+|1.0}} for breastfeeding the baby for one hour.
* {{+|1.0}} for feeding the baby [[baby food]] for one hour.
These interactions are remembered forever until the baby transitions into a child.

As with all weighted selections, the more that pawns from a given ideoligion interact with the baby, the more likely the baby is to choose that ideoligion, however ultimately there is always a chance selects any ideoligion to which it was exposed.

== Analysis ==
When raised naturally and with lots of Learning time, children can very easily become powerful colonists. With the ability to choose from up to 6 [[traits]] per growth moment, the likelihood for at least one "great" trait, like [[Jogger]], [[Industrious]], or [[Quick sleeper]], per growth moment is significant. A child is very likely to have multiple ''good'' traits by the time they become a teen. Passion choice is also excellent - burning passions in any desired field are quite common. Needless to say, it'd be very rare for a randomly generated adult to match a colony raised child.

Child rearing mainly comes at a cost of time, with slightly more than 2.5 years spent in the child stage on default Child Aging Rate settings. Children do not actually require much adult supervision to grow and learn. Set an [[allowed area]] so that they won't wander too far from your base, and children will develop to become a fairly powerful colonist. However, to reach the highest growth level of 8, you need to ensure that their average learning need is at least 90% (even while sleeping). As children will not start learning unless their learning need is already below 90%, this requires more careful management, especially for children under the age of 7.

To fulfill their learning, you may need to:
* Build a [[comms console]], a [[school desk]] with 3 [[blackboard]]s, allow the child outside, and get at least 1 [[book]] to cover all possible Learning types. In practice, you can skip out on 1-2 types, and still reach growth level 8, just hope that the types you skip don't come up together at the same time.
* Constantly monitor your child's learning need and their desired activities. Sometimes they will not start learning even though their need has dropped below 90%, you'll need to diagnose the problem before it cause them to miss the growth target. If you notice a child is behind in learning progress, wait until reading appears as one of their learning needs. As reading can be forced manually, you can keep the child’s learning at 100% (with smaller dips for eating and sleeping) by forcing reading even when learning is above the 90% threshold.
* When the child is sleeping and their learning need drop below 90%, wake them up so that they can bring it up to 100% before sleeping again.
* Try not to interrupt the child before their learning need reach 100%, because they won't start learning again for a while.
* Work watching: children age 3-7 can only do work watching on social tasks, so consider ordering an adult to attempt to recruit a prisoner when a child need to work-watch.
* Lesson taking: children will not start learning unless there is an awake adult who is capable of teaching. Wake you teacher up when the child need to take lessons.
* Skydreaming: sometimes you need to draft the child and move them outside for them to start this activity

Older children that join your colony will be comparatively worse off.

===Baby stage===
As opposed to the proper child stage, the [[baby]] stage, which lasts for 45 days (3/4ths of a year), requires a notably higher amount of colonist labor. Feeding babies takes a surprisingly long time, especially if breastfed. The base duration of feeding a baby from empty is {{ticks/gametime/hours|5000}}, and babies need to be fed roughly twice a day. Between this and caring for her own needs, a mother tasked with caring for her baby can spend over half her waking hours, every day, for those 45 days. On the plus side, feeding and playing with babies can be done by children as young as age 3.

[[Growth vat]]s can be used to skip the baby stage, at the cost of nutrition and a slight mood penalty to parents. Babies don't learn, so this comes at no cost to a child's development.

=== Vats ===
{{Main|Growth vat}}
[[Growth vat]]s can turn children into working machines. It still takes a long time to grow a person - 9 days for the embryo to be born in vat, another 39 days to reach age 13, and then a further 15 days to reach 18 (if desired), for a total of 63 days from embryo to 18 (~ 52.6 days with a pro-vat [[ideoligion]]{{IdeologyIcon}}). In the meantime, the vat consumes a lot of food. Growing an embryo requires a total of 54 [[nutrition]] - 60 simple meals, or 4 colonists of food for 9 days - while a pregnant mother would consume an extra 30% nutrition for 18 days. Growing the child thereafter requires 2 colonist's of nutrition per day. Unlike with most colonists, you can use undesirable foods like [[human meat]] and [[kibble]] with no penalty.

Vatgrown pawns have 0 passions, barely any skills, and 3 random traits. Despite this, extra bodies can always be useful for tasks like Hauling and Cleaning, or fighting in general. While any [[Events#Wanderer joins|wanderer]] or captured [[raider]] is likely to be better, all three [[storyteller]]s have a population intent. As you have more people, it becomes harder to recruit more colonists. Children ignore this mechanic entirely. Therefore, growing children becomes more viable for larger colonies.

[[Gene]] modding can make vatgrown children much more powerful. For example, the [[Great shooting]] gene provides 8 Shooting skill, added on top of the pawn's "true" skill level, and a passion. If planted immediately after birth, the extra passion will nearly triple the Shooting skill bonuses from the vat. This can provide late-game colonies with a functionally infinite supply of soldiers, ignoring the game's natural population curve, and limited only by food production (and possibly lag).

Note that using vats to speed up the baby stage (0-3) and teen stage (13-18) does not penalize the pawn in any way. Babies don't learn or work, and speeding up this phase comes mostly at the cost of [[mood]]. Speeding up a teen to adulthood removes their work speed and body size penalties, though they could've done work in the meantime. However, teens in growth vats do not apply a mood penalty to their parents, as they are not "kids" anymore. Also note that unlike with [[cryptosleep]], colonists in vats have absolutely no penalty applied to them when they exit the vat. If you need them for an emergency (such as a dangerous incoming raid), they can be removed from the vat at a moment's notice.

The '''anima tree''' is a tree added by the [[Royalty DLC]]. It acts as a meditation focus and source of [[psylink]]s for pawns with the [[Psyfocus#Natural|Natural]] focus type, but is sensitive to artifical structures around it.

== Growth ==
One anima tree spawns on most [[World generation#Landing site|landing site]] maps. On larger map sizes, up to two may spawn. The Extreme Desert, Ice Sheet, Sea Ice, and Glacial Plains [[biome]]s are too inhospitable for anima trees to spawn. [[Glowforest]]s{{OdysseyIcon}} will not have an Anima Tree at first, but an Anima Tree will eventually spawn.

Anima trees are immune to [[fire]], [[toxic fallout]], can survive up to {{Temperature|-50}}, and will survive in the [[sun blocker|absence of light]]. [[Thrumbo]]s will not eat anima trees, but [[alphabeaver]]s can. It is also susceptible to both [[defoliator]]s and [[defoliator ship]]s. [[Anima grass]] is vulnerable to fire, and will rot if left without light, but will not be eaten by grazing animals. Note that while the anima tree has no lifespan, any anima grass only lives for {{Q|Anima grass|Lifespan}} [[time|days]].

=== Regrowth ===
Destruction of the anima tree causes the {{Thought|desc=Such a pain in my head when the tree died. And it keeps echoing...|label=Anima scream|value=-6|stack=3|duration=5}}. The mood effect scales with [[Psychic Sensitivity]].

After roughly 30 days, it will grow back in a [[Events#Anima tree sprout|random event]] at a random location away from artificial buildings. This can be used to move a tree from an inopportune location at the cost of mood.

|}

== Meditation mechanics ==
Meditating at an anima tree requires a [[Psyfocus#Natural|Natural]] [[meditation focus]], which a pawn can only gain from their childhood [[background]]. Only Tribal backstories can have the focus type, and several of them do not provide it. Pawns do not need to have psylink levels to meditate. [[Schedule]] meditation and place a [[meditation spot]] so that your colonists will actively meditate near the tree.

Meditation at the tree serves three purposes; firstly, it grows anima grass for the granting of psylink. Secondly, it acts as the second best meditation focus, after [[animus stone]]s, for Natural meditation, increasing the rate at which psycasters meditating to the tree gain psyfocus. Thirdly, it is a form of solitary recreation which grants joy at the default rate (0.0144% per tick, calculated before recreation tolerance).

=== Anima grass ===
Meditating near an anima tree creates '''anima grass''' around the base of the tree. Once at least 20 grass has been grown, a level of psylink can be granted to a pawn with the Natural meditation focus type.

Anima grass is created proportional to the pawn-hours spent meditating to it. Multiple pawns can meditate at the same time to speed up the spawning of the anima grass. At 100% effectiveness, one pawn-hour of meditation grows approximately 16% of one anima grass patch. After 12 pawn-hours of cumulative meditation time, grass growth slows by 50% to 8% of growth per pawn-hour. After 24 pawn-hours of meditation time, it slows to 25%, or 4% of growth per pawn-hour. Finally, it drops to 15% of the normal growth rate after 48 pawn-hours of meditation time. This counts all pawns that have meditated during a 24 hour period. This rate is also affected by the [[#Artificial buildings|artificial buildings]] surrounding the tree, up to a -30% of the growth. A full -30% penalty does not stop growth after 24 pawn-hours, suggesting that factor is applied multiplicatively. If there are multiple trees on a map, each will have its own anima grass and threshold, allowing more grass to be grown before hitting diminishing returns.

The pawn must have Natural meditation available in order to grow anima grass. However, the health, psylink level, and [[psychic sensitivity]] of the meditating pawns has no effect on the amount of grass generated, even if they are psychically deaf.

=== Linking ritual ===
The linking ritual takes approximately 5 hours and requires 20 anima grass.

This ritual can grant a psylink to a pawn without one or improve the level of an existing psylink; even one granted using a [[psylink neuroformer]] or through an Empire [[Titles|bestowing ceremony]]. This only works on pawns with the Natural meditation type and a non-zero [[psychic sensitivity]]. [[Children]]{{BiotechIcon}} cannot link to the anima tree but can participate in the ritual otherwise. Once the ritual is complete, 20 anima grass will die, and some amount of anima grass will be restored based on the number of participants.

|}

Any remaining or regrown grass can then be used for future linking rituals, however note that the grass has a limited lifespan of {{Q|Anima grass|Lifespan}} [[time|days]].

=== Meditation focus ===
Psycasters regain psyfocus at a base rate of {{+|50%}} psyfocus per day spent meditating. Foci in range of the psycaster's [[meditation spot]] and of a focus type they share increase this rate additively. Anima trees have a base meditation focus strength of {{+|28%}} psyfocus per day. Each [[animus stone]] within 9.9 tiles increases the meditation effectiveness by {{+|2%}}, while each [[small nature shrine|small]] or [[large nature shrine]] within 9.9 tiles increases it by {{+|1%}}. Up to four buildings can affect the tree, for a maximum bonus of {{+|8%}} from 4 animus stones. This rate is also affected by the [[#Artificial buildings|artificial buildings]] surrounding the tree.

However, the anima tree will still grow grass with 5 animus stones in the vicinity. With five animus stones, a psycaster will gain psyfocus at a rate of 92% per day without interference from buildings while also being able to grow anima grass. Similarly, in practice an anima tree with 4 animus stones will recharge psyfocus at a rate of 90% per day, {{+|40%}}, assuming all objects are within range of each other. They will technically be meditating at the animus stone and not the anima tree. The anima tree is ignored for psyfocus gain but not for anima grass growing.

The maximum meditation focus strength is thus {{+|42%}} for an anima tree with no artificial buildings within 34.9 tiles and surrounded by five animus stones.

=== Artificial buildings ===
Building an artificial building within a 34.9 tile build radius will reduce the anima grass growth rate, and meditation strength within a 27.9 tile radius (the 27.9 tile radius is displayed in red while the anima tree is selected). The reduction is set by the following curve:

<div><li style="display: inline-table;">
{| {{STDT| c_07 text-center}}
! Artificial items<br>in range !! Strength<br>offset !! Graph
|-
| 0 || '''0%'''

}}
|-
| 5 || {{--| 8%}}
|-
| 10 || {{--|15%}}
|-
| 50 || {{--|30%}}
|}
</li></div>

Keep in mind that a pawn will preferentially meditate at the highest rate natural building, so two animus stones next to an anima tree will give +4% (+28%-28%+2%+2%) but two animus stones on their own will only give +2% (+34%-34%+2%). Without the artificial building penalty, both situations would be equivalent +36% (+34%+2%) as a pawn would always meditate at the animus stone and the anima tree would be ignored, though grass still grows.

The following buildings are not considered artificial for this purpose:
<div class="ul-column-width-200">
* [[Snowman]]
* [[Torch lamp]]
* [[Horseshoe pin]]
* [[Hoopstone ring]]
* [[Grave]]
* [[Campfire]]
* [[Small nature shrine]] {{RoyaltyIcon}}
* [[Large nature shrine]] {{RoyaltyIcon}}
* [[Animus stone]] {{RoyaltyIcon}}
* [[Shard beacon]] {{AnomalyIcon}}
* [[Fleshmass heart]] {{AnomalyIcon}} and all related structures
* All [[spot]]s
* All [[floor]]ing
* All types of smoothed stone walls</div>

[[Ruins]] also do not have any penalty '''so long as the ruins remain unclaimed;''' claiming the ruins will cause them to apply the usual penalty. Despite their similarity to other exempted objects, [[monument marker]]s {{RoyaltyIcon}} are considered artificial.

Selecting the tree displays two circles around the tree:
* The smaller (9.9 tiles radius), green circle is the range at which animus stones and nature shrines can link to the tree.
* The larger (27.9 tiles radius), red circle indicates where artificial structures will disrupt the tree. The "Build radius warning" option, turned on by default, will create a red line whenever you try to place a building within the radius. (Note: buildings in the larger 34.9 tile radius will not cause the warning, but will still impact the grass growth rate).

== Analysis ==
The anima tree is an infinitely grindable source of psycast levels, making it a very powerful tool for Tribal starts or if you recruit tribal pawns that are good psycaster candidates. Compared to any other source of psylink, the anima tree is available at the start of the game, has a short recharge time, and has no resource cost.
*Royal [[title]]s can be farmed with sufficient [[prisoner]]s and/or [[gold]], but this costs resources, and the desired room/food also costs resources and boosts [[wealth]]. Late game colonies could sufficiently farm honor, but early game colonies won't.
*The [[psylink neuroformer]] item is only offered every 45 days at minimum.
*The [[Blindsight]]{{IdeologyIcon}} blinding ritual can be farmed for psylink levels by installing [[bionic eye]]s, but this requires the blindsight meme and potentially multiple bionic eyes per psycast level.

The downside is the anima tree's random placement that can't be manually moved, which can cause long travel times and thus pose some risk to colonist safety. It is possible to build near the anima tree at the cost of the artificial building penalty (although if it is near at the edge of the map, that is a risk of its own).

=== Buildings ===
There are two philosophies for building near the anima tree:
* Option 1: Leaving the anima tree clear from artificial structures. You can still install attractive [[floor]]s and plant flowers (where grass won't spawn) to keep the area [[beauty|beautiful]] and meditators happy without affecting the tree. A bed and dining room just outside of the radius can help lower travel time. This method is ideal if you dedicate a colonist's entire workday to meditation. Psycasters can gain psyfocus at the maximum rate of 92% per day, or 3.83% per hour.

* Option 2: Ignoring the artificial penalty entirely. Create your entire base right next to the anima tree, and surround the tree with [[wall]]s. This makes the travel time much shorter, and keeps your pawns safer against raids during meditation. In [[biome]]s where the [[Events#Beavers!|Beavers!]] event can happen (arid shrubland, tundra), it also keeps the ''tree'' safe.
** Make sure not to build a [[roof]] or floor over the tree, or where grass can spawn. Use the [[remove roof area]] tool in the Zoning tab so that your builders don't cut down the tree.
** While building close to the tree impacts the rate at which you gain psyfocus, the psyfocus gain provided by the tree is an "offset" on top of a pawn's base psyfocus gain of 50%/day. With 50 buildable items in the vicinity, the anima tree will not provide any bonus to meditation but any items providing bonuses will still provide the benefit. The lowest possible psyfocus gain is 50% per day while the maximum amount lost is -34% per day, if a single animus stone is used. A pawn will actually meditate at the animus stone over the anima tree but anima trees do not provide a bonus to animus stones, 2 animus stones are needed to see any bonus beyond 50% psyfocus gain per day. This will generate psyfocus at a rate of 2.08% per hour. With 5 animus stones, the rate will be 58% per day, or 2.42% per hour.
In either case, a ring of flooring around the tree and grass spawning area can be useful to prevent [[fire|wildfires]] destroying the grass.

Psycasters lose psyfocus at a maximum rate of 7.5% per day. The least a psycaster will need to meditate using option 1 is for 1.95 hours with 5 animus stones. The least a psycaster will need to meditate using option 2 with 5 animus stones is for 3.10 hours. During that additional 1.15 hours or 2875 ticks, a pawn with default movement speed of 4.6 cells per second, or 0.077 cells per tick, could walk 221 cells. Since a return trip is required, anima trees outside of 110 cells from the likely point of travel experience a time penalty greater or equal than the penalty caused by artificial buildings.

If only using small nature shrines (as 5 animus stones are expensive and difficult to acquire, especially at the stage of game when anima grass is most desired) the times to meditate become 3.42%/hr vs. 2.17%/hr (note that the addition of shrines allows the full -30% penalty). During that additional 1.26 hours or 3150 ticks, a pawn with default movement speed of 4.6 cells per second, or 0.077 cells per tick, could walk 242 cells. Since a return trip is required, anima trees outside of 121 cells from the likely point of travel experience a time penalty greater or equal than the penalty caused by artificial buildings.

On the default map size of 250x250, the furthest point from the center is 125 to 176 cells depending on direction. However, trees on the far edge of the map should probably be chopped in hopes of a better location as those locations will likely not be built around anyways. An anima tree in a central location should left building free, with likely starting locations such as dining halls and bedrooms placed within 86 cells of the edge of the build radius warning.

With longer meditation times, the travel time becomes less significant but the building penalty still applies to anima grass growth. It becomes difficult to see any advantage to a tree being enclosed by buildings for the purposes of creating psycasters or using high cost psycasts. It is also easier to make a pawn move faster than it is to place an anima tree for a slow pawn. Colonist risk far from safety is still a factor.

=== Pawns ===
For maximum growth, [[schedule]] one or more colonists to just meditation, only stopping to eat or sleep. This also reduces travel time, useful if you have built away from the anima tree. Meditating will provide some [[recreation]]; while they will rapidly become [[Recreation#Recreation tolerance|bored]] with it, it will still keep the bar full if done all day. If a ruin or natural wall is within 6 tiles, consider [[roof]]ing over their meditation spot to keep them out of the [[weather|rain]] and [[toxic fallout]].

If the anima tree is very nearby to the colony, then you can also schedule meditation for all tribal colonists in place of recreation. Meditation does fill up the recreation meter, even if colonists will get bored of it. If a large portion of colonists are set to meditation, then you will quickly hit the soft limit for grass growth.

While the grass does not grow faster when meditated at by a psycaster, they are still ideal choices. The psyfocus gain from meditation not only replaces their need to meditate elsewhere; it also all but guarantees that they will be consistently at 100% psyfocus. This especially synergizes with high-psyfocus-cost, non-combat psycasts such as [[word of trust]] or [[word of inspiration]], and is valuable for keeping casters combat-ready as well.

Temporary pawns from quests with a natural meditation focus can meditate at the tree even if they are incapable of working.

Prisoners with a psylink will meditate a few hours per day to maintain their psyfocus. Building a prison barrack around the tree with natural meditation focus psycaster prisoners will slowly generate anima grass.

'''Creepjoiners'''<ref>The term ''creepjoiner'' is taken from the game's code, and is not used in-game.</ref> are a phenomenon added by the [[Anomaly DLC]]. They are humans who will randomly arrive at your colony offering to join, typically providing great benefits but often concealing downsides that can range from minor annoyances to debilitatingly dangerous. Creepjoiners can be encountered even before activating the [[void monolith]].

== Summary ==

Creepjoiners always request to join the colony. They will appear on the edge of the map and make their way to a nearby location - similar to a [[trader]] - where they will linger and wait for someone to be sent to talk to them. Upon doing so, three options are presented: to accept the request to join, to arrest the creepjoiner, or to refuse the creepjoiner's request.

If rejected or if ignored for {{ticks/gametime/days|60000}}, creepjoiners have an equal chance to either depart peacefully or to immediately become hostile and attack.

Every creepjoiner has an upside and a possible downside. Potential options for each of these can found in the [[#Benefits|Benefits]] and [[#Drawbacks|Drawbacks]] sections.

All creepjoiners are initially [[unwaveringly loyal]]. This condition is permanently removed if they are allowed to join the colony. If arrested before joining, such as by choosing the "''Send <PAWN NAME> to capture <CREEPJOINER NAME>''" option when first speaking to them, they can only be recruited by removing their unwavering status using the [[brainwipe]] [[ritual]]. Creepjoiners can also be [[Slavery|enslaved]], {{IdeologyIcon}} although their extremely high will of 80-90 makes this very tedious.

Creepjoiners can be studied for Advanced [[Research#Anomaly|void research]] if taken prisoner. They give 2 Advanced research with a cooldown of 2 days. The creepjoiner must be able to walk to be studied.

Creepjoiners cannot be duplicated by the [[corrupted obelisk]].

Creepjoiners are unable to romance ordinary pawns, but they can romance other creepjoiners or be forced into relationships by pawns with the [[psychic bonding]] gene. {{BiotechIcon}} Creepjoiners can become [[pregnant]] {{BiotechIcon}}, but their children will be normal humans and not inherit any of the unique mechanics of creepjoiners.

[[File:Marriage_Creepjoiners.png|thumb|A marriage ceremony between two creepjoiners. Other pawns from the colony are participating.]]

=== Occurrence ===

Creepjoiners start appearing randomly after 10 days from game start. Reoccurrences are subject to a 60-day cooldown. There are no other requirements, but until the Monolith reaches level 2, the metalhorror variant is disabled, making creepjoiners slightly rarer.

==== Farming ====

It is possible to reliably spawn creepjoiners via [[void provocation]]. The monolith must be kept at level 2, and [[metalhorror]] must be left undiscovered (keeping colony population at 3 or less will prevent it from appearing naturally). In this state, void provocation can spawn a metalhorror-infected creepjoiner, and will do so every time (subject to the 60-day creepjoiner cooldown) after all other advanced entities are discovered. This basically guarantees one creepjoiner per year, with the added benefit of blocking non-metalhorror downsides, including the permanently detrimental ones.

Of course, once such a creepjoiner is accepted into the colony, a metalhorror encounter is inevitable – which means this method can be used to recruit only one creepjoiner per playthrough (or one batch of creepjoiners, but they would need to be gathered over many years into a cryptosleep stash then recruited all at once). Therefore, it's best used as a mechanism to reroll creepjoiners until a highly desirable one appears. Bad creepjoiners can be reliably disposed of without revealing their metalhorrors by simply allowing them to join and immediately banishing – this can even be done with the game paused.

Naturally-occurring creepjoiners and void provocation-summoned creepjoiners are on separate 60-day cooldowns, so a colony actively farming them can expect to average some 1.5 creepjoiners per year.{{Check Tag|Code?|In actual gameplay on 1.6.4566, it clearly works like this, but from looking at the code, it's not clear why it would, could this be a bug?}}

=== Types ===

Each creepjoiner type comes with preset equipment, traits, and possible [[#Benefit|benefits]]. A brief summary of each possible type's notable properties is provided here:

* '''Leathery stranger:''' No unique effects.
* '''Dark scholar:''' Has the [[Psychopath]] trait, 14-20 in the [[Intellectual]] skill, and several surgical scars.
* '''Deal maker:''' Has the [[Beautiful]] trait and 14-20 in the [[Shooting]] and [[Social]] skills.
* '''Drifter:''' No unique effects.
* '''Blind healer:''' Always spawns missing both eyes, which can be replaced with full functionality by the [[Ailments#Healing method table|usual methods]]. Guaranteed to have the ''unnatural healing'' benefit.
* '''Timeless one:''' Always between 13 and 16 years old. Not to be confused with [[Ageless]].{{BiotechIcon}}
* '''Cult escapee:''' Usually has many surgical scars and/or removed body parts. 50% chance to spawn with a [[flesh tentacle]] on either arm.
* '''Lone genius:''' Has the [[Too smart]] and [[Abrasive]] traits, as well as 13-18 in the [[Intellectual]] skill.

=== Benefits ===

Every creepjoiner has a single benefit, chosen at random. Most creepjoiner types have a specific list of possible benefits that they are restricted to; for more information, consult the [[#Pawn Kinds|Pawn Kinds]] table at the bottom of the page.

* '''Perfect human:''' Has the [[Industrious]] trait and 14 to 18 in all [[skills]]. Also has the unique [[Perfect memory]] trait, which entirely disables skill decay.
* '''Occultist:''' Has the unique [[Occultist]] trait.
* '''Unnatural healing:''' Has the ''unnatural healing'' ability (see below).
** This benefit has a weight of 0.5 (compared to the weight of 1 for every other benefit), making it less likely to be chosen on its own.
* '''Shambler overlord:''' Has the ''release deadlife dust'' ability.
* '''Fleshcrafter:''' Has the ''shape flesh'' ability.
* '''Alchemist:''' Has the ''transmute steel'' ability.
* '''Joybringer:''' Has the unique [[Joyous]] trait, which grants {{good|+20}} opinion from all other pawns and a {{Thought|desc=Wherever I go, I can feel the joyous one in the back of my mind. It makes me feel good. Very good.|label=Joyous presence|value=+3|stack=1}} to all colonists on the map.
* '''Death refusal:''' Starts with four uses of [[death refusal]].
* '''Body mastery:''' Has the unique [[Body mastery]] trait, which completely removes the pawn's need for [[food]], [[sleep]], and [[comfort]].
* '''Psychic butcher:''' Has the ''psychic slaughter'' ability.

