Arcangelus: Reduced size of the header somewhat.

{{main|Animals}}
{{Recode|reason=Selectable columns to make manageable table sizes? may run into template size limits.}}
<onlyinclude>
Wild [[animals]] can spawn in specific [[biomes]], whereas almost any animal may be purchased from [[trade]]rs. The following animals: [[Alpaca]], [[Bison]], [[Donkey]], [[Dromedary]], [[Elephant]], [[Horse]], [[Muffalo]], [[Yak]], can carry items in [[Caravan]]s (See [[Pack animal]]).

Animals which produce [[milk]], [[eggs]] and [[wool]] when tamed are listed on the pages for those resources.

This table is only intended as an overview of the most important stats - for more, see [[List of animals/Additional]].

Landmarks

[[File:LandmarkExpanding.png|thumb|right|World Icon]]

'''Landmarks''' are special named generated tiles on the world map that come with features that modify or add to the map when settled. The features may include natural landforms such as lakes, fjords, and atolls, or artificial structures such as abandoned colonies, ancient garrisons, and city ruins. Some features may also be modifiers rather than placed structures, such as higher fertility, fogginess, or higher levels of pollution. Most features can be found in any biome.

== Landmark-defining features ==
Every landmark is associated with a specific feature, or in some cases a set of features. Optionally landmarks can have additional features which can also be found on non-landmark tiles. Features of both types can be searched for with the Search tool, but it only shows results for landmark tiles, settlements and quest sites. Landmark-defining features do not occur on non-landmark tiles.

Landmark-defining features can be combined under some conditions. The primary feature determines the name of the landmark and the way it is drawn on the world map. For example a landmark with the cliffs and lake features will be displayed as a cliffs tile with a cliffs-related name. The primary feature also defines the likelihood of specific additional features to occur. Using the same example, there is no chance of an increased fish feature, which is possible with a lake landmark, because cliffs don't have it.

=== Terrain features ===
Mountain, caves, coast and river are the only features generated in the base game. They have multiple variants in Odyssey.

==== Mountain {{RimworldIcon}} ====
[[File:Mountain in temperate forest.jpg|thumb|Mountain feature in temperate forest]]
''A mountain fills one side of this tile.''

Mountains spawn on mountainous and impassable terrain.

Variants: All mountain variants are landmark-defining features: valley, cavern, chasm, crevasse, plateau, ice dunes, cliffs, hollow, basin, terraforming scar, ancient quarry.
<div style="clear: both"></div>

==== Caves {{RimworldIcon}} ====
[[File:Caves in temperate forest large hills.jpg|thumb|Caves feature in temperate forest with large hills]]
''Small cave networks can be found within the rocks.''

The caves feature only appears on mountainous terrain and large hills, with a 50% chance for mountainous terrain and 25% for large hills. Plateaus have a 40% chance of spawning with caves.

Caves have a chance of spawning with dormant [[hive|hives]] guarded by insects. The amount of caves on the map affects the number of hives: More caves means more hives. Any caves unconnected to the outside are hidden until the player opens a passage, so it's possible to discover dormant hives later in the game.

Hive spawning can be prevented by disabling the generation of natural hives in Custom settings in the Storyteller screen. Alternatively, removing the Insect geneline faction in the Create world screen will dispose of all insect-related content.

Variants: Cave pools, lava caves, ice caves. Those variants don't spawn on non-landmark tiles.
<div style="clear: both"></div>

==== Coast {{RimworldIcon}} ====
[[File:Coast in tropical forest.jpg|thumb|Coast in tropical forest]]

Variants: Headwater, river confluence, river island, delta
<div style="clear: both"></div>

==== Cave pools ====
[[File:Cave pools in temperate forest valley.jpg|thumb|Cave pools feature in temperate forest valley]]
''Small bodies of water can be found within caves in this area.''

This feature creates caves with small deep pools, most of them containing fish.

Cave pools don't spawn on non-landmark tiles. They have a 15% chance to spawn on the following landmarks: valley, chasm, plateau, cliff, hollow, basin.
<div style="clear: both"></div>

==== Lava caves ====

<div style="clear: both"></div>

==== Lakeshore ====
[[File:Lakeshore in temperate forest.jpg|thumb|Lakeshore in temperate forest]]
''This tile borders a lake.''

The lakeshore feature is found on all tiles bordering a lake on the world map. In this context a lake is a small body of water of 15 tiles or less, not the lake feature.

Unlike coastal maps where the water is ocean water, lakeshore maps have fresh water, allowing aquatic plants such as [[reeds]] to grow in suitable biomes.
<div style="clear: both"></div>

==== Headwater ====
[[File:Headwater in desert.jpg|thumb|Headwater in desert]]
''A river's origin point.''

The headwater feature only spawns at the start of a river. Not all rivers have a headwater, some have a lake as their source.

[[File:River confluence in arid shrubland.jpg|thumb|River confluence in arid shrubland]]
''A merging of two rivers.''
<div style="clear: both"></div>

==== River island ====
[[File:River island on huge river in temperate forest.jpg|thumb|River island feature]]
''A river splitting into two and then merging again.''

The river island feature can be found on rivers of all sizes, from huge rivers to creeks.

It has a 5% chance of appearing on a river tile that doesn't already have one of the other river features, i.e. headwater, river confluence, or delta.

Tiles with the river island feature cannot be identified visually on the world map as they have no specific marking and look exactly like standard river tiles.
<div style="clear: both"></div>

==== Delta ====
[[File:Delta of huge river in boreal forest.jpg|thumb|Delta feature in boreal forest]]
''A river splitting into many branches as it enters the ocean.''

Deltas occasionally spawn where rivers meet the sea. Not all rivers end in a delta.
<div style="clear: both"></div>

{{Info|'''Camelhide''' was a type of [[fabric]] gathered by [[Skills#Animals|animal handlers]] by shearing tamed [[dromedaries]]. It was removed in Version 1.1 when the ability to shear dromedaries was removed.}}

== Acquisition ==
Camelhair was acquired by shearing tamed [[dromedaries]] - each dromedary could be sheared every 25 days for 100 wool, for an average of 4 per day.

It could also be purchased from [[trade]]rs.

== Analysis ==
With the best heat insulation of any textile in the game, camelhair was a fantastic option for hot [[biome]]s. Camelhair [[duster]]s could keep you cool in some of the most extreme weather, while [[tribalwear]] allowed apparel sets to focus more on protection in the other layers, while it handled the moderate hot weather.

Protectively, it was mediocre with terrible sharp armor but modest heat armor. Many textiles outperformed it in every way in this niche.

== Acquisition ==
{{Acquisition}}

== Summary ==
{{Stub|section=1|reason= Missing all mechanics - research bonus etc}}

Books in a bookcase provide a [[reading bonus]], improving the speed of [[research]], as well as improving XP gain and recreation from reading.

{{Storage Settings|defaultpriority=Important}}

== Analysis ==
Small bookcases allow storing up to 5 books per tile (more than [[shelves]]), provide a reading bonus, and are cheap, so they should be used if any amount of books are in the colony. If the recreation room and laboratory are different rooms, one or the other will have to be chosen. Combining them is possible, but such a room can't also be a workshop, bedroom/barracks, or [[throne room]]{{RoyaltyIcon}} without a research penalty.

Bookcases built of non-flammable materials will protect the books inside from fire, so stone is an ideal choice.

A regular [[bookcase]] takes the same time and resources to build as 2 small bookcases, so they are practically identical other than their size. Small bookcases are a smaller loss in case of a targeted tantrum, but bookcases are worth little in any case.

"Mid-game" is the phase of an established colony working towards the research and resources necessary to build the spaceship. At this point of the game, you want to create a stable community that is self-sufficient and can recover from disaster as quickly as possible. Even a string of bad events should not lead to ruin.

This is the longest phase of a typical playthrough. Your challenge is to keep all basic needs covered and, most importantly, have everybody in a good [[mood]]. The game tries to put your colonists in a bad mood in many ways. Counteracting this is how you avoid crises and increase overall productivity. A lot of the advice in this guide revolves around mood management, either directly or indirectly.

== Buildings and Infrastructure ==

{{main|Colony Building Guide}}

Here is a list of facilities in rough order of importance that an established base in midgame should have – all of this ''heavily'' varies by difficulty level and map conditions (but you will know when your defense was too weak for your difficulty level...).

* '''Power supply''': the power supply must be sufficient to run all essential facilities, including lighting. Some backup (such as offline batteries) should be on stand-by. Since power is critical in some areas (e.g. to run the freezer) it must not be easily interrupted by damage; that means, run some backup power lines.
* '''Freezer''': a refrigerated room that is large enough to hold enough fresh food to get you through the winter or special circumstances like a [[toxic fallout]] event. How much food you need to store depends on a lot of other factors.
* '''Kitchen''': a place to prepare food. This is critical to any colony; the kitchen must be well maintained and in an accessible place.
* '''Food production''': some capacity to farm vegetables (e.g. an outdoor farm with some protection from fire and animals, or an indoor hydroponics facility). How much is needed depends on the amount of meat available from hunting, and if you have domesticated animals yielding products. You also want to farm medication and various drugs, in addition to food.
* '''Warehouse''': a storage area that is reasonably fire-proof and easily accessible.
* '''Living''': good living conditions for your colonists. This usually means private bedrooms for everybody, and all colonists with special needs ("greedy", "jealous") covered, as well as a dining and recreation area. All of this should be as comfortable and beautiful as possible.
* '''Hospital''': at least a few beds in a clean room to tend patients. Preferably the room should be sterile and include hospital beds and vitals monitors. A stockpile of medication should be in this room.
* '''Defenses''': facilities adequate for your difficulty level to defend you from raids. This can range from a few walls to heavy fortifications and automated turrets.
* '''Production''': a dedicated area for crafting and creating. This should be close to the warehouse, and made as comfortable and beautiful as is reasonable.
* '''Prison''': if you get a lot of "visitors", some decent accommodation (a.k.a. brig) is in order. The prison cells should be comfortable enough to keep the prisoner as happy as possible, because that makes recruiting them easier. Consider creating extremely small and uncomfortable cells for prisoners who you would like to Convert to your Ideoligion, because pawns with low mood lose Will and Certainty faster.
* '''Prison''': Alternatively, you can use prisons as an experience farm by making it so the guests revolt as often as possible. Stack those mood debuffs to the point where they have mental breaks while in catharsis from the last one to get Medical, Combat, Social (via Wardening) and Construction experience in much higher amounts than you would with a "nice" prison since your guests stay much longer before you can break their will, then recruit or release them.

In general:
* All areas should be well lit (no dark places).
* Frequented areas should have constructed or smoothed floors.
* [[Autodoor]]s should be used in frequently trafficked places (the kitchen, freezer, storage and production room).

Do not strive for perfection in any of these areas yet. It is better to have a makeshift hospital than none at all; so make a room with a few beds that are only used for medical purposes, before thinking about hospital beds and sterile tiles. The important point is to have medical beds on stand-by, in a clean room, at all times – not to have the perfect end-game hospital right from the start. Likewise, keeping a small, ugly, insecure prison barracks is still better than having to re-purpose rooms after every raid in order to even capture somebody (leaving some colonists without bedrooms in the process).

Create the basic facilities first, then improve them afterwards. Do not take unnecessary shortcuts (for example, do not put the butcher's table in the medical room, because "there just was no better spot at the moment"). By the midgame you should strive to have everything built out of stone.

The kitchen, hospital and laboratory (research benches) can be placed in the same room, which should be sterile. This is because room cleanliness has a major impact on cooking, medical outcomes and research speed. Moreover, both the kitchen and hospital benefit from being in a central location, and the mood impact from waking up a pawn during treatment is pretty minor compared to the impact of acute pain.

Make all rooms as cozy and beautiful as possible, especially the areas where your colonists spend a lot of time: research desks, workshops, and recreation rooms. A beautiful environment will lift up their mood; build beautiful objects anywhere your colonists spend a lot of time, not simply the recreation area. Putting good chairs in front of all production desks will make your colonists feel comfortable while they are using them.

Rooms and corridors must be spacious enough to not cause problems and allow your colonists to move around freely. Leaving a little extra room is almost always a good idea. While one-tile corridors to infrequently used locations are fine, you will probably want at least two tiles for the major travel paths.

{{clear}}

=== Freezer ===
[[File:Special freezer.png|thumb|right|This freezing room has the coolers placed in the center instead of at the edges. Only the center tile is unroofed. The green area shows the roof, this is also the "cold" area of the freezer room. The center, unroofed, tile is at outdoors temperature.]]
[[File:Freezer example.jpg|thumb|right|A double-walled freezer with a single airlock entrance.]]
Even in the early game, the freezer is an indispensable facility, because meat and prepared meals spoil very quickly, and it is impossible to keep a fresh food stockpile without a controlled freezing area.

In the mid-game, you must make sure that your freezer is large enough to store enough supplies for the entire colony, and possibly many days. The freezer must be close to the room where meals are prepared. Since unbutchered animals are usually stored inside the freezer as well, it is viable to put the butcher's table ''inside'' the freezer. This also keeps the substantial filth from the butchering in a room where it does not matter. Butchering is a short, intermittent activity for your cook, so the work speed penalty is not very impactful here.

If your freezer opens directly to the kitchen, your kitchen might end up cold. If your freezer opens directly on the outside, it can lose coolness, particularly during heat waves or solar flares. You may consider building a small freezer vestibule / airlock to limit this effect.

=== Kitchen ===
[[File:Kitchen area.png|thumb|right|Kitchen area with short walkways for the colonists and separate meal freezer. This layout tries to minimize foot traffic in the kitchen, but it is difficult to avoid. Haulers need to be able to take leather from the freezer to the warehouse, without walking through the kitchen – this is not shown in this layout.]]

By midgame usually you will have at least one [[electric stove]], and possibly some temporary storage shelves for cooking ingredients.

At some point, you should replace the floor in this room with metal or even sterile tiles. This will reduce the chance of [[food poisoning]], a very annoying condition that you want to avoid.

In any case, the kitchen absolutely needs to be close to the freezer, probably right next to it. The connecting door is also probably the first [[autodoor]] you should build in your base.

Prepared food has to be delivered to your dining area, and often also to prisoners and hospital patients. Position the kitchen so that this is easily possible. The kitchen door should probably be an [[autodoor]]. When the colony grows larger, you should create a secondary, small freezer room close to where prepared meals are consumed. Then do not store meals any longer in the freezer. This will reduce foot traffic in the freezer, and make it a lot easier to have colonists eat at a table. The popular ''Rim Fridge'' mod helps with this approach.

=== Bedrooms ===
[[File:Bedroom.png|thumb|right|General purpose bedroom, suitable for all phases of the game. Temperature is equalized with a hallway to the right. The room has enough space for a temporary production building.]]

Bedrooms have a high impact on the overall mood of your colonists, so it is worth investing in them. Higher quality beds make your colonists rest more quickly during sleep, increasing their productivity (work hours per day).

A good midgame bedroom needs to be ''impressive'' and provide a ''comfortable'' bed.

* To increase comfort, give the bed an [[end table]], and put a [[dresser]] in the room. Higher quality furniture provides better comfort, while higher quality beds increase the ''rest effectiveness''. Have your most capable builder furnish the bedrooms.
* Overall [[Room stats|impressiveness]] of the room is a complex [[Room stats|combination]] of several factors: ''wealth'', ''room size'', ''beauty'' and ''cleanliness''. Provide a good balance of all these qualities.
* A good midgame bedroom has all of the following:
** 25 tiles of floor space; bigger is not good, because it increases cleaning effort and cost of flooring. This leaves enough room to put temporary production buildings in the bedroom, useful during base expansion.
** Bed, end table and dresser in best possible quality
** Standing lamp
** Beauty items, such as flower pot or sculpture; more is better, but do not go overboard.
** High quality flooring, such as carpets. This increases beauty. If you can smooth the floors (and walls), usually in a mountain base, this is always preferable to carpet flooring: it gives the same beauty value, but is not flammable and much cheaper to build. You need a good constructor, because smoothing floors takes a lot of work.
** Heating and/or cooling; it is far easier to heat or cool the hallways instead, and use [[vent]]s to equalize the temperature with the bedrooms.

Keep the bedrooms clean, because dirt quickly lowers "impressiveness".

It is ''not'' recommended to have a table and chair in the room for colonists to eat at, because other colonists will use it as well, and possibly disturb the sleep of the owner. Put the eating tables in the hallway in front of the bedrooms if you have to.

Bedrooms should only have a single door, so they will not be used as a thoroughfare, disturbing the sleep of their owners.

=== Hospital ===
[[File:Compact hospital layout.png|thumb|right|A highly efficient hospital layout. Dresser and end tables provide maximum comfort. Two vitals monitors cover all 8 beds. Flatscreen TVs provide extra recreation for the patients. Medical supplies are close by, the room is well lit and accessible from all sides. The vents equalize room temperature with the hallway (climatize as needed). Up to six more beds could be installed here rather easily: four in place of the end tables, and one each to the left and right of the vitals monitors; all beds will have dresser, TV and monitor coverage.]]

A hospital room should have [[sterile tile]] flooring; they provide a cleanliness buff that increases surgery success rate and lowers wound infection chance. [[Hospital bed]]s and [[vitals monitor]]s boost treatment quality and immunity gain. One vitals monitor can cover up to 8 hospital beds in the most effective layout.

Bedridden colonists have no access to recreation outside of "solitary relaxation" and "social interaction" with other colonists. This can be alleviated by placing TV sets in range of the hospital beds. Colonists sleep facing to the right, so in order for a TV to be usable by the patient, it has be either "south" or "east" of the bed (with the head rest being "north").

The quality of the hospital bed increases both rest quality and treatment quality. It is advised to have only your most capable construction workers make hospital beds.

[[Dresser]] and [[end table]]s ''do increase'' the comfort of the hospital bed. The furniture does not affect medical treatment, but improves the mood of the colonists while they are recovering. The downside is that each end table blocks a spot with vitals monitor coverage, but this is not a problem until one needs to squeeze the absolute maximum number of beds into the hospital.

It is good for the hospital to be "spacious" and "beautiful", because the mood benefits will apply to patients, who usually spend a fair amount of time in the hospital room.

Keep your medicine stockpiles close to, or inside the hospital room. Put them on shelves to eliminate the beauty penalty of the stockpiles (it also looks better).

Due to patients usually being "in pain", and therefore being in poor mood (unless they happen to be ''masochists''), a [[psychic emanator]] is very beneficial if you can position it to cover your hospital beds (this item is only available as a quest reward).

==== Using hospital beds as sleeping spots ====

Note that hospital beds can be regular sleeping spots for colonists or prisoners. They are marked as "medical" beds by default, but can be marked for colonist or prisoner use just like a regular bed (however, turning the entire hospital into a prison is normally not viable).

Use this to your advantage. You will normally have more hospital beds than you need, and they happen to be high quality beds in a comfortable environment. If you need an extra prison cell, for example, convert the bedroom of a happy colonist into a prison cell and repurpose one of the hospital beds for the colonist.

=== Recreation and dining room ===

In the early game it is usually not viable to divert much time and resources to recreation, outside of a horse shoes pin in the sand, and a table with a few stools in the kitchen.

In the mid-game, this changes, and your growing colony demands good entertainment and a civilized dining experience.

Any room with a table and chairs, and a food source close enough can be a "dining room". However, it is efficient to combine this with the recreation area. Having an impressive room for dining and recreation gives a mood buff that lasts through the day. If you arrange for your colonists to eat in the recreation hall, you only have to invest in ''one'' impressive room instead of two.

Unless you use mods (such as ''Rim Fridge'' and the ''TD Enhancement Pack''), it can be tricky to motivate your colonists to take their meals in a dedicated room. Your best bet is to place the source of food (usually the freezer room) as close as possible to the next available table – which should be in the recreation hall. It can even be viable to create a dedicated, small freezer room right next to the dining room, and store cooked meals exclusively there. This will also greatly shorten travel times of your colonists, because grabbing meals is such a common action.

The recreation room needs to be fairly spacious, and it should house all the recreation items that your colony can afford. Usually at least a 12x12 (or larger) area is required. It should also ''not'' be the central room in your colony, because it is infrequently used and not critical for colony operation. Having your colonists walk through, or around this room many times per day is very time consuming.

Make this room as impressive as possible. Put your great works of art there, have it well-lit and clean. The room will be used by all colonists, every day, so every mood improving effort there is very effective. It is good to have an outdoors recreation area as well (to reduce the ''cabin fever'' debuff on some colonists), but outdoors recreation is limited in an unmodded game.

The recreation room is the fun room, not only for the colonists, but also you, the player. It is the king piece, have fun with it and make it awesome.

Having production or research buildings in this room does ''not'' lower its recreational value (as long as no dirt or clutter comes with it). In fact, it can be a good idea to have buildings like the research bench, art bench, and other production buildings in this room – at least temporarily. This is economical, and makes good use of the mood benefits that come with this area of your base.

=== Workshop ===
You may need to expand your workshop to accommodate more workbenches.

It is an excellent idea to put decorations such as sculptures inside the workshop, as a beautiful environment gives up to +15 mood, improving colonists' productivity.

Store frequently accessed resources near busy workbenches using shelves, so your skilled pawns aren't wasting their time crossing the map to deliver items. You can direct the output to a small, single-tile output stockpile next to the workbench with priority "Low," so that your haulers will remove the item to a more permanent location that does not impact beauty. These shelves can be shared; a cloth shelf is of use both for medicine production and tailoring.

=== Power ===
==== Renewable power ====
[[Geothermal generator|Geothermal power]] is an important source of power from mid-game onward, as it is constant and high-powered. You will need to research Geothermal Power first before you can unlock it, and the generator itself is quite costly (though affordable in midgame). However, once researched and built you can have a constant power supply; you can even have some excess power until lategame. [[Watermill generator|Water generators]] have similar advantages and drawbacks, but are only possible on certain maps.

Make sure your generators and their connecting conduits are well-protected as they often have to be placed far from base. Take care, however, not to enclose your generator within a room without supplying ventilation to the outside.

==== Biopower ====
[[Boomalope|Boomalopes]] can provide tremendous amounts of [[Chemfuel|chemfuel]] power with a large enough herd, as well as being more labor-efficient than burning wood or plant-based biofuel. However, this requires a biome that supports easy grazing space, so it will not be possible everywhere. It also takes some work to milk and haul the fuel. Most seriously, fuel stockpiles should be placed and fireproofed carefully, unless you want to detonate your entire power station at once.

=== Laboratory ===
You may want to have a room dedicated to research, with [[hi-tech research bench]]es, [[multi-analyzer]]s to increase research speed and unlock new research, as well as sterile tiles to keep the room clean, increasing research speed. This room should generally only have one door, lest pawns path through it and leave behind unnecessary dirt.

(If you do not have sterile tiles, at least make sure it has a finished floor.)

=== Prison cells ===

[[File:Prison_example_midgame.png|400px|thumb|right|Mid-late game prison blocks, partially filled. Each cell has a table with a chair, a bed, decorations and a chess table with a chair (for aesthetic purposes). Generosity like this is well-appreciated and rewarded with prisoners joining your colony. Note that the doors open towards the rest of the base (downwards).]]

Like colonists, [[prisoner]]s will also suffer from the mood penalties associated with being kept together in a prison barracks. In addition, prison breaks are also more serious should they happen, for every prisoner locked up in the same room will simultaneously break out, while prisoners in different cells may choose not to join. Thus, keeping them separated improves safety.

Each cell should have a table with a chair, a bed, and a light source. This is the bare minimum you need for a prisoner to be decently kept. Decorating the cell and making bigger cells also increase mood bonuses for easier recruitment. They can't use any joy items put in the cell, but you can add them anyway for a better cell.

Prisons should have doors facing towards your base, so that escaping prisoners will go towards your base instead of away, giving your wardens time to deal with the break. A small vestibule with an extra door will also slow them down.

If you have only one prison barracks, be certain to check your prisoners' gear, as they are more likely to attempt a prison break while well-armored. If a prisoner is wearing armor, strip the prisoner with one of your pawns, then forbid the clothes which you wish your prisoner to keep so that they are not hauled away (the prisoner will ignore this designation and put the clothes back on). You may reuse, recycle, or sell the armor you capture this way.

=== Backup facilities ===

Create redundancies for important facilities of your base.
* Power can be stored in disconnected batteries. They will discharge at 5W, which will deplete a full battery over 120 days. Either put the reserve batteries behind a switch, or keep them disconnected in a stockpile. Their main use comes immediately after a short ("[[Zzztt]]..."), when all main batteries will be completely empty, often leading to a brown out if you depend on wind or solar energy.
* Strategically placed stockpiles of wood can provide backup heating during a solar flare or cold snap. Mark these wood stacks "forbidden", so your colonists will not use them during regular operation.
* Since electric stoves do not work at all during a power failure, it can be useful to have a fueled stove as backup. If some of the food in your freezer is about to go bad during a solar flare, this will allow you to quickly cook some meals and extend the shelf life of the ingredients.
* Critical power lines should be run twice, so in case of damage (or accidental deconstruction) there is no complete power failure. This is especially important around power sensitive areas like the freezer, a hydroponics bay and the power generators themselves.
* Nutrient paste dispensers are very useful if you unexpectedly run short of cooked meals. This can happen for a variety of reasons, such as a sudden influx of prisoners, or your cooks becoming incapacitated.
* There should be a spare room in your base with a couple of beds. This can be used as an overflow bedroom or makeshift prison. At the bare minimum you should have a couple of bedrolls in storage. They are very quick to craft, the leather quality does not matter, and they are useful for caravans as well.

=== Clean room ===
[[File:Sterile room compact.png|thumb|right|Space efficient clean room with kitchen stove, 8 hospital beds with vitals monitor and TVs, and two hi-tech research benches with multi-analyzer. The room is (rated) beautiful and well lit. Note that two TV sets are needed to cover all beds. The freezer is accessible while minimizing foot traffic in the clean room. This structure should be at the edge of the base.]]

There are three structures that benefit from room cleanliness: the kitchen stove, the research bench and hospital beds. It is therefore economical to place these buildings into a room with [[sterile tile]]s. The research benches can be torn down for the end-game and replaced with more hospital beds.

If the room is sterile, the output from research benches is amplified by 9%. This is a substantial amount of work hours from your researchers, especially because so much time is spent researching over the course of the game. Make your laboratory sterile as soon as possible for this reason.

The "clean room design" is also efficient logistically, because both the hospital and the kitchen (with adjacent freezer) are well placed near your base's front door, easily accessible from both the inside and the outside. Food supplies need to be carried in, and injured colonists require good access to the hospital when returning from the field. Having the kitchen inside the hospital makes feeding patients quick and easy.

Foot traffic in this room should be minimized to keep it as clean as possible. Make sure your colonists do not have to pass through this room unless they have to do work here. This means that while the room should be close to the main entrance to your base, it should ''not'' be the lobby where everybody has to walk through. It should also be off-limits to colony animals. An adjacent freezer room should have its own access doors, so that bleeding corpses do not have to be carried across the clean room.

(It is, of course, perfectly acceptable to separating out the kitchen, labs or hospital into their own rooms, if you have secured the space and resources.)

==Resources==

Useful resources include:
*[[Medicine]] to heal wounded and sick colonists
*[[Glitterworld medicine]] for successful surgeries
*[[Stone Blocks]] to make your base
*[[Components]] and [[steel]] to make non-primitive things
*[[Plasteel]] for durable constructs and high-end equipment
*[[Silver]] to barter for nearly anything

=== Food ===
Besides plant-based foods, you should also have a source of animal products and meat so you can make better meals for your colonists.

==== Animal products ====
Some female animals produce [[milk]]. They can be milked regularly by a handler to produce their needed milk.

If you want meat you should raise some [[chicken]]s. They rise in numbers extremely fast, laying eggs rapidly and growing in the span of a little more than 1 season. Raising chickens requires some heavy population management but is rewarding if done right.

[[Pig]]s are another good option for livestock and are one of the more efficient animals in terms of food consumed versus food produced. They also have the special advantage of offering free corpse disposal.

=== Agriculture ===
At this stage you should have solved your food problems (mostly). You should have the space to grow a variety of crops to provide other resources. You should start growing [[corn]] because it has the best time to amount produced ratio.

==== Cash crops ====

Three good choices are [[devilstrand (plant)|devilstrand]], [[psychoid plant]]s and [[smokeleaf]].

Devilstrand is an excellent choice as a mid-game fabric, providing good protection and can be farmed. It can net a large amount of silver for every harvest, but it's very slow-growing.

Psychoid can he harvested and made into drugs, which can sell for a lot. Be careful with drugs as colonists with the [[chemical interest]] or [[chemical fascination|fascination]] traits will binge on drugs if given access to them.

Smokeleaf can be harvested and rolled into [[smokeleaf joint]]s which can sell for quite a sum as well. It takes more work to craft, but it's also less dangerous than hard drugs which can cause immediate addiction, but smoking it carries quite some debuffs.

<small>Note: Work Required includes work needed to plant, harvest and craft. Max Profit assumes Social Skill of 20 (90% Market Value)</small>

=== Mining ===
There's only so much metals on the surface, but there's much more beneath your colony.

You will need to [[research]] deep drilling and [[ground-penetrating scanner]] first to use drills effectively. After this, when you put down a [[deep drill]], you can see where mineral deposits are.

Deep drilling should be the main source of steel and plasteel for your colony at this stage onward. It's best to spare the remaining compacted steel deposits for emergency if you find yourself out of steel to build deep drills out of.

=== [[Component]]s ===
You need a large supply of components for building and crafting.

The best way to obtain components is by trading. Call friendly factions to send bulk goods traders, which always sell components. As well, they can buy a lot of your raw materials. Other traders can also sell components at an increased price.

Even after you've researched it, making them at the [[fabrication bench]] is not a good source as it is cost and labor intensive (25 steel and 134 work required for just 1 component). It does train your craftsmen very fast, however, you can consider making some for practice while solving your shortage at the same time.

=== [[Drugs|Drugs & Chemicals]] ===

Once you've taken care of your food supply, you can spare some more land to grow plants to make drugs out of. They can provide a boost to colonists' mood, improve their performance at work, protect against disease or sell for a lot of silver.

Be careful with drugs, especially when you have colonists with the [[chemical interest]] or [[chemical fascination|fascination]] traits; you will have to keep drugs away from them, or they will binge on them and get addicted or die from [[overdose]].

[[Neutroamine]] can only be purchased from traders, and is needed to make [[medicine]], [[penoxycyline]] and [[wake-up]]. Consider carefully how much of each drug you will need when deciding how to use this resource.

==== [[Beer]] ====
Beer is a social drug that improves mood and can provide joy.

To make beer, you need to have Brewing researched. Then, you will need to grow [[hops]]. Next, you will need to build a [[brewery]] and some [[fermenting barrel]]s Your colonists will turn hops into wort, a precursor to beer. They will then haul wort into the fermenting barrels and wait for the beer to be made.

Due to the minimum tolerance to addict, beer can be safely consumed once every 1 day without risking addiction, so long as the pawn has a body size of 1 or higher and their tolerance is not already elevated before starting the schedule. Alternatively if more is drastic intervention is required, a body size 1 human starting from 0% tolerance can drink 15 beers over any time period without risk of addiction. Note however that at least one day without beer is required before the 1/day schedule can be restarted and 15 full days of abstinence is required to reset to 0% tolerance and allow this strategy to be used again.

==== [[Smokeleaf joint]] ====
A social drug smoked to provide joy, and provide a decent mood boost. However, colonists stoned on smokeleaf suffer from quite some debuffs so it's not a good idea to smoke it unless you need it.

All you need is some [[smokeleaf leaves]] and a crafting spot. The process of rolling leaves into joints is quick and easy.

Colonists can enjoy a joint every 2 days without risk of addiction.

==== Psychite ====
A type of drug made from the leaves of the [[psychoid plant]].

Crashlanded starts can research psychoid brewing to make [[psychite tea]]. Tribal colonies start the game with this research. Psychite tea has the same addiction chance as beer and smokeleaf but does not slow movement or reduce consciousness.

Refined psychoid comes in 2 variants: [[flake]] and [[yayo]]. While they provide a good buff to both mood and stats, they are extremely addictive. Besides this, they are highly profitable. Being very light, you can carry lots on a single caravan trip, and net you a ton of silver in return.

==== [[Go-juice]] ====
A synthetic combat drug made at the drug lab. As its description says, it's suited for your soldiers to take a hit before combat to boost their effectiveness.

It's highly addictive however, and soldiers that frequently use it will quickly find that they are hooked to it and will need to regularly take a hit or suffer from its horrible withdrawal symptoms.

While high on it, your soldiers will move faster, shoot and fight better, and also be more durable than normal- they take a lot more damage without going down, because they don't even feel much pain at all. This also means your colonist will have a much higher risk of death as they don't go down safely unless they take serious brain damage or have their spine or leg destroyed.

==== [[Wake-up]] ====
Stimulant drug that improves consciousness and reduces the need for sleep.

It does not provide any mood buffs but it has a lower chance of causing addiction compared to other hard drugs. Each use has a 2% chance of causing addiction. There is therefore no safe dose interval.

==== [[Penoxycyline]] ====
The only medical drug in the game so far. It provides resistance to the [[plague]], [[malaria]] or [[sleeping sickness]].

It can be used every 5 days to prevent diseases from being contracted.

Most useful in tropical rainforests where disease is rife. Not so useful in cold or arid areas where disease is of little threat.

==== [[Luciferium]] ====
A performance-enhancing mechanite concoction. It provides good functional buffs, and given enough time can heal old scars (including dreaded brain injuries) but doesn't help mood at all. It cannot be made and must be bought at traders or found occasionally.

One of its most significant features is that withdrawal from luciferium is fatal and incurable. Luciferium needs to be taken every 6.667 days in order to prevent withdrawal symptoms, and if the need is unmet the colonist will die in a mean of 10 days.

Due to its high price and constant need, at this stage you should only give it to colonists who need to recover from brain injuries or serious scars. Colonists with a destroyed part (e.g. a shot off leg) cannot recover without installing a new part.

=== Smelting ===
Once you've researched the [[electric smelter]] you can smelt weapons or steel slag chunks for metallic resources.

Steel slag chunks are an unreliable and rather uneconomical source of steel. Smelting should serve to get rid of them more than as a major source of steel, except in extreme survival situations. <br>
For melee weapons it's best that you smelt them as this returns more resources than if you sold them. Weapons don't sell well, at only 20% of base value. <br>
Ranged weapons, on the other hand, are best sold. If you smelt them you'll gain less, especially if any components making up the weapon are destroyed. <br>
However, if the weapons are of low quality or are worn-out it's always a better idea to smelt them.

The smelter allows you to destroy non-smeltable weapons but it's best to keep them as you can sell them, even for a paltry price.

== Equipment ==
While in early game you may need to scavenge what equipment you could, or craft some very rudimentary equipment such as [[tribalwear]] or [[knife|knives]]. Now that you're in midgame, however, you should have the ability to manufacture your own equipment. Good equipment means that you stand a chance against raiders, even when outnumbered.

You should have a [[fueled smithy]] or an [[electric smithy]] to craft melee weapons, [[electric tailor bench]] for sewing clothes (faster than a [[hand tailor bench]]), and a [[machining table]] for armor and guns.

=== Apparel ===
You should always craft [[button-down shirt]]s over [[T-shirt]]s, as they provide better insulation and coverage than simply T-shirts. It's always worth it spending a little more cloth than a replacement arm.

In addition, you can equip your colonists with [[duster]]s, [[jacket]]s or [[parka]]s if you need to.
*Jackets provide additional protection against attacks or the cold.
*Dusters provide protection against both heat or cold, as well as additional protection. Has a larger coverage than the Jacket, protecting the neck and legs as well.
*Parkas provide very good insulation against cold, but provide minimal protection. They should only be worn when actually needed.

Devilstrand is the best for protection; though it isn't as protective as [[hyperweave]] (which is hard to find and ''very'' costly), it can be farmed and produced in mass amounts. <br>
Wool is best for insulation.

For your soldiers, you should always have [[flak vest]]s and [[flak helmet]]s. Just this can protect against a large part of the damage taken. If you're short on materials you can always use the [[simple helmet]], which is significantly cheaper though providing less protection.<br>
Melee fighters should have [[shield belt]]s, though these may be harder to obtain as [[uranium]] is rare and raiders don't come with shields that often.

[[Power armor]] should wait until later as it costs a lot, either to buy or to make.

==== Apparel management ====
You can choose which kind of apparel your colonists will wear. Go to the Assign tab then you can change the outfit worn by colonists under 'Current outfit'. You can also go to 'Manage outfits' and change the settings of each outfit.

*'Anything' isn't recommended as your apparel will not be allocated properly.
*'Worker' allows colonists to wear casual clothes, but not armor. Best for your workers who don't engage in combat much.
*'Soldier' allows colonist to wear armor and some clothes beneath them.
**By default, jackets and dusters aren't allowed; you should allow them as they can provide extra protection on top of your flak vests.
*'Nudist' makes them wear nothing other than headgear, and obviously is intended for your nudist colonists only.

Once you set them, colonists will automatically switch apparel when needed. They will switch low-quality apparel or worn-out apparel for better ones.

You can also force colonists to wear apparel. If forced, they won't replace it automatically; you have to manually direct them to remove them. Choosing 'Clear forced' in the Apparel tab clears the forced status on apparel allowing colonists to replace them if needed.

=== Weapons ===
Obviously, you should give your best fighters your best and most skill-based weapons.

For guns:
*[[Bolt-action rifle]]s are good for long-ranged combat in midgame. [[Sniper rifle]]s are more niche due to their low DPS but longer range.
*[[Assault rifle]]s are suited for gunning down mid-long range targets, when handled by good soldiers.
*[[LMG]]s can mow down clustered targets at medium range. Best served in the hands of mid-skilled colonists.
*CQB weaponry such as [[Heavy SMG]]s or [[Pump shotgun]]s are optimal for regular workers for self-defense.
*[[Chain shotgun]]s are not an effective weapon choice on its own due to their horribly short range. However, their high damage output makes them excellent against grouped targets. If you do not have many guns, you can use them to fend off melee warriors who come uncomfortably close to your defenses, but you will have more operational flexibility with other weapons.
*[[Minigun]]s excel at point-blank destruction or crowd control.
*[[Machine pistol]]s are quite common and an excellent choice for training poorly skilled shooters; while their range is poor, they are more accurate, and any friendly fire will be less damaging.

Note that it's best that you hold off crafting guns until you have a steady supply of components, as crafting them can quickly chew through your stock of components.

For melee:
*[[Longsword]]s are the must-have weapon for melee colonists, being the highest damage dealing melee weapon in the game.
*[[Mace]]s are cheaper and deal blunt damage. It's also more effective at fighting armored enemies as most armor protect poorly against blunt trauma.

=== Prosthetics & Organ Replacements ===
By now you'll probably have colonists missing fingers, toes, arms, legs or other body parts (especially captured people, prone to have lost limbs in combat). If you can you should get a replacement for them. All prostheses except the peg leg can only be bought from traders in the base game.

All prostheses heal like normal limbs, but do not bleed and never scar.

==== Peg leg ====
Your humble peg leg is for replacing a missing foot or leg. All you need is 1 log of [[wood]], medicine and a doctor. At 60% efficiency, it's good for getting a colonist back up and running but not good for anything else. This should only be used if you can't afford better.

==== Simple prostheses ====
[[Simple prosthetic leg]]s work at 85% efficiency, making it good for replacing a few missing toes. <br>
[[Simple prosthetic arm]]s, in comparison, work at 50% efficiency only; it should only be used to replace a missing hand or arm.

==== Bionics ====
All bionics have 125% efficiency, making them superior to normal parts.

[[Bionic leg]]s give +12.5% moving; two of them means a total of 125% moving. Good for caravaneers, kiters, first respondents or anyone who needs to move fast.<br>
[[Bionic arm]]s give +12.5% bonus to manipulation; they are good at a large variety of tasks, from shooting to mining to crafting. If you are relying on your colonists to produce components and advanced components, give these crafters bionic arms to speed up their work so that you can produce more bionics.<br>
[[Bionic eye]]s give +12.5% on average to sight; it's the only eye replacement so far, meaning you will have to depend on it to replace colonists' missing or damaged eyes. Sight isn't very important for most tasks, with bonuses from sight capping at 100% sight for most tasks (except medicinal or combat tasks), meaning that enhanced sight is obsolete in many cases. Shooting however relies greatly on sight, so you may consider giving your gunners (especially snipers or marksmen) bionic eye replacements before they actually need them. Melee also depends on sight but the impact isn't so large.

==== Combat hands ====
[[Power claw]]s are a good hand replacement for front-line combatants. It incurs a small manipulation penalty, but greatly increases unarmed damage, to the point where it can even rival a normal or good plasteel [[longsword]].

==== Organs ====
You can buy natural organ replacements from traders, or brutally harvest them from colonists and prisoners. Harvesting them gives a mood penalty for the whole colony (except your trusty [[psychopath]] colonists), a dire mood debuff of -30 to the victim, and also affects Factions relations between yours and the one the victim belongs to. So think twice before harvesting organs from anyone. Never harvest from colonists unless in the direst of situations.

As of 1.0 the only organ replacements are the [[bionic heart]] and [[bionic stomach]], though mods exist to add more bionic organs in-game.

== Combat & defense tactics ==
When you are outnumbered, thinking smart with your combat tactics is also key to not losing colonists.
It's also worth checking out [[Defense tactics]] with more in-depth detail in defensive strategy, [[Defense structures]] for building defenses and [[cover]] for how cover works.

=== Turret mounds ===
Sometimes sandbags and your colonists alone are just not enough. Building "turret mounds" around the map in strategic locations can decimate a good number of raiders before they even get to the colony. Turret mounds are built on a 3x3 block of land:
<pre>O#O
###
O#O</pre>
Where O is a turret and # is a stone wall. Remember, however, that [[turret]]s can be a bit expensive to build and repair. They also require a lot of electricity, so try hooking them up to a wire which is remotely turned on to save your batteries.

Note that you will have to sacrifice some turrets this way as raiders often target the turrets before your colonists due to proximity.

===Diffusing your opponent===
Don't be too arrogant when facing a bombardment of arrows and [[pila]] - each can deal almost an equivalent amount of damage as a [[bolt-action rifle]]. Diffusing your opponent consists of separating the melee attackers from the ranged, and dealing with each of them with your melee and ranged colonists.



===Fighting in the small numbers===
Once you have diffused your opponent's army, their forces will trickle towards you slowly so you can easily deal with each one alone.

====Kiting====
Kiting is the method of using a colonist as bait for an attacker to run towards, and a second colonist taking shots off while the attacker is focused on the first. It does not work if the raider has a shield belt that protects them from bullets. Note: Colonists incapable of violence can still act as bait.
<pre>
R
C |
v
C
</pre>
Diagram of kiting. C is a colonist, R is a raider and -> is the direction the raider is going.

====Splitting====

When two of your colonists are being chased by one person and your weaponry is significantly poorer than the attacker's, you can conduct a split so that the enemy can only chase and down 1 colonist while the other escapes. If one of your colonists has ranged weapons, then you could split and then conduct a kite.

====Rushing====
Rushing is the tactic of sending your best melee attackers to finish off the ranged attackers at the back. The ranged attackers who do not succumb to the attention suppressor could be a pain for your own ranged forces, so it's best to send your melee colonists with [[shield belt]]s to distract the ranged attackers. Before battle, hide your melee attackers behind a nearby hill outside your base so that they remain hidden until all enemy melee attackers are engaged with either the walls or your ranged.

== Colonist management ==

=== [[Training]] ===
[[File:Work priority example.jpg|thumb|Manual priorities for a modestly sized colony. Priorities will often need to be adjusted based on circumstances.]]
You can now dedicate more time to train your colonists' skills so they can perform better.

One way of training them is to have them dedicate all their time to a single task only. In the 'Work' tab, have them prioritize the job type you want them to be good at. Set the priority to 2 and prioritize other more vital tasks (such as Patient or Doctor for medics) at 1.

=== New colonists ===
With more colonists in, the chance of you getting wanderers or escape pods become much rarer. From midgame onward, capturing and recruiting prisoners becomes the main source of new blood. Occasionally, you will still see slaves for sale, wanderers, escape pods or chased refugees, but don't count on them.

==== Attacking enemy bases ====
{{for|a more comprehensive list of strategies|Offense tactics}}

However, now that you have more colonists and better equipment, you have a new option to getting new blood: attacking enemy faction bases.

To do so, create a caravan with your soldiers, food for the journey and medicine to treat the wounded. Once the caravan is ready, set it to go attack an enemy.

Once you succeed in destroying the base, you will be given 24 hours to treat the wounded and rest before your caravan packs up and leaves.

The journey usually takes days so remember to bring enough food. There will also be people and turrets guarding the base so you should have enough soldiers. 12 well-equipped soldiers should be enough to take down any base without much problem, though sometimes you will still lose someone. The base also has food, drugs and medicine. They always have some food, but don't count on them having enough medicine to treat all your injuries.

Sometimes an enemy outpost event will also trigger, generating an outpost that is weaker than a standard base. Defeating this requires less manpower (around 8 will be sufficient) and will allow you to collect payment.

Note that attacking enemies does not seem to make raids happen less often and you will still need defenders back at base.

== [[Animals]] ==
Besides raising them for meat, wool or milk, you can train an animal army for attacking, or a worker band for hauling. You will need food to train animals, which you can easily provide in midgame if nothing bad happens.

Hauling becomes a rather important job in midgame as you gather more and more resources and thus need more manpower to haul them to your warehouses, but can't divert colonists from other jobs to haul.

For offensive purposes, there are a few choices available.
*[[Wild boar]]s are a decent choice, despite being nerfed somewhat in the latest versions of RimWorld. They hit reasonably hard, reproduce fast allowing you to amass a large army easily, can graze, and are found in many biomes.
*Ostriches are another good pick. They hit hard, are faster and more durable.
*Taming [[cougar]]s, wolves or bears provides great combat power, but will require a constant source of meat to train them.
*Elephants or rhinos are very durable and hit hard individually, though their large size also makes them be hit much more often.

== Mobility ==
Sometimes you will need to move around the world for various reasons, such as attacking an enemy base, trading at a faction base or starting a new base.

=== [[Caravan]]s ===
You can get a group of colonists to form a caravan to travel around the world.

Caravans have a weight capacity which determines how much each character can carry. Each colonist or [[alpaca]] carries 35 kg at most; [[muffalo]]s can carry up to 73.5 kg, while [[dromedary|dromedaries]] carry 70.

Caravans are somewhat slow, taking days, or sometimes seasons to reach their destination; remember to pack enough food that does not rot easily. Animals that can eat grass/ other plants do not need food when grazing is available, but all others do. You can speed it up by having faster colonists or animals such as [[horse]]s in the caravan, this brings up the average speed of the caravan allowing it to travel faster.

Sometimes hostile random events can occur such as an ambush; remember to bring a suitable escort if needed.

=== [[Transport pod]]s ===
This method is extremely fast; it takes up to 1 in-game hour at most to reach its destination.

However, it's also expensive; each pod costs 80 [[steel]] and 1 [[component]], in addition to the [[chemfuel]] required to power it. It also requires research before it becomes buildable. [[Chemfuel]] can be produced by researching Refining, allowing the construction of a Refinery that refines chemfuel using wood or organic matter.