=== Drawbacks ===

Creepjoiners typically have one downside applied to them upon spawning. These downsides are almost always hidden from the player, and only become revealed when their effects first manifest. A list of possible drawbacks includes:

* Nothing.
* '''Desertion:''' After 9-30 days in the colony, the creepjoiner will suddenly depart. They will immediately attempt to exit the map, abandoning any work they were doing in the process.
** This drawback has a weight of 3 (compared to the weight of 1 for every other downside), making it more likely to be chosen than any other drawback.
** [[Prisoner|Imprisoned]] or [[Slave|enslaved]] {{IdeologyIcon}} creepjoiners will wait until they are freed to desert.
** A creepjoiner captured while deserting and subsequently recruited or enslaved {{IdeologyIcon}} will not attempt to desert again.
** Creepjoiners can desert even when they are currently [[downed]].
'' '''<PAWN NAME> departure:''' <PAWN NAME> thanks you for your hospitality, but says that it is time for <PAWN'S PRONOUN> to move on. ''
* '''Aggressive:''' After 9-30 days in the colony, the creepjoiner suddenly becomes hostile and attacks.
* '''Metalhorror:''' The creepjoiner is secretly infected with a [[metalhorror]].
** Creepjoiners with this downside will always become hostile if not accepted by the colony.
** This downside does not appear under normal conditions. Instead, creepjoiners with a metalhorror can only appear as part of a unique incident that appears identical to a regular arrival. It is naturally 5% as likely to appear as a regular creepjoiner, but is one possible outcome of [[void provocation]].
** Outside of the ''ambient horror'' [[AI_Storytellers#Anomaly|storyteller option]], the [[monolith]] must be at least level 2 for this downside to occur.
* '''Crumbling mind:''' After 1-3 days, the creepjoiner is revealed to be suffering from a [[crumbling mind]].
** Can be diagnosed early with a surgical inspection: ''<CREEPJOINER NAME> is showing early signs of a severe condition which will soon cause severe mental degradation. <PAWN NAME> can't yet tell exactly what is causing this, but they will become very ill within the next few days.''
* '''Void fascination:''' Guaranteed to have the unique [[Void fascination]] trait. Immediately apparent.[[File:AgonyPulseDeath.png|right|450px]]
* '''Psychic agony:''' The creepjoiner periodically emits an [[Hediffs/Anomaly/Global/Misc/Agony_pulse|agony pulse]], affecting all pawns within 14.9 tiles ''including the creepjoiner themselves.'' This happens once every 30 days on average, with a minimum time of 5 days between each occurrence.
** Can be diagnosed early with a surgical inspection: "''<PAWN NAME> detected a faint but painful psychic presence emanating from <CREEPJOINER NAME> but failed to understand what was causing it.''"
** Affected targets receive {{bad|+100%}} [[pain]], which is enough to instantly down all pawns without a source of pain reduction. After {{ticks|600}} to {{ticks|900}}, this is reduced to a milder {{bad|+25%}} pain that lasts between {{ticks/gametime/days|120000}} and {{ticks/gametime/days|240000}}.
** At 100% pain, [[consciousness]] is reduced by 40%, meaning that Agony Pulses can kill pawns when combined with consciousness reductions from other sources.
** The agony pulse is ''not'' modulated by [[psychic sensitivity]]; even [[psychically deaf]] pawns will suffer its effects.
* '''Organ decay:''' After 3-5 days, the creepjoiner will reveal that they are suffering from [[organ decay]] in 3-5 internal organs. This uses a unique variant of organ decay that progresses three times faster than normal, allowing only 10-20 days to treat each instance.
** Can be diagnosed early with a surgical inspection: ''"<CREEPJOINER NAME> is showing early signs of a severe condition which will cause their organs to rapidly deteriorate. <PAWN NAME> can't yet tell exactly what is causing this, but <CREEPJOINER NAME> will become very ill within the next few days."''
* '''Disturbing:''' Guaranteed to have the unique [[Disturbing]] trait. Immediately apparent.

=== Hostility ===

Regardless of whether they are recruited, all creepjoiners will immediately become hostile the first time they receive friendly fire damage or a colonist attempts to [[slavery|enslave]] {{IdeologyIcon}} them once their will reaches 0. This can only happen once for each creepjoiner, but will never expire, so there is always the possibility of the creepjoiner turning hostile until it actually happens.

Each creepjoiner has a special effect, chosen randomly, that will activate when they become hostile:

* '''Basic assault:''' No special effects.
** It has weight of 3, meaning it's 3 times more likely to be chosen than other hostility responses.
* '''Sightstealer attack:''' The creepjoiner will scream and summon [[sightstealer]]s to attack the colony.
'' '''<PAWN NAME>'s howl:''' <PAWN NAME> has let out a twisted half-human scream. In the distance, you can hear other screams answering the call. They are coming... ''

These effects also trigger if the creepjoiner dies by any means.

An easy way to resolve a creepjoiner's hostility is to anaesthetize them then punch them while they're out. They will become hostile, but remain incapacitated, enabling safe capture and re-recruitment. Of course, this will still destroy the creepjoiner if fleshbeast emergence was randomly picked as their way of retaliating.

== Analysis ==

The abilities possessed by creepjoiners range from modestly useful to potentially colony-changing. Evaluate the possible tradeoffs above, and be prepared to deal with sudden turncoat behavior. Carefully inspect the pawn's entire Bio and Health tab before recruiting them. One must decide whether the potential risks a creepjoiner brings are worth it, but also weigh the downsides of ''not'' recruiting them (such as an aggressive response).

Performing a [[surgical inspection]] can reveal some potential downsides early - making it a useful habit to practice with new creepjoiners - but not all of them. Vigilance is still necessary even when the inspection finds nothing.

A creepjoiner's time-based downsides (such as ''organ decay'' or ''crumbling mind'') can be halted by placing them inside a [[cryptosleep casket]] until treatment is available. This will naturally disable the creepjoiner until they're removed from the casket, so prepare to survive without their skills and abilities for what could potentially be an extended period of time.

If a creepjoiner's downsides cannot immediately be determined then it may be useful to keep them physically isolated. [[Allowed area]]s and [[schedule|scheduling]] can be used to mitigate their proximity to other colonists until their downside is revealed for what it is.

Before you have ruled out the possibility of desertion, you may want to consider whether or not it is worth giving them expensive or rare items (such as high-quality armor, weapons, or bionic parts). While this equipment can be recovered if the deserting creepjoiner is arrested, there is always the risk that your colonists will not be able to catch them and you will consequently lose the equipment. To catch a deserting creepjoiner, it is advised to attack them to slow them down, and then capture them. Successfully arresting the deserter and then recruiting them again will make them join the colony permanently, without wanting to desert again.

The potential for [[#Hostility|fleshbeast emergence]] should also be ruled out before equipping a creepjoiner with powerful gear or [[genes]] {{BiotechIcon}}. Because it destroys the body outright, any equipped gear or installed parts are destroyed with no chance for recovery. This ignores (and negates!) [[death refusal]] and [[deathless]] {{BiotechIcon}}, so it is important to either rule out the possibility of fleshbeast emergence before applying these powerful effects, or to simply accept the risk that they may be wasted.

Mental break

2026-01-27T20:35:28Z

MortalSmurph: Run Wild is possible at 1 colonist.

{{Stub|reason=1) What are the actual MTBs for breaks? how is frequency calculated? 2) Which breaks are "aggressive" or "violent" and thus affected by [[Dead calm]]/[[Hyper-aggressive]]/[[Aggressive]] - information should be linked to or replicated on [[Genes]] 3) Needs information on non-mood based breaks - e.g. drugs, psychic breakdown, ailments etc. In game times - Days easier to parse than 10000s of ticks. Also needs Biotech mental breaks e.g. Fleeing fire.}}{{About|the mental conditions experienced by unhappy pawn|breaking objects|Max Hit Points}}
{{TOCright}}
A '''mental break''' is a pawn event that may occur when a pawns's '''mood''' drops below the '''mental break threshold'''. Majority types of mental break cause a '''mental state''', during which the pawn will become uncontrollable and shirk work tasks for a short while, or even worse, they will attempt to sabotage the colony. A breaking colonist may be interrupted by arresting or downing them. A few types of mental break, like catatonic breakdown or crisis of belief{{IdeologyIcon}}, do not cause mental state.

There are three levels of severity for mental break events: '''minor, major,''' and '''extreme'''. Each severity level has a different pool of possible events that may occur at different frequencies. Minor events include hiding in the pawn's room for a day, extreme events include murder.

Colonists, visitors, enemies, tamed, and wild animals all have types of mental breaks.

Some mental states may be induced by the player in battle, via [[psycast]]s {{RoyaltyIcon}} or weapons like the [[psychic shock lance]] or [[psychic insanity lance]].

== Mechanics ==
=== Mood ===
[[Mood]] is a visual indicator of how likely your pawn is to have a mental break. It is lowered by negative [[thoughts]] about the pawn's environment and raised by positive thoughts. Mood is found in the [[Needs]] tab of the pawn Inspect pane.

The three mental break severity levels directly correspond to the low mood levels '''Stressed, On edge,''' and '''About to break,''' respectively. Mental break events and frequencies are different for each mood level.

Pawn mood is related to the sum of all the thoughts a pawn has, so minor penalties can quickly add up to large effects on a pawn's stability. Some mental breaks are unavoidable in even the finest, happiest colonies, such as '''Fire Starting Sprees''' by pyromaniac pawns.

=== Thresholds ===
{{Main|Mental Break Threshold}}
A specific pawn's mental break thresholds are affected by various personality [[traits]]. Traits may directly raise or lower mental break threshold, such as [[Steadfast]] or [[Nervous]] respectively. Some traits add permanent negative thoughts, like [[Pessimist]], or conditional negative thoughts, like [[Night owl]]. Multiple traits have an additive effect, but the minor break threshold is capped between 1% and 50%.

The major break threshold is 4/7 of the minor break threshold, while the extreme break threshold is 1/4 of that (1/7 of the minor break threshold). The base mental break threshold stat is 35%, which yields the following:
* Minor break threshold: 35%
* Major break threshold: 20%
* Extreme break threshold: 5%

=== Severity ===
There are three severity levels of mental break events, each with their own possible events and frequencies.

* Below their base mental break threshold, they will have a minor break in a mean time of 10 days.
* Below their major break threshold, they will have a major break in a mean time of 3 days.
* Below their extreme mental break threshold, their mood is ~5% and "About to break." they will have an extreme break in a mean time of 0.7 days.

=== During ===
[[File:Colonist icon while Binging on Psychite.png|frame|left|108px|Colonist icon while breaking]]
While a colonist is experiencing a mental break, their name is displayed <span style="color:limegreen;">'''in green'''</span> in the colonist bar (at the top of the game screen), and you have no direct control over them. They may enter restricted areas, consume restricted food or drugs, attack allies, or destroy objects. [[Arrest]] the misbehaving pawn to interrupt their mischievous actions. The broken colonist has a [[Arrest Success Chance|chance]] based on the arresting pawn's stats to either go berserk, or come quietly and be escorted to the nearest available prison bed - immediately ending their mental breakdown. However, arrest will downgrade their status as a member of your colony to a prisoner. Releasing them will return them to the colony, but replaces the catharsis bonus with a 'was imprisoned' negative thought (-8).

Another more extreme way of ending a mental break is by attacking the offending pawn, such as by beating the pawn with [[Weapons#Melee weapons|blunt-damage melee weapons]] until they are incapacitated by pain, or by inflicting [[brain shock]]. This is the only way to stop a berserk pawn. However, direct violence causes the victim to have a negative opinion of the colonists who beat him up, and you risk killing the pawn if he is already injured. It is ineffective if the pawn feels reduced pain, like those with the [[Painstopper]] implant or high on [[Go-juice]].

The [[word of serenity]] psycast{{RoyaltyIcon}} will instantly end any mental break by forcing the target into a 6 hour coma. The psyfocus cost depends on the level of the mental break the target is experiencing. This cannot be used on [[babies]]{{BiotechIcon}} or [[children]]{{BiotechIcon}}.

While having a break, at the top of the game screen, a colonist will be designated with a small "lightning bolt" icon over their image; yellow for non-aggressive breaks (such as food binge or daze), and red for aggressive ones (such as tantrum or berserk).

=== Aftermath ===
Once a pawn's mental break ends, they'll revert back to their usual schedule and work and may be drafted again. Their thoughts do not 'reset,' so negative thoughts may still be present. Pawns get the [[Thoughts#Catharsis|'catharsis']] thought, granting a +40 mood for the next 2.5 days. This will generally prevent a pawns from entering a spiral of mental breakdowns in all but the worst scenarios.

Colonists with the [[Tortured artist]] trait will have a constant mood debuff ({{--|8}}) but also have a chance (50%) to receive a creative inspiration after a mental break ends. Note that this does not include the [[#Fleeing fire|Fleeing fire]], [[#Run wild|Run wild]] and [[#Catatonic breakdown|Catatonic breakdown]] breaks.

Colonists may be considered '''guilty''' after particularly destructive breaks and may then be banished or executed with no, or reduced, consequences.

=== Anomalous breaks ===
{{Anomaly|section=1}}
Whenever a mental break happens, there's a chance that an anomalous break will happen over a normal one. If the game attempts to trigger anomalous mental break but is unable to, it will instead attempt to trigger a normal one. [[Creepjoiner|Creepjoiners]] will always trigger an anomalous break, unless none are possible. For every other pawn, the chance for Anomaly break to happen depends on the Anomaly stage.{{Check Tag|Clarification needed|Either links to a page re: what these refer to, or clarification here would be good}}

== Minor break ==

=== Food binge ===
[[File:FoodBinge.png|thumb|right|Food Binge]]

Causes the pawn to pig out on whatever food they can get their hands on.{{Check Tag|Details|Limits, preference, etc}}

This break can only occur when the map the pawn is currently on contains more than 10 human-edible nutrition in a [[stockpile zone]], however an already ongoing binge will not end if all the food is consumed or otherwise removed. Pawns with the [[Trait#Gourmand|Gourmand trait]] will experience this on average once every 50 days.

Pawns may ignore [[food policy]] restrictions during this binge, and will also disregard whether a food item has been disallowed. Pawns tend to prioritize eating higher-quality food regardless of such restrictions.{{Check Tag|Details|Requires more testing to be more specific}} If there is no food, or only low quality (raw (?)) food available in storage, pawns may travel large distances across the map to eat other food on the map, including [[insect jelly]] that is guarded by hostile [[insectoids]]. This can result in pawns being killed by insect hives.

A binge will end as soon as the affected pawn goes to bed, or after a certain amount of time has passed. Note that if [[wake-up]] is available, the pawn will take it during their break down, extending it to its maximum duration.

=== Sad wander ===
[[File:SadWander.png|thumb|right|Sad Wander]]

Causes the pawn to wander around aimlessly, eventually recovering on their own. Like the [[Mental break#Psychotic wandering (Daze)|Psychotic wandering (Daze)]] event, but shorter.

Wandering colonists can be [[prisoners|arrested]], which can be useful if they are in imminent danger.

=== Hide in room ===
[[File:HideInRoom.png|thumb|right|Hide in Room]]

Causes the pawn to wander about in their room, refusing to come out or satisfy their needs.

This break can only occur if the breaking pawn has a bedroom assigned to them.

This break is relatively short, and usually does not put the pawn in harm's way. At worst, the pawn may suffer from mild starvation or exhaustion.

=== Insulting spree ===
Causes the pawn insult nearby colonists at random, making moods worse for everyone affected.

Insults can lead to a social fight, which would then lead to the end of the break.

Requires at least two other pathable colonists to occur.

=== Targeted insulting spree ===
Causes the pawn to follow and repeatedly insult one other colonist in particular.

This can totally ruin the victim's mood with an up to {{Bad|-33}} mood penalty through 10 stacked insults, which can potentially trigger a mental break in the victim as well.

Insults can lead to a social fight, which would then lead to the end of the break.

=== Crying ===
{{Biotech|section=1}}
Babies may randomly cry while awake, being more likely to occur under 50% mood. This mental break is '''silent''' and can only be seen if the name is temporarily changed to green, emitting a random crying surrounding around itself.

Colonist near the baby will experience a negative mood effect "Baby crying" {{Bad|-4}} unless they are a "Psychopath". Any pawn's opinion of the crying baby will drop by {{Bad|-12}}.

Babies may randomly giggle while awake, being more likely to occur over 50% mood. This mental break is '''silent''' and can only be seen if the name is temporarily changed to green, emitting a rainbow of colorful drawing around itself.

Colonist near the baby will experience a positive mood effect "Baby giggling" {{Good|+4}} unless they are a "Psychopath". Any pawn's opinion of the giggling baby will increase by {{Good|+12}}.

=== Dark visions ===
{{Anomaly|section=1}}
Causes the pawn to mindlessly wander around, spouting utter nonsense about things that only they can see every 20-60 seconds, even if the pawn is incapable of talking. This can cause a negative mood effect of {{Bad|-2}} in nearby colonists, which can stack up to four times.

Upon recovery, the colonist will gain a {{Good|+30}} "Void catharsis"{{Check Tag|Thought template}} thought in place of the regular {{Good|+40}} that other mental breaks have.

==Major break==

===Social drug binge===
{{See also|Mental break#Hard drug binge{{!}}Hard drug binge}}
[[File:SocialBinge.png|thumb|right|Social Drug Binge]]

Causes the pawn to drink or smoke their problems away by binging on [[social drugs]] (i.e. [[ambrosia]], [[beer]], [[smokeleaf joint]]s, [[psychite tea]]).

This can only happen if you have social drugs present in your colony.

:'''Mean time between Recovery:''' {{Ticks/gametime|8000}} <br>

Pawns with the [[Teetotaler]] trait will never have this mental break but pawns with [[Ideoligion#Drug_use|Negative drug use]] precept{{IdeologyIcon}} still can, in which case they may get a negative "used drug" moodlet dependent on the precept if they successfully act on the binge.
{{clear}}

===Psychotic wandering (Daze)===
[[File:Daze.png|thumb|right|Daze]]

Causes the pawn to wander around aimlessly, eventually recovering on their own. The letter informing you of this break refers to it as a "Daze."

Affected colonists can ignore [[food restriction]]s. This can push the colony to collapse, especially with few colonists and without enough automation.

Dazed colonists can be [[prisoners|arrested]], which can be useful if they are in imminent danger.

Unlike sad wandering, [[prisoners]] can stage prison breaks whilst in this mental state. They will still wander around aimlessly, but will be able to open doors. They may still attack colonists if caught in melee.

===Psychotic wandering (Daze) Short===

=== Tantrum ===
Causes the pawn to take out their anger on the structures in the colony, randomly punching at (and possibly destroying) them. The attacks may create [[Filth#Building_rubble|building rubble]] in the process.

=== Targeted tantrum ===
Causes the pawn to take out their anger on a single structure or stack of items, punching at them until eventually destroyed. The tantrum will redirect to another structure or stack of items if that structure or stack of items is destroyed or made inaccessible.

Targeted tantrums are significantly more dangerous than the non-targeted variety, as the pawn has a much higher chance of actually destroying things instead of simply damaging them. They are especially dangerous when the pawn targets mortar shells (beware the [[antigrain warhead]]), which explode upon destruction, or if they attack important stacks such as stacks of components or medicine that the colony relies upon.

=== Corpse obsession ===
[[File:Corpse obsession.png|thumb|right|Corpse obsession]]
Causes the pawn to go to a grave or sarcophagus, dig up a corpse and drop it on a high-traffic spot, such as a table in a dining room. The obsession will then end.

This break can only occur if you have a filled grave or sarcophagus. The pawn is required to be capable of [[manipulation]].

While this break is somewhat quick, it can potentially bring "Observed corpse" mood debuffs to whoever sees the corpse, and can trigger a colony-wide "Colonist left unburied" mood debuff if the corpse was of a colonist.

=== Insane ramblings ===
{{Anomaly|section=1}}
Causes the pawn to mindlessly wander around and spout utter nonsense every 10-15 seconds. Essentially a major variation of the dark visions break.

Much like dark visions, nearby colonists will experience negative thoughts, and the rambling pawn will gain a {{Good|+30}} thought upon recovery.

{{Ideology|section=1}}
Occurs in place of any mood-related mental break in colonists following an [[Ideoligion]] with the [[Ideoligion#Inhumanizing|Inhumanizing: Required]] precept. The pawn will wander around for some time and after recovery, will receive the [[inhumanized]] permanent hediff that prevents them from experiencing the break instead, among other things. They will gain a permanent {{Good|+8}} thought in place of the standard catharsis thought.

==Extreme break==

===Berserk===
[[File:BerserkScreenshot.png|thumb|right|Berserk]]
The pawn will lose total control, melee attacking any living creature near them. They will not intentionally kill anything, although unlucky hits may still result in death, instead redirecting to another target once their current target is downed.

Pawns that are [[Work#Incapable_of_work_types|incapable of violent]] can still go berserk. Berserk colonists are able to use doors that are forbidden, and don't close doors behind them (auto-doors included). Berserk prisoners will bash at doors until they break.

Subduing the berserk pawn with bare fists or a blunt weapon poses the least risk of killing them. Once a berserk pawn is subdued, the break is over. They do not need to be arrested, and can be immediately rescued to recover from their injuries. If the berserker is not in danger and can be safely avoided, it can be best to leave them to rampage by themselves until their berserk rage wears off to avoid injuries.

=== Fire starting spree ===
[[File:Fire Starting Spree.png|thumb|right|Fire Starting Spree]]
Causes the pawn to go on a fire starting spree, targeting flammable materials and setting them ablaze.

Only [[pyromaniac]]s can suffer this break. It will replace all extreme breaks that they would otherwise suffer, as well as occur randomly, regardless of mood, with an {{MTB}} of 50 days. Pyromaniacs do not gain the Catharsis thought after these random fire starting sprees but will for sprees caused by low mood.

The [[pyrophobia]] gene{{BiotechIcon}} suppresses the pyromania trait entirely, including this mental break.

Fire-starting sprees are very short and can easily be dealt with by having somebody else "babysit" the pyromaniac, putting out fires as the pyromaniac pawn starts them. However, it is worthwhile to consider that they may also target volatile objects such as [[chemfuel]].

=== Hard drug binge ===
{{See also|Mental break#Social drug binge{{!}}Social drug binge}}
[[File:HardBinge.png|thumb|right|Hard Drug Binge]]

Causes the pawn to binge on [[hard drugs]] (i.e. [[flake]], [[yayo]], [[go-juice]] and [[wake-up]]).

Hard drug binges are considerably more dangerous for the affected colonist's health than social drug binges, as hard drugs contribute towards [[overdose]]s which are potentially lethal, and can easily lead to an addiction and/or chemical damage. As with social binges, hard binges will either end when the affected colonist goes to bed, or after a certain amount of time has passed. Colonists taking [[penoxycyline]] and [[luciferium]] have nothing to do with the drug binge they are on.

Pawns with the [[Teetotaler]] trait will never have this mental break but pawns with [[Ideoligion#Drug_use|Negative drug use]] precept{{IdeologyIcon}} still can, in which case they may get a negative "used drug" moodlet dependent on the precept if they successfully act on the binge.

===Catatonic breakdown===
Causes the pawn to enter a ''catatonic breakdown'' state, where they become incapacitated and need to be rescued.

This is one of the least immediately harmful of the extreme breaks as it does not result in injury or damage to colonists or structures. However, the affected colonist will be down for quite a long time, and unable to perform any work. This can be especially detrimental if the colonist performs a vital task in the colony.

Since catatonic breakdown is technically a health condition, usage of the [[healer mech serum]] or [[unnatural healing]]{{AnomalyIcon}} can instantly bring the affected colonist out of the mental break.

Only colonists can experience this mental break. Pawns from other factions, not under the players control, will not. Temporary colonists from [[quests]] or from [[permits]] {{RoyaltyIcon}} can experience this mental break.

This mental break does not trigger the Inspired Creativity [[mental inspiration]] from the [[Tortured artist]] trait.

=== Jailbreaker ===
[[File:Jailbreaker.png|thumb|right|Jailbreaker]]

The pawn will move to the targeted prisoner, and upon reaching them, a [[prison break]] event will trigger. Afterwards, the mental break will be changed to something else.

The pawn can be arrested or downed before reaching the prison cell.

=== Slaughterer ===
Causes the pawn to slaughter tamed animals at random.

If you have a lot of tamed animals this usually won't cause major losses, but there's a chance the maddened colonist may decide to butcher a [[bond]]ed animal, a [[boomalope]], or your favorite tamed [[thrumbo]], none of which are "good" outcomes.

=== Murderous rage ===
[[File:Murderous rage.png|thumb|right|400px|Murderous rage]]

Causes the pawn to select a random colonist or prisoner and melee attack them until they are dead. Once the target is killed the break is over.

This requires intervention from other colonists if the life of the victim is to be saved.
#This can be interrupted by attempting arrest. If it is successful, the colonist will quietly submit and go to prison along with the warden. Otherwise, the colonist will instead go berserk and will lash out at nearby colonists instead, which may be easier to deal with as the colonist is no longer hellbent on killing one person.
#If the murder target is rescued or otherwise becomes unpathable to the maddened colonist, they will instead select a new victim.