Each pod carries 150 kg, just enough for 2 barely clothed humans. If colonists land on an empty tile they will form a caravan. Remember to take into account the carrying capacity of its members as if you put too much inside the pods, the colonists will be unable to carry it all, and will be immobilized.

[[Transport pod]]s are best used for urgent missions, but these are uncommon unless you have yourself badly delayed by troubles at home. Some mods provide events which benefit from fast arrival. (For instance, quickly launching a few soldiers and a pack elephant to a wealthy base in the Real Ruins mod will leave you facing fewer raiders than if you took two days to arrive on foot.)

==== Crossing oceans ====
Unfortunately, there's no way to navigate over the deep sea. If you happened to have chosen your starting point on an island (intentionally or not), the only way to get to the mainland is by launching transport pods. You will need to construct additional transport pods in order to return; this can be done with [[steel]] mined on site if you send [[chemfuel]] for the return trip.

== Trade ==

You can travel around using [[caravan]]s, as well as [[transport pod]]s. This greatly opens trade opportunities and enables the player to command multiple colonies (options) at once. It also raises the importance of [[Silver]] and economics in the game, as well as, inevitably, [[drugs|drug trafficking]].

For the average colony, earning money mainly relies on either cash crops like [[Smokeleaf]], stone [[sculptures]] or the brutal treatment of [[prisoner]]s. It is important for every colony to select at least one of these options as their main income source, to obtain important resources like [[Steel]].

With the [[comms console]] you are able to call factions to send traders to visit your base. It's better to do so than wait for them to send traders on their own, as they rarely do so without being prompted.

You should also send your own caravans to friendly bases for trade, as they are considerably better-stocked than their traders, and also offer a small discount.

== [[Factions]] ==

Each world has 5 major factions, which you may have already seen before starting (their bases are littered all over the world).

Dealing with them can constitute a large part of running a successful faction.

=== Diplomacy ===
The comms console also allows you to give gifts of silver to factions, improving goodwill.

To do so, call the faction, then select 'Offer gift'. As with trading, select your colonist best at Social to improve the goodwill increase.

Increasing goodwill allows you to call traders at a lower price and to call for immediate military assistance if you need help.

If tribals raid you should pacify them by capturing, healing and releasing their prisoners, as well as gift them. Turning them friendly will stop them from trying to raid your colony with their massive raider forces, which is helpful at long-term survival. You don't want to deal with 100+ angry tribals shooting arrows, throwing pila or clubbing your colonists all at once.

Pirates cannot be reasoned with; releasing their prisoners won't grant any goodwill, they refuse any kind of communication and they live just to make others' lives worse by raiding their bases and stealing their stuff. You can wipe them off the face of this rimworld by destroying ALL their bases but it'll take an immense amount of time.

=== Black Ops ===
Attacking members of other factions will degrade foreign affairs. Foreigners attacked by enraged animals in your territory will affect your relationships, but less.

You can attack a random animal and escape in-between visitors or a trade caravan so that the wild animal attacks them instead of you. If they die, all their belongings become available to you. If some survive, you can medically treat them which counts towards positive interaction between colonies so long as they can leave your map by their own in good health. They won't report any kind of awkward behavior by your people. Have in mind that angry animals due to manhunter will remain roaming until next day, so "saving" them might become difficult, and if there's anybody who is downed but not dead yet, he/she may recover during the night and start moving again. In case the enraged animal is still around, another attack is likely to end the survivor's life for last.

More difficult to perform in Tropical Rainforest biomes or when there's thick snow around due to plants or snow hampering movement.

A '''hidden conduit''' transmits [[power]] from generators or [[batteries]] to appliances up to six squares away. Conduit doesn't block the placement of other structures and isn't blocked by them, so conduit can be placed wherever it's needed, even in walls, except unsmoothed mountain rocks and ores. Hidden conduits differ from power conduits in that they are invincible, invisible, and immune to [[short circuit]]s.

== Acquisition ==
{{Acquisition}}

== Summary ==
{{Stub|section=1|reason=Unique mechanics }}
Hidden conduits transport power. There must be a direct connection to another conduit, [[power switch]], battery, or power source for a conduit to be able to transport power. Electric appliances, such as an electric stove, can link up to a conduit, battery, or generator up to 6 tiles away. Anything with the "Reconnect" gizmo can attach to a distant conduit, but conduits can't attach to a distant conduit.

== Analysis ==
Because of their invincibility, lack of negative impact to beauty, and resistance to [[short circuit]]s they are superior to normal power conduits in every way, though cost double the steel and take 8 times longer to build. Unless truly strapped for steel or labor, they are always preferable.

In the early game, it is possible to connect appliances directly to a generator or battery to avoid having to build any conduits.

'''Biomes''' are types of area on a planet, characterized by their terrain properties, [[Weather|climate]], [[Plants|flora]] and [[Animals|fauna]], [[disease]]s and special challenges. Each world tile has one particular biome. There are twelve playable biomes types in RimWorld, which can be divided into three categories: Warm, Hot and Cold. Oceans and lakes appear as world tiles but are not playable biomes. The [[Odyssey DLC]] introduces five new playable biomes, each with a unique gimmick or challenge.

<div>[[File:World overview.png|550px|World Map]]</div>

The following is a simple summary of the biomes by difficulty, overall cold biomes are more challenging than their hot counterparts.

[[File:BiomeIntensityDiagram.png|750px|Biome Intensity Diagram]]

== Warm biomes ==
These biomes are rich in flora and fauna, and also have a slightly elevated rate of disease. They generally have year-round growing periods, or longer growing periods at the very least. Traveling speed is fast in normal forests and average in dense forests but slow in marshes and during cold seasons if they have one.

=== Temperate forest ===
{{Main|Temperate forest}}
Forests of deciduous trees interspersed with fertile clearings. Many species of animals move around among the trees and on the plains.

[[File:TemperateForest.png|400px|thumb|right|Temperate Forest]]

==== Growing season, temperature, travel and disease ====
* Growing Season: From all year to 20/60 days.
* Average Temperature: {{Temperature|25}} to {{Temperature|0}}.
* Temperature Variation: From {{Temperature|35}} in summer to {{Temperature|-25}} in winter.
* Roads and Rivers: {{Q|Temperate forest|Roads and Rivers}}.
* Movement Difficulty: 1, but sometimes 3 due to winter.
* Forageability: {{%|{{Q|Temperate forest|Forageability}} }}.

=== Temperate swamp ===
{{Main|Temperate swamp}}
Wetlands choked with vegetation and disease. Dense overgrowth makes it hard to move around, and clearing areas for building takes a long time. Much of the terrain is too marshy to support heavy structures.

A more wet version of the Temperate Forest. Like in all swamps, diseases are more common. The marshy soil will probably require [[bridge]]s before constructing buildings and the terrain is really slow to travel, but this biome also has more fertile soil.

=== Tropical rainforest ===
{{Main|Tropical rainforest}}
A thick, moist jungle, buzzing with animal life and infested with disease. Despite its visual beauty, this is a very dangerous biome. Choking overgrowth, aggressive animals, and constant sickness are why some explorers call this the "green hell".

Tropical Rainforests are famous for having many diseases, including [[Disease#Sleeping Sickness|Sleeping Sickness]]: a slow-progressing, long-lasting disease that is exclusive to the tropics. Many trees make it difficult to clear land and rapid plant growth makes it difficult to keep it clear.

=== Tropical swamp ===
{{Main|Tropical swamp}}
A plant-choked, steamy swamp seething with parasites and pathogens. Much of the land is too marshy to build on. Difficult movement, aggressive animals, and rampant disease make living here a nightmare.

A more wet version of the Tropical Rainforest. Like in all swamps diseases are more common. The marshy soil will probably require [[bridge]]s before constructing buildings and the terrain is really slow to travel, but this biome also has more fertile soil. Diseases are even more constant here than in Tropical Rainforests, so making a proper hospital and having good doctors is a priority.

== Hot biomes ==
These biomes become progressively dry as they become more arid. Moderate amount of flora and fauna, which drops off as you pick a more extreme biome. Mostly year-round growing periods. Traveling in those biomes is usually fast and rarely slowed by cold seasons.

=== Arid shrubland ===
{{Main|Arid shrubland}}
A dry region, but not dry enough to become a true desert. Open plains with grasses and bushes give way to scattered groves of trees. Plants are hardy and there is a moderate density of animals, but arable soil is hard to find.

=== Desert ===
{{Main|Desert}}
A very dry area which supports little life. There is very little arable land, and animal life is very sparse. Deserts can be hot, or quite cold.

With so few animals to hunt, growing crops is a priority on one of the few arable patches. The hot temperatures can cause problems for colonists and tamed animals. This biome has patches of soft sand which prevent building, but can be removed with [[moisture pump]]s.

[[File:Desert.png|400px|thumb|right|Desert]]

==== Growing season, temperature, travel and disease ====
* Growing Season: From all year to 10/60 days.

* Roads and Rivers: Yes.
* Movement Difficulty: 1, but sometimes 3 due to winter.
* Forageability: 25%.

=== Extreme desert ===
{{Main|Extreme desert}}
An extremely hot, dry area, devoid of almost all life. Searing heat and a near total lack of arable land make it very difficult to survive here.

The hot temperatures can cause problems for colonists and tamed animals. Its warm enough for growing plants outdoors, but it has to be done in stony patches around hills and mountains. Even though [[potatoes]] grow better in stony soil, you need to plant [[rice]] first so you will not starve while waiting for [[potatoes]]. [[Berries|Strawberries]] are also a good idea since there is no wood for cooking. Later [[Hydroponics basin|hydroponics]] can be used instead of ground. This biome has patches of soft sand which prevent building, but can be removed with [[moisture pump]]s. Animal migrations may occur, about once every other year.

== Cold biomes ==
These biomes become progressively colder and hostile as they become more intense. Flora and fauna becomes more scarce as you pick a more extreme biome. Mostly seasonal growing periods but may go down to no growing period in more extreme biomes. Traveling in those biomes is usually slow due to marsh and cold seasons which can be very long.

=== Boreal forest ===
{{Main|Boreal forest}}
Forests of coniferous trees. Despite the harsh winters, boreal forests sustain a diverse population of small and large animals, and have warm summers.

=== Cold bog ===
{{Main|Cold bog}}
A wetland packed with trees and vines. Much of the marshy land here can't support heavy structures, moving around is slow due to choking vegetation. Disease is endemic in this dense, wet ecosystem.

A more wet version of the Boreal Forest. Like in all swamps, diseases are more common. The marshy soil will probably require [[bridge]]s before constructing buildings and the terrain is really slow to travel, but this biome also has more fertile soil.

=== Tundra ===
{{Main|Tundra}}
These mostly-frozen plains bear almost no trees and little vegetation. There are a few small animals interspersed with large herds of migratory grazers and their predators. Animal migrations may occur once or twice per year.

=== Ice sheet ===
{{Main|Ice sheet}}
Sheets of ice which can be kilometers thick. There is no soil for plants to grow in. The only animals here are migrating to somewhere else - or badly lost.

The only land possible to farm is stony patches around hills and mountains, but they need to be [[heater|heated]] indoors and also have [[sun lamp]]s. You will need to hunt, trade and cannibalize until you get a [[heater]] and a [[sun lamp]]. Later, [[moisture pump]]s can create larger growable areas and [[Hydroponics basin|hydroponics]] can be used instead of ground. Geothermal vents can be used for free heating. With so few animals here, any predators that roam in will become hungry soon and target your colonists and animals.

=== Sea ice ===
{{Main|Sea ice}}
Permanent ice sheets floating on water. There is no soil for plants to grow, no minerals to mine, and almost no animal life.

Sea Ice maps do not have geothermal vents or [[Ruins|ruins]] (except in [[Quests#Ancient_Complex|ancient complex]] sites). [[Deep drill]]s cannot dig up stone chunks and [[moisture pump]]s will only generate more ice, which means it is impossible to grow anything on the ground. You will need to do hunting, trading and cannibalism until you get a [[heater]], a [[sun lamp]] and a [[hydroponics basin]]. It is worth mentioning that Sea Ice was designed to not allow colony building, only to allow traveling in the area, even though it is possible.

Blindsight

2026-03-19T21:25:56Z

Arcangelus: /* Advantages */

{{Ideology}}
[[File:Blindsight.png|64px]]'''Blindsight''' Is one of the memes added with the [[Ideology DLC]].

It elevates the status of blind pawns and improves the psypowers of blind [[psycast]]ers.

==Advantages==

* Blindsight gives up to {{+|15}} mood boost to blind pawns and {{+|30}} opinion from other pawns.
* Increases the [[psychic sensitivity]] of blind pawns by {{Up|+30%}} (in addition to the normal bonus to [[psychic sensitivity]] from low [[Sight]] given to all pawns).
* Allows crafting [[blindfold]]s, which provides protection, cold insulation and {{+|2}} mood boost for sighted pawns.
* Blind pawns stats are unaffected by light and darkness.
* Blind pawns ignore other pawns beauty status.
* Blinding greatly decreases the pawn value.
* Unlocks Medical specialists.

==Disavantages==

* Blindsight gives down to {{--|6}} mood penalty to non-blinded pawns and {{--|5}} opinion from other pawns.
* Blinded and blindfolded pawns are severely limited on the number of activities they can perform effectively.
* Blind pawns ignore rooms beauty status.
* Disables the [[Ideoligion#Darkness|Darkness]] meme.

==Blind psysense: Strong==

[[File:Blindpsysense.png]]

This precept increases the user [[psychic sensitivity]] when blind:
* Blind bonus: {{Up|+30%}} psychic sensitivity.

Regardless of this precept, each point of sight below 50% (before offsets and post factors) gives the user {{Up|+1%}} psychic sensitivity.

That means you normally get:
* Sighted wearing [[blindfold]]: No bonus.
* One-eyed with [[Cataract]]: {{Up|+12%}} psychic sensitivity.
* Total blindness: {{Up|+50%}} psychic sensitivity.

And with this precept:

* Total blindness: {{Up|+80%}} psychic sensitivity.

== Blinding ritual==

[[File:BlindingRitual.png]]

If satisfying or spectacular, this ritual will give the pawn a [[psylink]] upgrade.{{RoyaltyIcon}}

You can repeat the ritual by recovering the pawn sight, that means you can effectively trade [[bionic eye]]s, [[healer mech serum]]s and [[resurrector mech serum]]s for psychic powers. The [[unnatural healing]] creepjoiner ability{{AnomalyIcon}} will also heal an eye every 6 days, using this to repeat the ritual is likely the cheapest source of psylink upgrades available currently, though at the risk of [[flesh tentacle|side-effects]]{{AnomalyIcon}} if the pawn does not already have artificial arms.

You can also heal the pawn eyes in a [[Biosculpter pod]] if they follow a non-Blindsight ideoligion. Together with the Transhumanist's "Biosculpting: Accelerated" this is one of the most efficient ways to farm psychic powers because the pawn doesn't have to be in the Blindsight ideoligion to be the Target of a Blinding ritual.

==Affected activities==

Before blinding a pawn, it is important to consider what activities are affected by [[sight]].

Activities that are not affected by blindness:

* [[Taming]], Training, [[Social]], [[Hauling]], Cleaning and Meditation.

Activities that are slower with blindness:

* Hunting, Cooking, [[Crafting]], [[Art]] and [[Research]].

Activities that have lower yield with blindness:

* Mining, Butchering, Plants, Milking and Shearing.

Activities that might result in failure with blindness:

* [[Construction]] and Medical.

Pawns dedicated to cleaning, hauling, socializing and mediating are the ideal pawns to blind.

If you are only taming and training without milking or shearing anything then animal handlers are also a good option to blind.

Hunters, cookers, crafters, artists and researchers can be blinded with only a reduction in work speed.

Builders and doctors are the worse options to blind since they can result in losing expensive materials, bionics and lives.

==Strategies==
Blinding overall provides more benefits than wearing a blindfold but compromises the pawn fighting abilities while a blindfold can be taken out during a raid. Therefore, full blindness is better suited for pure [[psycast]]ers or pawns carrying [[weapons]] with forced miss radius such as [[EMP grenades]]. Alternatively, careful shooters pawns, shooting specialists and [[Gunlink]]s can help overcome the accuracy lost.

Blinding is particularly useful in [[slaves]]. Blind slaves add very little wealth to your colony and are fairly harmless in case a rebellion happens. They can effectively use [[EMP grenades]], [[EMP launcher]]s and [[Smoke launcher]]s since those weapons don't have an aim penalty from blindness and also don't increase slave rebellion chance. Also, the extra cold insulation from blindfolds might just be enough to allow them wear [[Slave body strap]]s on cold biomes. They will have increased psychic sensitivity and don't use psy powers if they rebel, therefore, the nobles of the [[empire]] which already have some psy powers make really good candidates for blind slavery with support combat roles.

Since blinding is not ideal for a lot of pawns, Blindsight is better used together with another [[Ideoligion]]. That way, you can have a few blinded pawns enjoying the benefits of their blindness without affecting much their activities while the rest follows another ideoligion that doesn't includes Blindsight and therefore are not sad for not being blind. For example, it might be worth it to have a "blind worker" Ideoligion for cookers, crafters, cleaners and haulers and a "sighted elite" Ideoligion for those who need to keep their sight. Only your starting Ideoligion and the ancient's Ideoligion can have Blindsight.

Blind pawns are unaffected by light and darkness, so ideally you should fight in darkness so your enemies get a move penalty and you don't. Consider keeping a Sun Blocker active for a permanent fight advantage if it doesn't hurt your energy and food production.

Blind pawns ignore pawns beauty status, so you can give them [[Stoneskin gland]]s without penalty to opinion.

Blind pawns ignore rooms beauty status, so you won't get negative [[mood]] buffs for dirty rooms, but you also won't get positive mood buffs for beautiful rooms.

It is not a good idea to blind medical specialists, but they can still wear blindfolds while not doctoring and act as psycasters during combat. Unlike pawns incapable of violence, medical specialists can equip an [[Eltex staff]] if you give them before assigning the role.

Even if you don't want to blind anyone, Blindsight is still a useful meme that gives access to medical specialists and the blinding ritual which can be used to farm psychic powers.

For example, it might be worth it to have a "blind worker" Ideoligion for cookers, crafters, cleaners and haulers and a "sighted elite" Ideoligion for those who need to keep their sight. Only your starting Ideoligion and the ancient's Ideoligion can have Blindsight.

Blind pawns are unaffected by light and darkness, so ideally you should fight in darkness so your enemies get a move penalty and you don't. Consider keeping a Sun Blocker active for a permanent fight advantage if it doesn't hurt your energy and food production.

Blind pawns ignore pawns beauty status, so you can give them [[Stoneskin gland]]s without penalty to opinion.

Blind pawns ignore rooms beauty status, so you won't get negative [[mood]] buffs for dirty rooms, but you also won't get positive mood buffs for beautiful rooms.

It is not a good idea to blind medical specialists, but they can still wear blindfolds while not doctoring and act as psycasters during combat. Unlike pawns incapable of violence, medical specialists can equip an [[Eltex staff]] if you give them before assigning the role.

Even if you don't want to blind anyone, Blindsight is still a useful meme that gives access to medical specialists and the blinding ritual which can be used to farm psychic powers.

Blindsight

2026-03-19T21:23:07Z

Arcangelus: /* Blind psysense: Strong */

{{Ideology}}
[[File:Blindsight.png|64px]]'''Blindsight''' Is one of the memes added with the [[Ideology DLC]].

It elevates the status of blind pawns and improves the psypowers of blind [[psycast]]ers.

==Advantages==

* Blindsight gives up to +15 mood boost to blind pawns and +30 opinion from other pawns.
* Increases the [[psychic sensitivity]] of blind pawns by +30% (in addition to the normal bonus to [[psychic sensitivity]] from low [[Sight]] given to all pawns).
* Allows crafting [[blindfold]]s, which provides protection, cold insulation and +2 mood boost for sighted pawns.
* Blind pawns stats are unaffected by light and darkness.
* Blind pawns ignore other pawns beauty status.
* Blinding greatly decreases the pawn value.
* Unlocks Medical specialists.

==Disavantages==

* Blindsight gives down to -6 mood penalty to non-blinded pawns and -5 opinion from other pawns.
* Blinded and blindfolded pawns are severely limited on the number of activities they can perform effectively.
* Blind pawns ignore rooms beauty status.
* Disables the Darkness meme.

==Blind psysense: Strong==

[[File:Blindpsysense.png]]

This precept increases the user [[psychic sensitivity]] when blind:
* Blind bonus: {{Up|+30%}} psychic sensitivity.

Regardless of this precept, each point of sight below 50% (before offsets and post factors) gives the user {{Up|+1%}} psychic sensitivity.

That means you normally get:
* Sighted wearing [[blindfold]]: No bonus.
* One-eyed with [[Cataract]]: {{Up|+12%}} psychic sensitivity.
* Total blindness: {{Up|+50%}} psychic sensitivity.

And with this precept:

* Total blindness: {{Up|+80%}} psychic sensitivity.

== Blinding ritual==

[[File:BlindingRitual.png]]

If satisfying or spectacular, this ritual will give the pawn a [[psylink]] upgrade.{{RoyaltyIcon}}

You can repeat the ritual by recovering the pawn sight, that means you can effectively trade [[bionic eye]]s, [[healer mech serum]]s and [[resurrector mech serum]]s for psychic powers. The [[unnatural healing]] creepjoiner ability{{AnomalyIcon}} will also heal an eye every 6 days, using this to repeat the ritual is likely the cheapest source of psylink upgrades available currently, though at the risk of [[flesh tentacle|side-effects]]{{AnomalyIcon}} if the pawn does not already have artificial arms.

You can also heal the pawn eyes in a [[Biosculpter pod]] if they follow a non-Blindsight ideoligion. Together with the Transhumanist's "Biosculpting: Accelerated" this is one of the most efficient ways to farm psychic powers because the pawn doesn't have to be in the Blindsight ideoligion to be the Target of a Blinding ritual.

==Affected activities==

Before blinding a pawn, it is important to consider what activities are affected by [[sight]].

Activities that are not affected by blindness:

* [[Taming]], Training, [[Social]], [[Hauling]], Cleaning and Meditation.

Activities that are slower with blindness:

* Hunting, Cooking, [[Crafting]], [[Art]] and [[Research]].

Activities that have lower yield with blindness:

* Mining, Butchering, Plants, Milking and Shearing.

Activities that might result in failure with blindness:

* [[Construction]] and Medical.

Pawns dedicated to cleaning, hauling, socializing and mediating are the ideal pawns to blind.

If you are only taming and training without milking or shearing anything then animal handlers are also a good option to blind.

Hunters, cookers, crafters, artists and researchers can be blinded with only a reduction in work speed.

Builders and doctors are the worse options to blind since they can result in losing expensive materials, bionics and lives.

==Strategies==
Blinding overall provides more benefits than wearing a blindfold but compromises the pawn fighting abilities while a blindfold can be taken out during a raid. Therefore, full blindness is better suited for pure [[psycast]]ers or pawns carrying [[weapons]] with forced miss radius such as [[EMP grenades]]. Alternatively, careful shooters pawns, shooting specialists and [[Gunlink]]s can help overcome the accuracy lost.

Blinding is particularly useful in [[slaves]]. Blind slaves add very little wealth to your colony and are fairly harmless in case a rebellion happens. They can effectively use [[EMP grenades]], [[EMP launcher]]s and [[Smoke launcher]]s since those weapons don't have an aim penalty from blindness and also don't increase slave rebellion chance. Also, the extra cold insulation from blindfolds might just be enough to allow them wear [[Slave body strap]]s on cold biomes. They will have increased psychic sensitivity and don't use psy powers if they rebel, therefore, the nobles of the [[empire]] which already have some psy powers make really good candidates for blind slavery with support combat roles.