This break can occur in pawns placed temporarily under your control, such as those provided by [[quests]] or from [[permits]] {{RoyaltyIcon}}.

It is ten times less likely to occur in a colony with a population of two, and it increases linearly to the normal level at a population of seven or more.

=== Run wild ===
Causes the pawn to run into the wild and start acting like an animal. While acting like an animal, the pawn will subsist on wild sources of food, usually berry bushes or agave in arid biomes. They may wander across spike traps and randomly trigger them.

Unlike other breaks, this one lasts indefinitely without intervention. The only way to end it is to have another colonist tame the broken colonist and convince them to act like a human again. Taming a wild man is equivalent to taming an animal of 75% wildness, equivalent to an [[elephant]] or [[fox]], and requiring an [[Skills#Animals|Animals]] skill of 7 or greater.

Damaging them until they are downed isn't an advisable option; since they don't belong to your faction anymore, they will most likely die upon receiving enough damage to become incapacitated. Using a [[psychic shock lance]] to down them will ignore the storyteller [[death on downed]] chance, however there is always the risk of brain damage. If rescued, they have a chance to join you upon recovery.

Upon taming, they will have their usual Catharsis moodlet, and will have their Beauty and Comfort needs set to 50%, while their Outdoors needs is set to 100%.

It is much less likely to happen at lower population levels.

Additionally, it appears that this mental break does not trigger the Inspired Creativity [[mental inspiration]] from the [[Tortured artist]] trait, however more testing is needed.{{Check Tag|Verify}}

=== Given up and leaving ===
Causes the pawn to decide they've had enough with the colony, and leave entirely.

This can be countered either by arresting the colonist, or incapacitating them by force. Sometimes a pawn can decide to return to the colony after having this break, but before they have left the map. For example, this can happen if the colonist is in the [[labyrinth]],{{AnomalyIcon}} which they cannot leave - the colonist will simply wander around the labyrinth for a while before "deciding" to stay in the colony. It is currently unclear what controls the rate of this occurrence. {{Check Tag|Detail needed}}

Quest lodgers and [[slaves]] cannot get this mental break. It will never occur if there are seven or less members in the colony, and the frequency increases linearly, capping at twelve colonists.{{Check Tag|Values?}}

=== Crisis of belief ===
{{Ideology|section=1}}
{{Stub|reason=Confirmation and detail on how the weighting used to choose the replacement ideoligion is calculated - see GetIdeoWeight function}}
A pawn undergoes a crisis of faith in their [[ideoligion]], losing 50% of their [[Certainty]]. Unlike many forms of Certainty loss, this value is not modified by the pawn's their [[Global Certainty Loss Factor]].

Should this loss be sufficient to reduce the pawn to 0%, they will instead immediately convert to a different ideoligion. This ideoligion is randomly selected from all ideoligions in the current world, including the player's, with weighting based on the following factors:
* Every ideoligion has a base value of 1.
* +1 for each [[faction]] with that ideoligion that is allied to the breaking pawn's faction
* +1 for each spawned pawn with that ideoligion, on any map, that is the same faction as the breaking pawn
'''AND EITHER'''
* +1 for each spawned pawn on the same map from the same faction as the breaking pawn, or from a non-hostile faction.
'''OR'''
* +1 for each pawn with the ideoligion currently on a caravan, if the breaking pawn is currently on a caravan.
The random generator will never return the pawn's current ideoligion.

=== Terrifying hallucinations ===
[[File:Terrifying Hallucinations Demo.png|thumb|right|Terrifying hallucinations]]
{{Anomaly|section=1}}
The pawn will break down and start to hallucinate, seeing fellow colonists as nightmarish figures and will flee from anyone they perceive as a threat.

Whilst a pawn is in this state, shadowy figures will swirl around the afflicted pawn and they will ramble insane nonsense every 10-30 seconds. Much like other nonsensical rambling mental states, other colonists will be slightly upset by the afflicted pawn's nonsensical gibberish. The break may end when the pawn goes to sleep.

== Special ==
These mental states aren't mood-related, and have certain circumstances required to trigger them.

=== Confusion ===
[[File:Confusion.png|thumb|right|Confused and wandering]]

Similar to the 'Sad Wandering' mental state, except confused wandering only occurs on a pawn with Alzheimer's or Dementia, as well as those still woozy or recovering from anesthesia.

This mental state is similar to psychotic wandering in the respect that confused pawns are prone to wandering into dangerous situations, however they do not strip off their equipment. This mental state ends after a certain period of time, or when the affected pawn is downed or killed. All normal thoughts are blocked during this time frame.

It can also occur in animals after their [[bond]]ed master dies.

=== Social fighting ===
[[File:Social fighting.png|thumb|right|Traders social fighting]]

Social fighting is triggered when one pawn slights or insults another (significantly more likely with insulting than slighting), and the affected pawn gets angered. While very brief and usually only resulting in minor-moderate injury, social fighting can also end up with much worse results including a pawn getting downed, disfigured, or uncommonly even outright killed. Social fighting ends after a very short time, or when one of the fighting pawns gets downed or killed.

=== Fleeing in panic ===
[[File:Fleeing in panic.png|thumb|right|Fleeing in panic]]

This sort of mental break happens when half (rounded up) of a group of non-colonist humanlikes are killed; whether it be hostiles, traders, or the like. Pawns affected by this mental state will attempt to leave the map by any means possible as soon as they realize that they're not going to win whatever battle they got caught up in.

This mental state will end once the affected pawn leaves the map, or when they're killed.

Pawns in this state will run indiscriminately towards the closest edge of the map, completely disregarding any hostiles in the way (such as your colonists firing at them), trying to smash down doors even when there is a clear path out next to them.

=== Fleeing fire ===
{{Biotech|section=1}}
{{stub|section=1|reason=Mechanic details + numbers.}}
This sort of mental break happens when a pawn with [[Pyrophobia]] gene happens to be near the fire. It will cause them to flee far away from the source of fire.

This mental state will end once he or she no longer see fire within their field of vision.

The affected colonist does not gain the [Catharsis] mood buff from fleeing fire.

=== Manhunter ===
{{For|the [[event]] that causes a pack of animals affected by this break to spawn on the map|Events#Manhunter pack}}
Animals may suffer a manhunter mental break, similar to [[Mental break#Berserk|berserk]]. A manhunter animal will seek out and attack any humans and [[Mechanoids]]. Animal pulser maddened animals will attack mechs on the map it can reach, regardless of faction, but will ignore tamed animals.

Manhunters will not spontaneously attempt to break through obstacles to hunt down pawns, but will attack doors if they see someone go through them. They will cease their attack after a short period, but may still successfully break it down in that time. If strong doors are not available to hide behind, try to get out of line of sight before ducking into a nearby building, be ready to repair the door from the inside, or simply accept that the door is only a temporary barrier.

The mental break can be triggered in several ways:
* Via the [[Events#Mad (Animal)|Mad Animal]] event. Affects 1 wild animal.
* Via the [[Events#Psychic Wave|Psychic Wave]] event. Affects all wild animals on the relevant map.
* Via the use of a [[psychic animal pulser]]. Affects all non-player owned animals on the relevant map.
* Via the use of [[Manhunter pulse|Manhunter Pulse]]. Affects all animals (including player-owned animals) within the target radius.
* Via injury inflicted by any humanlike pawn. Chance is controlled by the animal's "Manhunter Chance", the [[hunting stealth]] of the injuring pawn, and the distance between the pawn and the animal. Affects the injured animal, and in the case of certain herd animals, any nearby animals of the same species.
* Via a failed taming attempt angering the animal. Chance is controlled by the animal's "Manhunter Chance (Taming)". Affects the targeted wild animal.{{Check Tag|Herd?|Can this trigger herd revenge as well?}}
* Via the death of their [[bond]]ed master.{{Check Tag|Chance?}} Affects any tamed and bonded animal

An animal's manhunting rampage will end after a certain amount of time, upon the animal sleeping, or once [[downed]].

Manhunter animals with [[Scaria]] can not be [[tame]]d without first curing them. Attempts to [[prioritize]] the taming task will result instead in a hint saying ''Animal busy''.

:'''Mean time between Recovery:''' {{Ticks/gametime|18000}} <br>
:'''Minimum time until Recovery:''' {{Ticks/gametime|10000}} <br>

=== Manhunter Permanent ===
Permanent manhunter is randomly applied to animals that are part of a [[manhunter pack]]. Affected animals will never snap out of this mental state under normal circumstances, and completely neglect their own needs. Animals in this state will generally leave the area within a few days.

Some manhunter animals, such as [[boomrat]]s, will typically starve to death due to their hunger rate combined with the typical manhunter animal duration.

:'''Minimum time until Recovery:''' {{Ticks/gametime|99999999}} <br>

=== Roaming ===
Introduced in 1.3, farm animals (animal species that cannot be controlled via zones) can randomly get this mental break if they are outside of an enclosed pen. This can cause them to leave the map if not roped in immediately. If they are enclosed in a pen, or if they are roped in by a colonist after a valid pen is placed, this mental break will immediately end.

This does not occur on maps where they have recently been brought in, or on maps the other colonist are raiding in.

:'''Minimum time until Recovery:''' {{Ticks/gametime|99999999}} <br>

=== Berserk (short) ===
{{Anomaly|section=1}}
A shorter variation of the berserk break that occurs due to buildup of [[Blood rain|blood rage]]. Functions identically to its classic variant.

:'''Mean time between Recovery:''' {{Ticks/gametime|10000}} <br>
:'''Minimum time until Recovery:''' {{Ticks/gametime|10000}} <br>
:'''Maximum time until Recovery:''' {{Ticks/gametime|15000}} <br>

=== Manhunter (blood rain) ===
{{Anomaly|section=1}}
A variation of the manhunter mental state that occurs due to buildup of [[Blood rain|blood rage]]. Functions identically to its classic variant.

Whilst it eventually comes to an end after the blood rain comes to an end, it will not stop whilst the afflicted animal goes to sleep, is downed, or collapses due to extreme exhaustion.
:'''Minimum time until Recovery:''' {{Ticks/gametime|15000}} <br>
:'''Maximum time until Recovery:''' {{Ticks/gametime|30000}} <br>

=== Cube sculpting ===
{{Anomaly|section=1}}
Randomly happens in pawns with an interest in the [[Golden cube]], where they will build a sculpture on the ground in the shape of a cube. This may be made of sand, dirt, or miscellaneous scrap, depending on the surface. The break will then immediately end.

It is important to mention that these sculptures are affected by [[quality]], therefore a pawn with an Inspired Creativity [[mental inspiration]] may use their inspiration on a cube sculpture.

:'''Minimum time until Recovery:''' {{Ticks/gametime|20000}} <br>
:'''Maximum time until Recovery:''' {{Ticks/gametime|35000}} <br>

== Tips ==
* [[Arrest]]ed [[prisoner]]s and [[prison]]s are more expensive than random damage of most mental breaks, imprisoning is usually more worth it if the mental break needs to end quickly such as during raids and when something needs to be dealt with immediately.
* Pawns during a mental break are immune to damage from [[Unnatural darkness]]{{AnomalyIcon}}, however once the mental break ends this immunity subsequently ends as well.
* [[Wimp]]s are easier to deal with during their mental breaks if avoiding imprisonment, because the lower pain shock threshold makes them be downed with less injury. The [[extra pain]] gene{{BiotechIcon}} can be installed on pawns to add the trait.
* Pawns with [[artificial body parts]] that are subject to [[brain shock]] can be easily, safely, and instantly downed upon any exposure to [[EMP]]. Note that as of the time of writing, the only parts that apply this effect are from the [[Royalty]] DLC.

== Version history ==
* [[Version/0.3.410|0.3.410]] - Mental break probability is much lower.
* [[Version/0.9.722|0.9.722]] - Binge mental break added
* [[Version/0.12.906|0.12.906]] - Dazed broken pawns will now randomly strip off clothes and drop things.
* [[Version/0.14.1234|0.14.1234]] - Added new class of “minor” mental breaks. Added minor mental break: food binge.
* [[Version/0.18.1722|0.18.1722]] - Added the following mental breaks: Insulting spree, Targeted insulting spree, Tantrum, Bedroom tantrum, Targeted tantrum, Sadistic rage, Corpse obsession, Catatonia, Jailbreaker, Slaughterer, Murderous rage, Run wild.
* Beta 19/ 1.0 - Overhauled mental break probabilities. Aside from some exceptional cases, all mental breaks are more or less equally probable.
* 1.1 - the way the different mental break thresholds were calculated was changed. Previously the major break thresholds and minor break thresholds were locked to base threshold + 15% and +30% respectively, with the base threshold at 5% for normal pawns; as a result, the mental break thresholds could be reduced by a maximum of 4% only, leading to the Iron-willed and Steadfast [[traits]] being weaker than expected.
* [[Version/1.2.2753|1.2.2753]] - Disable corpse obsession break for prisoners, as it's very unlikely to happen and is not implemented around this possibility.
* [[Version/1.3.3066|1.3.3066]] - Fix: During food binges, sometimes pawns will use recreational drugs.
* [[Version/1.4.3542|1.4.3542]] - Fix: Quest lodgers can do the "give up and exit" mental break.
* [[Version/1.4.3555|1.4.3555]] - Fix: Bloodfeed can be used on pawns in mental states.

{{For|caravans visiting you from other factions|Trader}}

'''Caravans''' are a group of one or more colonists who gather together for different purposes and leave the current map tile. Goods can be carried by animals, colonists, or prisoners to facilitate trading on your own schedule; a caravan can also act as a raid squad to attack other establishments. Each caravan is represented on the [[Menus#World|world map]] by a yellow icon. Double-clicking a caravan will select all caravans on the screen, allowing them all to be ordered to a single destination.

Sending caravans out from your home, instead of just waiting for other tribes to come to you, creates trade opportunities at your pace, rather than waiting for random traders to arrive at your location. It also provides a wider selection of goods since friendly outposts have much more inventory than the limited selection traders (who are restricted by carrying capacity) show up with. Also, you get a 2% price bonus for direct trading. It also avoids the cost for requesting traders at the [[comms console]].

|-
| Form caravan
| Abandon settlement
|}

In the World map, select the colony icon and click <tt>'Form caravan'</tt>. A dialog is shown to assign pawns, animals, and items. You can create multiple caravans.

: <p>'''''Caution:''''' Clicking <tt>'Abandon'</tt> on an unoccupied colony will not prompt for any confirmation before making it an [[:File:Abandoned faction base.png|inaccessible ruins and lost forever]].</p>

=== People and Animals ===
When forming a caravan, the first pop-up menu has the player choose which pawns will join the caravan, including colonists, [[animal]]s, any [[prisoner]]s you want to transport, and, if you have [[Biotech]], any [[Mechanoid]]s your Mechanitor{{BiotechIcon}} possesses. At least one colonist must be chosen.

There are three different ways that caravans are formed:

* A caravan ''without'' pack animals forms the quickest. Colonists only need to pack items into their personal inventory and can exit the map rather quickly.
* A caravan ''with'' pack animals suffers from a loading phase where colonists must load selected items into the animal's inventory. This can take a long time if there are lots of items to pack or there aren't many [[work#haul|haulers]] available.
* A caravan already traveling in the World Map will reform instantly and not require a loading phase, regardless of pack animals.

Incapacitated pawns cannot be chosen to join the initial caravan. Once your caravan is traveling, though, colonists can carry incapacitated humans and animals at a normal speed.

The caravan will take the name of the best negotiator in the caravan (highest social skill.)

Mechanoids {{BiotechIcon}} inside a caravan without their overseer Mechanitor cannot be commanded to do anything when drafted as there is no signal for them to move or command to move towards, but can still be brought over as a caravan as long as the Mechanitor in question still has enough bandwidth to maintain their control in anywhere. Mechanoids will always add their carrying capacity to the caravan, regardless of whether their overseer is in the caravan.

[[File:Caravan party.png|300px]]

=== Items ===
Use the Items tab to select supplies. Only items located in your Stockpiles or Home Area are shown while initially packing; when reforming the caravan, you can select any item on the map.

The carrying capacity of humans and [[Pack animal|pack animals]] in a caravan is separate from their [[Carrying Capacity]] for hauling, and is given by their Body Size multiplied by 35. For humans, this includes the clothing, gear, and inventory that they already have.

Caravan carrying capacity:
{| {{STDT|c_08 sortable align-center}}
! Name !! [[Property:Type|Type]] !! [[Property:Pack Capacity|Pack capacity]] (kg)
{{#ask: [[Category:Pack Animal]] OR [[Pack Capacity::+]] [[Resource 1::+]]
| ?Type
| ?Pack Capacity
| sort = From DLC, Type, Name
| format = template
| template = Ask Table Formatter
| link = none
}}
|}

Baby or juvenile animals have a reduced carrying capacity according to their body size.

If the colonist or animal is already carrying something (such as clothes worn), they will appear to have a reduced carry weight.

The combined carrying capacity and mass of selected items is listed at the top. Buttons are used to select items/amounts. A double arrow [>>] will take the full quantity of an item. The arrow [>M] indicates you cannot carry the full quantity, but it will automatically take the maximum amount. When over capacity, the arrow [M<] will return some or all of those items so that the mass total does not exceed the caravan's carrying capacity.

Modifier keys can be used to change the [>] and [<] arrows from +/−1 to:

* {{Key|CTRL}}: +/−10
* {{Key|SHIFT}}: +/−100
* {{Key|CTRL}}+{{Key|SHIFT}}: +/−1000

If a caravan member dies in the close-up view, they will drop their items which must be picked up. If they die on the global map (such as from blood loss), their gear will be lost. If all party members die, the entire caravan disappears and everything is lost.

[[File:Caravan inventory.png|300px]]

==== Food ====

Caravan members will feed as needed while traveling or resting, so long as there's food in the caravan inventory ''and'' they are [[Food policy|assigned]] to eat a type of food being carried. Colonists who are part of a caravan will automatically forage for raw food, with yield depending on the environment and the colonist's Growing [[skill]]. Foraging is not recommended as the caravan's ''primary'' food source, however, as it may result in food poisoning (2% chance/meal) like all raw food consumption.

Herbivorous animals can generally graze on their environment for nutrition while traveling, except in extreme biomes like ice sheets and deserts. However, carnivorous and omnivorous animals cannot hunt nor scavenge while traveling in a caravan. Extra appropriate food must be brought for them or they will starve.

A caravan's '''time to destination''' is displayed in the inspect pane when a caravan is selected on the World Map screen. This allows for careful coordination of trip length and food stores when planning a caravan.

Most food spoils without refrigeration rather quickly. Supplies with the soonest expiration date are automatically consumed first.

* [[Simple meal]]s will suffice for short journeys (spoils in 4 days).
* [[Berries]] can last through mid-length journeys (up to 14 days), although they are less weight-efficient and add the chance (2%/meal) of food poisoning.
* [[Pemmican]] is useful for long-distance travel (lasts over 1 year).
* [[Packaged survival meal]]s are also excellent for long journeys (never expire).

While traveling, [[caravan#events|caravan events]] may trigger such as [[manhunter pack]]s or pirate raids, all of which generate ''mini-maps''. After threats have been eliminated, it's possible to scavenge a mini-map for food, game, herbal medicine, and other resources. All animals will automatically feed in a mini-map.

After lingering on a mini-map for several days, the storyteller will spawn a raid as a way of forcing you to ''reform the caravan''.
Upon reforming a caravan, all items, animals, and pawns must be manually selected to be included with your reformed caravan, or they'll be lost forever.

=== Formation process ===
{| class="wikitable" style="text-align:center;"
| [[File:Forming Caravan.png|Badge for pawns forming caravan|64px]]

Once the order to form the caravan is given, colonists and animals will gather around a [[caravan hitching spot]] or a random place within your home area and wait for all members to assemble.

It's recommended to put the caravan hitching spot inside your warehouse to reduce loading time.

After assembly, they will gather any needed supplies, putting them on pack animals if available. When they finish, they will head out to the map edges and wait for the other members to arrive, then exit the colony map and enter the world map.

Haulers not part of the caravan will also help in gathering the supplies.

[[File:Caravan loading.png|500px|thumb|none|Notice the loading process as colonist start to take items towards the animals of burden.]]

Colonists will ignore any needs during the formation, except food (once they're starving they'll take a break to eat if food is available). Should they feel exhausted during the process, they won't rest in their bedrooms but collapse near the caravan hitching spot.

They will also override the 'Forbid' command, taking forbidden items. If there is less of an item than ordered (e.g. meals which other colonists ate during the process), members will take what they can and then carry on without stopping.

A pawn can be temporarily interrupted by manually assigning them to do another task. They will resume caravan loading once the task is complete.

Any mental break of its members will pause the process until that member recovers. Downing or killing that member will interrupt the process, causing it to be canceled.

[[File:The caravan formation process will continue when everyone recovers from a mental break.png|500px|thumb|none|Ufff...]]

If the formation was successful, the character roster on top of the screen will split, showing those who stayed at home and those who left with the caravan by greying them on a different "box".

[[File:Colonist roster of those at home and at caravan.png|500px]]

=== Caravan route & pathing ===
The 'Choose Route' button allows the player to set destinations for a caravan. Right-clicking a tile on the World Map will create a float menu with travel options. The quickest route to a destination is automatically calculated, taking terrain types and roads into account.
Once a destination tile and inventory are chosen, traveling colonists will collect items to their inventories and then exit the map.

</gallery>

=== Tricks ===
* If a caravan includes a lot of animals or items, the process of gathering those can be ''very'' time-consuming. Starting a larger caravan at 0400, it's not unusual to leave (well) after 1200, 8+ hours of "Forming Caravan". To reduce this time, you can add additional pawns to the Caravan roster, dedicating them to the loading process, either when you create the Caravan or after (by selecting a pawn and clicking "Add to Caravan"). You can remove them prior to exiting the map in the same way. This may not be necessary, as in 1.5, it has been observed that non-caravan colonists help out with loading/unloading. You can even create the caravan with one set of pawns, add others, and remove the original set; this is handy to start the process as soon as possible if your desired travelers are busy early in the morning, or you just want them to get as much sleep as possible before the journey.
:* If you remove colonists from the caravan ''before'' leaving, their animals are released to wander and must be re-gathered by the (fewer) remaining caravaners, which might take another hour or more. It may be a better idea to let all colonists leave the map together, then immediately pause the game and jump to the World Map, select the caravan and click "Split Caravan", sending whichever colonists you wish instantly right back to the base map while the main caravan body continues on. Be sure the carrying capacity of the remaining pawns is enough to carry all the intended items.

* Sometimes you start forming a caravan late in the day, or realize you won't make the 2200 cut-off for traveling that day. If you wait until ''after'' 2200 (when domestic animals sleep), you can create un-owned [[animal sleeping spot]]s around the [[caravan hitching spot]], un-form the caravan, and the (still-packed) animals will bed down there for the night. If you then start early the next morning (''well'' before they start to wake around 0600), the animals are near to the hitching spot and easy to round up when you re-create the caravan. There may be some unpacking/repacking of items, but your colonists won't have to chase the same animals all over the map again.

* The act of gathering supplies allows a colonist to carry huge stacks of lightweight materials like cloth or food. This can be exploited to perform ''Super Hauling'' by having a colonist pick up all the goods on the map, drafting them into the storage room, and cancelling the caravan to unload. They will have hauled a massive number of supplies in one trip.

* Faster unloading caravan with lots of carriage: before entering the home cell while returning home, choose another route that will take you through the settlement cell. When the caravan is moving over the center of the base on the world map split it off all creatures except one pawn. That one pawn will become immovable due to overload, but You will be able to click on settlement and choose the option to enter. Then, you can draft him to stockpile and unload all items with a down-pointing arrow button from the inventory screen. If a returning caravan has only one pawn, you can make another one to meet him near to be able to split.

Once your caravan enters the world map, you can give it orders.

A caravan can:
* '''Move''' - Right-click to select destination. A line indicates the optimal route (accounting for terrain speed and elevation changes).
* '''Settle''' - Click Settle to create a new colony.
** You may not settle a new colony when already at maximum. The default maximum is one. This can increased to up to five in Menu - Options.
** Settling directly adjacent to your own colony or any other settlement is not allowed.
* Enter back into the colony - Right-click the colony.
* '''Split''' - Click the Split button. Each caravan must consist of at least one colonist.
* '''Merge''' - Select two or more caravans in the same tile (by dragging a square zone) and click Merge to form a single caravan.
* '''Trade''' - When a caravan has reached a friendly faction outpost, click the trade button to open the trade dialog window.
* '''Attack''' - A caravan can attack any faction outpost, regardless of relations status, though attacking will worsen relations.
* '''Offer gifts''' - If your relations with a faction are not high enough to trade, you can offer them gifts in an attempt to improve relations.

[[File:Caravan optimal route.png|300px]]

=== Status box ===

Several items are displayed in the status box.

# Movement status:
#* Traveling - moving to destination.
#* Resting - caravan automatically stops between hours 22 and 6 to sleep.
#* Waiting - no destination selected.
#* Stopped - stopped moving with reason given.
# Estimated time to destination - time to destination based on the current tile movement time.
# Days of food - number of days before your caravan runs out of available food. If your caravan is low on food, the player receives a text note on the side of the screen. Caravans with low food are also warned before exiting the map. Compare the days of food to 'estimated time to destination' to determine if your caravan has enough food for the journey.
# Base movement time: Movement speed based on rideable animals, carried mass, mass capacity, and terrain. Pawn's manipulation, moving, move speed do not impact movement speed.
# Current tile movement time: Current movement speed based on the terrain, biome, weather (only affected during autumn-winter) or roads. (See table on this page for details.)
# Visibility: How vulnerable your caravan is to ambush attacks. Visibility is affected by the ratio of inventory mass to caravan carrying capacity.