Since blinding is not ideal for a lot of pawns, Blindsight is better used together with another [[Ideoligion]]. That way, you can have a few blinded pawns enjoying the benefits of their blindness without affecting much their activities while the rest follows another ideoligion that doesn't includes Blindsight and therefore are not sad for not being blind. For example, it might be worth it to have a "blind worker" Ideoligion for cookers, crafters, cleaners and haulers and a "sighted elite" Ideoligion for those who need to keep their sight. Only your starting Ideoligion and the ancient's Ideoligion can have Blindsight.

Blind pawns are unaffected by light and darkness, so ideally you should fight in darkness so your enemies get a move penalty and you don't. Consider keeping a Sun Blocker active for a permanent fight advantage if it doesn't hurt your energy and food production.

Blind pawns ignore pawns beauty status, so you can give them [[Stoneskin gland]]s without penalty to opinion.

Blind pawns ignore rooms beauty status, so you won't get negative [[mood]] buffs for dirty rooms, but you also won't get positive mood buffs for beautiful rooms.

It is not a good idea to blind medical specialists, but they can still wear blindfolds while not doctoring and act as psycasters during combat. Unlike pawns incapable of violence, medical specialists can equip an [[Eltex staff]] if you give them before assigning the role.

Even if you don't want to blind anyone, Blindsight is still a useful meme that gives access to medical specialists and the blinding ritual which can be used to farm psychic powers.

:{{note|Persona|A}} Psychic sensitivity persona weapon traits are mutually exclusive with each other, but not with Neural Cooling. Persona traits appear on the following weapons: [[Persona monosword]], [[Persona plasmasword]], and [[Persona zeushammer]]
:{{note|Sight|B}} [[Sight]] capacity provides is a {{+|1%}} bonus for each percentage point ''below'' 50% sight ''before'' offsets and post-factors. This means [[blindfold]]s and similar items will not provide this bonus, while drugs such as [[go-juice]] will not reduce it. i.e. 20% Sight results in a bonus of {{+|30%}} psychic sensitivity, while total blindness at 0% Sight provides {{+|50%}} sensitivity.
:{{note|Neural Heat|C}} Neural heat limit increase from the increased psychic sensitivity, assuming psylink level 6.
:{{note|Stacking|D}} Note that this stacks with the {{+|50%}} to psychic sensitivity provided just by being having Sight of 0%, for a total of {{+|80%}} to sensitivity and a {{+|64}} to neural heat limit.
:{{note|Bonding|E}} When psychically bonded to a pawn, {{+|10%}} to psychic sensitivity and {{+|8}} to neural heat limit while they are on the same map, otherwise {{+|5%}} and {{+|4}}.
:{{note|Quality|Q}} Value scales with [[Quality]]. 0.5× → 0.66× → 0.83× → 1.00× → 1.16× → 1.32× → 1.5×. Note that Normal quality is not 1.00×
:{{note|QualityBioferrite|QB}} Value scales with [[Quality]]. 1.06x → 1.08x → 1.1x → 1.13x → 1.15x → 1.17x → 1.20x. Note that Normal quality is not 1.00×
:{{note|QualityBioferriteHeat|QBH}} Value scales with [[Quality]]. {{+|4}} → {{+|6}} → {{+|8}} → {{+|11}} → {{+|13}} → {{+|15}} → {{+|18}}.
:{{note|Building|DR}} Each pump stacks additively, up to a maximum of 4 times.
:{{note|Ritual|P}} Despite Psychophagy stating that it consumes the psychic sensitivity of the target, neither the target nor invoker's sensitivity affect the result of the ritual, which is always a flat +50% bonus. The invoker's sensitivity does contribute to ritual quality, which increases the duration of the buff.

Sight

2026-03-19T20:53:49Z

Arcangelus: /* Effects */

{{Capacity
| default base value = 1
| to string style = PercentZero
| description = How well a character can see.
}} Sight affects most colonist stats, with varying impact, though its importance will depend on the pawn's role in the colony. Sight is capped at 100% for many stats, but some combat and medical skills are uncapped.

{{Hover title|Version/1.3.3242|At the time of writing}}, the maximum possible Sight capacity in the core game is 250% with a healthy pawn high on [[go-juice]] and [[luciferium]] with two [[archotech eye]]s installed, while also being infected with [[sensory mechanites]]. With the [[Royalty DLC]] installed, it is possible to reach a Sight capacity of up to a maximum of 325% with the addition of the [[Focus]] psycast.{{RoyaltyIcon}}

== Effects ==
{{Stub|section=1|reason=There are definitely more of these that aren't listed - some to be tested inc. eclipses with the relevant precept, etc}}
Sight has a number of unique interactions with other mechanics, beyond the traditional effects on [[stats]].

Colonists whose Sight's base efficiency is less than 50% gain [[psychic sensitivity]] according to the formula <code>0.5-Sight base efficiency</code>, for a maximum of {{Up|+50%}} psychic sensitivity when fully blind. '''Offsets''' and '''Post factors''' are completely ignored for this. Do note that previous to 1.5, this bonus was based on Sight efficiency instead.

Pawns with 0% Sight:
* Are not subject to the factor from low [[light]] levels on [[move speed]] or on [[global work speed]].
* Will not receive the "Observed corpse" or "Witnessed ally's death" moodlets.{{Check Tag|Other similar moodlets?|Wb the other witnessed death (inc outsider, family) and wb bloodlust?}}
* Do not experience the mood buff from [[aurora]]s, nor from [[eclipse]]s with the [[Ideoligion#Eclipse|eclipse]]{{IdeologyIcon}} precept.
* Do not gain nor lose any [[opinion]] for any other pawn based on their [[Beauty (Pawn)|beauty]] stat.
* Do not lose any [[opinion]] for [[disfigured]] pawns.
* Have the need for [[Beauty#Beauty_need_level|beautiful environments]] locked at 50%, becoming a total non-factor to their [[mood]].
* Cannot [[recreation|recreate]] at a [[telescope]], [[poker table]], [[billiards table]], [[hoopstone ring]], [[books]] or any type of [[television]]. They also cannot skygaze or view art for recreational purposes.
* Gain {{Up|+30%}} [[psychic sensitivity]] if they also have the [[Blind psysense]]{{IdeologyIcon}} precept and both their eyes removed. This stacks with the aforementioned {{Up|+50%}} for 0% sight bonus.

== Affected stats ==
{{#ask: [[Sight Importance::+]]
| ?Health Type = Type
| ?Sight Importance# = Weight
| ?Sight Limit# = Max
| ?description
| format = broadtable
| limit = 100
| mainlabel = Name
| headers = plain
| sort = Health Type,
}}

== Formula ==
The formula for sight is:<br/>
<big><code>'''Sight''' = (Base efficiency + Offsets) × Post factors</code></big>

Base efficiency is the result of combining both eyes efficiencies, with a 75% weight to the strongest eye. There are many way of writing it, but for this section the following will be used:<br/>
<big><code>'''Base efficiency''' = (right eye + left eye)/4 + max(right eye, left eye)/2</code></big>

Offsets are additive with each other.

All factors that affect Sight will be listed below.

=== Base efficiency ===
* Eye efficiency. 100% importance, no allowed defect, no max.
** The game assigns 75% weight to the stronger eye and 25% weight to the weaker, so entirely losing a single eye reduces sight by 25% rather than 50%.
** [[Blindness]]: 0% part efficiency
** [[Cataract]]: 50% part efficiency. Results in {{--|12.5%}} sight for the first eye affected, {{--|37.5%}} for the second eye.
** [[Bionic eye]]: 125% part efficiency. Results in {{+|18.75%}} sight for the first one installed, {{+|6.25%}} for the second one.
** [[Archotech eye]]: 150% part efficiency. Results in {{+|37.5%}} sight for the first one installed, {{+|12.5%}} for the second one.

::{{Sight Part Efficiency Table}}

=== Offsets ===
The following offsets affect Sight.
* [[Sensory mechanites]]: {{+|50%}}
* [[Go-juice]]: {{+|35%}}
* [[Luciferium]]: {{+|15%}}
* [[Tox gas]]:{{BiotechIcon}}
** Mild: {{--|10%}}
** Moderate: {{--|25%}}
** Severe: {{--|40%}}

=== Post factors ===
* [[Blindfold]]{{IdeologyIcon}}: Sets maximum to 20%
* [[Focus]] psycast {{RoyaltyIcon}}: '''x130%'''

== Example ==
If we were to calculate the highest possible value in unmmoded rimworld, we would have:
*Base efficiency:
** Right eye: '''150%''' ([[archotech eye]])
** Left eye: '''150%''' ([[archotech eye]])
*Offsets (total {{+|100%}}):
** [[Luciferium]]: {{+|15%}}
** [[Go-juice| Go-juice High]]: {{+|35%}}
** [[Sensory mechanites]]: {{+|50%}}
*Post factors:

'''Ailments''' are [[health]] conditions that cannot be treated completely using medicine alone.

"MTB" stands for "Mean Time Between", and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

Most permanent ailments are curable with body part replacements or usage of the [[healer mech serum]].

{{Heal Option Table}}

== Chronic ==
Ailments that come with age. Either non-fatal, or progresses extremely slowly towards fatality compared to infectious diseases.

=== Alzheimer's ===
{{stub|reason = "Forget memory" and "confused wandering" mechanics}}
A brain disease usually associated with aging. Alzheimer's disease causes progressive degradation in the ability to think and remember. Patients are known to forget close relatives and sometimes wander around in confusion.

Alzheimer's progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity from when it first appears.

'''Treatment:'''
* [[Luciferium]]: Luciferium removes one randomly selected condition that it can cure every 900,000 to 1,800,000 [[ticks]] (15 - 30 in-game days). Having fewer luciferium-curable conditions will increase the chance that Alzheimer's is chosen, so it can be worth attempting to address any conditions that can be other means. Even with this however, it can take a significant amount of time. Also note that luciferium is a permanent decision - once taken, further doses are necessary to avoid madness and death.
* [[Healer mech serum]]: A healer mech serum will instantaneously heal one condition of the pawn, including Alzheimer's. Which condition is chosen depends on a priority order, with Alzheimer's being a moderately high priority. See the serum's [[Healer mech serum#Summary|condition order]] for details.
* [[Resurrector mech serum]]: Because the resurrector mech serum will replace a destroyed head with a healthy one, it can be used to heal brain ailments, including Alzheimers. Consistently destroying the head can be difficult. With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will do this reliably and safely, but without it, the best way is allowing colonists or animals to eat sections of the corpse, at the risk of consuming the entire body and permanently losing the pawn. Furthermore, no matter how successful the head removal, there is always the risks normally associated with resurrection, including [[dementia]], [[blindness]], and [[resurrection psychosis]]. Note that pawns will initially be incapacitated due to resurrection sickness.
* [[Death refusal]]{{AnomalyIcon}}: Similar to the [[Resurrector mech serum]], a pawn imbued with death refusal can self-resurrect and replace a destroyed head with a healthy one. This comes with the drawback of the pawn losing experience in their skills that happens upon imbuing the death refusal. Pawns resurrected via this method will also have resurrection sickness and a negative [[Mood|moodlet]] upon being resurrected.
* [[Chronophagy]]{{AnomalyIcon}}: As pawns younger than 34 cannot get Alzheimer's, reversing age to younger than that in a Chronophagy ritual will remove it.
* [[Unnatural healing]]{{AnomalyIcon}}: a Creepjoiner with unnatural healing replicates the effect of a healer mech serum and so can be similarly used to cure Alzheimers at the minor risk of replacing an arm with a flesh tentacle for the cured pawn

=== Asthma ===
A chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. Unlike other chronic diseases, asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line.

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity (50%).

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% beginning to regress the stages of asthma (the higher, the better).

{| class="wikitable"

|}

Treatment:
* The severity of asthma can be reduced with treatment, which can be given every 420,000 ticks (around 7 days). One treatment applies to both lungs.
* Asthma can be cured by replacing each affected lung with a [[Lung#Acquisition|healthy replacement]].

A human pawn can first get asthma at any age.

Asthma can also affect animals, domestic, tamed and wild. Domestic and tamed will notify you that they "need treatment", although there apparently is no downside for ignoring that request except slowing them down which may be bad for [[Animals#Training|trained]] or [[pack animal]]s. Similarly, asthmatic wild animals on the map can roam and eat indefinitely without treatment. In fact, wild animals with asthma are easier and slightly safer to hunt, because asthma will reduce their [[move speed]] to 81%, and their [[manipulation]] to only 90%, which makes any counter-attack less effective.

=== Bad back ===
Degradation in the spinal column and surrounding musculature. This makes it hard to move and bend smoothly.

Cataracts can be cured through the following methods:
* Replacing the affected eyes with a [[bionic eye|bionic]] or [[archotech eye|archotech]] eye.
* Use of a [[healer mech serum]] which will heal cataracts in both eyes at once
* Via [[luciferium]] use. Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.
* Through the use of the [[biosculpter pod]]'s bioregeneration cycle.{{IdeologyIcon}}
* Via the [[Scarless]] gene.{{BiotechIcon}} Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.

=== Carcinoma ===
{{Stub|section=1|reason=How do the stages progress/occur and what chances and factors affects them?}}
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumors, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed by a skilled doctor or, in some cases, the affected body part can be removed, either by amputation, transplantation of a healthy body part, or replacement by an [[artificial body part]]. Ordinary treatment will prolong the development of a carcinoma or speed up remission, and can be done by doctors of any skill, though better treatment quality is more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.
* When growing, it progresses by 0.003 per day, multiplied by a random factor of 0.45 - 1.65.
* When stable, it neither grows nor regresses on its own.
* When in remission, it regresses by 0.002 per day, multiplied by a random factor of 0.7 - 1.5.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will:
* grow more slowly when in growing stage
:* some slow-growing carcinomas (something less than half) may stop or actually regress (very slowly) during their "growing" stage with good treatment
* slowly regress when stable
* regress quickly when in remission

* Acute pain (+60%)
* -90% part efficiency
|-
| '''Carcinoma (extreme)''' || 100% severity ||
* Affected part is destroyed
|}

Treatment:
* Treated every {{ticks|240000}}
* The carcinoma will disappear if severity reaches 0.
* "Excise carcinoma" surgery; this needs 4 medicine of [[medicine|industrial quality]] or above, {{ticks|4500}} of work, and a doctor with a [[medical]] skill of 10 or above. The surgery has a 100% base chance to succeed. If it fails, there is a 25% chance that the patient [[Death|dies]]. Thus, as the maximum [[Doctoring#Success chance|success chance]] is capped at 98%, there is always at least a 0.5% chance of death per attempt.

A human pawn must be at least 22.4 years old to get carcinoma from aging, meaning it can first occur at their 23rd birthday. Carcinomas from other sources, including [[toxic buildup]] and [[nuclear stomach]]s{{RoyaltyIcon}}, can happen at any age. Installed nuclear stomachs create a carcinoma on the torso with an MTB of 120 days.

=== Dementia ===
Dementia is simply the functionality of the brain declining, and affects all cognitive functions.

It can only be healed with a [[healer mech serum]], [[luciferium]], [[unnatural healing]]{{AnomalyIcon}} or the [[chronophagy]] psychic ritual.{{AnomalyIcon}}

=== Artery blockage ===
A blockage in one of the critical arteries in the [[heart]]. Heart artery blockages randomly induce [[#Heart attack|heart attacks]]. Artery blockages can be treated by replacing the heart with a [[heart|natural]], [[prosthetic heart|prosthetic]] or [[bionic heart|bionic]] replacement, with a [[healer mech serum]], with [[luciferium]], or with the use of [[biosculpter pod]]'s bioregeneration cycle{{IdeologyIcon}}.

Artery blockages progress by a base of 0.0007 per day, multiplied by a random factor between 0.5 - 3.
This means that artery blockages can take anywhere from 7.9 to 47.6 in-game years from onset to become fatal on its own.

Artery blockages can be treated by replacing the heart.

== Acute ==
Some ailments arise as a result of an acute lack of food or exposure to extreme temperatures. These ailments can only be treated by addressing the underlying cause (e.g. providing food or moving to more comfortable temperatures).

=== Malnutrition ===
When a pawn's [[Eating|food]] meter reaches 0%, they will begin to suffer from [[malnutrition]], shown on the health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

Malnutrition severity without food will advance at an average of 17% per day. There is a variation for each pawn that will vary this by 20% in both directions, meaning a pawn may actually die of malnutrition between 4.9~7.4 days of first having symptoms. There is no stat indicating the specific rate that a pawn may die of malnutrition, but the modified rate is determined for each specific pawn in a given playthrough.

=== Blood loss ===
{{About|section=1|the effect of already lost blood|the mechanics that cause blood loss|Bleeding}}
A reduction in the normal blood volume. Minor blood loss has relatively mild effects, but as severity increases, the [[consciousness]] rapidly become debilitating. Extreme blood loss leads to [[death]]. Total blood loss is listed under whole body, with a tooltip showing the percent.

Blood loss can occur when a pawn has untreated [[Injury#Bleeding|bleeding injuries]], has had blood harvested for [[hemogen pack]]s,{{BiotechIcon}} or has been fed on by a [[Bloodfeeder]].{{BiotechIcon}} Blood loss from multiple sources stacks additively.

All pawns recover 33.3% of their blood per day, regardless of [[traits]], [[genes]], [[drugs]], or [[artificial body parts]]. All natural blood recovery is stopped when a pawn is [[bleeding]], even in small amounts. Pawns can also recover through a blood transfusion operation, using 1 [[hemogen pack]]{{BiotechIcon}} to recover 35%. The [[Biosculpter_pod#Medic|biosculpter pod's medic cycle]]{{IdeologyIcon}} will also cure all blood loss, though it should be noted that non-transhumanist pawns would recover completely from blood loss in the same time as the cycle takes to complete anyway. If there is no other reason to use the medic cycle, non-transhumanist pawns should just recover outside of the pod and remain productive for that time.

=== Heatstroke ===
Heat stroke occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) above their [[maximum comfortable temperature]], and recovery occurs in temperatures less than the maximum comfortable temperature.
Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.

Pawns additionally take periodic burn damage in temperatures more than 150°C (270°F) above their maximum comfortable temperature.
====Severity Increase====

The procedure for determining severity growth every 60-tick interval, '''SG60''' for short, is given by:
# Take the amount by which the ambient temperature exceeds the pawn's maximum safe temperature (which is the maximum comfortable temperature +10°C).
# Pass the amount through the curve shown below to obtain the effective temperature excess.
## Note that for amounts from 0 to 25 °C, this doesn't result in a change.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval (60 ticks, 1 second).
# If the growth is less than <code>0.000375</code>, set it to that number. This sets a minimum amount the severity increases by for temperatures in the range of 10 to 15.814°C above the maximum comfortable temperature.
:<code>'''SG60''' = max(0.000375, 0.0000645 × effective_temperature_curve(<i>ambient_temperature</i> - (<i>maximum_comfortable_temperature</i> + 10°C)))</code>
::<code><i>where </i>effective_temperature_curve()<i> is a post-processing curve with points</i>: (0, 0), (25, 25), (50, 40), (100, 60), (200, 80), (400, 100), (4000, 1000).</code>

====Severity Decrease====
If the ambient temperature is less than the maximum comfortable temperature, the amount the severity will decrease every 60-tick interval is given by:
:<code>Decrease in heatstroke severity every 60 ticks = max(0.0015, min(0.015, 0.027 × heatstroke_severity))</code>
This means that as long as the ambient temperature is less than the maximum comfortable temperature, heatstroke recovery is independent of temperature. Severity decreases at a constant rate of 1.5% when at 55.6% or above, slowing down until reaching its slowest (0.15%) at 5.6% and below. Full recovery from near-100% severity occurs after 151 real-time seconds, or 3.6 in-game hours.

=== Hypothermia ===
Hypothermia occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) below their [[minimum comfortable temperature]]. [[Insectoids]] don't experience hypothermia, but instead get [[hypothermic slowdown]].

Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike [[#Heatstroke|hyperthermia]], hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Hypothermic slowdown ===
{{quote|A special biological state used by some creatures to survive extreme cold. Instead of trying to stay warm, the creature's body chemistry adapts to prevent internal freezing despite very low temperature. Bodily functions are slowed and capacities are reduced, but the cold does no permanent damage. Some biologists call it a wakeful form of hibernation.}}

[[Insectoids]] avoid hypothermia and experience hypothermic slowdown instead with similar penalties but avoiding death at 100% and no [[frostbite]].

Slowdown value increases many times above 100% with apparently no upper limit. When defrosting insects this total value is used so defrost time is proportional to total time frozen.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:

=== Vacuum exposure ===
{{Odyssey|section=1}}
Vacuum exposure occurs when a pawn is subjected to [[Orbit|hard vacuum]] without adequate protection.

The rate of severity growth is directly proportional to the vacuum percentage of the pawn's current tile, and to the difference between 1 and a pawn's [[vacuum resistance]] stat. Vacuum will be 100% outside pressurized rooms; otherwise, it will vary depending on the presence of [[oxygen pump]]s, open connections to other rooms, and so on. The specific algorithm is:
# Start with a default of 2% per second.
# Multiply the amount by the tile's current vacuum percentage.
# Multiply the product by the difference between 1 and the pawn's vacuum resistance.
Expressed as a formula, the increase of severity every {{ticks|60}} is:
:<code>Increase in vacuum exposure severity = 0.02 * tile vacuum percentage * (1 - vacuum resistance)</code>

Vacuum exposure builds up extremely quickly in pawns without significant vacuum resistance. An unprotected pawn with no resistance will die in just {{ticks|3000}} of exposure to a complete vacuum, making even brief spacewalks a risky prospect.

Pawns recover quickly from vacuum exposure while inside a pressurized area; severity will simply fall at a flat 10% per second until the condition disappears entirely. Affected pawns that reach 100% vacuum resistance while still exposed (such as by equipping a [[vacsuit]]) will keep their current level of exposure until they return to a pressurized tile, but its severity will not increase any further.

== Pregnancy ==
{{See also|Animals#Mating{{!}}Mating|Animals#Breeding{{!}}Breeding|Reproduction{{!}}Human pregnancy}}
{{quote|This creature is gestating offspring. It will give birth if the pregnancy comes to term. If starved or injured, there may be a miscarriage.|Description}}

Tamed, non-[[human]], non-[[insectoid]], non-[[egg]]laying, female [[animals]] have a 50% chance to get pregnant from [[Animals#Mating|mating]]. While this is not an ailment in the traditional sense, it does have mechanical effects. For the first {{ticks|600}} this condition will be invisible, after which point a message will come up mentioning the pregnancy.

Humans can be pregnant only if the [[Biotech DLC]]{{BiotechIcon}} is enabled. They have a different list of symptoms. See [[Reproduction]] for details.

A pregnant animal suffering from [[malnutrition]] of 25% or higher or that is injured may miscarry. Miscarriages are noted by an in-game message.

Some animals will give birth to multiple young. The probability of this is determined by a curve, and is different for each animal.

The duration, and thus the severity gain per day, depends on the gestation time of the animal in question.

=== Sterilized ===
{{Stub|section=1|reason=Missing details, sources, mechanics etc. Are there any other causes in humans?}}
{{Quote|This creature's reproductive system has been permanently shut down.|Description}}
[[Animals]] can be sterilized by use of the "Sterilize" [[operation]] to prevent them from being able to reproduce, and the sterilized animal won't attempt to mate with others nor will others attempt to mate with it. [[Egg]] laying animals will stop laying eggs when sterilized. The animal acts as normal in all other ways, including [[milk]] production.