A caravan may stop for various reasons, such as:

* Between hours 2200 and 0600 while the members sleep and rest.
** They will still rest even if all members are fully rested.
** Caravans sleep during those hours regardless of what the colonists are assigned in the Schedules menu.
* When all colonists are downed or having a minor/major mental break.
* When any member is having an extreme mental break.
** Nobody will be harmed even if the colonist is going berserk.
** Minor or major mental breaks won't stop the caravan as long as at least one person is still functional. If a colonist is in the midst of a mental break when you settle or get ambushed, they will still be having it when they appear on the map.
* If the player manually pauses the caravan.
** Paused caravans forage faster, members can socialize, and the caravan is less likely to be attacked.

=== Sustenance ===
Pawns traveling in a caravan will eat automatically when necessary. Grazing animals, when hungry in a place with grazable plants, will instantly have their hunger bar refilled without any cost. If not, they will proceed to eat food carried in the caravan. Pawns will prioritize food that spoils earlier. If there is insufficient food to feed the entire caravan, humans will be fed before animals.

If a colonist has an injury or disease that requires tending, doctors will tend to them as necessary, using medicine if available to them. If self-tend is on they will also tend to themselves.

If you bring [[Beer]] along with you, colonists may consume it during their journey. The mood bonus it provides can help keep colonists sane when away from the colony for long stretches of time.

==== Foraging ====
{{Rewrite|section=1|reason=Cleanup, verification, integration with [[Foraged Food Amount]]}}
Every colonist and [[slave]]{{IdeologyIcon}} in a caravan can forage for raw food.
Each colonist can forage 0.09 nutrition per day per level of [[Skills#Plants|Plants]] at a baseline, i.e. in temperate forests or swamps. Given that each colonist consumes 1.6 nutrition per day, this means that a level 9 Plants colonist can break even with food consumption when the caravan is resting, and a level 18 Plants colonist can constantly forage more than he eats while traveling.

Foraging is also affected by manipulation (50% importance, 100% max) and sight (90% importance), so giving caravanners [[bionic eye]]s or [[archotech eye]]s increases foraging.

Having a tribal start grants a 170% multiplier to foraging, as shown by a "Faction Type: 170%" line in the tooltip. This means that in temperate forests or swamps, a level 6 Plants colonist will break even with food consumption when the caravan is resting, and a level 11 Plants colonist can constantly forage more than they eat while traveling. If Tribal colonists with good Plants skills have enough meals or other food to eat during a trip through terrain with good forage, they may return with a nontrivial quantity of berries.

==== Energy ====
{{Biotech|No Category}}
When on the world map, [[Mechanitor|friendly mechanoids]] consume no power. However, if a mechanoid does run out of power during the caravan, such as during an ambush, it will go under a permanent Dormant Self-charge state until someone brings it to a nearby mech recharger.

=== Recreation ===
Colonists on caravan gain [[recreation]] while stopped at a rate of 10% per hour, of the Solitary type if they are alone, or a mix of Solitary and Social if two or more colonists are on the same caravan. Tolerance is gained at an equivalent rate to Extremely Low Expectations, regardless of the expectations at the colony or the amount of wealth taken on the caravan.

=== Psyfocus ===
{{Royalty|No category}}
Pawns in a caravan will also regenerate [[psyfocus]] while remaining stationary or waiting.{{Check Tag|Rate?|How much psyfocus per hour? Add to both Psycasts and Caravan}} This, however, does not apply when the caravan is resting due to sleep. This allows for usage of psycasts even while on long caravan journeys, provided some time is taken off to recharge.

=== Caravan schedule ===
{{Stub|section=1|reason=This section and its subsidiaries are rough outline only - it needs verification, expansion and clean up. Additionally: never sleep is also faster when they wouldn't have to travel the whole night to get home - either because they started not first thing in the morning or the travel time is >18hrs by riding but not 24 hrs by riding and not 24hrs by foot}}
All caravans start moving at 0600 hours and stop at 2200 hours, and they rest while not moving. This travel routine is adhered to regardless of pawn traits or [[Assign|schedule]], i.e. a [[night owl]] pawn scheduled to sleep during the day will still caravan from 0600 to 2200 hours. If a newly formed caravan leaves the colony map after 2200 hours, it will enter the world map and rest until 0600 the next morning. Similarly, if they don't reach their destination tile by 2200, they will stop to rest, even if they are just a single tile away.

The exception to this mandatory rest period involves a caravan with no animals and a caravan where all human caravan members have either a [[circadian half-cycler]]{{RoyaltyIcon}}, the [[never sleep]] gene,{{BiotechIcon}} or the [[body mastery]]{{AnomalyIcon}} trait, with or without mechanoids{{BiotechIcon}}. If this is the case, the caravan will continue traveling 24 hours a day. Though the practicality of doing this is up for debate as, referring to the [[Caravan#Caravan Movement Speed|table]], if all members of the caravan are riding a horse (1.6 mount multiplier) it is 6.67% faster than all of them never sleeping. Therefore the only time 24/7 caravanning would be useful is in the early game when access to horses is limited and only slower mounts such as dromedaries or donkeys are available or when on an extreme temperature tile like the ice sheet. It's also worth noting that caravanning pawns will do solitary or social recreation when the caravan is resting which could cause a 24/7 caravanning pawn to suffer mood penalties from recreation deprivation.

Note that if a caravan is partway between a tile and a settlement, camp, outpost, or similar map fixture, the caravan will continue traveling until they reach that fixture, even if it's after 2200. {{Check Tag|Details|Does it only occur when moving to a fixture, or does it also occur when moving away?}}

=== Caravan Movement Speed ===
Caravan movement speed follows the following equation:

{| class="wikitable"
| '''Caravan movement speed''' = (13.6 * Multiplier from Ridden Animals * Multiplier from Carried Mass)/Terrain Movement Difficulty
|}

Using this equation we can run an analysis on the value of different methods of caravanning, assuming a solo pawn and values for carried mass are 100% with a terrain difficulty of 1

Rideable animals, carried mass, mass capacity, and terrain all directly impact caravan movement speed.

===== Mounts =====
{{See also|Pack animals}}
{{Stub|section=1|reason=How do the inbetween ones work? If I have 1 at 1.6 and 1 at 1.3 do I get 1.45? Wb 1 at 1.6 and 10 without any mount? etc}}
Adding animals to a caravan may impose a multiplier on caravan speed based on the '''Caravan riding speed''' stat of the animal. The riding speed acts as a multiplier if there is one mount for every human pawn - for example, the caravan speed is multiplied by ×{{Q|Horse|Riding Speed}} if there is at least one [[horse]] for every human.

You get the full multiplier if you have enough mounts for everybody. You get something in between if you don't bring enough or have a mix of speeds.

| link = none
}}
|}

===== Carried mass ratio =====
Caravan speed also receives a multiplier based on the ratio of Mass Carrier/Mass Capacity. This is between 200% speed for zero mass and 50% (?) for maximum mass.

There is no distinction between carried and equipped mass - an equipped weapon weighs the same as it does when carried in a muffalo's inventory. However, some furniture like [[chair]]s have a lower mass than the materials they yield upon deconstruction.

Caravan speed can be increased by lowering carried mass (dropping items) or adding more pack animals, ultimately decreasing the Mass Carried/Capacity ratio. The speed multiplier will asymptotically approach 200%, thus number of pack animals used has diminishing returns.

===== Terrain =====
{{Rewrite|reason=Missing biomes and existing ones, and the effect of temperature and/or winter need to be verified.}}
The game will automatically plot the fastest route to your selected destination, so you will rarely have to pick and choose specific terrain.

The following table lists the movement difficulty of individual world tiles. Flat terrain is naturally the easiest to travel, while hills and mountains will slow you down. If the current temperature of a tile is under {{Temperature|-17.1}}, then movement difficulty will start to sharply increase, maxing out at +2 movement difficulty at {{Temperature|-22.5}} and below. This means cold biomes are easier to traverse in summer than in winter. The cold affects movement difficulty even in deserts where there isn't any snow.

If the tile contains a road, the movement difficulty for that tile will be halved. This is applied after all other calculations, and works the same regardless of the type of road.

Note that 1 movement difficulty roughly equates to 0.06 days or roughly 1.44 hours at base human movement speed.

=== Tabs ===
The inspection pane has tabs to manage the caravan and view details.

In the 'Gear' tab, by clicking the red X you can drop items and lose them forever. Dropping items may be necessary if the caravan becomes overburdened and unable to move.

You can also abandon colonists and prisoners in the 'Social' tab. Items carried by a dismissed pawn will be lost. Abandoning a caravan member will cause their friends and family to have sad thoughts, and if the colonist is unlikely to survive (such as low temperatures) there will be a more severe penalty. Colonists who survive may eventually make their way back to your colony, or return as part of an enemy raid or friendly caravan.

In the 'Gear' tab you can swap gear by dragging and dropping gear onto different colonists, or to and from the caravan inventory.

Once you arrive to the destination, just click the Trade icon to start negotiations.
[[File:Trade icon.png]]

=== Route planner ===
[[File:Caravan_planner.png|600px|thumb|rifht|Caravan planner having planned a route based a caravan's speed.]]

There is a route planner that allows you to roughly check the amount of time it takes to reach a destination, allowing you to plan ahead.

When it is opened, you can drop various waypoints around the world map. The game will calculate the time it takes for a 1 tile/h caravan to travel through the planned route. You can also place the starting point on an existing caravan to determine the time taken for a journey based on that caravan's speed.

Note that if you only place the waypoint at the destination(s), "caravan route time" only estimates a 1-way trip. To see the round-trip estimate, place another waypoint at home.

{{Clear}}

=== Returning home ===
After you arrive back at your colony, you will notice two details must be addressed before continuing the game.

* Pack animals may go straight to their animal bed or just wander around still with all your items inside their packing gear. If you happen to need something at the moment, you will have to make them drop it. You may want to restrict them to a roofed zone and wait for them to go there before doing this, so the dropped belongings won't deteriorate due to exposure, or you can wait until night when they are sleeping inside a room. Pack animals who have been trained for Obedience can be assigned to follow their master, who can be drafted to storage areas and wait until the animals follow him/her to drop the items as well.
* Prisoners will still be carrying your caravan items too, even armor and weaponry (as odd as it may be). They will not unload their inventory after returning to base unless directed to through the gear tab, but will instead have to be unloaded by haulers.

File:Caravan prisoner unloading inventory.png|'''Prisoner unloading inventory after recruitment'''
</gallery>

=== Long distance journeys ===

Many basic technology options prove to be very helpful for long distance travel. Make frequent use of [[Campfire]]s, [[Pemmican]], [[Passive cooler]]s and [[Crafting spot]]s to resupply your caravans and keep healthy on the road, instead of one large ride. Take advantage by [[camping]] whenever you run low on food or resources. Generated maps can have forageable food and animals to hunt or even tame into the convoy. Colonists will also need time off to relax and restore their joy.

=== Multiple colonies and pitstops ===

The game options let you choose how many colonies (up to 5) you can have active on the globe at once. Temporary maps from events do not count towards this limit. In order to build beyond the game menu limits, you must abandon an existing colony.

Should you choose to make multiple settlements, it is not necessary to carry all your raw materials all the way from your home base to a new spot. Lighten the load by carrying valuables such as silver, gold, [[drugs]] and then trading them with your new neighbors, or if you settled close enough, use [[transport pod]]s to launch everything over.

While traveling long distances consider bringing valuable items, then bartering for necessary supplies instead of bringing them.

If you know certain resources will be scarce in your new map's biome, or if you want to save time mining, some resources can be [[Advanced_Endgame_Guide#Resource_compression|compressed]] -- that is, built into items with a lower mass than their raw materials.

== Events ==
Caravan events take place on the road, which means that neither side will be engaging with the benefit of a base. The action takes place in the open and the player must take advantage of terrain features to defend themselves. Those who survive will have a 24 hours window to perform vital needs such as doctoring, resting and feeding as well as re-packing. [[:File:Pirate fed to animal.png|Eliminated hostiles can be fed to your animals]].

There are two different ways of re-packing: manually giving cargo animals the selected item to be carried or re-forming the caravan. The first alternative lets you make the most out of the area which may include mining, harvesting, and cooking, while the last option will instantly leave the place. Either way, before the countdown timer ends, all items must be put to be carried or they will be '''lost''' once the time runs out.

==== Visibility ====
{{Stub|section=1|reason=Needs actual equation defining visibility based on total body size}}
Visibility is how easy your Caravan is to notice. It multiplies the chance that your caravan will be waylaid by enemies. Visibility does not affect your ability to find things you want. Visibility is based on the total body size of all people and animals in the caravan. The default visibility for 1 person in a caravan is 20%, it does not scale linearly for additional people, as two people is 36%. You can see the visibility in the upper right while forming a caravan.

=== Ambush ===
Your caravan has been ambushed by an enemy faction. Colonists cannot exit the generated map until the attackers are defeated (killed, downed, or fled). If all are killed, the caravan is considered destroyed and will disappear along with any carried items.

</gallery>

# The game notifies you that an ambush is taking place, prompting you to check on your caravan.
# Pause the game to survey the enemy and position yourself by taking cover behind terrain features.
# Check where it's happening. As it is, in this case, right next to the colony, it's possible to quickly send reinforcements. However, you cannot send the backup caravan right into the battle, but must first move to an adjacent tile before joining your comrades.
# After an encounter ends, a 24-hour countdown begins so you can recover, pick up items, strip the dead/downed, and take care of any other need.
# To take prisoners, you should build the smallest room possible (remember you are on a countdown) which can just fit the same amount of sleeping spots for each downed enemy. Treat their wounds so they don't die while carrying them to your colony. Finally, reforming the caravan makes captives come with you (you will see them listed).
# Your prisoners are finally brought to your colony, but you see them wandering around (!!!). Don't worry as they won't attempt to escape. Your characters will proceed to unload their items. Eventually, wardens will come to pick them up and escort them to designated prison cells. Any incapacitated prisoners will remain downed and need to be carried.
If a hostile pawn that was downed gets up, the caravan will be unable to leave the map tile but the pawn won't be hostile.

==== Manhunter Ambush ====
Same as Ambush except with a manhunter pack of animals. Manhunters won't attempt to flee, and colonists can't either.

=== Demand ===
A number of pirates approach your caravan and demand that you give them items and/or hand over members as slaves. If you don't comply, they will proceed to assault the caravan. It's nearly always a better choice to fight back as pirates usually come in poor numbers.

=== Encounter ===
Another friendly caravan crosses paths with you, opening an opportunity to trade.

You can attack them if you wish, damaging faction relations. Your pawns may exit the map while engaging the caravan. Since you will be informed of their party composition but cannot clearly see who is in the caravan, you can decide if they're worth robbing.

Sometimes when attacking them, they may decide to do a 'bloody exit', that is to exit as aggressively as possible.

[[File:Caravan met peacefully.png|400px]]

=== Reform caravan ===
You can only reform caravans if there are no hostile pawns on the map or they are all either downed or asleep.

=== Caravan lost ===
If a caravan is lost, all items, animals, and prisoners become unrecoverable. A caravan is lost if all colonists die or suffer an irreversible [[mental break]] like Gone Wild or Give Up. Milder mental breaks which can be spontaneously snapped out of, like Sad Wandering, will not lose a caravan.

Colonists, animals, and prisoners can be banished via the 'Social' tab. Items carried by an abandoned pawn will be lost. Abandoning a caravan member will cause their friends and family to have sad thoughts, and if the colonist is unlikely to survive (such as in low temperatures), there will be a more severe penalty. Colonists who survive abandonment may eventually make their way back to your colony or return as part of an enemy raid or friendly caravan.

== Attacking other settlements ==
{{Rewrite|section=1|reason=Cleanup, potential size reduction, updating from A16 -> Present}}
{{Image wanted|section=1|reason=Shows bases from A16, they have significantly changed since.}}
You may raid other settlements on the world map, much like other factions do to your colony. To do this, all you need is to send a caravan to a site, and select the "Attack" interaction option. Attacking settlements gives you an opportunity to steal valuable goods such as [[glitterworld medicine]], [[luciferium]], [[component]]s, as well as weapons and armor.

* See [[Offense tactics|offense tactics]] for specific tips on how to assault outposts and bases.

=== Walkthrough ===
: The below shows bases from the Alpha 16 version of the game. Settlement defenders of later updates are ''significantly strengthened'' and are harder to defeat and are not scaled down by easier difficulty as other raids are.

== Version history ==
* [[Version/1.1.0|1.1.0]] - Changed caravan reform to be allowed with sleeping hostiles on site.
* [[Version/1.3.3066|1.3.3066]] - Caravan speed now solely depends on carried mass, ridden animals, and terrain movement difficulty. Pawn speed no longer impacts caravan speed. Some animals can be ridden by caravan members which boosts caravan speed. Downed pawns do not slow caravans down, but you still need at least one non-downed non-slave to operate the caravan. Fix: [[Psychoid leaves]], [[ambrosia]], [[smokeleaf leaves]] and [[hops]] can be selected as food for caravans.
* [[Version/1.3.3101|1.3.3101]] - Fix: It is possible to sell animals while forming a caravan.
* [[Version/1.4.3523|1.4.3523]] - Fix: When forming a caravan, downed pawns are sometimes left behind near the map edge. Fix: Pawns resting in caravans don't show the 'Z' icon on their portraits to indicate rest.
* [[Version/1.4.3525|1.4.3525]] - Fix: Clicking on the "carry pawn" checkbox in caravan screen opens health card.
* [[Version/1.4.3527|1.4.3527]] - Fix: Never sleep xenohumans still rest when caravanning alone.
* [[Version/1.4.3529|1.4.3529]] - Fix: [[Babies]] {{BiotechIcon}} can carry items in caravans.
* [[Version/1.4.3682|1.4.3682]] - Fix: Captured prisoners escaping from reformed caravans. Fix: Caravans holding relics cause "relic lost" thought on map exit.

{{TOCright}}
{{Rewrite|reason=Tone too guidelike and missing actual detail about combat not explained well elsewhere. melee verbs, damage types, etc should be explained conceptually here, and then further detail linked where appropriate.}}
RimWorld's combat system may seem a little daunting to new players at first, however a few simple guidelines will have you ready to repel attacks and hold ground like a pro.

In every gunfight there is one very important lifesaving rule to remember:<br/>
'''Always use whatever [[cover]] is available!'''<br/>

== Combat basics ==
[[Draft]] pawns to have them enter combat. While drafted, pawns with a ranged weapon will automatically fire at enemies they see. [[Wall]]s and other impassible objects will block line of fire. When adjacent to an enemy, pawns will always fight in melee - even if they are holding a gun. You can assign specific targets for both melee and ranged attackers.

There are several other key mechanics in the combat system of the game:

=== Cover ===
{{main|Cover}}
Using the strongest [[cover]] available is key to winning a firefight. Pawns will automatically use cover, like [[sandbag]]s and stone [[chunk]]s, that they are adjacent to. If you have the time and resources to spare, you can make multi-layer defenses, with rows of cover you can fall back to if you're being overwhelmed. The drawback is that, if enemies advance, they can use your defensive lines as cover.

[[Wall]]s are the best possible cover, shielding colonists from 75% of bullets. While they cannot be fired through, pawns will "lean" out from a wall and fire from its side. A row of 1-tile wide walls, interspersed with [[barricade]]s or [[sandbag]]s, are the strongest formation of cover.

Cover can also be used by your enemies. [[Chunk]]s of stone and steel slag are much more effective than [[tree]]s, and should be cleared out. Conversely, if assaulting a [[siege]] or [[mech cluster]] {{RoyaltyIcon}}, you should use any preexisting cover, such as chunks, [[ruins]], or [[mountain]]s.

=== Tactics ===
{{Main|Defense tactics}}
Sometimes you will have to use more clever tactics to defeat your incoming enemies, such as when you're outnumbered, or you don't have suitable ways to cope with the incoming raiders.

===Logistics===
During battle, it's often handy to keep colonists with [[firefighting]] duties nearby in case a [[fire]] breaks out. Pawns lit on fire will run around wildly, unable to attack. [[Firefoam pop pack]]s will extinguish colonists while preventing future fires. Even if someone is incapable of violence, they can help end fires nearby and rescue people in need.

After battle, you'll likely need to clean up and repair any damage done to your base. Undraft colonists so that they can start on work. Build [[grave]]s, set up a dumping stockpile accepting corpses, or use an [[electric crematorium]] to dispose of bodies, in order to avoid the mood penalty for seeing [[corpse]]s.

=== Pause frequently! ===
The most important combat tip is saved for last. Use the pause feature! The tide of battle changes very quickly with a smoking turret or thrown grenade in the middle of your colonists. Take advantage of the space bar to freeze the action and give your colonists new orders.

==Colonist management==
Ultimately, colonists are beings with [[mood]], [[need]]s, and [[injuries]] to take care of. A tired, hungry colonist will become progressively more upset, while [[pain]] isn't a particularly pleasant experience. [[Mental break]]s are absolutely ''lethal'' in combat, as the pawn will refuse to shoot or follow orders. To prevent this, you should ideally care for colonists ''before'' combat starts.

A pleasant base - great dining, recreation, and bedrooms specifically - will keep soldiers' spirits high. Alternatively, you can assign colonists to carry [[drug]]s at all times (Assign tab -> Drug policy). Order colonists to take the drug as combat begins. [[Go-juice]], while inherently addictive, confers major combat-related boosts.

===Skills===
As pawns can only hold one weapon at a time, colonists that are great at one combat stat (Shooting or Melee) are better than one decent at both. Shooting skill has a greater impact the further away a colonist is shooting from, so assign longer range weapons to skilled colonists. Give your best melee fighters the best melee weapons.

Ideally, you should keep your best doctors away from direct combat. In practice, having an extra shooter is more valuable - just don't be overly risky with them.

===Triage===
Tending to wounded colonists is important to save them from dying. Drafted colonists can immediately tend to others on the field, with or without medicine. Prioritize those who are bleeding out the most. While medicine does not staunch the flow of bleeding of a specific wound any faster, it can stop multiple wounds at the same time.

If a colonist starts to sustain too many injuries, you can use your less combat-skilled colonists to take over while they retreat. If need be, have your injured colonist drop their weapon and undraft them, then have your reserves pick up the weapon and fight in their place. If a pawn takes on too much damage, they may become [[downed]] and require rescue.

== Ranged ==
{{stub|section=1|reason= melee preventing ranged fire snd player exception}}
Ranged combat involves the use of weapons from a distance. Pawns wielding ranged weapons will shoot at enemies, because what else did you expect them to do?

Note that RimWorld does not have any ammo mechanics, even for items that visually appear to be finite, like [[pila]] and [[grenades]]. [[Doomsday rocket launcher]]s and [[triple rocket launcher]]s are consumed on use, while every other held weapon is infinite. Weapons will not be damaged so long as they are wielded, and weapon damage has no impact on their combat effectiveness.

===Weapon stats===
Ranged weapons consist of many attributes:
*'''Damage:''' How much health each bullet can do. For reference, the brain has 10 HP, the heart has 15 HP, and the torso (general body) has 40 HP.
*'''Armor penetration:''' The ability to ignore [[armor]]. AP directly subtracts from armor rating; if a weapon's AP > the armor %, then armor is completely ignored.
*'''Stopping power:''' The ability to stagger, or slow, pawns. A stopping power of 1 can stagger humans and human-like [[mechanoid]]s. When staggered, a pawn is reduced to 1/6th of their normal speed for {{ticks|95}}.
*'''Burst count:''' How many bullets are fired at a time. If a weapon fires multiple shots, there will be a short delay between bullets.
*'''Aim time''' and '''Cooldown time''': How long it takes between each burst. Aim time happens before shooting, cooldown happens after.
*'''Range:''' How far a weapon can shoot.
*'''Accuracy:''' A weapon's own modifier to accuracy. Shooting skill and other factors also determine accuracy.
** Each weapon has specific accuracy values at Touch (3), short (12), medium (25) and long (40) ranges. Linear interpolation is used for any values in between. (e.g. accuracy at 17.5 tiles is equal to the average of the short and medium accuracy)

There are two summary stats of how a weapon will actually perform:
*'''Optimal DPS:''' How much damage a weapon can do, per second, if every shot hits an unarmored target.
*'''DPS (Range):''' How much damage a weapon can do, per second, factoring in weapon accuracy at a specific range. (Before the shooter's accuracy, armor, etc.)
DPS is a measure of how fast a weapon can deal out [[pain]]. [[Pain shock]] is the primary way of disabling pawns in combat; hurt them enough, and they will be [[downed]]. Note that enemies downed from pain have a chance to [[death|die]], anyways. Other factors like range, stopping power, and aiming/cooldown time can all impact how you use a weapon in battle, but damage is a stat to be prioritized first.

===Effective accuracy===
Conventional (non-explosive) ranged weapon accuracy follows the following equation:
{| class="wikitable"
|-
| Accuracy = ([[Shooting Accuracy]]<sup>Range</sup> × Weapon Accuracy × Other factors
|}

In simpler terms:
*[[Shooting Accuracy]] is the stat of the shooter. A shooter's accuracy becomes exponentially more important the further a shot is fired. Higher Shooting skill, [[manipulation]], a [[gunlink]]{{RoyaltyIcon}}, etc. all improve this stat.
*Weapon accuracy is the stat of the weapon. Each weapon has specific accuracy values for shooting at specific ranges. This is a factor applied after shooting accuracy.
*Factors like [[cover]], [[smoke]], [[weather]], and body size are all multipliers or offsets to the "final" accuracy. See [[Weapons#Accuracy]] for the full list.

If a ranged weapon is calculated to hit, it will hit, regardless of where the bullet visually lands or any defender movement. If the bullet misses, then it can impact other tiles.

===Miss mechanics===
Whenever a regular ranged weapon misses, the projectile will land within a random distance from the original target depending on the actual accuracy of the shot based on the weapon and the shooter. Stray shots have a 50% chance of hitting nothing, and a 50% chance of hitting another target on the alternative cell it happens to land on. Projectiles can also hit other things that are between the target and the shooter, such as stray animals. Accuracy to maximum miss distances are as follows:

{| class="wikitable sortable"
! Accuracy !! Max Miss Distance !! Area (cells)
|-
| 100% || 1.0 || 5
|-
| 22% || 2.0 || 13
|-
| 11% || 4.0 || 41
|-
| 7% || 6.0 || -
|-
| 4% || 8.0 || -
|-
| 2% || 10.0 || -
|}

There are special mechanics in regards to [[friendly fire]], or hitting a pawn from the same faction.

===Forced miss===
{{Rewrite|section=1|reason=Added in 2018, verify this still works like this and if so then integrate with existing FMR weapon pages}}
Many weapons (mostly explosives) have a Forced Miss Radius stat. Forced miss is modified with distance:
{| class="wikitable sortable"
! Distance (cells) !! Radius Multiplier
|-
| 0 - 8 || 0
|-
| 9 - 24 || 0.5
|-
| 25 - 48 || 0.8
|-
| 49+ || 1.0
|}

Weapons with this stat will ''always'' land within their forced miss radius, ignoring every factor to accuracy. There is a small chance to use standard accuracy instead, more likely with a small radius.

== Melee ==
[[File:Melee_test_eleplants_block.png|thumb|200px|left|A very basic melee block, available in any doorway.]]
Melee involves hand-to-hand combat, with or without the use of weapons. Accuracy is determined with the [[Melee Hit Chance]] stat.

Pawns will usually not stack into a cell with other melee attackers. For enemies, only one pawn per cell can attack the same target. Undrafted colony brawlers will not always have collision, so it is possible for them to stack if the [[Threat response|threat response setting]] is set to attack.

Melee combat has strengths and weaknesses. While a pawn can bash with a gun barrel in melee, a fighter with a dedicated melee weapon remains much more effective. However, a brawler may get shot down during their approach. The [[shield belt]] was designed to solve that problem. A colony might develop a [[Defense tactics#Melee sortie|small strike team of brawlers]] that can swiftly eliminate threats in close quarters, especially those that have infiltrated the colony.

One of the most common tactics is the ''[[Defense_tactics#Melee_blocking|melee block]]'' (see left). Stand 3 colonists just outside a hallway or door entrance. This ensures that you only fight 1 enemy at a time, reducing their relative damage output. Other colonists can fire behind the melee blockers, though enemy raiders can fire behind each other too. Effective against [[infestation]]s and melee rushes.
{{clear}}
===Other mechanics===
{{Stub|section=1|reason=kick in eyes detail. how often is it selected, how dooes it interact with the verb system, cooldown timme - booth beforenit can benused again and if replacong an attack melee cooldown, inter linking - [[terrain]] table, terrain pages, hediff pages, [[sight]] etc}}
* Skilled melee pawns have the ability to evade melee attacks when fighting. When the melee blow is dodged, it will always miss, regardless of whether or not it is supposed to hit.
* Blunt melee attacks don't cause bleeding (unless a body part is destroyed), but they have a chance to stun enemies for a short time on hit. In addition, most pieces of [[armor]] will protect poorly against blunt attacks.
* Pawns that engage in melee combat while standing on dirt may 'kick dirt' or 'water' in their target's eyes, effectively blinding them for a short time (-80% [[sight]] for dirt, and -50% sight for water).

== Friendly fire ==
{{stub|section=1|reason=this is two of the quoted several subsidiary mechanics, more detail is needed}}
[[File:Friendly Fire Radii.png|thumb|right|Friendly fire safety radii:<br>Central pawn will not hit any friendly pawn on or within the gold radius<br>Any pawn on a sterile tile will not hit any other friendly pawn on a sterile tile.]]
Friendly fire is a mechanic in which ranged attacks that missed their target have chance to hit nearby targets, including allies. As such it is important to be careful when you shoot at enemies while allies are in the way or near them, as they may have a chance of being hit as well.

There are several subsidiary mechanics in this process.

First, there is a safe zone around the shooter in which allies cannot be hit by friendly fire at all. Colonists can always shoot over the shoulders of allies up to 5 tiles away from them, but any further and allies may be hit. This range is represented by the gold and sterile tiles in the image to the right. The inner radius of sterile tiles defines an area in which a group of pawns cannot friendly fire each other. The safe zone applies even if the target is within the zone.

Second is the [[AI_Storytellers#General|Friendly Fire Difficulty Setting]]. This acts as chance multiplier on the existing chance of friendly fire, ranging between 0% and 100% to pawns in the red area of the image or beyond. Note that 100% will not result in all misses causing friendly fire, it only adds an additional scalar to the existing chance.

== Combat log ==
The game keeps track of all combat actions done by a pawn. This can be accessed through the 'Log' tab for a character, and lets you review combat after the battle has finished or in the heat of it.

Each action is accompanied by some flavor text.

== See also ==
*[[Defense tactics]] for a more in-depth guide about countering hostile events
*[[Defense structures]] for building defenses in your colony
*[[Offense tactics]] for assaults on hostiles outside your colony
*[[Weapon Guide]] for ways to use or counter different kinds of weapon

== Version history ==
* [[Version/0.18.1722|0.18.1722]] - Storyful combat: A major rework of melee combat, and a new way to report all combat interactions. Storyful combat generates a combat log that reports each blow, miss, swipe, block and fall in the combat. During or after a fight, you can review the combat log to see what happened, to generate a richer story.

These devices are capable of physical and psychic feats which seem impossible to human scientists. As with all archotechnology, no human can create one. We can only try to scavenge the ones that archotechs create for their own unfathomable reasons.<br/>This capsule is useless by itself, but it can be spent at a gene assembler to create a new archite-powered xenogerm. This requires researching archogenetics and a genepack that contains an archite gene. Archite genepacks can be obtained from traders.

'''Archite capsules''' are exotic resources that are spent when adding [[Genes#Archite|archite genes]] to a [[xenogerm]].

== Acquisition ==
Like all [[Lore#Tech_levels|archotechnology]], archite capsules cannot be crafted. Instead, they can only be acquired through [[trade]] with tradeships, caravans, and [[faction base]]s, or as a reward for performing [[quests]]. Orbital Exotic goods traders will always carry 1 to 2. Exotic Good caravans have a 10% chance to stock 1.

| 50% chance of 1<br>50% chance of 2<br>
|}

== Summary ==
Archite capsules are necessary for applying [[Genes#Archite|archite genes]] to a [[xenogerm]]. These genes each have an archite capsule cost, denoted by the [[File:Archite capsule required.png|16px|Archite Capsules]] symbol. Archite capsules will be loaded into the [[gene assembler]] before recombination begins, and will be consumed by the process.

In order for the archite capsule to be used by the gene assembler, make sure to have a genepack with archite metabolism requirements. Then have the archite capsules put into the same room as the gene assembler with a stockpile zone for the capsules. The gene assembler will then recognize the archite capsules and use them when you make your genepack. One of the colonists will load the gene assembler with the archite capsules and your main research colonist will make the progress time move faster.

Archite capsules are safe from deterioration, and cannot be burned. However, they can still be stolen, smashed, or blown up.

== Analysis ==

Archite capsules are largely common when it comes to buying them from traders and settlements, meaning that you don't need to buy them early and keep them until the research is done: You can wait and spend silver on more useful early game items. Archite genes are extremely powerful, but are largely combat pawn based, with [[Scarless]] meaning fewer permanent injuries, [[Deathless]] can allow pawns to become almost invincible (since they can only be downed most of the time), and [[Perfect immunity]] meaning they cannot get infections and will not die from regular illness. Non-combatant pawns can also be greatly improved by using [[Archite metabolism]], or by giving them good genes such as Perfect immunity. [[Ageless]] and [[Non-senescent]] can be put onto older pawns, meaning that they will not develop age-related diseases which can help them last longer. [[Gene implanter]] allows you to duplicate expensive genomes with a long cooldown, so it mostly will act as a supplement if you want to give the genome to a lot of colonists.

'''Barricades''' can be placed to provide pawns [[cover]], sheltering them from gunfire.

== Acquisition ==
{{Acquisition}}

== Summary ==
{{See also|Sandbags}}
Barricades provide {{%|{{P|Cover Effectiveness}}}} [[cover]] effectiveness, meaning that bullets aimed at targets behind barricades have a {{%|{{P|Cover Effectiveness}}}} chance to hit the barricades, leaving only a {{%|1-{{P|Cover Effectiveness}}}} chance to hit anything behind them. Cover won't shelter pawns from melee attacks, thrown projectiles, or explosions. Both colonists and [[raider|enemies]] benefit from cover, as do [[turrets]]. They provide identical cover to [[sandbag]]s.

Barricades are placed on the ground. They slow down pawns walking over them, and do not allow a pawn to "stop" to fire or take cover if they are standing on one.
They take damage from bullets and explosions.

Barricades are largely interchangeable with [[sandbag]]s, as they both have identical [[cover]], base {{HP}}, and similar material costs. However, sandbags are made of [[textile]]s and are always nonflammable, while barricades are made of [[metal]], [[wood]], and [[stone]] materials and their flammability depends on the material chosen. Sandbags also require much less work to make, but barricades are somewhat more [[beauty|beautiful]]. Unlike sandbags, barricades will also enclose a [[pen]], similar to the [[fence]].

== Analysis ==
{{Rewrite|section=1|reason= 1.6 now allows enemy pawns to stand and fire on top of sandbags and barricades. Their usefulness in killboxes needs to be reevaluated.}}
Barricades and sandbags are, in most respects, identical. The material affects the building's health, but not its defensive properties. Barricades are easier to build in the early game, where access to [[textile]]s in bulk quantities is difficult. As they are slightly more beautiful, but require more work to make, they are marginally better at permanent defenses, while sandbags are better when attacking. Just remember that [[raiders]] will use cover to the same effect, so deconstruct unneeded buildings when you can.

Either building can be combined with [[wall]]s for more cover. Walls provide superior cover, but a full wall will block line of fire. Having a wall with a 1-2 tile gap of barricades will give more cover than simply using barricades, while still allowing pawns to fire through.

Sandbags and Barricades can no longer be used to prevent enemies from standing in a specific position. Previously, in patch 1.5 and earlier, barricades and sandbags and some other similar objects were used to prevent enemies from taking cover on a wall. Enemies can now stop and fire while standing on any object. Barricades, Sandbags and others can still be somewhat effective in causing enemies to path around a position of cover. However, if the enemy does path to that cell with the barricade, sandbag or any other object, they can always fire.

== Material table ==
As barricades and [[sandbags]] are largely interchangeable except for their aesthetics and material properties, both are included in the following table for convenience.

Note that cover effectiveness is {{%|{{P|Cover Effectiveness}}}} regardless of material or structure choice.

MortalSmurph: /* Room Cleanliness Multiplier */

{{Verified|1.3.3101}}{{Stat
| default base value = 1
| min value = 0
| to string style = PercentZero
| description = A multiplier to the chance that a surgery will succeed when performed here. Surgery success chances are also affected by many other factors, including the surgeon's ability and medicine used.
| category = Building
}} This stat is applied to beds and other [[sleep furniture]].

* Note that this stat is specific to the base '''Surgery Success Chance Factor''' of a given ''type'' of sleep furniture.

* When placed in-world, the '''Surgery Success Chance Factor''' of a specific ''item'' of sleep furniture changes. It is additionally weighted by [[#Environmental factors|environmental factors]].

In other words, "Surgery Success Chance Factor" is the stat of the ''bed item'' and its location.
* For the surgery success stat of a specific ''[[colonist]]'', see [[Medical Surgery Success Chance]].
* For the "true" chance of a surgery succeeding, where this factor is one part of the equation, see [[Surgery]].

== Formula ==
When placed in-world, the specific ''item'' of [[Sleep furniture]] has its '''Surgery Success Chance Factor''' stat adjusted based on its environment.

This is calculated as:

{| {{STDT|}}
| '''Surgery Success Chance Factor<sub>''item''</sub>''' = ([[#Base stat|Base stat]]<sub>''type''</sub> + [[#Facility Offset|Facility Offset]]) × [[#Room Cleanliness Multiplier|Room Cleanliness Multiplier]] × [[#Light Multiplier|Light Multiplier]] × [[#Outdoors Multiplier|Outdoors Multiplier]] × [[#Quality Multiplier|Quality Multiplier]]
|}

=== Base stat ===
Every type of [[Sleep furniture|sleep furniture]]'s '''Surgery Success Chance Factor''' has a base value stat assigned as follows.
{{#ask:
[[Category:Sleep furniture]]
|mainlabel=Sleep furniture type
|?Surgery Success Chance Factor=Surgery Success Chance Factor
}}

=== Facility Offset ===
In addition, ''facilities'' placed adjacent to the head of the item of sleep furniture can adjust the stat of the placed item.

The result of these additional factors are displayed under the '''Facilities''' heading within the '''Stats''' tab of the information page.

{| {{STDT|}}
! Facility Type !! Offset
|-
| [[Vitals monitor]] || {{+|0.05}}
|}

=== Room Cleanliness Multiplier ===
The room cleanliness factor for performing surgery is a determined by the value displayed on the [[Rooms#Cleanliness|room's cleanliness]] by the following curve:

{| class="wikitable" style="text-align:right"
! Room<br/>cleanliness !! Room<br/>Cleanliness<br/>Multiplier !! Graph
|-
| -5 || 0.6
| rowspan="4" | {{Graph:Chart| width = 200 | height = 200 | type = line | xAxisTitle = Room cleanliness | yAxisTitle = Room Cleanliness Multiplier | x = -5, 0, 5 | y = 0.6, 1, 1.15 | xAxisMin = -5 | yAxisMin = 0.6 | yAxisMax = 1.15}}
|-
| 0 || 1
|-
| 1 || 1.1
|-
| 5 || 1.15
|}

This can be translated into the following formulas:
{| {{STDT|}}
! Range !! Formula
|-
| Room cleanliness < 0 || '''''Room Cleanliness Multiplier''''' = 1 + [[Rooms#Cleanliness|Room cleanliness]] × 0.08
|-
| Room cleanliness > 0 || '''''Room Cleanliness Multiplier''''' = 1 + [[Rooms#Cleanliness|Room cleanliness]] × 0.03
|}

The value is limited to a minimum of {{Bad|0.6}} for -5 cleanliness and a theoretical maximum of {{Good|1.15}} for 5 cleanliness, which is practical limited to {{Good| {{#expr:1+ {{Q|Sterile tile|Cleanliness}}*0.03}} }} by the highest available cleanliness of {{Q|Sterile tile|Cleanliness}} of the [[sterile tile]].

If the surgery is performed outside (i.e. not in a room at all), the cleanliness factor is treated as the minimum ({{Bad|0.6}}).

=== Light Multiplier ===
Extremely low levels of [[Environment#Light|light]] negatively affect the resulting value.

In complete darkness, this can be as little as {{Bad|0.75}}. At 50% light level and above, a factor of {{Good|1}} is applied.

This is referred to as '''Multiplier for light''' within the '''Stats''' tab of the information page.

{| {{STDT|}}
| '''''Multiplier for Light''''' = 0.75 + [[Environment#Light|Light Level]] × 0.5
|}

=== Outdoors Multiplier ===
If the item of sleep furniture is placed performed [[outdoors]] (i.e. there is no room of which the cleanliness may be assessed), an additional multiplier of {{Bad|0.85}} is applied to the resulting chance of surgery success.
{| {{STDT|}}
! Environment Type !! Multiplier
|-
| Indoors || '''1'''
|-
| Outdoors || {{Bad|0.85}}

=== Quality Factor ===
A multiplier based on the [[quality]] of the specific item is applied. This is referred to as the '''Quality Multiplier''' within the '''Stats''' tab of the information page.

{| {{STDT|}}
! Quality !! Multiplier
|-
| Awful || {{Bad|0.9}}

=== Facility Offset ===
In addition, ''facilities'' placed adjacent to the head of the item of sleep furniture can adjust the stat of the placed item.

The result of these additional factors are displayed under the '''Facilities''' heading within the '''Stats''' tab of the information page.

=== Room Cleanliness Multiplier ===
The room cleanliness factor for performing surgery is a determined by the value displayed on the [[Rooms#Cleanliness|room's cleanliness]] by the following curve:

{| class="wikitable" style="text-align:right"
! Room<br/>cleanliness !! Room<br/>Cleanliness<br/>Multiplier !! Graph
|-
| -5 || 0.6
| rowspan="3" | {{Graph:Chart| width = 200 | height = 200 | type = line | xAxisTitle = Room cleanliness | yAxisTitle = Room Cleanliness Multiplier | x = -5, 0, 5 | y = 0.6, 1, 1.15 | xAxisMin = -5 | yAxisMin = 0.6 | yAxisMax = 1.15}}
|-
| 0 || 1
|-
| 1 || 1.1
|-
| 5 || 1.15
|}

This can be translated into the following formulas:
{| {{STDT|}}
! Range !! Formula
|-
| Room cleanliness < 0 || '''''Room Cleanliness Multiplier''''' = 1 + [[Rooms#Cleanliness|Room cleanliness]] × 0.08
|-
| Room cleanliness > 0 || '''''Room Cleanliness Multiplier''''' = 1 + [[Rooms#Cleanliness|Room cleanliness]] × 0.03
|}

The value is limited to a minimum of {{Bad|0.6}} for -5 cleanliness and a theoretical maximum of {{Good|1.15}} for 5 cleanliness, which is practical limited to {{Good| {{#expr:1+ {{Q|Sterile tile|Cleanliness}}*0.03}} }} by the highest available cleanliness of {{Q|Sterile tile|Cleanliness}} of the [[sterile tile]].

If the surgery is performed outside (i.e. not in a room at all), the cleanliness factor is treated as the minimum ({{Bad|0.6}}).

=== Light Multiplier ===
Extremely low levels of [[Environment#Light|light]] negatively affect the resulting value.

In complete darkness, this can be as little as {{Bad|0.75}}. At 50% light level and above, a factor of {{Good|1}} is applied.

This is referred to as '''Multiplier for light''' within the '''Stats''' tab of the information page.

{| {{STDT|}}
| '''''Multiplier for Light''''' = 0.75 + [[Environment#Light|Light Level]] × 0.5

=== Outdoors Multiplier ===
If the item of sleep furniture is placed performed [[outdoors]] (i.e. there is no room of which the cleanliness may be assessed), an additional multiplier of {{Bad|0.85}} is applied to the resulting chance of surgery success.

Infestation

2025-10-21T03:37:10Z

MortalSmurph: /* Planned Infestations */ dirty is not a factor

'''Infestations''' are an [[event]] and a serious threat in which a number of [[hive]]s are spawned, alongside [[insectoid]] defenders. They can happen randomly in your colony and [[Quests#Ancient_Complex|ancient complexes]] or can be caused by a [[quest]]; quests will warn you if this is an outcome. Infestations can be very destructive, but leave behind valuable [[insect jelly]] and opens the opportunity for insect farming.

== Natural Infestations ==
{{Rewrite|section=1|reason=Broadest to narrowest information style. Reduce verbosity}}
{{Stub|section=1|reason=protection of expansion rate with examples}}
[[File:PSA INFESTATIONS.PNG|350px|thumb|right|Blue squares show an area with a chance of infestations spawning.]]
[[File:PSA INFESTATIONS_2.PNG|225px|thumb|right|Making 1x1 squares will usually eliminate bugs.<br>But if a 1x2 area has a ''single'' mountain roof - regardless if the other tile is mountain or not - then it can spawn infestations.]]
Natural infestations occur at a maximum of once every 20 days, but generally less often than raids, and only with a valid location.<ref name="RaidPoints">Incidents_Map_Threats.xml. Min refire days 20. Base Chance 2.7. Min Threat Points 400</ref>. Natural infestations require an area larger than 1x1, within 30 tiles of a colony [[structure]], with at least one [[overhead mountain]] roof. They start from a single "valid" tile, which must have a temperature higher than {{Temperature|-17}}. Temperatures under {{Temperature|-8}} will gradually reduce the spawn chances in that area. Infestations can appear from any valid tile, but tend to prefer areas that are very deep underground, dark, and far from unroofed cells.

Infestations in [[Quests#Ancient_Complex|ancient complexes]] will emerge after entering certain rooms but are usually smaller than a comparable colony hive and easier to defeat, avoid or redirect.

If generated from a [[quest]] with no valid location, infestations may spawn outside in the open.

[[Hive]]s and [[insectoid]]s will spawn within a given radius, regardless of whether those tiles are valid. A hive does not have to spawn on an infestation's center point. The initial size of an infestation is based on [[raid points]], so infestations will get bigger as the game progresses.<ref name="RaidPoints"/> If the size of the event is larger than the "valid" space, it will happily expand to appear in nearby "invalid" areas, even if those areas are not directly connected. Infestations will stop expanding at a size of 30 hives or above, but letting infestations grow at all is usually inadvisable.

Defeating an infestation with hives grants a {{+|4}} ''Defeated insect hive'' [[mood]] buff to all pawns on the map. This buff lasts 10 days and stacks up to 5 times.

=== Behavior ===
[[File:Insectoid hive aggro range.png|300px|thumb|left|Range at which insects will defend a hive]]
[[Insectoids]] ([[Megascarab]]s, [[Megaspider]]s and [[Spelopede]]s) will spawn near hives and spend their time roaming around them. They will attack and chase any intruder that comes within a 10-tile circular radius from the hive that spawned them, returning to their hives once the threat is gone. Insectoids will only attack creatures they can see, and will not attack while they are sleeping, provided they are not woken up.

They will randomly dig at stone and structures while wandering around their hives, potentially breaching into new areas.

If any of the insectoids are downed or damaged, the entire infestation will go after colonists on the map, attacking and breaking down structures in the process. Even if outside [[raider]]s or other factors (like hypothermic slowdown) down them, they will be aggressive. If insectoids don't see hostiles within 100 tiles, they will give up and return to their hives.

If the hives and insectoid colony are left intact, they will reproduce, progressively growing more numerous. If all megaspiders or spelopedes are killed, the hive(s) will start deteriorating due to lack of maintenance but will most likely replenish them before it's destroyed.
{{clear}}

==Other infestations==
These events are called "infestations", but do not generate [[hive]]s, meaning they do not share the behavior as shown above. They are immediately hostile to colonists and will attack like [[raider]]s do.

===Too Deep: Infestation===
Insectoid infestations can spawn from the use of a [[deep drill]]. Insectoids, but not hives, will pop out around the drill's area. These do not have the overhead mountain requirement like regular infestations. However, they are often smaller in number, and are unable to reproduce due to the lack of hive.

===Wastepack infestations===
{{Biotech|section=1}}
{{Main|Wastepack infestation}}
Wastepack infestations may appear whenever [[toxic wastepack]]s are destroyed.

When a wastepack infestation triggers, it creates [[stasis cocoon]]s. When these cocoons are disturbed, or when a human walks within a set radius, the insects will appear. Wastepack infestations are more aggressive, attacking any hostiles, buildings, random junk and even wild animals they encounter.

== Strategies ==
{{Rewrite|section=1|reason=Strategy style formatting, easiest first. Split tactics. Conciseness}}
{{See also|Defense tactics#Infestations}}

Infestations are most threatening in mountain bases, as they can spawn practically anywhere inside your base. Outside a mountain, they are much less harmful - around a normal level threat. When fighting an infestation, always ensure you ''completely annihilate every hive''. If even one is left, insectoids can keep spawning and leave you back where you started.

Since insectoids do not attack creatures while sleeping, it is possible to haul materials in and out of the area near their nests at night, including flammable material. This is however extremely risky, since attacking one of them, or doing construction near the insectoids, will wake them up. They also wake up when their individual need for rest has been filled, so be prepared (with all relevant items staged in a nearby stockpile) and act quickly once they're asleep.

=== Prevention ===
==== Wall filling ====
Hives require overhead mountain tiles to spawn naturally. Open caves and previous infestation locations can be walled in to move spawns away from your most important base areas, as long as they're not mountainous.
As they require more than 1x1 of overhead mountain, you only need to build walls every second square. Only walls are capable of stopping infestations; columns and doors do not work. Note that an overhead mountain square next to an open "thin roof" area is also a valid spawn point.

==== Freezing ====
Because mountains are naturally well insulated and more stable in temperature, freezing your base is a potential, though fragile, strategy of protecting mountain bases in most biomes. By reducing the temperature of every tile of overhead mountain to {{Temperature|-17}}, spawning can be prevented, however outside of the coldest biomes, this requires [[cooler]]s and a significant amount of power. A [[solar flare]], [[EMI dynamo]], or similar can leave you open to infestations, so adequate defences are still recommended. The cold will also affect work speed, pawn moods, and potentially pawn health.