Sterilizing a pregnant animal will not terminate the pregnancy.

The sterilization operation requires [[Medical]] skill of 3 and {{ticks|500}} of work.

Humans with the "Sterilized" health trait can only be healed with a [[healer mech serum]]. Pawns can{{Check Tag|Will?|Is it all failures or just a chance?}} receive the sterilized ailment from a failed vasectomy or IUD insertion.{{BiotechIcon}} It is currently unknown if there are other sources.

== Drug damage ==
These ailments are caused by excess drug use.

=== Cirrhosis ===
A degenerative [[liver]] disease caused by excessive [[alcohol]] consumption.
An otherwise healthy pawn with cirrhosis will have an [[immunity gain speed]] of 70%, making them extremely vulnerable to disease.

{| class="wikitable"

Treatment:
* The easiest method of treatment is the [[Organ harvesting|transplantation]] of a new liver. Due to the extreme vulnerability to disease, even if your colony dislikes organ harvesting it may be worth it to replace the livers of valuable pawns as doctors will struggle to get high enough tend qualities on diseases to counterbalance the decreased immunity gain, often needing a very good hospital plus a very good doctor or [[glitterworld medicine]] to do so.
* Other than transplantation, only [[healer mech serum]] and [[unnatural healing]]{{AnomalyIcon}} can cure cirrhosis.

Alcohol [[tolerance]] above '''45%''' imposes a chance to get [[cirrhosis]] in the liver proportional to the tolerance held.

* Kidney chemical damage can be cured by replacing with a non-damaged [[kidney]] or with a [[detoxifier kidney]]{{BiotechIcon}}

==Trauma savant==
Injuries to the brain can cause increased motor function, but loss of social capabilities.
{| class="wikitable"

|-
| '''Trauma savant''' ||
* +50% [[Manipulation]]
* x0% [[Talking]] and [[Hearing]]

* Nullifies all opinions of other pawns
|}

The chance to receive trauma savant on any physical (non-chemical) [[injury]] to the brain is equal to the percentage of the brain damaged multiplied by 0.12. For an adult human, this represents 1.2% chance per point of damage. Animals can also become trauma savants.

A [[Ghoul|Ghoul]]{{AnomalyIcon}} or a humans with the [[Scarless]]{{BiotechIcon}} gene will not get brain scars from damage to their brain, but they still have a chance to become trauma savants. This makes it possible to voluntarily give the condition to a pawn by repeatedly damaging and healing their brain, although this can be time consuming and expensive. For an adult human, the brain will need to take on average 83 points of damage. Using other methods to heal the brain such as the [[Biosculpter pod#Bioregeneration|Bioregeneration cycle]] of the [[biosculpter pod]]{{IdeologyIcon}} is theoretically possible, but prohibitively expensive.

Currently, the most cost-effective known method to damage the brain is to purposefully fail the surgery to remove a [[Painstopper|painstopper]]. Painstoppers are the cheapest brain implant that can be removed. Attempting to remove it costs only one [[herbal medicine]] and failing will not destroy the implant. Performing the operation outside, on a [[Sleeping spot]] or an [[Ancient bed]],{{IdeologyIcon}} in the dark, with a low level surgeon with lowered Sight and Manipulation will maximize the chance for the operation to fail. If the operation accidentally succeeds, then the patient should be moved to a high quality hospital to reinsert the painstopper, as failure would destroy the implant and greatly increase the overall cost. It takes on average between 50 and 100 failed brain operations for a patient to become trauma savant.

Trauma savant negates the [[consciousness]] penalty from all brain damage, including scars that existed before the condition. On another hand, those brain scars will still lower the brain's health and can potentially still cause pain. Also, Trauma savant will not prevent loss of consciousness from other brain conditions like Dementia.

Trauma savant can be healed with a [[healer mech serum]] or the [[Unnatural healing]]{{AnomalyIcon}} ability (or possibly through other means as well). It can also be treated by killing the pawn, [[Skull|removing their skull]]{{IdeologyIcon}} then resurrecting thanks to a [[Resurrector mech serum]] or [[death refusal]]{{AnomalyIcon}}.

==Bliss lobotomy==
{{Anomaly|section = 1}}
{{Main|Bliss lobotomy}}
A whole-body condition that gives a constant +20 mood bonus but imposes a -50% global learning factor penalty. Makes pawn incapable of cooking, construction, plant work, mining, crafting and intellectual. Can generate on [[horax cult|cultist]] raiders or be deliberately induced via a brain surgery at the cost of 2 medicine and 30 [[bioferrite|bioferrites]].

== General ==
These ailments appear in gameplay, and usually wear off on their own (except death-causing ones).

=== Cryptosleep sickness ===
After-effects of using a cryptosleep pod. Cryptosleep suspends and replaces many bodily functions in order to prevent aging and death. Upon exiting cryptosleep, the body takes time to restart and rebalance its natural metabolic processes. While this is ongoing, the patient suffers from nausea, dizziness, and a sense of fuzziness in the mind.

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists in the "[[Crashlanded]]" scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

|}
Treatment:
* Wears off after {{ticks|10000}}

=== Food poisoning ===
Occurs after eating a contaminated meal or occasionally from raw food. The chance of contamination for cooked meals is primarily determined by the cook's [[food poison chance]] stat, with the [[Cleanliness|cleanliness of the room]] where it was prepared also being a potential factor.

[[Corpse]]s have a flat chance of 5% to give food poisoning. Other raw food has a flat chance in between 1% and 4% depending on the type of food — most raw food having a 2% chance. Cooked meals roll two separate probabilities to determine if the food is poisoned. The first checks the [[cleanliness]] of the kitchen used. See the accompanying graph for specifics. Note that cleanliness above -2 prevents this roll from producing poisoned meals. If the cooking station is outdoors, the default chance is 2%.

If the first roll fails to poison the meal, then a second roll is performed, this time based on the [[food poison chance]] of the pawn, controlled entirely by their [[Cooking|cooking skill]].
If the second roll indicates that the meal is poisonous, the probability of poisoning the pawn is 100% for that individual meal. However, when the poisonous meal is part of a stack with other meals, the probability is distributed among all the meals in the stack. This distribution reduces the chance of food poisoning from 100% to the ratio of total meals to poisonous meals within the stack. For instance, if a poisonous meal is placed on top of a stack containing three non-poisonous meals, the probability for each meal to poison the pawn becomes 25%. Consequently, even if the original meal was poisonous, there is a possibility that no pawns will experience food poisoning.

Because of the penalty to [[blood filtration]] and [[consciousness]], food poisoning in combination with other ailments such as an [[infection]] can be a cause for concern.

; Symptoms and progress:
Food poisoning lasts 24 hours with no after-effects. It has 3 stages: the first unpleasant 4 hours, followed by a crippling 16 hours, and finally an unpleasant 4 hours largely similar to the first stage, as described in the table below.

|}
; Treatment and Prevention
Food poisoning can only be minimized by manipulating the factors that cause it mentioned above. Prevention can only be guaranteed by exclusively consuming meals purchased from traders or by making [[Baby food]] or [[nutrient paste meal]]s as they will never cause food poisoning. Installing a [[sterilizing stomach|sterilizing]] {{RoyaltyIcon}}, [[nuclear stomach]] {{RoyaltyIcon}} or [[fleshmass stomach]] {{AnomalyIcon}}, or having the [[strong stomach]] gene{{BiotechIcon}} render pawns immune to contracting food poisoning. Note that [[bionic stomach]]s reduce the chance of getting food poisoning by 50% but cannot outright prevent it.

The notification for a colonist being poisoned will explain the cause of the poisoning. This can be very helpful if an unattended kitchen was allowed to cross into the very dirty -2 cleanliness danger zone, as a nearby cleaner can simply be ordered to clean the kitchen and avoid more unnecessary poisoning.

There is no practical treatment for food poisoning, you simply have to let it run its course. [[Healer mech serum]] will cure it (if there is nothing worse to cure), but this costly measure is rarely if ever worthwhile, as food poisoning only affects the pawn for the 24 hour cycle and then leaves them as healthy as they were before. [[Unnatural healing]]{{AnomalyIcon}} is the vastly more economical option, though it carries opportunity cost of the 6 day cooldown.

Because of the high chance of [[vomiting]] at any moment, putting the patient on a temporary diet of [[pemmican]] may be useful. Vomiting interrupts the process of eating, resetting it to the start, but a colonist can more quickly consume several pieces of pemmican between "attacks" that they can eat an entire [[meal]]. This allows the poisoned pawn to more easily avoid malnutrition without feeding them [[raw food]]s that could cause further poisoning.

=== Toxic buildup ===
{{Stub|section=1|reason=What is the effect of Toxic Environment Resistance vs Toxic Resistance, tox rain}}
Primarily occurs with exposure to [[toxic fallout]], [[pollution]],{{BiotechIcon}} and [[tox gas]].{{BiotechIcon}}. Prolonged exposure gradually increases the buildup severity.

Alternatively, some attacks cause instantaneous increases in toxic buildup severity, such as [[cobra]] and [[waste rat]] {{BiotechIcon}} bites, the [[venom talon]] {{RoyaltyIcon}}, or [[venom fangs]] {{RoyaltyIcon}}.

A colonist under a roof is protected from toxic fallout, and avoiding interaction with the other sources can prevent buildup from them. If they are exposed to the fallout, they will accumulate Toxic Buildup at a rate of 40% per day. Pollution will accumulate at the same rate, but cannot be mitigated through roofing. When walking through polluted terrain in [[caravan]]s, they will accumulate buildup at 20% per day in Moderately Polluted terrain (50%-75% polluted tiles) and 40% per day in Extremely Polluted terrain (above 75%). Buildup from both pollution as well as toxic fallout can stack, meaning a pawn standing in polluted terrain while a toxic fallout can gain 80%/day.

This buildup severity gained is proportional to the [[Toxic Resistance]] [[stat]] - thus, [[human]]s buildup at the full rate, [[animal]]s at half, and [[insects]] and [[mechanoids]] are immune.{{Check Tag|Body Size?|Buildup severities from Damage types are now inversely proportional to body size, are all sources scaled? Either way, add detail}} Buildup can also be reduced through a variety of of other means including items such as the [[gas mask]] {{BiotechIcon}}, [[detoxifier kidney]] {{BiotechIcon}}, and [[detoxifier lung]] {{BiotechIcon}}, as well as [[genes]]{{BiotechIcon}} such as [[Partial antitoxic lungs]]{{BiotechIcon}} and [[Total antitoxic lungs]],{{BiotechIcon}} or [[Tox resistance]]{{BiotechIcon}} and [[Tox immunity]].{{BiotechIcon}}

There is, effectively, a multiplier for each pawn on their toxic buildup accumulation from these indirect sources. This can vary between 15% faster buildup or 15% slower buildup than the average rate. There is no stat in the information panel to convey this variation, but it is static for a given pawn. This means that baseliner humans standing in pollution and a toxic fallout, with no Tox Resistance of any sort, can vary from either 68% to 92% buildup per day, rather than a constant 80%.

The buildup severity occurs in stages. The later stages cause permanent [[#Dementia|dementia]] which does not wear off even after toxic buildup subsides. When a pawn affected by toxic buildup [[Death|dies]], there is a chance that its corpse will instantly rot - this chance is equal to the severity.

Once a colonist returns to a safe area, such as a roofed area for toxic fallout, or otherwise stops taking severity increases, their buildup severity will gradually decrease. Once no longer exposed, severity reduces by 8% per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach high stages of toxic buildup are likely to develop further complications.

{{quote|"This person was in a growth vat which wasn't functioning properly due to lack of power or nutrition feedstock. This has left their body in a state of bio-starvation."|In-game description}}
A pawn in a [[growth vat]] with no power or nutrition, will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. These include:
* [[Pain]]: {{++|15%}}
* [[Hunger Rate Factor]] offset: {{++|50%}}
* [[Consciousness]]: {{--|25%}}

=== Vomiting ===
{{Stub|section=1|reason=what does it interrupt, what happens when different tasks are underway - e.g. eating cancels the eating task but doesn't waste the meal, explanation that vomiting is expressed as mtb etc}}
The body attempting to forcefully expunge toxins. Unfortunately for your pawns, this doesn't work in Rimworld.

Vomiting is caused by a wide variety of ailments{{Check Tag|List Needed?}}, some [[Psycasts]]{{RoyaltyIcon}}, or being hit with an EMP while having the [[Sterilizing stomach|Sterilizing]], [[Reprocessor stomach|Reprocessor]], or [[Nuclear stomach|Nuclear]] stomachs{{RoyaltyIcon}} installed.

A pawn that is vomiting will stop in place, face the side, and begin vomiting. Vomiting lasts a random duration from {{Ticks|300}} to {{Ticks|900}}, and every 150 interval ticks it reduces the pawn's food bar by 0.04 and generates 1 stack of [[vomit]] filth on the tile they're facing. Note that this interval tick occurs independently from the beginning of the vomiting duration, and as such the number of times it occurs may not be the simple division of the chose duration divided by 150. As such, between one fewer and one more interval may occur than the the division would indicate. A pawn lying in a bed will not stand up to vomit{{Check Tag|Details|Does this pause the resting bonus from lying down? Does it wake them up?}}.

Vomiting will interrupt most tasks, including eating, walking, aiming a weapon, or working at a station, but they will resume the task once they stop vomiting{{Check Tag|Mechanics|Do pawns who are actively vomiting still reserve the task they were working on?}}. For this reason, it is recommended that pawns who are afflicted with an ailment that causes frequent vomiting, such as [[food poisoning]], eat foods like [[pemmican]], as a pawn who vomits while in the middle of eating a normal meal will lose all progress towards consuming it (note that the meal is not wasted), but a pawn eating pemmican will still consume part of the stack. Similarly, they should also avoid long tasks that have their progress reset on being interrupted, such as cooking 4x [[lavish meal]]s.

=== Crumbling mind ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}

The gradual breakdown of the mind. While technically non-fatal, it applies mounting consciousness penalties, and its final stage renders a pawn incapable of nearly all work.

Crumbling mind is caused by two [[Anomaly]] events - The [[Corrupted obelisk]] and the [[Creepjoiner]]. It cannot affect pawns that existed before those events, only ones created by them. It can be detected before ailments show by a surgical inspection.

Creepjoiners with this condition will begin showing symptoms within 2-3.33 days. Duplicated pawns will begin showing them within 12-48 hours. Severity progresses by 33% per day. Progress can be paused through the use of a [[cryptosleep casket]].

Crumbling mind can be cured by a [[healer mech serum]] as well as the [[unnatural healing]] ability so long as it hasn't progressed to the final stage of '''Crumbled mind'''. Once it has, the condition is incurable, short of destroying the colonists brain then resurrecting them with either a [[resurrector mech serum]] or [[death refusal]]. However, consistently destroying the brain can be difficult. There are 5 main ways to archive it:
* With the [[Biotech DLC]], using a [[Subcore ripscanner]] on the colonist in question will kill it by destroying its brain.
* Also with the Biotech DLC, extracting the pawn's genes with a [[Gene extractor]] while the '''Genes Regrowing''' Hefiff remains active will kill it by brain destruction.
* With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will destroy its head reliably and safely.
* Fatal [[Luciferium]] withdraw kills by destroying the brain.
* Allow colonists or animals to eat sections of the corpse, risking consuming the entire body before the head is removed.

Furthermore, no matter how successful the head removal, the costs and downsides of the either the serum or refusal remain. If this strategy is used, remember not to euthanize them or they will be no longer of your faction after resurrection.

Counterintuitively, [[Ghoul|ghoul infusion]] will not cure crumbling mind and it will hinder ghoul's combat abilities.

=== Duplicate sickness ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}
Psychic interference between this person and their duplicate is causing slow mental deterioration. As long as multiple copies of this person are alive, the condition will keep getting worse. However, the condition will not be lethal.

Duplicate sickness is one of the potential outcomes from the duplication of a pawn by a [[corrupted obelisk]].

It cannot be treated,{{Check Tag|Verify}} but can be cured by one of three methods: [[healer mech serum]], the [[unnatural healing]] ability, or the death of one of the two pawns.

If one of the two connected pawns is killed, the other's duplication sickness severity immediately starts regressing at the rate of 50% per day, while the killed pawn's duplication sickness is instantly cured. The killed pawn can then be immediately resurrected with a [[resurrector mech serum]] or [[death refusal]] without stopping the regression of the other pawn's sickness. Similarly, if one of the linked pawns is turned into a [[ghoul]], killed, and revived with a [[ghoul resurrection serum]], the same mechanics apply.

== Surgical ==
These ailments happen with medical operations.

=== Anesthetic ===
Used in surgery to make sure that a pawn is unconscious. It can also be administered outside of operations using a medical bill, consuming medicine.

A pawn under anesthesia is unconscious for the first 6 hours, and the worst effects of anesthetic wear off after 12 hours, so arranging operations to be performed some time just before a pawn needs to sleep is recommended if you want them functioning the next work day.

Treatment:
* Wears off on its own between {{ticks|45000}} to {{ticks|75000}} even if severity has not reached 0%
** Surgery is unaffected even if it wears off before finished

==== Version history ====
Prior to 1.1 it lasted only {{ticks|15000}} and did not have any other stages afterwards.

== Resurrection ==
These may occur after a dose of [[resurrector mech serum]] is applied on a [[Death|dead]] pawn.

=== Resurrection sickness ===
After-effects of being resurrected by mechanite injection. Artificially-kickstarted body processes take time to rebalance themselves.

{| class="wikitable"
|-
! Ailment !! Symptoms
|-
| '''Resurrection sickness''' ||

|}

'''Treatment:'''
* Wears off anywhere from {{ticks|90000}} to {{ticks|150000}}

'''Probability:'''
* 100% chance of being applied

=== Blindness ===
Mechanites fail to properly repair the eyes, instead causing more damage to it, resulting in blindness.

Blindness from [[resurrector mech serum]] applies to both eyes, resulting in total blindness

{| class="wikitable"
|-
! Ailment !! Symptoms
|-
| '''Blindness''' ||

'''Treatment:'''
* Replace eyes with [[bionic eye]]s or [[archotech eye]]s

'''Probability:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

=== Resurrection psychosis ===
Chaotic thought patterns caused by the decoherence of resurrection mechanites. Resurrection psychosis progresses and eventually causes total psychosis and [[death]].

The severity of the psychosis increases by 0.01 per day, meaning that it will kill in 100 days after resurrection, or 90 days after this ailment becoming visible. Hopefully this gives you enough time to find a [[healer mech serum]] to heal the ailment, find another [[resurrector mech serum]] to attempt the resurrection again once the psychosis has run its course, or build a [[cryptosleep casket]] to give you time to find either serum. There are no other ways to cure the disease.

|}

'''Treatments:'''
* Healer mech serum
* Allowing the pawn to [[Death|die]] again, then resurrecting once more (rerolls the disease)

'''Probability of contracting:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

'''Prevention:'''
* Freeze corpses immediately after death. Corpses placed in a [[sarcophagus]] are still affected by the temperature of the room they are in, and can be removed later but are protected from butchering, hungry animals and assuming you build the sarcophagus from something [[Flammability|non-flammable]], [[fire]].

== Heart attack ==
Heart attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in humans), triggered by the [[Events#Birthday|birthday event]]. There must be 2 or more colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days):
* 0-60% of life expectancy: 99,999,999 - 99,999,999
* 60-80% of life expectancy: 99,999,999 - 2,500
* 80-100% of life expectancy: 2,500 - 300

Examples of intervals and chances:
* 70% of life expectancy (i.e. 56 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
* 90% of life expectancy (i.e. 72 in humans): 1,400 days (approx. 0.000714% per day)

=== Stages ===
{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms
|-
|'''Painful''' || 0% Severity ||
* [[Consciousness]] ×50%
* [[Pain]] +40%
|-
|'''Debilitating''' || 60% Severity ||
* [[Consciousness]] max. 10% (Unconsciousness)
* [[Pain]] +60%
|-
|'''Fatal''' || 100% Severity ||
* [[Death]]
|}

==== Progression ====
Heart attacks always start at 40% severity. Each interval the heart attack severity will randomly change by a value between {{---|40%}} to {{++|60%}}. This means that it is possible for a heart attack to recover on its own, but usually (~76% likelihood){{Check Tag|Detail needed|How is this calculated??}} an untreated heart attack progresses to fatal severity. The interval between changes is random, and varies between {{Ticks|500}} and {{Ticks|10000}}.

==== Treatment ====
Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by {{---|30%}}. Successfully reducing severity below 0% will completely treat the heart attack.

The chance a particular treatment can succeed is 65% multiplied by the [[tend quality]], for an effective maximum of 84.5% with [[glitterworld medicine]].

==== Prevention ====
Replacing a pawn's heart with either a [[prosthetic heart|prosthetic]] or [[bionic heart]] will completely prevent heart attacks. Note however that while the bionic heart improves the [[blood pumping]] capacity, the prosthetic heart decreases it, and thus all of the stats and capacities it affects.

== Version history ==
* [[Version/0.7.581|0.7.581]] Added with cataracts and bad back
* [[Version/0.8.657|0.8.657]] - Added hypothermia, frostbite, heatstroke, and burns from being in areas with extreme temperatures.

* [[Version/0.10.785|0.10.785]] - Starvation and blood loss are now staged and affect consciousness as they worsen.
* [[Version/0.12.906|0.12.906]] - All organisms including animals have life expectancies and will develop chronic conditions like frailty or cataracts in old age. Heart attacks added.
* [[Version/0.13.1135|0.13.1135]] - Carcinoma, asthma, and hearing loss added.
* [[Version/1.0.0|1.0.0]] - Minor starvation (below 25% severity) no longer causes miscarriages.
* [[Version/1.1.0|1.1.0]] - Pregnant animal is no longer viewed as sick because pregnancy affects its capacities. and thus now sells for the same as one with no health conditions.
* [[Version/1.3.3117|1.3.3117]] - Extreme blood loss now reduces consciousness by 40% in addition to setting the capacity's max to 10%. Prior to this, pawns could nonsensically [[Death|die]] by healing from extreme to severe bloodloss if their consciousness was below 40% from other symptoms - extreme would simply max it at 10% but healing to severe would reduce it by 40% to 0% and kill the pawn.
* [[Version/1.4.3523|1.4.3523]] - Sterilized animals no longer lay eggs.
* [[Version/1.6.4518|1.6.4518]] - Vacuum exposure implemented with [[Odyssey]].

'''Ailments''' are [[health]] conditions that cannot be treated completely using medicine alone.

"MTB" stands for "Mean Time Between", and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

Most permanent ailments are curable with body part replacements or usage of the [[healer mech serum]].

{{Heal Option Table}}

== Chronic ==
Ailments that come with age. Either non-fatal, or progresses extremely slowly towards fatality compared to infectious diseases.

=== Alzheimer's ===
{{stub|reason = "Forget memory" and "confused wandering" mechanics}}
A brain disease usually associated with aging. Alzheimer's disease causes progressive degradation in the ability to think and remember. Patients are known to forget close relatives and sometimes wander around in confusion.

Alzheimer's progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity from when it first appears.