When spawn proofing a base, be thorough - even a single warm tile can cause a full infestation. If there is ''any'' valid tile, infestations can spread nearby into seemingly safe areas, even if there is a wall many tiles thick between.

===Melee block===
[[File:Grenades melee block.png|200px|thumb|right|[[Melee block]] with [[frag grenade]]s. Grenades not necessary.]]
With a few, well-armored melee colonists, insects can be very simple to deal with via a [[melee block]] tactic.

[[File:Melee_block_door.png|150px|thumb|left|When designing a mountain base, keep these 6 tiles unblocked.]]
Use a chokepoint, such as in any [[door]]way. Have 3 melee colonists behind the chokepoint, and any amount of ranged fighters behind them. If done correctly (see right), you should have 3 colonists fight 1 insect at a time. As insects are only melee enemies, this is a trivial way to dispatch of insects. Frag grenades are extremely effective, but are not required.

When designing a mountain base, you will want to create many chokepoints where you can melee block. You do not want to block colonists from standing on the 3 tiles behind the doorway, so place buildings away from the doorway. (See left)

===Kiting===
If insects spawn "in the open" (i.e. not inside a mountain), then [[kiting]] tactics are effective.

Even [[megascarab]]s, the fastest insect, are {{%|{{#expr:{{Q|Megascarab|Move Speed Base}} / {{Q|Human|Move Speed Base}} round 2}}}} as fast as a healthy baseline human (assuming no Pollution Stimulus). So it is possible to lure the insects, shoot with a ranged weapon, and retreat. After you get to a safe distance, have colonists shoot, and retreat again, repeating until all insects are killed. This strategy works well against Too Deep: Infestations, as well as any hive outside of your base.

=== Mitigation ===
==== Damage prevention ====
Keep expensive or complex production buildings in multiple locations, or seal them off with small compartments only large enough to contain the workbenches and associated facilities alone. Have multiple access points for rooms deep inside mountains so that colonists aren't trapped behind infestations.

==== Planned Infestations ====
[[File:Planned infestation.jpg|300px|thumb|right|An infestation spawn point trapped with incendiary IEDs, surrounded by stone walls and doors.]]

Insects are more likely to spawn in darkness, in "warm enough" temperatures, above -8°C (17.6°F).
If you are able to ensure that there is only one valid infestation location on your base map, you can prepare this area to automatically trap and kill the insects with fire when they appear.

In a mountain base, you can create a "lure room". This will be a massive room that is warm, unlit, ''very'' far away from your proper base. Since there will be many more valid tiles to spawn inside this room, infestations will most likely spawn there. You can then light this room on fire - see below for details.

===Fire===
One way of dealing with infestations is with [[fire]]. This consists of 2 parts:
# Have a "lure" room - see above for details. In an outdoors base, it is likely that only 1-2 rooms have overhead mountain, meaning dedicated rooms can be built.
# Light it on fire. Fill it with flammable objects like [[barricade]]s and [[wood floor]]. You can either use [[molotov cocktail]]s or [[IED incendiary trap]]s to do the work.
Insects should die of [[heatstroke]] before they breach through 2-3 layers of door.

It is important to note that [[temperature]] is usually what kills insects, not the fire itself. Throwing molotovs outdoors is unlikely to be helpful: insects can walk past a burning [[wood floor]] with minimal damage, and even a direct molotov hit doesn't do much damage. Rather, it is the >{{Temperature|300}} heat that ignites the entire infestation and causes lethal levels of [[heatstroke]]. More gradual heatstroke will kill the bugs more slowly, but with less damage and anger from bugs compared to continuous burns. An area must be "[[indoors]]" in order to receive any sort of temperature change.

===Insect AI===
When attacked, insectoids will go after colonists without any walls between them first. This allows the insectoids to be lured away from their hives, chasing a runner colonist across the map. While they are away the hives can be destroyed. As long as hives are being damaged, the insectoids will keep chasing after colonists instead of returning to their hives. To keep the hive destroying pawns safe from having the insectoids' attention turned to them rather than the runner, a wall can first be built to block off the insectoids from the hives. Note that some new insectoids are likely to spawn at the hives during the process. Once all the hives are destroyed, the insectoids will wander the map like normal animals and soon starve to death.{{Check Tag|Detail needed|Actual behavior from defs?}}

=== Farming ===
{{See also|Hive#Farming}}
Insect hives in well defended and sufficiently distant colonies can be farmed for large amounts of insect jelly. At high difficulty levels, spawned insects also give large amounts of insect meat. <ref name="RaidPoints"/>

An infestation event is considered active until all spawned hives are destroyed, with ongoing infestations preventing new ones from occurring.<ref> Future incidents chances reduced to zero, unknown file ref </ref> If you can lure an infestation away from your colony into areas your colonists are prevented from accessing, you can prevent random infestations from occurring everywhere in your base, at the cost of a much more dangerous number of insects as it continues to grow.

However, infestations can also be limited in growth by removing suitable locations for new hives to expand into. Insects will dig through rocks and most structures{{Check Tag|Detail needed|Unclaimed structures included? fences?}}, but will not expand new hives into spaces that are too far from their existing nests or unroofed. [[Ancient_shrine|Ancient dangers]] can be potentially used for both finding a "decoy" hive, and limiting their available space, if you can distract the hostile bugs long enough to expose the majority of their nesting space to the sky. Smaller mountains may work as well, as bugs will almost always leave [[collapsed rocks]] alone for their own safety. Bugs in these circumstances should be given plenty of space to avoid encounters and walled off for the safety of travelers, and for the bugs themselves against more dangerous raids.

MortalSmurph: /* Violence */ Updated kind description

{{Biotech}}
{{Recode|reason=Thought templates}}
{{See also|altphrase=This page is a list of genes. For a full explanation of the gene system see|Genetics}}
'''Genes''' are a system for adding capabilities to [[human]] pawns. They can be obtained from character creation or implanted via [[xenogerm]].

Metabolic efficiency, denoted by the [[File:Metabolism.png|20px|Metabolism]] symbol, controls the rate at which pawns get [[Saturation|hungry]]. Harmful genes will increase their metabolic efficiency, getting hungry slower, and thus consuming less food overall. Meanwhile helpful genes reduce metabolic efficiency, getting hungry faster, and thus consuming more food. A baseline human has a metabolic efficiency of 0 (100% hunger rate), and genes can bring it as low as -5 (225% hunger rate) or up to 5 (50% hunger rate). The game prevents you from giving pawns less than -5 metabolic efficiency; it doesn't stop you from exceeding 5, but hunger rate will not go below 50%.

Note that genes with over [[File:Metabolism.png|20px|Metabolism]] 5 cannot be extracted by themselves, and must be extracted in a pack with another gene that lowers metabolism cost.

Complexity, denoted by the [[File:Complexity.png|20px|Complexity]] symbol, affects how many [[gene processor]]s you need to create a [[xenogerm]] from a set of genes. A [[gene assembler]] can create xenogerms with a maximum complexity of 6, plus 2 for every attached gene processor. Complexity also determines the base time it takes to create the xenogerm, ranging from 4 hours at ≤3 complexity, to 23 hours at ≥20 complexity (which is then scaled by the [[research speed]] of whoever operates the gene assembler).

The type of gene is shown both by its position in the gene tab of the pawn and its background:
* [[File:GeneBackground Endogene.png|32px]] Germline Genes
* [[File:GeneBackground_Xenogene.png|32px]] Xenogenes
* [[File:GeneBackground ArchiteGene.png|32px]] Archite genes

== Work Required ==
The work required to create a xenogerm is determined by its [[File:Complexity.png|20px|Complexity]]. First, a base value is obtained from the post-process curve with the points:

! Extra pain<br>[[File:Gene_ExtraPain.png|64px]]
| Carriers of this gene feel more pain than others given the same injuries. Neuron activity in the brain's nociception center is amplified, so pain feels extra-intense and fiery. This can be protective, but overall it's considered a negative and makes it hard to push through difficult situations.

|- id="Reduced pain"

| Carriers of this gene feel half as much pain compared to a baseliner. Reduced neuron activity in the brain's nociception centers makes pain dull and faint. This can be advantageous sometimes, and dangerous other times.

=== Body type ===
Since people without these genes can have any of the four body types, these genes effectively limit what body types a xenotype can have. For example, [[File:Neanderthal.png|20px|link=Neanderthals]][[Neanderthals]] cannot be thin, because they have all three of the other genes.

=== Melanin ===

These natural skin colors are '''not available in the xenotype editor and cannot be extracted'''. Every person gets one of these as a germline gene unless they already have a skin-color germline gene (e.g. [[File:Dirtmole.png|20px|link=Dirtmoles]][[Dirtmoles]] have light gray skin instead of these).

These genes are defined in Core, not Biotech. They are all named "Skin color" in-game.

=== Skin ===
These exotic (non-natural) skin colors do not appear on anyone without the gene. Like body type genes and hair genes, a person can have more than one skin color gene (e.g. [[File:Impid.png|20px|link=Impids]][[Impids]] have three), and one will be chosen.

All of these genes have a "random brightness factor" of 0.18 unless otherwise specified.

== Notes ==
* Certain genes will not be properly negated by other genes. For example, a drug dependency germline gene, while appearing to be negated by the same drug dependency as a xenogene, will instead cause the negative mood from the lack of the drug to start at 2.5 days instead of at 5 days.

== Version history ==
* [[Biotech DLC]] Release - Added.
* [[Version/1.4.3524|1.4.3524]] - Children no longer get adult body types from genes.
* [[Version/1.4.3525|1.4.3525]] - Fix: Suppressed genes contributing to romance chance still apply. Fix: Attempting to absorb a xenogerm of your own colonist displays a warning message saying you'll anger your faction.

* [[Version/1.4.3555|1.4.3555]] -
** [[#Psychic bonding|Psychic bond]] now gives +10% [[psychic sensitivity]], or +5% if on different maps. Hediff description changed from ''This person has a psychic bond with another person based on the psychic bonding gene.'' to ''This person has a psychic bond with another person based on the psychic bonding gene. The bond itself grants some limited psychic awareness, allowing it to connect even with the psychically deaf''. Bonds can now be created during lovin' allowing pawns already in a relationship when the gene was implanted to bond.
**Many genes now give direct boosts instead of forcing traits, which allows genes and traits to stack:
*** '''Depressive''' gene renamed to [[#Very unhappy|Very unhappy]], no longer forces [[Depressive]] trait instead decreases mood by {{--|10}}. '''Pessimist''' gene renamed to [[#Unhappy|Unhappy]], no longer forces [[Pessimist]] trait instead decreases mood by {{--|5}}. '''Optimist''' gene renamed to [[#Happy|Happy]], no longer forces [[Optimist]] trait instead increases mood by {{+|5}}. '''Sanguine''' gene renamed to [[#Very happy|Very happy]], no longer forces [[Sanguine]] trait instead increases mood by {{+|10}}.
*** [[#Slow runner|Slow runner]] no longer forces [[Slowpoke]] trait instead decreases move speed by {{--|0.2}} {{CS}}. [[#Fast runner|Fast runner]] no longer forces [[Fast walker]] trait instead increases move speed by {{+|0.2}} {{CS}}. [[#Very fast runner|Very fast runner]] no longer forces [[Jogger]] trait instead increases move speed by {{+|0.4}} {{CS}}.
***'''Slow learner''' renamed to [[#Slow study|Slow study]], no longer forces [[Slow learner]] trait instead multiplies [[Global Learning Factor]] {{Bad|×50%}}. '''Fast learner''' renamed to [[#Quick study|Quick study]], no longer forces [[Fast learner]] trait instead increases [[Global Learning Factor]] {{+|50%}}.
*** '''Staggeringly ugly''' gene renamed to [[#Very unattractive|Very unattractive]], no longer forces [[Staggeringly ugly]] trait instead decreases beauty by {{--|2}}. '''Ugly''' gene renamed to [[#Unattractive|Unattractive]], no longer forces [[Ugly]] trait instead decreases beauty by {{--|1}}. '''Pretty''' gene renamed to [[#Attractive|Attractive]], no longer forces [[Pretty]] trait instead increase beauty by {{+|1}}. '''Beautiful''' gene renamed to [[#Very attractive|Very attractive]], no longer forces [[Beautiful]] trait instead increase beauty by {{+|2}}.
** '''<Drug> addict-resist''' genes renamed to [[#Alcohol resistant|<Drug> resistant]], Addiction-resistant genes for alcohol, smokeleaf and psychite provide a 50% reduction in tolerance buildup. Addiction-resistant genes for psychite, wake-up and go juice have a 50% multiplier on overdose chance. Smokeleaf and Alcohol resistant metabolism cost reduced from {{--|2}} to {{--|1}}.
** '''<Drug> addict-immune''' genes renamed to [[#Alcohol impervious|<Drug> impervious]]. Addiction-immune genes for psychite, wake-up and go juice grants immunity to overdoses from the drug. Addiction-immune genes for alcohol, smokeleaf and psychite provides a 100% reduction in tolerance buildup. Smokeleaf and Alcohol impervious metabolism cost reduced from {{--|5}} to {{--|3}}.
**[[#Smokeleaf dependency|Smokeleaf]] and [[#Alcohol dependency|Alcohol dependency]] metabolism gain reduced from {{+|4}} to {{+|3}}.
** Fix: Remove reference to damage over time in acid spray ability description. {{Hover title|Spray a sticky acid substance from glands in the neck up through the mouth and all over the target area. The acid will stick to targets and burn them over time.|''[...] stick to targets and burn them over time.''}} to {{Hover title|Spray a sticky acid substance from glands in the neck up through the mouth and all over the target area. The acid will stick to targets and burn them.|''[...] stick to targets and burn them.''}}
** [[#Furskin|Furskin]] and [[#Beardless|beardless]] genes are now mutually exclusive.
** Buffed [[#Furry tail|furry tail]] minimum comfy temperature offset from {{Good|{{temperature|-5||delta}}}} to {{Good|{{temperature|-10||delta}}}}.
** When a [[#Deathless|deathless]] pawn takes damage that would have been lethal and falls into a deathrest coma instead, as an additional consequence they lose 3-6% of XP in a random skill. This should make non-death less trivial for these characters and preserve the sense of risk and danger. We’ll tuned this ongoing as needed.
** Fix: Bloodfeed can be used on pawns in mental states.
* [[Version/1.4.3557|1.4.3557]] - [[#Slow study|Slow study]] gene applies a {{Bad|x50%}} factor to [[Global Learning Factor]] instead of a {{--|50%}} offset.
* [[Version/1.4.3563|1.4.3563]] - Fix: Pawns with "dead calm" gene can get into fights over botched conversion attempts. Fix: Genes that remove all passions don't save previous values, causing passions to reset on removal. Fix: Pawns being carried by other pawns strains psychic bond.
* [[Version/1.4.3580|1.4.3580]] - Fix: Furskin_Average3 head uses the wrong graphic. Fix: Tattoos render below heavy brow. Fix: Furskin gene hair/fur color not staying when implanted with a skin color xenogene. Fix: Exception trying to visit sick pawn with neversleep gene.
* [[Version/1.4.3613|1.4.3613]] - Fix: Reimplant ability not working with custom xenotypes.
* [[Version/1.4.3641|1.4.3641]] - Fix: Inactive sterile gene affects fertility.
* [[Version/1.4.3682|1.4.3682]] - [[Arrest]]ing dead calm pawns now never fails, to prevent them going berserk.
* [[Version/1.5.4062|1.5.4062]] -
** Made psychic bond distance thought more permissive. As long as both pawns are on the same map and not suspended (cryptosleep casket) they get the positive thought.
** Remove reference to damage over time in acid spray gene description. ("...it will stick to enemies and burn them over time." to "...it will stick to enemies and burn them.")
** Added more acid filth texture options for acid spray so it never looks tiled.
** Attached helpful text to mouse when selected pawn is aiming animal warcall ability.
** Updated fire spew LOS highlighting.
** Updated psychic bonding hediff tooltip to factor in pawns contained in buildings.
** Clarify that pawns with no xenogenes cannot implant their xenogerm into another person. Show correct warning message on attempt.
** Fix: Pawns with genetic drug needs aren't getting mothballed. Can improve performance in late-game saves.
** Fix: Chemical genes affect tolerance buildup and addiction chance of all chemicals, not just the specified one.
** Fix: On colonist selection, wasters and hussars are currently generating without their drug dependencies.
** Fix: Small increments of pawn speed differences are lost due to integer calculations. Very quick and quick genes were effectively the same on an otherwise unmodified pawn.
** Fix: Drug dependency endogenes aren't properly being overridden by other drug-related xenogenes of the same chemical.
** Fix: Psychic bonds can form between two pawns that have the psychic bonding genes even if they are bonded to other people.
** Fix: Pawns still carry a weapon after getting incapable of violence gene.
** Fix: Pawns incapable of violence still can use combat gene abilities
** Fix: Fire spew can shoot through walls.
** Fix: Fire spew ability not leaning like other ranged attacks.
** Fix: Fire spew ability can't target walls.
** Fix: Perfect immunity doesn't block gut worms or muscle parasites.
* [[Version/1.6.4518|1.6.4518]] - Added 2 new genes: [[#Indoor dweller|Indoor dweller]] and [[#Webbed phalanges|webbed phalanges]]. The former is added to dirtmoles, resulting in complexity increasing from 9 -> 10, Net metabolism decreasing from +1 -> 0, hunger rate increasing from 90% -> 100%.
* [[Version/1.6.4535|1.6.4535]] - Made the [[breathless]] gene suppress the normal [[vacuum resistant]] gene, removing its metabolic impact.
* [[Version/1.6.4566|1.6.4566]] - Rebalanced the starjack xenotype, added the [[Low gravity adapted]] gene. Removed [[Awful plants]], replaced [[Poor melee]] with [[Awful melee]] and replaced [[Cold tolerant]] with [[Cold super-tolerant]]. Net metabolism decreasing from +1 -> 0, hunger rate increasing from 90% -> 100%. [[Breathless]] and [[Vacuum resistant]] now grants [[Minimum Comfortable Temperature]]: {{---|{{temperature|5||delta}}}}

'''Megaspiders''' are giant, bio-engineered, subterranean invertebrates and the largest and most dangerous of the three [[insectoid]] types.

== Acquisition ==
{{PAGENAME}}s can be found underground in [[World generation#Caves|caves]] and [[infestation]]s or inside [[ancient shrine]]s. They can be tamed by a [[Work #Handle|handler]].

== Summary ==
They are hostile towards any nearby [[colonists]], have plated armor that makes them quite resistant to ranged attack, and can do lethal amounts of damage in close combat. Like all insects, megaspiders only begin spawning in events where colonists come into contact with their underground habitat: In [[World generation#Caves|caves]], when opening an [[ancient danger]], during an [[Events#Infestation|infestation]], or by [[Deep drill|deep drilling]].

{{Insectoid Summary}}

== Analysis ==
=== Combat ===
Megaspiders are slightly slower than [[spelopede]]s and [[megascarab]]s. A common feature of any insectoid swarm is for these smaller, less dangerous creatures to glove the megaspiders' approach, absorbing the fire of your colonists and bogging them down until the big hitters are in range. Fully fit humans can outrun even megascarabs, so the strongest tactic is to hit and run, continually falling back in front of the swarm. If they've infested your base, open your doors and try to lead them out into the open.

[[Melee block]] tactics are very effective, but otherwise you should avoid melee combat. Megaspiders are sturdy and can do a lot of damage very quickly. Do not underestimate how many bullets they take to go down.

=== Taming ===
Wild megaspiders always generate hostile, making them difficult to tame as they will try to attack the animal handler. However, animal interactions during the process will interrupt any attacks. It may be ideal to equip your handler with armor, or to select a handler with a high [[melee]] skill for a higher [[melee dodge chance]] to reduce the risk of harm, though this is not strictly necessary.

Alternatively, a doctor has a small chance to [[bond]] when tending to a wild megaspider, instantly taming them.

As tamed pets, megaspiders offer few advantages over [[bear]]s, [[cougar]]s/[[panther]]s, or [[elephant]]s. Although the latter are all easier to tame, Megaspiders can be tamed en-masse depending on how many were downed during an infestation, require less training because of their lower wildness, and produce less filth than comparable animals.

Colonists who go near a hostile megaspider will flee from it by default, so you may need to adjust your handler's [[hostility response]] setting, or manually order your handler to interact with it.

== Training ==
{{TrainingTable}}

{{OdysseyIcon}} In addition, a {{PAGENAME}} can be trained to perform 'Attack Target': “Command the animal to attack a specific target that its master can see.” (Prerequisite needed: Attack)

'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}
== Event List <span class="mw-EventList_toggle" style="font-size:small; display:inline-block; float:right;"> </span> ==
For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

=== World events ===
:{{For|a guide to survive these events|World Quests Guide}}
This is a list of all events that can happen while on the overworld. Some events require a quest to trigger. Sub events are not quest events on their own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

|}

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

File:Raid relationship daughters of a .png|'''Raided by (relationship) mom!'''
File:Drop pods raid.png|'''Drop pod sappers'''
File:Sappers.png|'''Sappers'''
</gallery>

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.
<gallery widths="250px" heights="250px" class="left" mode="nolines">
File:Poison ship.png|'''Defoliator ship'''
File:Psychic ship.png|'''Psychic ship'''
</gallery>

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.
<div class="mw-customtoggle-XWeather" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide Extreme Weather Events}}</div>

<div id="mw-customcollapsible-XWeather" class="mw-collapsible">

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
{{Clear}}

==== Herd migration: (Animal) ====
[[File:Thrumbo herd migration.png|300px|right]]

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days. Below 800 raid points, a Psychic Drone is always Low level. Above 2000 Raid Points, a Psychic Drone is High level. Between 800 and 2000 Psychic drones are Medium level.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

}}
|}
Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

== World incidents ==
:{{For|a guide to survive these events|World Quests Guide}}
These are events related to/only triggered on the overworld.

<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible">

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
{{Clear}}

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
{{Clear}}

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

MortalSmurph: /* Drought */

{{Odyssey}}
{{Main|Events}}
The [[Odyssey]]{{OdysseyIcon}} DLC introduced new incidents specific to biomes or map features.

== Misc Odyssey ==
===Seasonal flooding ===
Rainfall upriver is causing the river to swell. The flooding will subside after several days.

Approximately 12 cells of land along rivers can become Shallow Flood Water. Any non-tree plants and flooring in those cells are destroyed. Fences, Barricades, Sandbags, Walls, Natural Stone walls, Graves, and similar can block the rising flood waters.

Seasonal Flooding must occur on river maps, with a temperature of at least -7 C, and in Spring or Permanent Summer. Water can rise for up to 4 days.

Seasonal Flooding recedes after another 4 to 6 days, or if temperatures drop below -7 C. When the flood recedes, the terrain returns to its original type.

Seasonal Flooding may only occur once every 40 days.

=== Gill rot ===

Fish populations are slowly declining due to a parasitic fungus known as gill rot. The fungus is harmless to people.

During Gill Rot, 15% of maximum Fish Population per body of water is lost per day. Gill Rot lasts 3 to 6 days. Gill Rot can only occur after day 45 and can only occur every 45 days. Gill Rot must occur on a map with Fish.

=== Orbital debris ===

A cloud of orbital debris is hurtling towards your position and will impact within seconds. Get your colonists under a roof.

Orbital Debris can only occur in Space. After a short delay, 12 to 16 pieces of debris will impact into non-roofed cells and damage any pawns nearby. The impact will leave a crater.

== Lava field==
=== Volcanic ash ===

Ash from a nearby volcanic eruption is filling the sky. The sun is blocked and the acrid air burns the lungs. The cloud will last several days.

Volcanic Ash completely blocks out the sun, causes a -3 thought Volcanic Ash and -10% breathing to anyone not under a roof.

Volcanic Ash can only occur after day 15 and once every 30 days.

=== Volcanic debris ===

A nearby volcanic eruption is showering the region with molten lava!

8 to 12 pieces of Volcanic Debris land in cells without a roof. A small pool of temporary shallow lava is created. Pawns can walk through this shallow lava. After a few days, the shallow lava turns into removable Cooled Lava. When the cooled lava is removed using the remove flooring command, the terrain returns to original type.

Volcanic Debris can only occur after day 15 and once every 30 days.

=== Lava Emergence ===
Lava is emerging from cracks in the ground! It'll continue to pool until it creates a small lake. It will then take several days to cool, after which it can be removed.

The lava will make temporary shallow lava that pawns can walk through. After a few days, the shallow lava turns into removable Cooled Lava. When the cooled lava is removed using the remove flooring command, the terrain returns to original type.

The lava emergence can flow over any pathable terrain and over chunks or items on the ground. The lava cannot flow through walls, doors, fences, barricades, graves, columns and other objects.

The shallow lava can light adjacent flammable objects on fire.

=== Lava Flow ===
Lava has begun to pour into the region, flooding the low-lying volcanic rock. Keep your colonists out of harm's way!

Lava will emerge from the edge of the map and will flow only over Volcanic Rock and Cooled Rock terrain. The Lava Flow will create Shallow lava that is pathable and leave behind Cooled Rock terrain after a few days. The lava cannot flow through walls, doors, fences, barricades, graves, columns and other objects.

The shallow lava can light adjacent flammable objects on fire.

Lava Flow can only happen once every 12 days.

==Glowforest==
===Bioluminescent spores===
Some variety of fungus is blossoming and releasing bioluminescent spores! The spores are strangely beautiful and pose no danger.

All Colonists, even blind colonists, on the Glowforest map with spores gain a +4 Biolumenentic Spores thought.

Biolumenescent Spores can only occur again after 15 days. The spores last between 8 and 18 hours.

===Boomshroom Sprout===
A cluster of explosive boomshrooms has sprouted nearby! These mushrooms only grow in darkness. Once they mature, they can be harvested for chemfuel. Be careful - mature boomshrooms explode if damaged.

==Grasslands==
===Drought===
Due to a recent lack of rain, a drought has begun. Outdoor plants will grow significantly slower.

During a drought rain, rainy thunderstorm and similar weather events are disabled. Crops grow at 30% of their growth speed.

Droughts last 6 to 10 days. Before a Drought appears, a "Drought (Initial)" event had already occurred unannounced.

===Drought (Initial)===
The hidden prequel event to a Drought. During Drought (Initial) no rain can occur. The rain that can be caused by large fires is also prevented. Drought (Initial) lasts 4 days and always leads to the standard Drought event.

Drought (Initial) can only fire again after 40 days.

{{Stub|reason= Missing new Odyssey terrain and weather mechanics}}
{{TOCright}}

The map '''environment''' are all aspects of the map that often can not be directly influenced by the player, such as terrain, weather conditions and lighting.

== Beauty ==
{{Main|Beauty}}
Terrain, flooring, objects, and plants attribute to a tile's beauty, which in turn can affect a colonist's mood.
The contents of a tile have a cumulative effect on its beauty; i.e. a granite chunk (beauty of -10) on a carpeted floor (beauty of +2) gives the tile a net beauty of -8.
Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside.

== Space ==
Environment space (as opposed to the [[Space|Need for Space]]) is the count of how much space there is to freely move around in a room. This is all the floor tiles that are either empty or have objects that can be passed through at full speed, such as chairs, building materials, and the various "spots". All objects that either slow down or prevent movement through are not counted towards Environment Space. The "Space" number shown in the Environment display is this count x 1.4. This number is a measure of the entire room, and does not change depending on where a pawn is standing.

== Flora ==
{{Main|Plants}}
Certain plants and trees have beauty, and may also provide [[cover]] to colonists.

== Light ==
{{Stub|section=1|reason=1) Relationship between light % and plant growth speed e.g. Tinctoria grows so slow in normal soil under torch light that it rots before it grows enough to harvest 2) Effects of [[Dark vision]] and [[Ideoligion#Lighting|Lighting:Darkness preferred]] on mentioned stat and mood penalties}}
{{For|the furniture item|standing lamp}}

Light can be generated artificially or naturally. Artificial light is produced by appliances in a limited range. Natural light is generated throughout the map on unroofed tiles. Roofed tiles will be dark unless lit artificially.

Occasionally an [[Events#Eclipse|eclipse]] befalls the planet. Natural daytime light is no longer generated until it ends.

Light's importance lies in the following effects:
* Plant growth - Most plants have light requirements to grow.
:* 0% only: {{DLC Icons|Nutrifungus}}
:* 0%+: {{#Ask: [[Min Grow Light::0]] [[Name::!Nutrifungus]]| format = template | template = DLC Icons | link = none | sort = From DLC, Name | sep = , }}
:* 30%+: {{#Ask: [[Min Grow Light::0.3]]| format = template | template = DLC Icons | link = none | sort = From DLC, Name | sep = , }}
:* 50%+: ''All other plants''
* Power - Solar generators only produce power when naturally lit.
* Colonists want 30% light or better. This affects:
:* Colonists' mood - Colonists in sustained darkness will have the [[Thoughts list#In darkness|'In darkness']] thought. Sleeping colonists will not have this thought. Therefore, lighting is not needed in areas only used for sleeping.
:* Colonists' movement speed - Colonists in darkness will have a reduced [[move speed]], scaling to 80% at a light level of 0%. Due to this, combat at night or under unlit roofed areas can lead to a disadvantage against non-human opponents, such as insects, manhunter animals, or mechanoids. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.
:* Colonists' global work speed - Similarly to their movement speed, colonists will have a work speed penalty when working in darkness, scaling to 80% at a light level of 0%. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.
* [[Surgery success chance factor]] is optimized at 50% light or better.

There are three light levels: ''Dark'' (0-29%), ''Lit'' (30-89%), and ''Brightly lit'' (90-100%). Each tile on the map has one of these light levels. The light level of a tile is listed in the tile's information area located above the Architect menu (when the menu is minimized). The light level is immediately followed by the brightness given in a percentage (%).

{| class="wikitable" style = "text-align:center; border-width=10;" width="260"
| colspan = 4 | '''Light levels according to Light (%)'''
|-
| style = "text-align:left;" | Light (%)

Based on a specific colour.
It pleases [[ideoligion]]s with the [[Ideoligion#Lighting|Lighting: Darklights Preferred]] precept, giving those with the precept a {{Thought| desc=This dim light is perfect. I feel focused and energized.| label=darklight| value=+4| stack=1}},

* [[Darktorch]]
* [[Fungus darktorch]]
* [[Standing lamp]] (configured correctly)
* [[Darklight brazier]]{{RoyaltyIcon}}

=== Artificial light sources ===
Light in roofed areas is provided by the following appliances:

<div><li style="display: inline-table;">
{| {{STDT| sortable c_11 text-center}}
! Name !! <abbr title="The furthest away a tile can be before it falls below 30% light">Light Radius</abbr>
|-
{{#ask: [[Light Radius::+]]
| format = template
| template = Ask Table Formatter
| ?Light Radius
| sort = From DLC, Name
| link = none
}}
|}
</li><div>

=== Daylight timing and latitude ===
Daylight, or natural light, is the light generated on unroofed tiles throughout the map. The timing and strength of daylight is affected by latitude, time of year, and time of day, due to the planet's apparent axial tilt.

This effect is more pronounced at extreme northern and southern latitudes, which can result in light levels not reaching 0% at night or 100% at daytime.

Near the central latitude, light level change throughout the day as follows:
{| class = "wikitable" width="180"
! Start time
! Light level
|- style="background-color:#FFFFF0"
| 4h || Lit
|- style="background-color:#FFFFD8"
| 7h || Brightly lit
|- style="background-color:#FFFFF0"
| 17h || Lit
|- style="background-color:#B8C0B8"

The calculation of sunlight is surprisingly involved. On a nutshell: the formula obtains the angle between the vectors Latitude and Sun Position, subtracts an angle θ from it (determined by Latitude), obtains the cosine of the difference, and divides this number by 0.7. Finally, this result is capped between 0 (no light) and 100% (full light).

If you only care about the final formula, go to "Final formula" below. Otherwise, carry on.

The amount of sunlight a given cell receives depends on its Latitude, Day of the year, and Hour of the day. The simplified steps to reach the final value are:

:1. Obtain the factor "u" for the given latitude
::{| class="wikitable"
|-
! Latitude !! Value of u
|-
| <= 70 || 0.2
|-
| [70, 75] || Latitude * 13/50-18
|-
| =>75|| 1.5
|}

:2. Obtain Sun Position Vector SP = <code>{SPx, SPy, SPz}</code>. Do note these formulas are not in degrees, but radians.
:* SPx = -cos(Hour * π / 12)
:* SPy = -cos(π * Day/30) * u
:* SPz = -sin(Hour * π / 12) [NOT ACTUALLY USED, BUT PART OF THE VECTOR]

:3. Calculate angle θ. Do note that the values of this table are in degrees. To convert to radians, multiply result by π / 180
::{| class="wikitable"
|-
! Latitud !! Value of θ
|-
| <= -60 || 19
|-
| [-60, 60] || 36 - abs(x) * 17/60 
|-
| [60, 70] || 19
|-
| [70, 75] || 299 - 4x
|-
| >75 || -1
|}

:4. Calculate the angle (Δ) between the vector Latitude (L) y SP.
:* Δ = arc cos [ ( cos(Latitude) * SPx + sen(Latitude) * SPy ) / <span style="white-space: nowrap">√<span style="text-decoration:overline;"> 1 + SPy<sup>2</sup> </span></span> ] 

:5. '''Sunlight''' = cos(Δ - θ)/0.7; Capped between 0 and 1 (100%).

Do note that the creation of the vector Latitude : <code>{cos(''latitude''), sin(''latitude''), 0}</code> was omitted for simplicity.

Interestingly, while some effects are applied differently above latitude <code>70</code> (70° N), these do not seem to apply below <code>-70</code> (70° S). This has some odd effects on extreme Latitudes, such as the south pole having neither full darkness nor full light.

Getting useful data from this formula is inconvenient. You can use [https://docs.google.com/spreadsheets/d/1dI8CoR9OMk679Gyvr8lXrKUNtfNdCQPp/edit?usp=sharing&ouid=114344865191558455918&rtpof=true&sd=true this google doc] to get a better idea of how many hours of daylight a given tile (based on Latitude) will have through the year.




== Openness ==
{{stub|section=1|reason=Large enough enclosed spaces seem to blur these boundaries}}
Openness refers to the often critical aspect of structures being open to the outside. It affects many things such as temperature, item deterioration, light, exposure to weather, and certain events.

Every tile on the map falls into one of three categories:
* Outdoors - not enclosed by any structure, even if there is a roof.
* Indoors - completely enclosed structure, completely roofed.
* Unroofed - completely enclosed structure, but with one or more unroofed tiles.

Sufficiently large unroofed rooms, approximately 300 tiles, are considered outdoors.{{Check Tag|Detail Needed}}

== Temperature ==
{{Main|Temperature}}
Environmental temperature is affected outdoors mainly by the map's biome and by the current season. Temperature affects a plant's ability to grow. Temperature affects a human's comfort, and health in extreme temperatures.

== Terrain ==
Terrain consists of the map's walking surface, terrain features, and mountain areas. Terrain affects things including walking speed, where plants can grow, and may prohibit construction.

'''Natural surface terrain''' includes soil, rich soil, marshy soil, marsh, mud, sand, lichen-covered dirt, gravel, rough stone (granite, marble, etc.), rough-hewn stone, shallow water, and deep water.

'''Terrain features''' include steam geysers and mountains. The steam from a geyser produces heat and an enclosed area around it will heat up unless unroofed. A mountain cannot be destroyed, even if all of its stone and ore has been mined out. What remains are terrain tiles listed as 'overhead mountain'.

=== Naturally generated surfaces ===
{{stub|section=1|reason=Anomaly terrains - Flesh and Gray surface, odyssey terrains}}
{{Split|section=1|reason=Individual pages for each terrain. Then make and distribute nav template}}
{{Recode|section=1|reason=Automate table once all pages created}}
{{For|the artificial flooring|Floors#Comparison table{{!}}Floors}}
While most terrain properties are self-explanatory, some require special attention.
* '''Path cost''' determines how difficult is to travers a given terrain.
* '''Move Speed Modifier''' is the net effect of said cost, and is obtained with the formula <code>13/(13 + Path cost)</code> rounded.
* '''Terrain Support''' determines what kind of structures can be build on a given terrain. If a given structure has a '''Terrain Affordance''' not listed for a given terrain, then said terrain is not a valid construction site. The types used are:
**'''Light''': Supports light structure.<br/>
**'''Medium''': Supports medium structures.<br/>
**'''Heavy''': Supports heavy structures.<br/>
**'''ShallowWater''': Can be built on with things that are waterproof.<br/>
**'''MovingFluid''' (moving water): Contains power usable for hydroelectrics.<br/>
**'''Bridgeable''': [[Bridge]] can be built over this terrain.<br/>
**'''GrowSoil''' (growable): Things can grow here. Unsure if is does anything or if merely indicative.<br/>
**'''Diggable''': Able to build [[grave]]s.<br/>
**'''SmoothableStone''' (smoothable): Can be ground and smoothed into smooth stone.<br/>
*'''Filth Mask''' determines what kind of [[filth]] can be applied on this terrain. Most natural floors only accept '''Unnatural''' filth, if any at all, but there are exceptions.
*'''Tag''' use is unclear. It may be used on map generation.

As of [[Version/1.5.4104]], all terrains with Heavy '''Terrain Support''' also support both Medium and Light. To help the readability of this table, only the '''Heavy''' tag will be used in those cases.

=== Steam geyser ===
{{stub|section=1|reason=Specific numbers on heat needed}}
[[File:Steam geyser.png|frameless|64px]] Steam geysers are terrain features that allow the placement of a [[geothermal generator]] on them and also output a significant amount of [[temperature|heat]] when sealed in a roofed room.

The steam geyser sprays after a random delay between {{Ticks|500}} and {{Ticks|2000}}. It will then spray for between {{Ticks|200}} and {{Ticks|500}}. While spraying, it will output 40 heat every {{ticks|20}}. Thus, it averages {{#expr: (60*40*((500+200)/2)/20)/((2000+500/2) + (200+500)/2) round 2}} heat per second, with no maximum temperature.

Besides their use in power generation, they can also be used to heat bases and greenhouses without the need for electricity or fuel by sealing them in. Like any means of [[temperature]] regulation, geysers require an enclosed and [[roof|roofed]] [[room]] to actually cause a change in heat. If you don't want heat, keep the geothermal room without a roof.

== Weather ==
{{stub|section=1|reason=Exact details of how large fires on the map cause rain needed. Rain details should be split from the rain weather type (because its not the only weather type that includes raining) and details discussed including short circuiting, increasing fuel consumption of torch, campfire and brazier variants, which weather types include rain, whether snow counts as rain for all mechanics etc, similarly Snow and its unique effects including [[Snow]] being merged into here. [[Odyssey DLC]] weathers need notes as they have additioonal effects, e.g. torrential rain causing flooding.}}

Weather events occur from time to time depending on the biome and time of year, with the current weather listed at the right edge of the screen. When a weather event ends the weather returns to Clear. Each weather event has a general effect on wind speed.

Wind speed continually varies between 0% to 150% but it is not displayed onscreen. Wind speed is a direct multiplier of a [[wind turbine]]'s nominal power output of {{Q|Wind turbine|Power Consumption #}}W. At 50% wind speed a wind turbine produces {{#expr:0.5*{{Q|Wind turbine|Power Consumption #}}}}W up to a maximum of {{#expr:1.5*{{Q|Wind turbine|Power Consumption #}}}}W at 150%. Note that the "max power output" listed in the infobox claims that {{Q|Wind turbine|Power Consumption #}}W is the maximum under "ideal conditions" - this is incorrect.

The [[Weather controller]]s {{RoyaltyIcon}} can force a single type of weather to constantly appear, and will only allow natural changes in weather once it is destroyed.

== Lightning ==
[[File:Dry Thunderstorm.png|400px|thumb|right|Lightning in a [[Environment#Weather|Dry thunderstorm]] ]]
'''Lightning''' is created either naturally through thunder and flashstorms, or artificially with the [[Flashstorm (psycast)|flashstorm]] psycast{{RoyaltyIcon}}. These do 10 [[Damage types#Flame|Flame]] damage in a 3x3 area (1.9 block radius) and start [[fire]]s to objects in the area of effect that are not under a roof. Dry thunderstorms can be especially dangerous, starting fires around the map without rain to put them out. The flashstorm psycast should be used with caution, preferably in areas without vegetation or during rain. Lightning can also be spawned in with a debug command in [[development mode]].

Lightning is bright enough to momentarily power [[solar generator]]s and grow [[plants]].

== Version history ==
* [[Version/0.0.245|0.0.245]] - Weather (rain/fog) now affects chances of hitting a target
* [[Version/0.3.410|0.3.410]] - Rain now slowly washes away [[Filth|blood]]. Added rich dirt patches.
* Beta 19/ 1.0 - Changed deep moving water to chest-deep moving water: walkable but slower than shallow water. Shallow water movement cost 12 -> 22. Sand fertility 6% -> 10%.
* [[Version/1.1.0|1.1.0]] - Fix: Wind turbines register no wind during windy storm.
* [[Version/1.4.3523|1.4.3523]] - Fix: Geysers have a deconstruct gizmo in god mode which causes and error when clicked.

{{Stub|reason= Missing new Odyssey terrain and weather mechanics}}
{{TOCright}}

The map '''environment''' are all aspects of the map that often can not be directly influenced by the player, such as terrain, weather conditions and lighting.

== Beauty ==
{{Main|Beauty}}
Terrain, flooring, objects, and plants attribute to a tile's beauty, which in turn can affect a colonist's mood.
The contents of a tile have a cumulative effect on its beauty; i.e. a granite chunk (beauty of -10) on a carpeted floor (beauty of +2) gives the tile a net beauty of -8.
Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside.

== Space ==
Environment space (as opposed to the [[Space|Need for Space]]) is the count of how much space there is to freely move around in a room. This is all the floor tiles that are either empty or have objects that can be passed through at full speed, such as chairs, building materials, and the various "spots". All objects that either slow down or prevent movement through are not counted towards Environment Space. The "Space" number shown in the Environment display is this count x 1.4. This number is a measure of the entire room, and does not change depending on where a pawn is standing.

== Flora ==
{{Main|Plants}}
Certain plants and trees have beauty, and may also provide [[cover]] to colonists.

== Light ==
{{Stub|section=1|reason=1) Relationship between light % and plant growth speed e.g. Tinctoria grows so slow in normal soil under torch light that it rots before it grows enough to harvest 2) Effects of [[Dark vision]] and [[Ideoligion#Lighting|Lighting:Darkness preferred]] on mentioned stat and mood penalties}}
{{For|the furniture item|standing lamp}}

Light can be generated artificially or naturally. Artificial light is produced by appliances in a limited range. Natural light is generated throughout the map on unroofed tiles. Roofed tiles will be dark unless lit artificially.

Occasionally an [[Events#Eclipse|eclipse]] befalls the planet. Natural daytime light is no longer generated until it ends.

Light's importance lies in the following effects:
* Plant growth - Most plants have light requirements to grow.
:* 0% only: {{DLC Icons|Nutrifungus}}
:* 0%+: {{#Ask: [[Min Grow Light::0]] [[Name::!Nutrifungus]]| format = template | template = DLC Icons | link = none | sort = From DLC, Name | sep = , }}
:* 30%+: {{#Ask: [[Min Grow Light::0.3]]| format = template | template = DLC Icons | link = none | sort = From DLC, Name | sep = , }}
:* 50%+: ''All other plants''
* Power - Solar generators only produce power when naturally lit.
* Colonists want 30% light or better. This affects:
:* Colonists' mood - Colonists in sustained darkness will have the [[Thoughts list#In darkness|'In darkness']] thought. Sleeping colonists will not have this thought. Therefore, lighting is not needed in areas only used for sleeping.
:* Colonists' movement speed - Colonists in darkness will have a reduced [[move speed]], scaling to 80% at a light level of 0%. Due to this, combat at night or under unlit roofed areas can lead to a disadvantage against non-human opponents, such as insects, manhunter animals, or mechanoids. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.
:* Colonists' global work speed - Similarly to their movement speed, colonists will have a work speed penalty when working in darkness, scaling to 80% at a light level of 0%. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.
* [[Surgery success chance factor]] is optimized at 50% light or better.

There are three light levels: ''Dark'' (0-29%), ''Lit'' (30-89%), and ''Brightly lit'' (90-100%). Each tile on the map has one of these light levels. The light level of a tile is listed in the tile's information area located above the Architect menu (when the menu is minimized). The light level is immediately followed by the brightness given in a percentage (%).

{| class="wikitable" style = "text-align:center; border-width=10;" width="260"

* [[Darktorch]]
* [[Fungus darktorch]]
* [[Standing lamp]] (configured correctly)
* [[Darklight brazier]]{{RoyaltyIcon}}

=== Artificial light sources ===
Light in roofed areas is provided by the following appliances:

<div><li style="display: inline-table;">
{| {{STDT| sortable c_11 text-center}}
! Name !! <abbr title="The furthest away a tile can be before it falls below 30% light">Light Radius</abbr>
|-
{{#ask: [[Light Radius::+]]
| format = template
| template = Ask Table Formatter
| ?Light Radius
| sort = From DLC, Name
| link = none
}}
|}
</li><div>

=== Daylight timing and latitude ===
Daylight, or natural light, is the light generated on unroofed tiles throughout the map. The timing and strength of daylight is affected by latitude, time of year, and time of day, due to the planet's apparent axial tilt.

This effect is more pronounced at extreme northern and southern latitudes, which can result in light levels not reaching 0% at night or 100% at daytime.

Near the central latitude, light level change throughout the day as follows:
{| class = "wikitable" width="180"
! Start time
! Light level
|- style="background-color:#FFFFF0"
| 4h || Lit
|- style="background-color:#FFFFD8"
| 7h || Brightly lit
|- style="background-color:#FFFFF0"
| 17h || Lit
|- style="background-color:#B8C0B8"
| 20h || Dark
|}

==== Day Length Table ====
Note that the below values represent the number of hours that the light level is above 30%, meaning there is no guarantee that it will reach 100%.

The calculation of sunlight is surprisingly involved. On a nutshell: the formula obtains the angle between the vectors Latitude and Sun Position, subtracts an angle θ from it (determined by Latitude), obtains the cosine of the difference, and divides this number by 0.7. Finally, this result is capped between 0 (no light) and 100% (full light).

If you only care about the final formula, go to "Final formula" below. Otherwise, carry on.

The amount of sunlight a given cell receives depends on its Latitude, Day of the year, and Hour of the day. The simplified steps to reach the final value are:

:1. Obtain the factor "u" for the given latitude
::{| class="wikitable"
|-
! Latitude !! Value of u
|-
| <= 70 || 0.2
|-
| [70, 75] || Latitude * 13/50-18
|-
| =>75|| 1.5
|}

:2. Obtain Sun Position Vector SP = <code>{SPx, SPy, SPz}</code>. Do note these formulas are not in degrees, but radians.
:* SPx = -cos(Hour * π / 12)
:* SPy = -cos(π * Day/30) * u
:* SPz = -sin(Hour * π / 12) [NOT ACTUALLY USED, BUT PART OF THE VECTOR]

:3. Calculate angle θ. Do note that the values of this table are in degrees. To convert to radians, multiply result by π / 180
::{| class="wikitable"
|-
! Latitud !! Value of θ
|-
| <= -60 || 19
|-
| [-60, 60] || 36 - abs(x) * 17/60 
|-
| [60, 70] || 19
|-
| [70, 75] || 299 - 4x
|-
| >75 || -1
|}

:4. Calculate the angle (Δ) between the vector Latitude (L) y SP.
:* Δ = arc cos [ ( cos(Latitude) * SPx + sen(Latitude) * SPy ) / <span style="white-space: nowrap">√<span style="text-decoration:overline;"> 1 + SPy<sup>2</sup> </span></span> ] 

:5. '''Sunlight''' = cos(Δ - θ)/0.7; Capped between 0 and 1 (100%).

Do note that the creation of the vector Latitude : <code>{cos(''latitude''), sin(''latitude''), 0}</code> was omitted for simplicity.

Interestingly, while some effects are applied differently above latitude <code>70</code> (70° N), these do not seem to apply below <code>-70</code> (70° S). This has some odd effects on extreme Latitudes, such as the south pole having neither full darkness nor full light.

Getting useful data from this formula is inconvenient. You can use [https://docs.google.com/spreadsheets/d/1dI8CoR9OMk679Gyvr8lXrKUNtfNdCQPp/edit?usp=sharing&ouid=114344865191558455918&rtpof=true&sd=true this google doc] to get a better idea of how many hours of daylight a given tile (based on Latitude) will have through the year.




== Openness ==
{{stub|section=1|reason=Large enough enclosed spaces seem to blur these boundaries}}
Openness refers to the often critical aspect of structures being open to the outside. It affects many things such as temperature, item deterioration, light, exposure to weather, and certain events.

Every tile on the map falls into one of three categories:
* Outdoors - not enclosed by any structure, even if there is a roof.
* Indoors - completely enclosed structure, completely roofed.
* Unroofed - completely enclosed structure, but with one or more unroofed tiles.

Sufficiently large unroofed rooms, approximately 300 tiles, are considered outdoors.{{Check Tag|Detail Needed}}

== Temperature ==
{{Main|Temperature}}
Environmental temperature is affected outdoors mainly by the map's biome and by the current season. Temperature affects a plant's ability to grow. Temperature affects a human's comfort, and health in extreme temperatures.

== Terrain ==
Terrain consists of the map's walking surface, terrain features, and mountain areas. Terrain affects things including walking speed, where plants can grow, and may prohibit construction.

'''Natural surface terrain''' includes soil, rich soil, marshy soil, marsh, mud, sand, lichen-covered dirt, gravel, rough stone (granite, marble, etc.), rough-hewn stone, shallow water, and deep water.

'''Terrain features''' include steam geysers and mountains. The steam from a geyser produces heat and an enclosed area around it will heat up unless unroofed. A mountain cannot be destroyed, even if all of its stone and ore has been mined out. What remains are terrain tiles listed as 'overhead mountain'.