'''Treatment:'''
* [[Luciferium]]: Luciferium removes one randomly selected condition that it can cure every 900,000 to 1,800,000 [[ticks]] (15 - 30 in-game days). Having fewer luciferium-curable conditions will increase the chance that Alzheimer's is chosen, so it can be worth attempting to address any conditions that can be other means. Even with this however, it can take a significant amount of time. Also note that luciferium is a permanent decision - once taken, further doses are necessary to avoid madness and death.
* [[Healer mech serum]]: A healer mech serum will instantaneously heal one condition of the pawn, including Alzheimer's. Which condition is chosen depends on a priority order, with Alzheimer's being a moderately high priority. See the serum's [[Healer mech serum#Summary|condition order]] for details.
* [[Resurrector mech serum]]: Because the resurrector mech serum will replace a destroyed head with a healthy one, it can be used to heal brain ailments, including Alzheimers. Consistently destroying the head can be difficult. With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will do this reliably and safely, but without it, the best way is allowing colonists or animals to eat sections of the corpse, at the risk of consuming the entire body and permanently losing the pawn. Furthermore, no matter how successful the head removal, there is always the risks normally associated with resurrection, including [[dementia]], [[blindness]], and [[resurrection psychosis]]. Note that pawns will initially be incapacitated due to resurrection sickness.
* [[Death refusal]]{{AnomalyIcon}}: Similar to the [[Resurrector mech serum]], a pawn imbued with death refusal can self-resurrect and replace a destroyed head with a healthy one. This comes with the drawback of the pawn losing experience in their skills that happens upon imbuing the death refusal. Pawns resurrected via this method will also have resurrection sickness and a negative [[Mood|moodlet]] upon being resurrected.
* [[Chronophagy]]{{AnomalyIcon}}: As pawns younger than 34 cannot get Alzheimer's, reversing age to younger than that in a Chronophagy ritual will remove it.
* [[Unnatural healing]]{{AnomalyIcon}}: a Creepjoiner with unnatural healing replicates the effect of a healer mech serum and so can be similarly used to cure Alzheimers at the minor risk of replacing an arm with a flesh tentacle for the cured pawn

=== Asthma ===
A chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. Unlike other chronic diseases, asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line.

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity (50%).

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% beginning to regress the stages of asthma (the higher, the better).

{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms
|-
| '''Asthma (minor)''' || ≥ 0% severity || -10% part efficiency
|-
| '''Asthma (major)''' || ≥ 30% severity || -30% part efficiency
|-
| '''Asthma (major)''' || ≥ 45% severity || -50% part efficiency
|}

Treatment:
* The severity of asthma can be reduced with treatment, which can be given every 420,000 ticks (around 7 days). One treatment applies to both lungs.
* Asthma can be cured by replacing each affected lung with a [[Lung#Acquisition|healthy replacement]].

A human pawn can first get asthma at any age.

|}

Asthma can also affect animals, domestic, tamed and wild. Domestic and tamed will notify you that they "need treatment", although there apparently is no downside for ignoring that request except slowing them down which may be bad for [[Animals#Training|trained]] or [[pack animal]]s. Similarly, asthmatic wild animals on the map can roam and eat indefinitely without treatment. In fact, wild animals with asthma are easier and slightly safer to hunt, because asthma will reduce their [[move speed]] to 81%, and their [[manipulation]] to only 90%, which makes any counter-attack less effective.

=== Bad back ===
Degradation in the spinal column and surrounding musculature. This makes it hard to move and bend smoothly.

Cataracts can be cured through the following methods:
* Replacing the affected eyes with a [[bionic eye|bionic]] or [[archotech eye|archotech]] eye.
* Use of a [[healer mech serum]] which will heal cataracts in both eyes at once
* Via [[luciferium]] use. Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.
* Through the use of the [[biosculpter pod]]'s bioregeneration cycle.{{IdeologyIcon}}
* Via the [[Scarless]] gene.{{BiotechIcon}} Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.

=== Carcinoma ===
{{Stub|section=1|reason=How do the stages progress/occur and what chances and factors affects them?}}
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumors, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed by a skilled doctor or, in some cases, the affected body part can be removed, either by amputation, transplantation of a healthy body part, or replacement by an [[artificial body part]]. Ordinary treatment will prolong the development of a carcinoma or speed up remission, and can be done by doctors of any skill, though better treatment quality is more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.
* When growing, it progresses by 0.003 per day, multiplied by a random factor of 0.45 - 1.65.
* When stable, it neither grows nor regresses on its own.
* When in remission, it regresses by 0.002 per day, multiplied by a random factor of 0.7 - 1.5.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will:
* grow more slowly when in growing stage
:* some slow-growing carcinomas (something less than half) may stop or actually regress (very slowly) during their "growing" stage with good treatment
* slowly regress when stable
* regress quickly when in remission

* Acute pain (+60%)
* -90% part efficiency
|-
| '''Carcinoma (extreme)''' || 100% severity ||
* Affected part is destroyed
|}

Treatment:
* Treated every {{ticks|240000}}
* The carcinoma will disappear if severity reaches 0.
* "Excise carcinoma" surgery; this needs 4 medicine of [[medicine|industrial quality]] or above, {{ticks|4500}} of work, and a doctor with a [[medical]] skill of 10 or above. The surgery has a 100% base chance to succeed. If it fails, there is a 25% chance that the patient [[Death|dies]]. Thus, as the maximum [[Doctoring#Success chance|success chance]] is capped at 98%, there is always at least a 0.5% chance of death per attempt.

A human pawn must be at least 22.4 years old to get carcinoma from aging, meaning it can first occur at their 23rd birthday. Carcinomas from other sources, including [[toxic buildup]] and [[nuclear stomach]]s{{RoyaltyIcon}}, can happen at any age. Installed nuclear stomachs create a carcinoma on the torso with an MTB of 120 days.

=== Dementia ===
Dementia is simply the functionality of the brain declining, and affects all cognitive functions.

=== Artery blockage ===
A blockage in one of the critical arteries in the [[heart]]. Heart artery blockages randomly induce [[#Heart attack|heart attacks]]. Artery blockages can be treated by replacing the heart with a [[heart|natural]], [[prosthetic heart|prosthetic]] or [[bionic heart|bionic]] replacement, with a [[healer mech serum]], with [[luciferium]], or with the use of [[biosculpter pod]]'s bioregeneration cycle{{IdeologyIcon}}.

Artery blockages progress by a base of 0.0007 per day, multiplied by a random factor between 0.5 - 3.
This means that artery blockages can take anywhere from 7.9 to 47.6 in-game years from onset to become fatal on its own.

Artery blockages can be treated by replacing the heart.

== Acute ==
Some ailments arise as a result of an acute lack of food or exposure to extreme temperatures. These ailments can only be treated by addressing the underlying cause (e.g. providing food or moving to more comfortable temperatures).

=== Malnutrition ===
When a pawn's [[Eating|food]] meter reaches 0%, they will begin to suffer from [[malnutrition]], shown on the health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

Malnutrition severity without food will advance at an average of 17% per day. There is a variation for each pawn that will vary this by 20% in both directions, meaning a pawn may actually die of malnutrition between 4.9~7.4 days of first having symptoms. There is no stat indicating the specific rate that a pawn may die of malnutrition, but the modified rate is determined for each specific pawn in a given playthrough.

=== Blood loss ===
{{About|section=1|the effect of already lost blood|the mechanics that cause blood loss|Bleeding}}
A reduction in the normal blood volume. Minor blood loss has relatively mild effects, but as severity increases, the [[consciousness]] rapidly become debilitating. Extreme blood loss leads to [[death]]. Total blood loss is listed under whole body, with a tooltip showing the percent.

Blood loss can occur when a pawn has untreated [[Injury#Bleeding|bleeding injuries]], has had blood harvested for [[hemogen pack]]s,{{BiotechIcon}} or has been fed on by a [[Bloodfeeder]].{{BiotechIcon}} Blood loss from multiple sources stacks additively.

All pawns recover 33.3% of their blood per day, regardless of [[traits]], [[genes]], [[drugs]], or [[artificial body parts]]. All natural blood recovery is stopped when a pawn is [[bleeding]], even in small amounts. Pawns can also recover through a blood transfusion operation, using 1 [[hemogen pack]]{{BiotechIcon}} to recover 35%. The [[Biosculpter_pod#Medic|biosculpter pod's medic cycle]]{{IdeologyIcon}} will also cure all blood loss, though it should be noted that non-transhumanist pawns would recover completely from blood loss in the same time as the cycle takes to complete anyway. If there is no other reason to use the medic cycle, non-transhumanist pawns should just recover outside of the pod and remain productive for that time.

=== Heatstroke ===
Heat stroke occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) above their [[maximum comfortable temperature]], and recovery occurs in temperatures less than the maximum comfortable temperature.
Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.

Pawns additionally take periodic burn damage in temperatures more than 150°C (270°F) above their maximum comfortable temperature.
====Severity Increase====

The procedure for determining severity growth every 60-tick interval is given by:
# Take the amount by which the ambient temperature exceeds the pawn's maximum safe temperature (which is the maximum comfortable temperature +10°C).
# Pass the amount through the curve shown below to obtain the effective temperature excess. Note that for amounts from 0 to 25 °C, this doesn't result in a change.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval (60 ticks, 1 second).
# If the growth is less than <code>0.000375</code>, set it to that number. This sets a minimum amount the severity increases by for temperatures in the range of 10 to 15.814°C above the maximum comfortable temperature.
:<code>Increase in heatstroke severity every 60 ticks = max(0.000375, 0.0000645×effective_temperature_curve(<i>ambient_temperature</i> - (<i>maximum_comfortable_temperature</i> + 10°C)))</code>
::<code><i>where </i>effective_temperature_curve()<i> is a post-processing curve with points</i>: (0, 0), (25, 25), (50, 40), (100, 60), (200, 80), (400, 100), (4000, 1000).</code>

====Severity Decrease====
If the ambient temperature is less than the maximum comfortable temperature, the amount the severity will decrease every 60-tick interval is given by:
:<code>Decrease in heatstroke severity every 60 ticks = max(0.0015, min(0.015, 0.027×heatstroke_severity))</code>
This means that as long as the ambient temperature is less than the maximum comfortable temperature, heatstroke recovery is independent of temperature, but severity decreases at its fastest when it is above 50%, and at its slowest below 5.6%. Full recovery from near-100% severity occurs after 151 real-time seconds, or 3.6 in-game hours.

=== Hypothermia ===
Hypothermia occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) below their [[minimum comfortable temperature]]. [[Insectoids]] don't experience hypothermia, but instead get [[hypothermic slowdown]].

Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike [[#Heatstroke|hyperthermia]], hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Hypothermic slowdown ===
{{quote|A special biological state used by some creatures to survive extreme cold. Instead of trying to stay warm, the creature's body chemistry adapts to prevent internal freezing despite very low temperature. Bodily functions are slowed and capacities are reduced, but the cold does no permanent damage. Some biologists call it a wakeful form of hibernation.}}

[[Insectoids]] avoid hypothermia and experience hypothermic slowdown instead with similar penalties but avoiding death at 100% and no [[frostbite]].

Slowdown value increases many times above 100% with apparently no upper limit. When defrosting insects this total value is used so defrost time is proportional to total time frozen.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Vacuum exposure ===
{{Odyssey|section=1}}
Vacuum exposure occurs when a pawn is subjected to [[Orbit|hard vacuum]] without adequate protection.

The rate of severity growth is directly proportional to the vacuum percentage of the pawn's current tile, and to the difference between 1 and a pawn's [[vacuum resistance]] stat. Vacuum will be 100% outside pressurized rooms; otherwise, it will vary depending on the presence of [[oxygen pump]]s, open connections to other rooms, and so on. The specific algorithm is:
# Start with a default of 2% per second.
# Multiply the amount by the tile's current vacuum percentage.
# Multiply the product by the difference between 1 and the pawn's vacuum resistance.
Expressed as a formula, the increase of severity every {{ticks|60}} is:
:<code>Increase in vacuum exposure severity = 0.02 * tile vacuum percentage * (1 - vacuum resistance)</code>

Vacuum exposure builds up extremely quickly in pawns without significant vacuum resistance. An unprotected pawn with no resistance will die in just {{ticks|3000}} of exposure to a complete vacuum, making even brief spacewalks a risky prospect.

Pawns recover quickly from vacuum exposure while inside a pressurized area; severity will simply fall at a flat 10% per second until the condition disappears entirely. Affected pawns that reach 100% vacuum resistance while still exposed (such as by equipping a [[vacsuit]]) will keep their current level of exposure until they return to a pressurized tile, but its severity will not increase any further.

== Pregnancy ==
{{See also|Animals#Mating{{!}}Mating|Animals#Breeding{{!}}Breeding|Reproduction{{!}}Human pregnancy}}
{{quote|This creature is gestating offspring. It will give birth if the pregnancy comes to term. If starved or injured, there may be a miscarriage.|Description}}

Tamed, non-[[human]], non-[[insectoid]], non-[[egg]]laying, female [[animals]] have a 50% chance to get pregnant from [[Animals#Mating|mating]]. While this is not an ailment in the traditional sense, it does have mechanical effects. For the first {{ticks|600}} this condition will be invisible, after which point a message will come up mentioning the pregnancy.

Humans can be pregnant only if the [[Biotech DLC]]{{BiotechIcon}} is enabled. They have a different list of symptoms. See [[Reproduction]] for details.

A pregnant animal suffering from [[malnutrition]] of 25% or higher or that is injured may miscarry. Miscarriages are noted by an in-game message.

Some animals will give birth to multiple young. The probability of this is determined by a curve, and is different for each animal.

The duration, and thus the severity gain per day, depends on the gestation time of the animal in question.

=== Sterilized ===
{{Stub|section=1|reason=Missing details, sources, mechanics etc. Are there any other causes in humans?}}
{{Quote|This creature's reproductive system has been permanently shut down.|Description}}
[[Animals]] can be sterilized by use of the "Sterilize" [[operation]] to prevent them from being able to reproduce, and the sterilized animal won't attempt to mate with others nor will others attempt to mate with it. [[Egg]] laying animals will stop laying eggs when sterilized. The animal acts as normal in all other ways, including [[milk]] production.

Sterilizing a pregnant animal will not terminate the pregnancy.

The sterilization operation requires [[Medical]] skill of 3 and {{ticks|500}} of work.

Humans with the "Sterilized" health trait can only be healed with a [[healer mech serum]]. Pawns can{{Check Tag|Will?|Is it all failures or just a chance?}} receive the sterilized ailment from a failed vasectomy or IUD insertion.{{BiotechIcon}} It is currently unknown if there are other sources.

== Drug damage ==
These ailments are caused by excess drug use.

=== Cirrhosis ===
A degenerative [[liver]] disease caused by excessive [[alcohol]] consumption.
An otherwise healthy pawn with cirrhosis will have an [[immunity gain speed]] of 70%, making them extremely vulnerable to disease.

Treatment:
* The easiest method of treatment is the [[Organ harvesting|transplantation]] of a new liver. Due to the extreme vulnerability to disease, even if your colony dislikes organ harvesting it may be worth it to replace the livers of valuable pawns as doctors will struggle to get high enough tend qualities on diseases to counterbalance the decreased immunity gain, often needing a very good hospital plus a very good doctor or [[glitterworld medicine]] to do so.
* Other than transplantation, only [[healer mech serum]] and [[unnatural healing]]{{AnomalyIcon}} can cure cirrhosis.

Alcohol [[tolerance]] above '''45%''' imposes a chance to get [[cirrhosis]] in the liver proportional to the tolerance held.

Treatment:
* Kidney chemical damage can be cured by replacing with a non-damaged [[kidney]] or with a [[detoxifier kidney]]{{BiotechIcon}}

|}

The chance to receive trauma savant on any physical (non-chemical) [[injury]] to the brain is equal to the percentage of the brain damaged multiplied by 0.12. For an adult human, this represents 1.2% chance per point of damage. Animals can also become trauma savants.

A [[Ghoul|Ghoul]]{{AnomalyIcon}} or a humans with the [[Scarless]]{{BiotechIcon}} gene will not get brain scars from damage to their brain, but they still have a chance to become trauma savants. This makes it possible to voluntarily give the condition to a pawn by repeatedly damaging and healing their brain, although this can be time consuming and expensive. For an adult human, the brain will need to take on average 83 points of damage. Using other methods to heal the brain such as the [[Biosculpter pod#Bioregeneration|Bioregeneration cycle]] of the [[biosculpter pod]]{{IdeologyIcon}} is theoretically possible, but prohibitively expensive.

Currently, the most cost-effective known method to damage the brain is to purposefully fail the surgery to remove a [[Painstopper|painstopper]]. Painstoppers are the cheapest brain implant that can be removed. Attempting to remove it costs only one [[herbal medicine]] and failing will not destroy the implant. Performing the operation outside, on a [[Sleeping spot]] or an [[Ancient bed]],{{IdeologyIcon}} in the dark, with a low level surgeon with lowered Sight and Manipulation will maximize the chance for the operation to fail. If the operation accidentally succeeds, then the patient should be moved to a high quality hospital to reinsert the painstopper, as failure would destroy the implant and greatly increase the overall cost. It takes on average between 50 and 100 failed brain operations for a patient to become trauma savant.

Trauma savant negates the [[consciousness]] penalty from all brain damage, including scars that existed before the condition. On another hand, those brain scars will still lower the brain's health and can potentially still cause pain. Also, Trauma savant will not prevent loss of consciousness from other brain conditions like Dementia.

Trauma savant can be healed with a [[healer mech serum]] or the [[Unnatural healing]]{{AnomalyIcon}} ability (or possibly through other means as well). It can also be treated by killing the pawn, [[Skull|removing their skull]]{{IdeologyIcon}} then resurrecting thanks to a [[Resurrector mech serum]] or [[death refusal]]{{AnomalyIcon}}.

==Bliss lobotomy==
{{Anomaly|section = 1}}
{{Main|Bliss lobotomy}}
A whole-body condition that gives a constant +20 mood bonus but imposes a -50% global learning factor penalty. Makes pawn incapable of cooking, construction, plant work, mining, crafting and intellectual. Can generate on [[horax cult|cultist]] raiders or be deliberately induced via a brain surgery at the cost of 2 medicine and 30 [[bioferrite|bioferrites]].

== General ==
These ailments appear in gameplay, and usually wear off on their own (except death-causing ones).

=== Cryptosleep sickness ===
After-effects of using a cryptosleep pod. Cryptosleep suspends and replaces many bodily functions in order to prevent aging and death. Upon exiting cryptosleep, the body takes time to restart and rebalance its natural metabolic processes. While this is ongoing, the patient suffers from nausea, dizziness, and a sense of fuzziness in the mind.

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists in the "[[Crashlanded]]" scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

|}
Treatment:

=== Food poisoning ===
Occurs after eating a contaminated meal or occasionally from raw food. The chance of contamination for cooked meals is primarily determined by the cook's [[food poison chance]] stat, with the [[Cleanliness|cleanliness of the room]] where it was prepared also being a potential factor.

[[Corpse]]s have a flat chance of 5% to give food poisoning. Other raw food has a flat chance in between 1% and 4% depending on the type of food — most raw food having a 2% chance. Cooked meals roll two separate probabilities to determine if the food is poisoned. The first checks the [[cleanliness]] of the kitchen used. See the accompanying graph for specifics. Note that cleanliness above -2 prevents this roll from producing poisoned meals. If the cooking station is outdoors, the default chance is 2%.

If the first roll fails to poison the meal, then a second roll is performed, this time based on the [[food poison chance]] of the pawn, controlled entirely by their [[Cooking|cooking skill]].
If the second roll indicates that the meal is poisonous, the probability of poisoning the pawn is 100% for that individual meal. However, when the poisonous meal is part of a stack with other meals, the probability is distributed among all the meals in the stack. This distribution reduces the chance of food poisoning from 100% to the ratio of total meals to poisonous meals within the stack. For instance, if a poisonous meal is placed on top of a stack containing three non-poisonous meals, the probability for each meal to poison the pawn becomes 25%. Consequently, even if the original meal was poisonous, there is a possibility that no pawns will experience food poisoning.

Because of the penalty to [[blood filtration]] and [[consciousness]], food poisoning in combination with other ailments such as an [[infection]] can be a cause for concern.

|}
; Treatment and Prevention
Food poisoning can only be minimized by manipulating the factors that cause it mentioned above. Prevention can only be guaranteed by exclusively consuming meals purchased from traders or by making [[Baby food]] or [[nutrient paste meal]]s as they will never cause food poisoning. Installing a [[sterilizing stomach|sterilizing]] {{RoyaltyIcon}}, [[nuclear stomach]] {{RoyaltyIcon}} or [[fleshmass stomach]] {{AnomalyIcon}}, or having the [[strong stomach]] gene{{BiotechIcon}} render pawns immune to contracting food poisoning. Note that [[bionic stomach]]s reduce the chance of getting food poisoning by 50% but cannot outright prevent it.

The notification for a colonist being poisoned will explain the cause of the poisoning. This can be very helpful if an unattended kitchen was allowed to cross into the very dirty -2 cleanliness danger zone, as a nearby cleaner can simply be ordered to clean the kitchen and avoid more unnecessary poisoning.

There is no practical treatment for food poisoning, you simply have to let it run its course. [[Healer mech serum]] will cure it (if there is nothing worse to cure), but this costly measure is rarely if ever worthwhile, as food poisoning only affects the pawn for the 24 hour cycle and then leaves them as healthy as they were before. [[Unnatural healing]]{{AnomalyIcon}} is the vastly more economical option, though it carries opportunity cost of the 6 day cooldown.

Because of the high chance of [[vomiting]] at any moment, putting the patient on a temporary diet of [[pemmican]] may be useful. Vomiting interrupts the process of eating, resetting it to the start, but a colonist can more quickly consume several pieces of pemmican between "attacks" that they can eat an entire [[meal]]. This allows the poisoned pawn to more easily avoid malnutrition without feeding them [[raw food]]s that could cause further poisoning.

=== Toxic buildup ===
{{Stub|section=1|reason=What is the effect of Toxic Environment Resistance vs Toxic Resistance, tox rain}}
Primarily occurs with exposure to [[toxic fallout]], [[pollution]],{{BiotechIcon}} and [[tox gas]].{{BiotechIcon}}. Prolonged exposure gradually increases the buildup severity.

Alternatively, some attacks cause instantaneous increases in toxic buildup severity, such as [[cobra]] and [[waste rat]] {{BiotechIcon}} bites, the [[venom talon]] {{RoyaltyIcon}}, or [[venom fangs]] {{RoyaltyIcon}}.

A colonist under a roof is protected from toxic fallout, and avoiding interaction with the other sources can prevent buildup from them. If they are exposed to the fallout, they will accumulate Toxic Buildup at a rate of 40% per day. Pollution will accumulate at the same rate, but cannot be mitigated through roofing. When walking through polluted terrain in [[caravan]]s, they will accumulate buildup at 20% per day in Moderately Polluted terrain (50%-75% polluted tiles) and 40% per day in Extremely Polluted terrain (above 75%). Buildup from both pollution as well as toxic fallout can stack, meaning a pawn standing in polluted terrain while a toxic fallout can gain 80%/day.

This buildup severity gained is proportional to the [[Toxic Resistance]] [[stat]] - thus, [[human]]s buildup at the full rate, [[animal]]s at half, and [[insects]] and [[mechanoids]] are immune.{{Check Tag|Body Size?|Buildup severities from Damage types are now inversely proportional to body size, are all sources scaled? Either way, add detail}} Buildup can also be reduced through a variety of of other means including items such as the [[gas mask]] {{BiotechIcon}}, [[detoxifier kidney]] {{BiotechIcon}}, and [[detoxifier lung]] {{BiotechIcon}}, as well as [[genes]]{{BiotechIcon}} such as [[Partial antitoxic lungs]]{{BiotechIcon}} and [[Total antitoxic lungs]],{{BiotechIcon}} or [[Tox resistance]]{{BiotechIcon}} and [[Tox immunity]].{{BiotechIcon}}

There is, effectively, a multiplier for each pawn on their toxic buildup accumulation from these indirect sources. This can vary between 15% faster buildup or 15% slower buildup than the average rate. There is no stat in the information panel to convey this variation, but it is static for a given pawn. This means that baseliner humans standing in pollution and a toxic fallout, with no Tox Resistance of any sort, can vary from either 68% to 92% buildup per day, rather than a constant 80%.

The buildup severity occurs in stages. The later stages cause permanent [[#Dementia|dementia]] which does not wear off even after toxic buildup subsides. When a pawn affected by toxic buildup [[Death|dies]], there is a chance that its corpse will instantly rot - this chance is equal to the severity.

Once a colonist returns to a safe area, such as a roofed area for toxic fallout, or otherwise stops taking severity increases, their buildup severity will gradually decrease. Once no longer exposed, severity reduces by 8% per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach high stages of toxic buildup are likely to develop further complications.

=== Brain shock ===
{{quote|"After-effects of an electrical shock to the brain. This is generally cause by feedback from brain implants hit by EMP pulses." - '''In-game description'''}}
Occurs when an [[EMP]] effect hits a pawn with the following brain implants:

* [[Neurocalculator]] {{RoyaltyIcon}}
* [[Circadian assistant]] {{RoyaltyIcon}}
* [[Circadian half-cycler]] {{RoyaltyIcon}}
* [[Pilot assistant]] {{OdysseyIcon}}

{{Biotech|section=1}}
{{quote|"This person was in a growth vat which wasn't functioning properly due to lack of power or nutrition feedstock. This has left their body in a state of bio-starvation."|In-game description}}
A pawn in a [[growth vat]] with no power or nutrition, will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. These include:
* [[Pain]]: {{++|15%}}
* [[Hunger Rate Factor]] offset: {{++|50%}}
* [[Consciousness]]: {{--|25%}}

=== Vomiting ===
{{Stub|section=1|reason=what does it interrupt, what happens when different tasks are underway - e.g. eating cancels the eating task but doesn't waste the meal, explanation that vomiting is expressed as mtb etc}}
The body attempting to forcefully expunge toxins. Unfortunately for your pawns, this doesn't work in Rimworld.

Vomiting is caused by a wide variety of ailments{{Check Tag|List Needed?}}, some [[Psycasts]]{{RoyaltyIcon}}, or being hit with an EMP while having the [[Sterilizing stomach|Sterilizing]], [[Reprocessor stomach|Reprocessor]], or [[Nuclear stomach|Nuclear]] stomachs{{RoyaltyIcon}} installed.

A pawn that is vomiting will stop in place, face the side, and begin vomiting. Vomiting lasts a random duration from {{Ticks|300}} to {{Ticks|900}}, and every 150 interval ticks it reduces the pawn's food bar by 0.04 and generates 1 stack of [[vomit]] filth on the tile they're facing. Note that this interval tick occurs independently from the beginning of the vomiting duration, and as such the number of times it occurs may not be the simple division of the chose duration divided by 150. As such, between one fewer and one more interval may occur than the the division would indicate. A pawn lying in a bed will not stand up to vomit{{Check Tag|Details|Does this pause the resting bonus from lying down? Does it wake them up?}}.

Vomiting will interrupt most tasks, including eating, walking, aiming a weapon, or working at a station, but they will resume the task once they stop vomiting{{Check Tag|Mechanics|Do pawns who are actively vomiting still reserve the task they were working on?}}. For this reason, it is recommended that pawns who are afflicted with an ailment that causes frequent vomiting, such as [[food poisoning]], eat foods like [[pemmican]], as a pawn who vomits while in the middle of eating a normal meal will lose all progress towards consuming it (note that the meal is not wasted), but a pawn eating pemmican will still consume part of the stack. Similarly, they should also avoid long tasks that have their progress reset on being interrupted, such as cooking 4x [[lavish meal]]s.

=== Crumbling mind ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}

The gradual breakdown of the mind. While technically non-fatal, it applies mounting consciousness penalties, and its final stage renders a pawn incapable of nearly all work.

Crumbling mind is caused by two [[Anomaly]] events - The [[Corrupted obelisk]] and the [[Creepjoiner]]. It cannot affect pawns that existed before those events, only ones created by them. It can be detected before ailments show by a surgical inspection.

Creepjoiners with this condition will begin showing symptoms within 2-3.33 days. Duplicated pawns will begin showing them within 12-48 hours. Severity progresses by 33% per day. Progress can be paused through the use of a [[cryptosleep casket]].

Crumbling mind can be cured by a [[healer mech serum]] as well as the [[unnatural healing]] ability so long as it hasn't progressed to the final stage of '''Crumbled mind'''. Once it has, the condition is incurable, short of destroying the colonists brain then resurrecting them with either a [[resurrector mech serum]] or [[death refusal]]. However, consistently destroying the brain can be difficult. There are 5 main ways to archive it:
* With the [[Biotech DLC]], using a [[Subcore ripscanner]] on the colonist in question will kill it by destroying its brain.
* Also with the Biotech DLC, extracting the pawn's genes with a [[Gene extractor]] while the '''Genes Regrowing''' Hefiff remains active will kill it by brain destruction.
* With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will destroy its head reliably and safely.
* Fatal [[Luciferium]] withdraw kills by destroying the brain.
* Allow colonists or animals to eat sections of the corpse, risking consuming the entire body before the head is removed.

Furthermore, no matter how successful the head removal, the costs and downsides of the either the serum or refusal remain. If this strategy is used, remember not to euthanize them or they will be no longer of your faction after resurrection.

Counterintuitively, [[Ghoul|ghoul infusion]] will not cure crumbling mind and it will hinder ghoul's combat abilities.

=== Duplicate sickness ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}
Psychic interference between this person and their duplicate is causing slow mental deterioration. As long as multiple copies of this person are alive, the condition will keep getting worse. However, the condition will not be lethal.

Duplicate sickness is one of the potential outcomes from the duplication of a pawn by a [[corrupted obelisk]]. It affects both the original pawn and the duplicate{{Check Tag|Wb other duplicates?|Test both a previous duplicate (i.e. use obelisk gizmo, wait cooldown use again) and mass cloning (i.e. when 30 pawns spawn when it reaches max activity}} and is initially hidden. Severity increases by 10% per day that both pawns are alive{{Check Tag|Wb in crypto?|Does severity increase if the pawn is in cryptosleep? If no, does it pause on both or just the one in crypto? If no, wb if both are in crypto?}} and gradually reduces the consciousness of both pawns and makes them more likely to have [[mental breaks]], before eventually rendering both comatose.

It cannot be treated,{{Check Tag|Verify}} but can be cured by one of three methods: [[healer mech serum]], the [[unnatural healing]] ability, or the death of one of the two pawns.

If one of the two connected pawns is killed, the other's duplication sickness severity immediately starts regressing at the rate of 50% per day, while the killed pawn's duplication sickness is instantly cured. The killed pawn can then be immediately resurrected with a [[resurrector mech serum]] or [[death refusal]] without stopping the regression of the other pawn's sickness. Similarly, if one of the linked pawns is turned into a [[ghoul]], killed, and revived with a [[ghoul resurrection serum]], the same mechanics apply.

== Surgical ==
These ailments happen with medical operations.

=== Anesthetic ===
Used in surgery to make sure that a pawn is unconscious. It can also be administered outside of operations using a medical bill, consuming medicine.

A pawn under anesthesia is unconscious for the first 6 hours, and the worst effects of anesthetic wear off after 12 hours, so arranging operations to be performed some time just before a pawn needs to sleep is recommended if you want them functioning the next work day.

Treatment:
* Wears off on its own between {{ticks|45000}} to {{ticks|75000}} even if severity has not reached 0%
** Surgery is unaffected even if it wears off before finished

==== Version history ====
Prior to 1.1 it lasted only {{ticks|15000}} and did not have any other stages afterwards.

== Resurrection ==
These may occur after a dose of [[resurrector mech serum]] is applied on a [[Death|dead]] pawn.

=== Resurrection sickness ===
After-effects of being resurrected by mechanite injection. Artificially-kickstarted body processes take time to rebalance themselves.

{| class="wikitable"

'''Probability:'''
* 100% chance of being applied

=== Blindness ===
Mechanites fail to properly repair the eyes, instead causing more damage to it, resulting in blindness.

Blindness from [[resurrector mech serum]] applies to both eyes, resulting in total blindness

{| class="wikitable"

* Replace eyes with [[bionic eye]]s or [[archotech eye]]s

'''Probability:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

=== Resurrection psychosis ===
Chaotic thought patterns caused by the decoherence of resurrection mechanites. Resurrection psychosis progresses and eventually causes total psychosis and [[death]].

The severity of the psychosis increases by 0.01 per day, meaning that it will kill in 100 days after resurrection, or 90 days after this ailment becoming visible. Hopefully this gives you enough time to find a [[healer mech serum]] to heal the ailment, find another [[resurrector mech serum]] to attempt the resurrection again once the psychosis has run its course, or build a [[cryptosleep casket]] to give you time to find either serum. There are no other ways to cure the disease.

'''Treatments:'''
* Healer mech serum
* Allowing the pawn to [[Death|die]] again, then resurrecting once more (rerolls the disease)

'''Probability of contracting:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

'''Prevention:'''
* Freeze corpses immediately after death. Corpses placed in a [[sarcophagus]] are still affected by the temperature of the room they are in, and can be removed later but are protected from butchering, hungry animals and assuming you build the sarcophagus from something [[Flammability|non-flammable]], [[fire]].

== Heart attack ==
Heart attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in humans), triggered by the [[Events#Birthday|birthday event]]. There must be 2 or more colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days):
* 0-60% of life expectancy: 99,999,999 - 99,999,999
* 60-80% of life expectancy: 99,999,999 - 2,500
* 80-100% of life expectancy: 2,500 - 300

Examples of intervals and chances:
* 70% of life expectancy (i.e. 56 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
* 90% of life expectancy (i.e. 72 in humans): 1,400 days (approx. 0.000714% per day)

=== Stages ===

* [[Consciousness]] max. 10% (Unconsciousness)
* [[Pain]] +60%
|-
|'''Fatal''' || 100% Severity ||
* [[Death]]
|}

==== Progression ====
Heart attacks always start at 40% severity. Each interval the heart attack severity will randomly change by a value between {{---|40%}} to {{++|60%}}. This means that it is possible for a heart attack to recover on its own, but usually (~76% likelihood){{Check Tag|Detail needed|How is this calculated??}} an untreated heart attack progresses to fatal severity. The interval between changes is random, and varies between {{Ticks|500}} and {{Ticks|10000}}.

==== Treatment ====
Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by {{---|30%}}. Successfully reducing severity below 0% will completely treat the heart attack.

The chance a particular treatment can succeed is 65% multiplied by the [[tend quality]], for an effective maximum of 84.5% with [[glitterworld medicine]].

==== Prevention ====
Replacing a pawn's heart with either a [[prosthetic heart|prosthetic]] or [[bionic heart]] will completely prevent heart attacks. Note however that while the bionic heart improves the [[blood pumping]] capacity, the prosthetic heart decreases it, and thus all of the stats and capacities it affects.

== Version history ==

* [[Version/1.3.3117|1.3.3117]] - Extreme blood loss now reduces consciousness by 40% in addition to setting the capacity's max to 10%. Prior to this, pawns could nonsensically [[Death|die]] by healing from extreme to severe bloodloss if their consciousness was below 40% from other symptoms - extreme would simply max it at 10% but healing to severe would reduce it by 40% to 0% and kill the pawn.
* [[Version/1.4.3523|1.4.3523]] - Sterilized animals no longer lay eggs.

'''Ailments''' are [[health]] conditions that cannot be treated completely using medicine alone.

"MTB" stands for "Mean Time Between", and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

Most permanent ailments are curable with body part replacements or usage of the [[healer mech serum]].

{{Heal Option Table}}

== Chronic ==
Ailments that come with age. Either non-fatal, or progresses extremely slowly towards fatality compared to infectious diseases.

=== Alzheimer's ===
{{stub|reason = "Forget memory" and "confused wandering" mechanics}}
A brain disease usually associated with aging. Alzheimer's disease causes progressive degradation in the ability to think and remember. Patients are known to forget close relatives and sometimes wander around in confusion.

Alzheimer's progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity from when it first appears.

'''Treatment:'''
* [[Luciferium]]: Luciferium removes one randomly selected condition that it can cure every 900,000 to 1,800,000 [[ticks]] (15 - 30 in-game days). Having fewer luciferium-curable conditions will increase the chance that Alzheimer's is chosen, so it can be worth attempting to address any conditions that can be other means. Even with this however, it can take a significant amount of time. Also note that luciferium is a permanent decision - once taken, further doses are necessary to avoid madness and death.
* [[Healer mech serum]]: A healer mech serum will instantaneously heal one condition of the pawn, including Alzheimer's. Which condition is chosen depends on a priority order, with Alzheimer's being a moderately high priority. See the serum's [[Healer mech serum#Summary|condition order]] for details.
* [[Resurrector mech serum]]: Because the resurrector mech serum will replace a destroyed head with a healthy one, it can be used to heal brain ailments, including Alzheimers. Consistently destroying the head can be difficult. With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will do this reliably and safely, but without it, the best way is allowing colonists or animals to eat sections of the corpse, at the risk of consuming the entire body and permanently losing the pawn. Furthermore, no matter how successful the head removal, there is always the risks normally associated with resurrection, including [[dementia]], [[blindness]], and [[resurrection psychosis]]. Note that pawns will initially be incapacitated due to resurrection sickness.
* [[Death refusal]]{{AnomalyIcon}}: Similar to the [[Resurrector mech serum]], a pawn imbued with death refusal can self-resurrect and replace a destroyed head with a healthy one. This comes with the drawback of the pawn losing experience in their skills that happens upon imbuing the death refusal. Pawns resurrected via this method will also have resurrection sickness and a negative [[Mood|moodlet]] upon being resurrected.
* [[Chronophagy]]{{AnomalyIcon}}: As pawns younger than 34 cannot get Alzheimer's, reversing age to younger than that in a Chronophagy ritual will remove it.
* [[Unnatural healing]]{{AnomalyIcon}}: a Creepjoiner with unnatural healing replicates the effect of a healer mech serum and so can be similarly used to cure Alzheimers at the minor risk of replacing an arm with a flesh tentacle for the cured pawn

=== Asthma ===
A chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. Unlike other chronic diseases, asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line.

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity (50%).

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% beginning to regress the stages of asthma (the higher, the better).

{| class="wikitable"

|}

Treatment:
* The severity of asthma can be reduced with treatment, which can be given every 420,000 ticks (around 7 days). One treatment applies to both lungs.
* Asthma can be cured by replacing each affected lung with a [[Lung#Acquisition|healthy replacement]].

A human pawn can first get asthma at any age.

Asthma can also affect animals, domestic, tamed and wild. Domestic and tamed will notify you that they "need treatment", although there apparently is no downside for ignoring that request except slowing them down which may be bad for [[Animals#Training|trained]] or [[pack animal]]s. Similarly, asthmatic wild animals on the map can roam and eat indefinitely without treatment. In fact, wild animals with asthma are easier and slightly safer to hunt, because asthma will reduce their [[move speed]] to 81%, and their [[manipulation]] to only 90%, which makes any counter-attack less effective.

=== Carcinoma ===
{{Stub|section=1|reason=How do the stages progress/occur and what chances and factors affects them?}}
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumors, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed by a skilled doctor or, in some cases, the affected body part can be removed, either by amputation, transplantation of a healthy body part, or replacement by an [[artificial body part]]. Ordinary treatment will prolong the development of a carcinoma or speed up remission, and can be done by doctors of any skill, though better treatment quality is more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.
* When growing, it progresses by 0.003 per day, multiplied by a random factor of 0.45 - 1.65.
* When stable, it neither grows nor regresses on its own.
* When in remission, it regresses by 0.002 per day, multiplied by a random factor of 0.7 - 1.5.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will:
* grow more slowly when in growing stage
:* some slow-growing carcinomas (something less than half) may stop or actually regress (very slowly) during their "growing" stage with good treatment
* slowly regress when stable
* regress quickly when in remission

|}

Treatment:
* Treated every {{ticks|240000}}
* The carcinoma will disappear if severity reaches 0.
* "Excise carcinoma" surgery; this needs 4 medicine of [[medicine|industrial quality]] or above, {{ticks|4500}} of work, and a doctor with a [[medical]] skill of 10 or above. The surgery has a 100% base chance to succeed. If it fails, there is a 25% chance that the patient [[Death|dies]]. Thus, as the maximum [[Doctoring#Success chance|success chance]] is capped at 98%, there is always at least a 0.5% chance of death per attempt.

A human pawn must be at least 22.4 years old to get carcinoma from aging, meaning it can first occur at their 23rd birthday. Carcinomas from other sources, including [[toxic buildup]] and [[nuclear stomach]]s{{RoyaltyIcon}}, can happen at any age. Installed nuclear stomachs create a carcinoma on the torso with an MTB of 120 days.

=== Artery blockage ===
A blockage in one of the critical arteries in the [[heart]]. Heart artery blockages randomly induce [[#Heart attack|heart attacks]]. Artery blockages can be treated by replacing the heart with a [[heart|natural]], [[prosthetic heart|prosthetic]] or [[bionic heart|bionic]] replacement, with a [[healer mech serum]], with [[luciferium]], or with the use of [[biosculpter pod]]'s bioregeneration cycle{{IdeologyIcon}}.

Artery blockages progress by a base of 0.0007 per day, multiplied by a random factor between 0.5 - 3.
This means that artery blockages can take anywhere from 7.9 to 47.6 in-game years from onset to become fatal on its own.

Artery blockages can be treated by replacing the heart.

== Acute ==
Some ailments arise as a result of an acute lack of food or exposure to extreme temperatures. These ailments can only be treated by addressing the underlying cause (e.g. providing food or moving to more comfortable temperatures).

=== Malnutrition ===
When a pawn's [[Eating|food]] meter reaches 0%, they will begin to suffer from [[malnutrition]], shown on the health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

Malnutrition severity without food will advance at an average of 17% per day. There is a variation for each pawn that will vary this by 20% in both directions, meaning a pawn may actually die of malnutrition between 4.9~7.4 days of first having symptoms. There is no stat indicating the specific rate that a pawn may die of malnutrition, but the modified rate is determined for each specific pawn in a given playthrough.
{| class="wikitable"

|}



=== Blood loss ===
{{About|section=1|the effect of already lost blood|the mechanics that cause blood loss|Bleeding}}
A reduction in the normal blood volume. Minor blood loss has relatively mild effects, but as severity increases, the [[consciousness]] rapidly become debilitating. Extreme blood loss leads to [[death]]. Total blood loss is listed under whole body, with a tooltip showing the percent.

Blood loss can occur when a pawn has untreated [[Injury#Bleeding|bleeding injuries]], has had blood harvested for [[hemogen pack]]s,{{BiotechIcon}} or has been fed on by a [[Bloodfeeder]].{{BiotechIcon}} Blood loss from multiple sources stacks additively.

All pawns recover 33.3% of their blood per day, regardless of [[traits]], [[genes]], [[drugs]], or [[artificial body parts]]. All natural blood recovery is stopped when a pawn is [[bleeding]], even in small amounts. Pawns can also recover through a blood transfusion operation, using 1 [[hemogen pack]]{{BiotechIcon}} to recover 35%. The [[Biosculpter_pod#Medic|biosculpter pod's medic cycle]]{{IdeologyIcon}} will also cure all blood loss, though it should be noted that non-transhumanist pawns would recover completely from blood loss in the same time as the cycle takes to complete anyway. If there is no other reason to use the medic cycle, non-transhumanist pawns should just recover outside of the pod and remain productive for that time.

=== Heatstroke ===
Heat stroke occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) above their [[maximum comfortable temperature]], and recovery occurs in temperatures less than the maximum comfortable temperature.
Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.

Pawns additionally take periodic burn damage in temperatures more than 150°C (270°F) above their maximum comfortable temperature.
====Severity Increase====

The procedure for determining severity growth every 60-tick interval is given by:
# Take the amount by which the ambient temperature exceeds the pawn's maximum safe temperature (which is the maximum comfortable temperature +10°C).
# Pass the amount through the curve shown below to obtain the effective temperature excess. Note that for amounts from 0 to 25 °C, this doesn't result in a change.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval (60 ticks, 1 second).
# If the growth is less than <code>0.000375</code>, set it to that number. This sets a minimum amount the severity increases by for temperatures in the range of 10 to 15.814°C above the maximum comfortable temperature.
:<code>Increase in heatstroke severity every 60 ticks = max(0.000375, 0.0000645×effective_temperature_curve(<i>ambient_temperature</i> - (<i>maximum_comfortable_temperature</i> + 10°C)))</code>
::<code><i>where </i>effective_temperature_curve()<i> is a post-processing curve with points</i>: (0, 0), (25, 25), (50, 40), (100, 60), (200, 80), (400, 100), (4000, 1000).</code>

====Severity Decrease====
If the ambient temperature is less than the maximum comfortable temperature, the amount the severity will decrease every 60-tick interval is given by:
:<code>Decrease in heatstroke severity every 60 ticks = max(0.0015, min(0.015, 0.027×heatstroke_severity))</code>
This means that as long as the ambient temperature is less than the maximum comfortable temperature, heatstroke recovery is independent of temperature, but severity decreases at its fastest when it is above 50%, and at its slowest below 5.6%. Full recovery from near-100% severity occurs after 151 real-time seconds, or 3.6 in-game hours.

=== Hypothermia ===
Hypothermia occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) below their [[minimum comfortable temperature]]. [[Insectoids]] don't experience hypothermia, but instead get [[hypothermic slowdown]].

Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Hypothermic slowdown ===
{{quote|A special biological state used by some creatures to survive extreme cold. Instead of trying to stay warm, the creature's body chemistry adapts to prevent internal freezing despite very low temperature. Bodily functions are slowed and capacities are reduced, but the cold does no permanent damage. Some biologists call it a wakeful form of hibernation.}}

[[Insectoids]] avoid hypothermia and experience hypothermic slowdown instead with similar penalties but avoiding death at 100% and no [[frostbite]].

Slowdown value increases many times above 100% with apparently no upper limit. When defrosting insects this total value is used so defrost time is proportional to total time frozen.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.

=== Vacuum exposure ===
{{Odyssey|section=1}}
Vacuum exposure occurs when a pawn is subjected to [[Orbit|hard vacuum]] without adequate protection.

The rate of severity growth is directly proportional to the vacuum percentage of the pawn's current tile, and to the difference between 1 and a pawn's [[vacuum resistance]] stat. Vacuum will be 100% outside pressurized rooms; otherwise, it will vary depending on the presence of [[oxygen pump]]s, open connections to other rooms, and so on. The specific algorithm is:
# Start with a default of 2% per second.
# Multiply the amount by the tile's current vacuum percentage.
# Multiply the product by the difference between 1 and the pawn's vacuum resistance.
Expressed as a formula, the increase of severity every {{ticks|60}} is:
:<code>Increase in vacuum exposure severity = 0.02 * tile vacuum percentage * (1 - vacuum resistance)</code>

Vacuum exposure builds up extremely quickly in pawns without significant vacuum resistance. An unprotected pawn with no resistance will die in just {{ticks|3000}} of exposure to a complete vacuum, making even brief spacewalks a risky prospect.

Pawns recover quickly from vacuum exposure while inside a pressurized area; severity will simply fall at a flat 10% per second until the condition disappears entirely. Affected pawns that reach 100% vacuum resistance while still exposed (such as by equipping a [[vacsuit]]) will keep their current level of exposure until they return to a pressurized tile, but its severity will not increase any further.

{{quote|This creature is gestating offspring. It will give birth if the pregnancy comes to term. If starved or injured, there may be a miscarriage.|Description}}

Tamed, non-[[human]], non-[[insectoid]], non-[[egg]]laying, female [[animals]] have a 50% chance to get pregnant from [[Animals#Mating|mating]]. While this is not an ailment in the traditional sense, it does have mechanical effects. For the first {{ticks|600}} this condition will be invisible, after which point a message will come up mentioning the pregnancy.