=== Naturally generated surfaces ===
{{stub|section=1|reason=Anomaly terrains - Flesh and Gray surface, odyssey terrains}}
{{Split|section=1|reason=Individual pages for each terrain. Then make and distribute nav template}}
{{Recode|section=1|reason=Automate table once all pages created}}
{{For|the artificial flooring|Floors#Comparison table{{!}}Floors}}
While most terrain properties are self-explanatory, some require special attention.
* '''Path cost''' determines how difficult is to travers a given terrain.
* '''Move Speed Modifier''' is the net effect of said cost, and is obtained with the formula <code>13/(13 + Path cost)</code> rounded.
* '''Terrain Support''' determines what kind of structures can be build on a given terrain. If a given structure has a '''Terrain Affordance''' not listed for a given terrain, then said terrain is not a valid construction site. The types used are:
**'''Light''': Supports light structure.<br/>
**'''Medium''': Supports medium structures.<br/>
**'''Heavy''': Supports heavy structures.<br/>
**'''ShallowWater''': Can be built on with things that are waterproof.<br/>
**'''MovingFluid''' (moving water): Contains power usable for hydroelectrics.<br/>
**'''Bridgeable''': [[Bridge]] can be built over this terrain.<br/>
**'''GrowSoil''' (growable): Things can grow here. Unsure if is does anything or if merely indicative.<br/>
**'''Diggable''': Able to build [[grave]]s.<br/>
**'''SmoothableStone''' (smoothable): Can be ground and smoothed into smooth stone.<br/>
*'''Filth Mask''' determines what kind of [[filth]] can be applied on this terrain. Most natural floors only accept '''Unnatural''' filth, if any at all, but there are exceptions.
*'''Tag''' use is unclear. It may be used on map generation.

As of [[Version/1.5.4104]], all terrains with Heavy '''Terrain Support''' also support both Medium and Light. To help the readability of this table, only the '''Heavy''' tag will be used in those cases.

=== Steam geyser ===
{{stub|section=1|reason=Specific numbers on heat needed}}
[[File:Steam geyser.png|frameless|64px]] Steam geysers are terrain features that allow the placement of a [[geothermal generator]] on them and also output a significant amount of [[temperature|heat]] when sealed in a roofed room.

The steam geyser sprays after a random delay between {{Ticks|500}} and {{Ticks|2000}}. It will then spray for between {{Ticks|200}} and {{Ticks|500}}. While spraying, it will output 40 heat every {{ticks|20}}. Thus, it averages {{#expr: (60*40*((500+200)/2)/20)/((2000+500/2) + (200+500)/2) round 2}} heat per second, with no maximum temperature.

Besides their use in power generation, they can also be used to heat bases and greenhouses without the need for electricity or fuel by sealing them in. Like any means of [[temperature]] regulation, geysers require an enclosed and [[roof|roofed]] [[room]] to actually cause a change in heat. If you don't want heat, keep the geothermal room without a roof.

== Weather ==
{{stub|section=1|reason=Exact details of how large fires on the map cause rain needed. Rain details should be split from the rain weather type (because its not the only weather type that includes raining) and details discussed including short circuiting, increasing fuel consumption of torch, campfire and brazier variants, which weather types include rain, whether snow counts as rain for all mechanics etc, similarly Snow and its unique effects including [[Snow]] being merged into here. [[Odyssey DLC]] weathers need notes as they have additioonal effects, e.g. torrential rain causing flooding.}}

Weather events occur from time to time depending on the biome and time of year, with the current weather listed at the right edge of the screen. When a weather event ends the weather returns to Clear. Each weather event has a general effect on wind speed.

Wind speed continually varies between 0% to 150% but it is not displayed onscreen. Wind speed is a direct multiplier of a [[wind turbine]]'s nominal power output of {{Q|Wind turbine|Power Consumption #}}W. At 50% wind speed a wind turbine produces {{#expr:0.5*{{Q|Wind turbine|Power Consumption #}}}}W up to a maximum of {{#expr:1.5*{{Q|Wind turbine|Power Consumption #}}}}W at 150%. Note that the "max power output" listed in the infobox claims that {{Q|Wind turbine|Power Consumption #}}W is the maximum under "ideal conditions" - this is incorrect.

The [[Weather controller]]s {{RoyaltyIcon}} can force a single type of weather to constantly appear, and will only allow natural changes in weather once it is destroyed.

== Lightning ==
[[File:Dry Thunderstorm.png|400px|thumb|right|Lightning in a [[Environment#Weather|Dry thunderstorm]] ]]
'''Lightning''' is created either naturally through thunder and flashstorms, or artificially with the [[Flashstorm (psycast)|flashstorm]] psycast{{RoyaltyIcon}}. These do 10 [[Damage types#Flame|Flame]] damage in a 3x3 area (1.9 block radius) and start [[fire]]s to objects in the area of effect that are not under a roof. Dry thunderstorms can be especially dangerous, starting fires around the map without rain to put them out. The flashstorm psycast should be used with caution, preferably in areas without vegetation or during rain. Lightning can also be spawned in with a debug command in [[development mode]].

Lightning is bright enough to momentarily power [[solar generator]]s and grow [[plants]].

== Version history ==
* [[Version/0.0.245|0.0.245]] - Weather (rain/fog) now affects chances of hitting a target
* [[Version/0.3.410|0.3.410]] - Rain now slowly washes away [[Filth|blood]]. Added rich dirt patches.
* Beta 19/ 1.0 - Changed deep moving water to chest-deep moving water: walkable but slower than shallow water. Shallow water movement cost 12 -> 22. Sand fertility 6% -> 10%.
* [[Version/1.1.0|1.1.0]] - Fix: Wind turbines register no wind during windy storm.
* [[Version/1.4.3523|1.4.3523]] - Fix: Geysers have a deconstruct gizmo in god mode which causes and error when clicked.

MortalSmurph: Orbital Debris

{{Odyssey}}
{{Main|Events}}
The [[Odyssey]]{{OdysseyIcon}} DLC introduced new incidents specific to biomes or map features.

== Seasonal Flooding ==
Rainfall upriver is causing the river to swell. The flooding will subside after several days.

Approximately 12 cells of land along rivers can become Shallow Flood Water. Any non-tree plants and flooring in those cells are destroyed. Fences, Barricades, Sandbags, Walls, Natural Stone walls, Graves, and similar can block the rising flood waters.

Seasonal Flooding must occur on river maps, with a temperature of at least -7 C, and in Spring or Permanent Summer. Water can rise for up to 4 days.

Seasonal Flooding recedes after another 4 to 6 days, or if temperatures drop below -7 C. Seasonal Flooding may only occur once every 40 days.

== Gill Rot ==

Fish populations are slowly declining due to a parasitic fungus known as gill rot. The fungus is harmless to people.

During Gill Rot, 15% of maximum Fish Population per body of water is lost per day. Gill Rot lasts 3 to 6 days. Gill Rot can only occur after day 45 and can only occur every 45 days. Gill Rot must occur on a map with Fish.

== Orbital Debris ==

A cloud of orbital debris is hurtling towards your position and will impact within seconds. Get your colonists under a roof.

Orbital Debris can only occur in Space. After a short delay, 12 to 16 pieces of debris will impact into non-roofed cells and damage any pawns nearby. The impact will leave a crater.

{{Stub|reason=Ideology events. Recover lost content from major rewrite OR revert to prior to rewrite}}
{{For|a guide to survive events|Events Guide}}
'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}
== Event List <span class="mw-EventList_toggle" style="font-size:small; display:inline-block; float:right;"> </span> ==
For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

This is a list of all events that can happen while on the overworld. Some events require a quest to trigger. Sub events are not quest events on their own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

|}

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

File:Sappers.png|'''Sappers'''
</gallery>

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.
<gallery widths="250px" heights="250px" class="left" mode="nolines">
File:Poison ship.png|'''Defoliator ship'''
File:Psychic ship.png|'''Psychic ship'''
</gallery>

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.

<div id="mw-customcollapsible-XWeather" class="mw-collapsible">

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

==== Wild (wo)man wanders in ====
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

</gallery>

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Birthday ====
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a [[heart attack]].
{{Clear}}

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Disease ====
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].

[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

}}
|}
Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible">

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

#* Success = 0.55 * ( 1 / 0.64) = 0.859375
#* Flounder = 0.2
#* Backfire = 0.1 * 0.64 = 0.064

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.
<span class="mw-Gameend_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Gameend_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
{{Clear}}

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.
</div>

== Legacy events ==
Events from previous versions of RimWorld, now removed.

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
{{Clear}}

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
</div>

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

{{For|a guide to survive events|Events Guide}}
'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}
== Event List <span class="mw-EventList_toggle" style="font-size:small; display:inline-block; float:right;"> </span> ==
For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

This is a list of all events that can happen while on the overworld. Some events require a quest to trigger. Sub events are not quest events on their own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

|}

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.

</gallery>

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.
<div class="mw-customtoggle-XWeather" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide Extreme Weather Events}}</div>

<div id="mw-customcollapsible-XWeather" class="mw-collapsible">

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
{{Clear}}

==== Herd migration: (Animal) ====
[[File:Thrumbo herd migration.png|300px|right]]

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

==== Wild (wo)man wanders in ====
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Birthday ====
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a [[heart attack]].
{{Clear}}

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Disease ====
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].

[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

}}
|}
Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.
</div>

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

== World incidents ==
:{{For|a guide to survive these events|World Quests Guide}}
These are events related to/only triggered on the overworld.
<div class="mw-customtoggle-WorldEvents" style="background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide World Events}}</div>

<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible">

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

</div>
{{clear}}

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.
<span class="mw-Gameend_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Gameend_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
{{Clear}}

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.
</div>

== Legacy events ==
Events from previous versions of RimWorld, now removed.
<span class="mw-Legacy_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Legacy_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
{{Clear}}

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
</div>

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

{{For|a guide to survive events|Events Guide}}
'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}
== Event List <span class="mw-EventList_toggle" style="font-size:small; display:inline-block; float:right;"> </span> ==
For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

=== World events ===
:{{For|a guide to survive these events|World Quests Guide}}
This is a list of all events that can happen while on the overworld. Some events require a quest to trigger. Sub events are not quest events on their own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

File:Raid relationship daughters of a .png|'''Raided by (relationship) mom!'''
File:Drop pods raid.png|'''Drop pod sappers'''
File:Sappers.png|'''Sappers'''
</gallery>

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.
<gallery widths="250px" heights="250px" class="left" mode="nolines">
File:Poison ship.png|'''Defoliator ship'''
File:Psychic ship.png|'''Psychic ship'''
</gallery>

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.
<div class="mw-customtoggle-XWeather" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide Extreme Weather Events}}</div>

<div id="mw-customcollapsible-XWeather" class="mw-collapsible">

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
{{Clear}}

==== Herd migration: (Animal) ====
[[File:Thrumbo herd migration.png|300px|right]]

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

==== Wild (wo)man wanders in ====
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Birthday ====
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a [[heart attack]].
{{Clear}}

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Disease ====
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].

[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

}}
|}
Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

== World incidents ==
:{{For|a guide to survive these events|World Quests Guide}}
These are events related to/only triggered on the overworld.

<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible">

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
</div>

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

{{For|a guide to survive events|Events Guide}}
'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}

For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

|}

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

</gallery>

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
{{Clear}}

==== Herd migration: (Animal) ====
[[File:Thrumbo herd migration.png|300px|right]]

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

==== Wild (wo)man wanders in ====
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Birthday ====
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a [[heart attack]].
{{Clear}}

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Disease ====
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].

[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.
</div>

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

== World incidents ==
:{{For|a guide to survive these events|World Quests Guide}}
These are events related to/only triggered on the overworld.

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

Take a level 12 Social negotiator as an example:

{{clear}}

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.
<span class="mw-Gameend_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Gameend_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
{{Clear}}

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.
</div>

== Legacy events ==
Events from previous versions of RimWorld, now removed.
<span class="mw-Legacy_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Legacy_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
{{Clear}}

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
</div>

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

{{For|a guide to survive events|Events Guide}}
'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].

Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called [[Quests]] which work under different rules.

{{TOCright}}
== Event List <span class="mw-EventList_toggle" style="font-size:small; display:inline-block; float:right;"> </span> ==
For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

<div id="mw-EventList_collapsible" class="mw-collapsible">

=== Storyteller events ===
These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

This is a list of all events that can happen while on the overworld. Some events require a quest to trigger. Sub events are not quest events on their own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

=== Anomaly events ===
{{Anomaly}}
:{{For|the complete list of events|Events/Anomaly}}

Events from the [[Anomaly]]{{AnomalyIcon}} DLC work different from normal events and are intrinsically related to the [[Monolith]] structure. Due to this, all Anomaly events will be listed on its own page.

== Major threats ==
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].

[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.

<div class="mw-customtoggle-Majorthreats" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">
{{Center|Show/Hide Major Threat Details}}</div>

<div class="mw-collapsible" id="mw-customcollapsible-Majorthreats">

=== Major threats generation===
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

|}

=== Raid Generation ===
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

=== Enemy attack ===
----
{{Main|Raids}}
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.

===== Arrival methods =====
Tribal-level factions can't use drop pods, so are limited to assaults.

* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.

===== Types =====
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
* '''Siege''': See below.

File:Sappers.png|'''Sappers'''
</gallery>

==== Siege ====
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.

=== Infestation ===
----
{{main|Infestation}}
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.

The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.

The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.

=== Manhunter pack ===
----
{{For|the mental state that makes these animals hostile|Manhunter}}
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]

=== Psychic wave ===
----
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.

=== Crashed ship part ===
----
{{For|the help guide|Defense structures#Crashed ships}}
{{For|information on the ship parts themselves|Crashed ship parts}}
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

==== Defoliator ship ====
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.

==== Psychic ship ====
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

====== Drone intensifies ======
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.
<gallery widths="250px" heights="250px" class="left" mode="nolines">
File:Poison ship.png|'''Defoliator ship'''
File:Psychic ship.png|'''Psychic ship'''
</gallery>

=== Mech cluster ===
----
{{Royalty|Section=1}}
{{main|Mech cluster}}
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.

=== Problem causer ===
----
{{Royalty|Section=1}}
{{main|Condition causer}}
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.

</div>

== Extreme weather ==
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.
<div class="mw-customtoggle-XWeather" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide Extreme Weather Events}}</div>

<div id="mw-customcollapsible-XWeather" class="mw-collapsible">

=== Flashstorm ===
----
[[File:FlashstormScreenshot.png|300px|thumb|left]]
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"

'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the [[Flashstorm (psycast)|Flashstorm]] psycast {{RoyaltyIcon}}, but will not show up as a notification.
{{clear}}

=== Toxic fallout ===
----
"''A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly sickened by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to nearly a quadrum.''"

'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a [[roof]]. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].

Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

=== Volcanic winter ===
----
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"

'''Volcanic winter''' lowers the [[temperature]] and natural [[light]],which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by {{Temperature|7||delta}} and the light by 30% over the course of {{Ticks/gametime|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.{{Check Tag|Mechanic detail|What does this mean mechanically?}}

Note that volcanic winters won't kill plants outright, but they still have the potential to kill plants should the temperature drop to a sufficiently cold point. Like cold snaps, building warmed and lit greenhouses can help with crop growth during volcanic winters.

</div>

== Random Events ==
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.

=== Quests ===
{{Main|Quests}}
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

=== Good ===
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>

<div id="mw-customcollapsible-RandomGood" class="mw-collapsible">

==== Ambrosia sprout ====
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

The ambrosia event must initially spawn in the growing season of the map tile.

It can only happen in the following [[biomes]]:
<div style="width:500px"><ul class="ul-column-width-150">
* [[Tropical rainforest]]
* [[Tropical swamp]]
* [[Temperate forest]]
* [[Temperate swamp]]
* [[Boreal forest]]
* [[Arid shrubland]]
</ul></div>

==== Animals join ====
Tamed [[dog]]s or [[farm animals]] from off-map join your colony.

==== Animal self-tamed ====
[[File:Thrumbo self-tamed.png|300px|right]]
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

==== Aurora ====
An aurora lights up the night sky, giving a {{Thought|desc=The view is amazing.|label=beautiful aurora|value=+14|stack=1}} boost to anyone who is not [[Sight|blind]] and is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the [[light]] level.

During an aurora a pawn looking for a recreation source is 8 times more likely to choose [[Recreation#Skygazing|skygazing]], and it restores 5 times more recreation.

==== Cargo pods ====
[[File:Cargo pods.png|300px|right]]
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
{{Clear}}

==== Herd migration: (Animal) ====
[[File:Thrumbo herd migration.png|300px|right]]

A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

The migrating animal will always be an animal that can spawn in the map's [[biome]] (or [[biomes]]{{OdysseyIcon}}).
* Coastal animals{{OdysseyIcon}} will only be selected if the map is a coastal map.
* If the map is [[polluted]]{{BiotechIcon}}, there's a chance that the game will select a animal that only spawns in polluted maps instead. The more polluted the map is, the higher the chance.

The number of animals spawned in will be one of these value, whichever is higher:
* A random number between 3 and 5
* 4 divided by the animal's [[body size]], rounded up.

This event only occurs in the following biomes:

<div style="column-count:3; width:350px;">
* [[Sea ice]]
* [[Ice sheet]]
* [[Tundra]]
* [[Desert]]
* [[Extreme desert]]

</div>

This event may also be triggered on any biomes with the [[draw animals]]{{AnomalyIcon}} psychic ritual.

==== Party ====
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.

==== Psychic soothe ====
[[File:Psychic soothe.png|300px|right]]

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
{{Clear}}

==== (Trader type) ====
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

==== (Trader type) from (Faction) ====
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.

==== Transport pod crash ====
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.

===== Paralytic abasia =====
{{Royalty|section=1}}
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

==== Wanderer joins ====
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

</gallery>

==== Wild (wo)man wanders in ====
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with [[Ideology]].

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

==== Traveler Visit ====
{{:Traveler}}

==== Visitor(s) ====
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

==== Royal Tribute Collector ====
{{Royalty|section=1}}
{{Main|Royal tribute collector}}
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].

==== Gauranlen pod sprout ====
{{Ideology|section=1}}
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}

A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

==== Polux tree sprout ====
{{Biotech|section=1}}
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

</div>

=== Bad ===
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
<div id="mw-customcollapsible-RandomBad" class="mw-collapsible">

==== Beavers! ====
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

==== Birthday ====
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a [[heart attack]].
{{Clear}}

==== Blight ====
{{main|Blight}}
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]

Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

==== Disease ====
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].

[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

==== Eclipse ====
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.

Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.

It will not reoccur for 15 days

==== Heat wave ====
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17||delta}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.

The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

==== Cold snap ====
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20||delta}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.

==== Mad animal ====
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.

==== Psychic drone ====
{{For|the moodlet|Mood#Exotic}}
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.

==== Solar flare ====
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.

* Colonies that rely on turrets for defense will become vulnerable to raids.
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}

Due to its length, most of the adverse effects are manageable.

==== Zzztt ====
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:
<div style="column-count:3; width:700px;">
* [[Sun lamp]]
* [[Tube television]]
* [[Flatscreen television]]
* [[Megascreen television]]
* [[Comms console]]
* [[Multi-analyzer]]
* [[Vitals monitor]]
* [[Battery]]
* [[Electric tailor bench]]
* [[Electric smithy]]
* [[Machining table]]
* [[Electric stove]]
* [[Electric smelter]]
* [[Biofuel refinery]]
* [[Fabrication bench]]
* [[Hi-tech research bench]]
* [[Electric crematorium]]
* [[Heater]]
* [[Lightball]]{{IdeologyIcon}}
* [[Loudspeaker]]{{IdeologyIcon}}
* [[Autobong]]{{IdeologyIcon}}
</div>

Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

{| class="wikitable"
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
|}

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

}}
|}
Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

==== Transport pod crash (Ghoul) ====
{{Anomaly|section=1}}
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

==== Gray pall ====
{{Anomaly|section=1}}
A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.
</div>

== Incidental Events ==
:{{For|a detailed list of these events|Events/Incidental}}
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

== World incidents ==
:{{For|a guide to survive these events|World Quests Guide}}
These are events related to/only triggered on the overworld.
<div class="mw-customtoggle-WorldEvents" style="background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide World Events}}</div>

<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible">

==== Attack begun ====
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.

==== Bandit camp opportunity ====
{{See also|Offense tactics}}

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

==== Caravan ambushed / (manhunters) ====
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

===== Caravan battle won =====
This event will tell you if your people won their fight, and can reform the caravan on the world map.

==== Caravan arrived at (Location) ====
This is a simple notification that your caravan has arrived at their destination.

==== Caravan lost ====
[[File:Caravan destroyed.png|thumb|right|400px]]
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
{{Clear}}

==== Caravan meeting by (Caravan ID) ====
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

==== Caravan ready ====
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

==== Demand ====
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

==== Peace talks ====
[[File:Peace talks.png|thumb|right|300px]]

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain 6000 XP to social skill.

{| class="wikitable"
|-
! Result !! Description !! Base Weight
|-
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from {{+|100}} to {{+|110}}. In addition, the faction will give a farewell gift worth between 500 and 1200 silver. || 0.1
|-
| '''Peace talk success''' || The talks were a success, and relations between the factions have warmed somewhat, from {{+|60}} to {{+|70}}. || 0.55
|-
| '''Peace talk flounder''' || The talks were neither successful nor a failure, and relations remain unchanged. || 0.2
|-
| '''Peace talk backfire''' || The peace talks backfired, and relations have gotten worse than they started, from {{--|10}} to {{--|20}} relations. || 0.1
|-
| '''Peace talk disaster''' || The peace talks have failed so miserably that the faction hates you a lot more now, dropping your relations by up to {{--|50}}, as well as turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party.<br>Do note that relations will not drop below {{--|75}}, so there's no penalty if relation are worse than that. || 0.05
|}

===== Outcome chances =====
The actual outcome chances are dependent on the negotiator's [[Negotiation Ability]] stat and, if the [[Ideology DLC]] is active, the presence/absence of your [[leader]]{{IdeologyIcon}}.
<div id="wrap" style="width:820px; margin:10;">
<div id="left_col" style="float:left; width:400px;">
First, the negotiator's [[Negotiation Ability]] stat goes through a simple curve to determine the '''bad outcome factor'''. In this formula, X is the decimal equivalent to the negotiation ability. As an example, a negotiation ability of 130% gives us an X value of 1.3.
{| class="wikitable"
|-
! Negotiation Ability !! Bad outcome factor !! Observations
|-
| '''0%''' || 4 || Not possible in practice.
|-
| '''0% - 100%''' || 4 - 3*X ||
|-
| '''100%''' || 1 || Equivalent to lvl 8 Social
|-
| '''100% - 150%''' || 1 - 1.2 * (X-1) ||
|-
| '''150%''' || 0.4 || Equivalent to lvl 15+ Social
|}
</div>
<div id="right_col" style="float:right; width:400px;">
If the [[Ideology DLC]] is active, the '''bad outcome factor''' is then multiplied by:
* {{Good|0.95}}, if the colony leader is present on this caravan.
* {{Bad|1.05}}, if he's not.

The new weight of each outcome is calculated afterwards.
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
* Success = 0.55 * ( 1 / Bad Outcome Factor)
* Flounder = 0.2
* Backfire = 0.1 * Bad Outcome Factor
* Disaster = 0.05 * Bad Outcome Factor
The sum total of the new weights is then calculated.

</div>
</div>
{{clear}}
Finally, the probability of each outcome is:

:{{Math|big=0|Probability of each outcome {{=}} New Weight ÷ Sum Total of Weights}}

<div class="mw-customtoggle-PeaceTalkEx" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Example</div>

{{clear}}

==== Rescuee joins ====
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

=== Sub-events ===
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

==== Ambush ====
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
{{Clear}}

==== Sleeping mechanoids ====
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
</div>

== Game endings ==
When these happen, they signify that your game has ended, one way or another.
<span class="mw-Gameend_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
<div id="mw-Gameend_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">

==== Game over ====
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
{{Clear}}

==== Planetkiller ====
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
{{Clear}}

==== Ending - The Archonexus Core ====
For specifics, see [[Endings#The_Archonexus]].

Once it happens, your colony is successfully noticed by an archotech. What happens next is left to speculation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.
</div>

== Legacy events ==
Events from previous versions of RimWorld, now removed.

=== Bonded animal's death ===
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
{{Clear}}

=== Bonded master's death ===
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

=== Breakdown: (Machine) ===
In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

=== Tornado ===
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
</div>

== Event data ==
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

The thinking mind of the mechanoid swarm. The cerebrex core commands mechanoids across the entire planet.

== Summary ==

== Analysis ==

Four Mechhive birthers are around the Cerebrex Core. Each birther regularly produces mechs that gather around the Cerebrex Core and eventually attack the player.

Mechs are produced every 6 to 14 hours. The higher the Raid Points, the faster the mechs are produced. Chart below. The first number is player raid points and the second is ticks between mechs spawning. So at 10,000 raid points, there are 15,000 ticks between mechs spawning which is 6 Rimworld hours. Weighted average is taken at values in between the defined points. See [[time]] for information on Rimworld time and game ticks.

CurvePoint(100f, 35000f),

CurvePoint(1000f, 30000f),

CurvePoint(5000f, 20000f),

CurvePoint(10000f, 15000f),

The periodic Cerebrex Core attack waves range in potential size from 800 Raid Points of Mechs to 5000 Raid Points. The chart below shows the amount of points for each Mech Birther. So at 10,000 Raid Points, each Mech Birther produces a maximum of 1250 raid points worth of mechs, and there are 4 birthers.

CurvePoint(100f, 200f),

CurvePoint(1000f, 250f),

CurvePoint(5000f, 750f),

CurvePoint(10000f, 1250f),

== Version history ==

* [[Odyssey DLC]] Release - Added.