Humans can be pregnant only if the [[Biotech DLC]]{{BiotechIcon}} is enabled. They have a different list of symptoms. See [[Reproduction]] for details.

A pregnant animal suffering from [[malnutrition]] of 25% or higher or that is injured may miscarry. Miscarriages are noted by an in-game message.

Some animals will give birth to multiple young. The probability of this is determined by a curve, and is different for each animal.

The duration, and thus the severity gain per day, depends on the gestation time of the animal in question.

=== Sterilized ===
{{Stub|section=1|reason=Missing details, sources, mechanics etc. Are there any other causes in humans?}}
{{Quote|This creature's reproductive system has been permanently shut down.|Description}}
[[Animals]] can be sterilized by use of the "Sterilize" [[operation]] to prevent them from being able to reproduce, and the sterilized animal won't attempt to mate with others nor will others attempt to mate with it. [[Egg]] laying animals will stop laying eggs when sterilized. The animal acts as normal in all other ways, including [[milk]] production.

Sterilizing a pregnant animal will not terminate the pregnancy.

The sterilization operation requires [[Medical]] skill of 3 and {{ticks|500}} of work.

Humans with the "Sterilized" health trait can only be healed with a [[healer mech serum]]. Pawns can{{Check Tag|Will?|Is it all failures or just a chance?}} receive the sterilized ailment from a failed vasectomy or IUD insertion.{{BiotechIcon}} It is currently unknown if there are other sources.

== Drug damage ==
These ailments are caused by excess drug use.

=== Cirrhosis ===
A degenerative [[liver]] disease caused by excessive [[alcohol]] consumption.
An otherwise healthy pawn with cirrhosis will have an [[immunity gain speed]] of 70%, making them extremely vulnerable to disease.

Treatment:
* The easiest method of treatment is the [[Organ harvesting|transplantation]] of a new liver. Due to the extreme vulnerability to disease, even if your colony dislikes organ harvesting it may be worth it to replace the livers of valuable pawns as doctors will struggle to get high enough tend qualities on diseases to counterbalance the decreased immunity gain, often needing a very good hospital plus a very good doctor or [[glitterworld medicine]] to do so.
* Other than transplantation, only [[healer mech serum]] and [[unnatural healing]]{{AnomalyIcon}} can cure cirrhosis.

Alcohol [[tolerance]] above '''45%''' imposes a chance to get [[cirrhosis]] in the liver proportional to the tolerance held.

* Kidney chemical damage can be cured by replacing with a non-damaged [[kidney]] or with a [[detoxifier kidney]]{{BiotechIcon}}

==Trauma savant==

{| class="wikitable"

* Nullifies all opinions of other pawns
|}

The chance to receive trauma savant on any physical (non-chemical) [[injury]] to the brain is equal to the percentage of the brain damaged multiplied by 0.12. For an adult human, this represents 1.2% chance per point of damage. Animals can also become trauma savants.

A [[Ghoul|Ghoul]]{{AnomalyIcon}} or a humans with the [[Scarless]]{{BiotechIcon}} gene will not get brain scars from damage to their brain, but they still have a chance to become trauma savants. This makes it possible to voluntarily give the condition to a pawn by repeatedly damaging and healing their brain, although this can be time consuming and expensive. For an adult human, the brain will need to take on average 83 points of damage. Using other methods to heal the brain such as the [[Biosculpter pod#Bioregeneration|Bioregeneration cycle]] of the [[biosculpter pod]]{{IdeologyIcon}} is theoretically possible, but prohibitively expensive.

Currently, the most cost-effective known method to damage the brain is to purposefully fail the surgery to remove a [[Painstopper|painstopper]]. Painstoppers are the cheapest brain implant that can be removed. Attempting to remove it costs only one [[herbal medicine]] and failing will not destroy the implant. Performing the operation outside, on a [[Sleeping spot]] or an [[Ancient bed]],{{IdeologyIcon}} in the dark, with a low level surgeon with lowered Sight and Manipulation will maximize the chance for the operation to fail. If the operation accidentally succeeds, then the patient should be moved to a high quality hospital to reinsert the painstopper, as failure would destroy the implant and greatly increase the overall cost. It takes on average between 50 and 100 failed brain operations for a patient to become trauma savant.

Trauma savant negates the [[consciousness]] penalty from all brain damage, including scars that existed before the condition. On another hand, those brain scars will still lower the brain's health and can potentially still cause pain. Also, Trauma savant will not prevent loss of consciousness from other brain conditions like Dementia.

Trauma savant can be healed with a [[healer mech serum]] or the [[Unnatural healing]]{{AnomalyIcon}} ability (or possibly through other means as well). It can also be treated by killing the pawn, [[Skull|removing their skull]]{{IdeologyIcon}} then resurrecting thanks to a [[Resurrector mech serum]] or [[death refusal]]{{AnomalyIcon}}.

==Bliss lobotomy==
{{Anomaly|section = 1}}
{{Main|Bliss lobotomy}}
A whole-body condition that gives a constant +20 mood bonus but imposes a -50% global learning factor penalty. Makes pawn incapable of cooking, construction, plant work, mining, crafting and intellectual. Can generate on [[horax cult|cultist]] raiders or be deliberately induced via a brain surgery at the cost of 2 medicine and 30 [[bioferrite|bioferrites]].

== General ==
These ailments appear in gameplay, and usually wear off on their own (except death-causing ones).

=== Cryptosleep sickness ===
After-effects of using a cryptosleep pod. Cryptosleep suspends and replaces many bodily functions in order to prevent aging and death. Upon exiting cryptosleep, the body takes time to restart and rebalance its natural metabolic processes. While this is ongoing, the patient suffers from nausea, dizziness, and a sense of fuzziness in the mind.

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists in the "[[Crashlanded]]" scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

Treatment:

=== Food poisoning ===
Occurs after eating a contaminated meal or occasionally from raw food. The chance of contamination for cooked meals is primarily determined by the cook's [[food poison chance]] stat, with the [[Cleanliness|cleanliness of the room]] where it was prepared also being a potential factor.

[[Corpse]]s have a flat chance of 5% to give food poisoning. Other raw food has a flat chance in between 1% and 4% depending on the type of food — most raw food having a 2% chance. Cooked meals roll two separate probabilities to determine if the food is poisoned. The first checks the [[cleanliness]] of the kitchen used. See the accompanying graph for specifics. Note that cleanliness above -2 prevents this roll from producing poisoned meals. If the cooking station is outdoors, the default chance is 2%.

If the first roll fails to poison the meal, then a second roll is performed, this time based on the [[food poison chance]] of the pawn, controlled entirely by their [[Cooking|cooking skill]].
If the second roll indicates that the meal is poisonous, the probability of poisoning the pawn is 100% for that individual meal. However, when the poisonous meal is part of a stack with other meals, the probability is distributed among all the meals in the stack. This distribution reduces the chance of food poisoning from 100% to the ratio of total meals to poisonous meals within the stack. For instance, if a poisonous meal is placed on top of a stack containing three non-poisonous meals, the probability for each meal to poison the pawn becomes 25%. Consequently, even if the original meal was poisonous, there is a possibility that no pawns will experience food poisoning.

Because of the penalty to [[blood filtration]] and [[consciousness]], food poisoning in combination with other ailments such as an [[infection]] can be a cause for concern.

; Symptoms and progress:
Food poisoning lasts 24 hours with no after-effects. It has 3 stages: the first unpleasant 4 hours, followed by a crippling 16 hours, and finally an unpleasant 4 hours largely similar to the first stage, as described in the table below.

|}
; Treatment and Prevention
Food poisoning can only be minimized by manipulating the factors that cause it mentioned above. Prevention can only be guaranteed by exclusively consuming meals purchased from traders or by making [[Baby food]] or [[nutrient paste meal]]s as they will never cause food poisoning. Installing a [[sterilizing stomach|sterilizing]] {{RoyaltyIcon}}, [[nuclear stomach]] {{RoyaltyIcon}} or [[fleshmass stomach]] {{AnomalyIcon}}, or having the [[strong stomach]] gene{{BiotechIcon}} render pawns immune to contracting food poisoning. Note that [[bionic stomach]]s reduce the chance of getting food poisoning by 50% but cannot outright prevent it.

The notification for a colonist being poisoned will explain the cause of the poisoning. This can be very helpful if an unattended kitchen was allowed to cross into the very dirty -2 cleanliness danger zone, as a nearby cleaner can simply be ordered to clean the kitchen and avoid more unnecessary poisoning.

There is no practical treatment for food poisoning, you simply have to let it run its course. [[Healer mech serum]] will cure it (if there is nothing worse to cure), but this costly measure is rarely if ever worthwhile, as food poisoning only affects the pawn for the 24 hour cycle and then leaves them as healthy as they were before. [[Unnatural healing]]{{AnomalyIcon}} is the vastly more economical option, though it carries opportunity cost of the 6 day cooldown.

Because of the high chance of [[vomiting]] at any moment, putting the patient on a temporary diet of [[pemmican]] may be useful. Vomiting interrupts the process of eating, resetting it to the start, but a colonist can more quickly consume several pieces of pemmican between "attacks" that they can eat an entire [[meal]]. This allows the poisoned pawn to more easily avoid malnutrition without feeding them [[raw food]]s that could cause further poisoning.

=== Toxic buildup ===
{{Stub|section=1|reason=What is the effect of Toxic Environment Resistance vs Toxic Resistance, tox rain}}
Primarily occurs with exposure to [[toxic fallout]], [[pollution]],{{BiotechIcon}} and [[tox gas]].{{BiotechIcon}}. Prolonged exposure gradually increases the buildup severity.

Alternatively, some attacks cause instantaneous increases in toxic buildup severity, such as [[cobra]] and [[waste rat]] {{BiotechIcon}} bites, the [[venom talon]] {{RoyaltyIcon}}, or [[venom fangs]] {{RoyaltyIcon}}.

A colonist under a roof is protected from toxic fallout, and avoiding interaction with the other sources can prevent buildup from them. If they are exposed to the fallout, they will accumulate Toxic Buildup at a rate of 40% per day. Pollution will accumulate at the same rate, but cannot be mitigated through roofing. When walking through polluted terrain in [[caravan]]s, they will accumulate buildup at 20% per day in Moderately Polluted terrain (50%-75% polluted tiles) and 40% per day in Extremely Polluted terrain (above 75%). Buildup from both pollution as well as toxic fallout can stack, meaning a pawn standing in polluted terrain while a toxic fallout can gain 80%/day.

This buildup severity gained is proportional to the [[Toxic Resistance]] [[stat]] - thus, [[human]]s buildup at the full rate, [[animal]]s at half, and [[insects]] and [[mechanoids]] are immune.{{Check Tag|Body Size?|Buildup severities from Damage types are now inversely proportional to body size, are all sources scaled? Either way, add detail}} Buildup can also be reduced through a variety of of other means including items such as the [[gas mask]] {{BiotechIcon}}, [[detoxifier kidney]] {{BiotechIcon}}, and [[detoxifier lung]] {{BiotechIcon}}, as well as [[genes]]{{BiotechIcon}} such as [[Partial antitoxic lungs]]{{BiotechIcon}} and [[Total antitoxic lungs]],{{BiotechIcon}} or [[Tox resistance]]{{BiotechIcon}} and [[Tox immunity]].{{BiotechIcon}}

There is, effectively, a multiplier for each pawn on their toxic buildup accumulation from these indirect sources. This can vary between 15% faster buildup or 15% slower buildup than the average rate. There is no stat in the information panel to convey this variation, but it is static for a given pawn. This means that baseliner humans standing in pollution and a toxic fallout, with no Tox Resistance of any sort, can vary from either 68% to 92% buildup per day, rather than a constant 80%.

The buildup severity occurs in stages. The later stages cause permanent [[#Dementia|dementia]] which does not wear off even after toxic buildup subsides. When a pawn affected by toxic buildup [[Death|dies]], there is a chance that its corpse will instantly rot - this chance is equal to the severity.

Once a colonist returns to a safe area, such as a roofed area for toxic fallout, or otherwise stops taking severity increases, their buildup severity will gradually decrease. Once no longer exposed, severity reduces by 8% per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach high stages of toxic buildup are likely to develop further complications.

{{Biotech|section=1}}
{{quote|"This person was in a growth vat which wasn't functioning properly due to lack of power or nutrition feedstock. This has left their body in a state of bio-starvation."|In-game description}}
A pawn in a [[growth vat]] with no power or nutrition, will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. These include:
* [[Pain]]: {{++|15%}}
* [[Hunger Rate Factor]] offset: {{++|50%}}
* [[Consciousness]]: {{--|25%}}

=== Vomiting ===
{{Stub|section=1|reason=what does it interrupt, what happens when different tasks are underway - e.g. eating cancels the eating task but doesn't waste the meal, explanation that vomiting is expressed as mtb etc}}
The body attempting to forcefully expunge toxins. Unfortunately for your pawns, this doesn't work in Rimworld.

Vomiting is caused by a wide variety of ailments{{Check Tag|List Needed?}}, some [[Psycasts]]{{RoyaltyIcon}}, or being hit with an EMP while having the [[Sterilizing stomach|Sterilizing]], [[Reprocessor stomach|Reprocessor]], or [[Nuclear stomach|Nuclear]] stomachs{{RoyaltyIcon}} installed.

A pawn that is vomiting will stop in place, face the side, and begin vomiting. Vomiting lasts a random duration from {{Ticks|300}} to {{Ticks|900}}, and every 150 interval ticks it reduces the pawn's food bar by 0.04 and generates 1 stack of [[vomit]] filth on the tile they're facing. Note that this interval tick occurs independently from the beginning of the vomiting duration, and as such the number of times it occurs may not be the simple division of the chose duration divided by 150. As such, between one fewer and one more interval may occur than the the division would indicate. A pawn lying in a bed will not stand up to vomit{{Check Tag|Details|Does this pause the resting bonus from lying down? Does it wake them up?}}.

Vomiting will interrupt most tasks, including eating, walking, aiming a weapon, or working at a station, but they will resume the task once they stop vomiting{{Check Tag|Mechanics|Do pawns who are actively vomiting still reserve the task they were working on?}}. For this reason, it is recommended that pawns who are afflicted with an ailment that causes frequent vomiting, such as [[food poisoning]], eat foods like [[pemmican]], as a pawn who vomits while in the middle of eating a normal meal will lose all progress towards consuming it (note that the meal is not wasted), but a pawn eating pemmican will still consume part of the stack. Similarly, they should also avoid long tasks that have their progress reset on being interrupted, such as cooking 4x [[lavish meal]]s.

=== Crumbling mind ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}

The gradual breakdown of the mind. While technically non-fatal, it applies mounting consciousness penalties, and its final stage renders a pawn incapable of nearly all work.

Crumbling mind is caused by two [[Anomaly]] events - The [[Corrupted obelisk]] and the [[Creepjoiner]]. It cannot affect pawns that existed before those events, only ones created by them. It can be detected before ailments show by a surgical inspection.

Creepjoiners with this condition will begin showing symptoms within 2-3.33 days. Duplicated pawns will begin showing them within 12-48 hours. Severity progresses by 33% per day. Progress can be paused through the use of a [[cryptosleep casket]].

Crumbling mind can be cured by a [[healer mech serum]] as well as the [[unnatural healing]] ability so long as it hasn't progressed to the final stage of '''Crumbled mind'''. Once it has, the condition is incurable, short of destroying the colonists brain then resurrecting them with either a [[resurrector mech serum]] or [[death refusal]]. However, consistently destroying the brain can be difficult. There are 5 main ways to archive it:
* With the [[Biotech DLC]], using a [[Subcore ripscanner]] on the colonist in question will kill it by destroying its brain.
* Also with the Biotech DLC, extracting the pawn's genes with a [[Gene extractor]] while the '''Genes Regrowing''' Hefiff remains active will kill it by brain destruction.
* With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will destroy its head reliably and safely.
* Fatal [[Luciferium]] withdraw kills by destroying the brain.
* Allow colonists or animals to eat sections of the corpse, risking consuming the entire body before the head is removed.

Furthermore, no matter how successful the head removal, the costs and downsides of the either the serum or refusal remain. If this strategy is used, remember not to euthanize them or they will be no longer of your faction after resurrection.

Counterintuitively, [[Ghoul|ghoul infusion]] will not cure crumbling mind and it will hinder ghoul's combat abilities.

=== Duplicate sickness ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}
Psychic interference between this person and their duplicate is causing slow mental deterioration. As long as multiple copies of this person are alive, the condition will keep getting worse. However, the condition will not be lethal.

Duplicate sickness is one of the potential outcomes from the duplication of a pawn by a [[corrupted obelisk]]. It affects both the original pawn and the duplicate{{Check Tag|Wb other duplicates?|Test both a previous duplicate (i.e. use obelisk gizmo, wait cooldown use again) and mass cloning (i.e. when 30 pawns spawn when it reaches max activity}} and is initially hidden. Severity increases by 10% per day that both pawns are alive{{Check Tag|Wb in crypto?|Does severity increase if the pawn is in cryptosleep? If no, does it pause on both or just the one in crypto? If no, wb if both are in crypto?}} and gradually reduces the consciousness of both pawns and makes them more likely to have [[mental breaks]], before eventually rendering both comatose.

It cannot be treated,{{Check Tag|Verify}} but can be cured by one of three methods: [[healer mech serum]], the [[unnatural healing]] ability, or the death of one of the two pawns.

If one of the two connected pawns is killed, the other's duplication sickness severity immediately starts regressing at the rate of 50% per day, while the killed pawn's duplication sickness is instantly cured. The killed pawn can then be immediately resurrected with a [[resurrector mech serum]] or [[death refusal]] without stopping the regression of the other pawn's sickness. Similarly, if one of the linked pawns is turned into a [[ghoul]], killed, and revived with a [[ghoul resurrection serum]], the same mechanics apply.

== Surgical ==
These ailments happen with medical operations.

=== Anesthetic ===
Used in surgery to make sure that a pawn is unconscious. It can also be administered outside of operations using a medical bill, consuming medicine.

A pawn under anesthesia is unconscious for the first 6 hours, and the worst effects of anesthetic wear off after 12 hours, so arranging operations to be performed some time just before a pawn needs to sleep is recommended if you want them functioning the next work day.

Treatment:
* Wears off on its own between {{ticks|45000}} to {{ticks|75000}} even if severity has not reached 0%
** Surgery is unaffected even if it wears off before finished

==== Version history ====
Prior to 1.1 it lasted only {{ticks|15000}} and did not have any other stages afterwards.

== Resurrection ==
These may occur after a dose of [[resurrector mech serum]] is applied on a [[Death|dead]] pawn.

=== Resurrection sickness ===
After-effects of being resurrected by mechanite injection. Artificially-kickstarted body processes take time to rebalance themselves.

'''Treatment:'''
* Wears off anywhere from {{ticks|90000}} to {{ticks|150000}}

'''Probability:'''
* 100% chance of being applied

=== Blindness ===
Mechanites fail to properly repair the eyes, instead causing more damage to it, resulting in blindness.

Blindness from [[resurrector mech serum]] applies to both eyes, resulting in total blindness

{| class="wikitable"

'''Treatment:'''
* Replace eyes with [[bionic eye]]s or [[archotech eye]]s

'''Probability:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

=== Resurrection psychosis ===
Chaotic thought patterns caused by the decoherence of resurrection mechanites. Resurrection psychosis progresses and eventually causes total psychosis and [[death]].

The severity of the psychosis increases by 0.01 per day, meaning that it will kill in 100 days after resurrection, or 90 days after this ailment becoming visible. Hopefully this gives you enough time to find a [[healer mech serum]] to heal the ailment, find another [[resurrector mech serum]] to attempt the resurrection again once the psychosis has run its course, or build a [[cryptosleep casket]] to give you time to find either serum. There are no other ways to cure the disease.

'''Treatments:'''
* Healer mech serum
* Allowing the pawn to [[Death|die]] again, then resurrecting once more (rerolls the disease)

'''Probability of contracting:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

'''Prevention:'''
* Freeze corpses immediately after death. Corpses placed in a [[sarcophagus]] are still affected by the temperature of the room they are in, and can be removed later but are protected from butchering, hungry animals and assuming you build the sarcophagus from something [[Flammability|non-flammable]], [[fire]].

== Heart attack ==
Heart attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in humans), triggered by the [[Events#Birthday|birthday event]]. There must be 2 or more colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days):
* 0-60% of life expectancy: 99,999,999 - 99,999,999
* 60-80% of life expectancy: 99,999,999 - 2,500
* 80-100% of life expectancy: 2,500 - 300

Examples of intervals and chances:
* 70% of life expectancy (i.e. 56 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
* 90% of life expectancy (i.e. 72 in humans): 1,400 days (approx. 0.000714% per day)

=== Stages ===
{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms
|-
|'''Painful''' || 0% Severity ||
* [[Consciousness]] ×50%
* [[Pain]] +40%
|-
|'''Debilitating''' || 60% Severity ||
* [[Consciousness]] max. 10% (Unconsciousness)
* [[Pain]] +60%
|-
|'''Fatal''' || 100% Severity ||
* [[Death]]
|}

==== Progression ====
Heart attacks always start at 40% severity. Each interval the heart attack severity will randomly change by a value between {{---|40%}} to {{++|60%}}. This means that it is possible for a heart attack to recover on its own, but usually (~76% likelihood){{Check Tag|Detail needed|How is this calculated??}} an untreated heart attack progresses to fatal severity. The interval between changes is random, and varies between {{Ticks|500}} and {{Ticks|10000}}.

==== Treatment ====
Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by {{---|30%}}. Successfully reducing severity below 0% will completely treat the heart attack.

The chance a particular treatment can succeed is 65% multiplied by the [[tend quality]], for an effective maximum of 84.5% with [[glitterworld medicine]].

==== Prevention ====
Replacing a pawn's heart with either a [[prosthetic heart|prosthetic]] or [[bionic heart]] will completely prevent heart attacks. Note however that while the bionic heart improves the [[blood pumping]] capacity, the prosthetic heart decreases it, and thus all of the stats and capacities it affects.

== Version history ==
* [[Version/0.7.581|0.7.581]] Added with cataracts and bad back
* [[Version/0.8.657|0.8.657]] - Added hypothermia, frostbite, heatstroke, and burns from being in areas with extreme temperatures.

* [[Version/0.10.785|0.10.785]] - Starvation and blood loss are now staged and affect consciousness as they worsen.
* [[Version/0.12.906|0.12.906]] - All organisms including animals have life expectancies and will develop chronic conditions like frailty or cataracts in old age. Heart attacks added.
* [[Version/0.13.1135|0.13.1135]] - Carcinoma, asthma, and hearing loss added.
* [[Version/1.0.0|1.0.0]] - Minor starvation (below 25% severity) no longer causes miscarriages.
* [[Version/1.1.0|1.1.0]] - Pregnant animal is no longer viewed as sick because pregnancy affects its capacities. and thus now sells for the same as one with no health conditions.
* [[Version/1.3.3117|1.3.3117]] - Extreme blood loss now reduces consciousness by 40% in addition to setting the capacity's max to 10%. Prior to this, pawns could nonsensically [[Death|die]] by healing from extreme to severe bloodloss if their consciousness was below 40% from other symptoms - extreme would simply max it at 10% but healing to severe would reduce it by 40% to 0% and kill the pawn.
* [[Version/1.4.3523|1.4.3523]] - Sterilized animals no longer lay eggs.
* [[Version/1.6.4518|1.6.4518]] - Vacuum exposure implemented with [[Odyssey]].

'''Ailments''' are [[health]] conditions that cannot be treated completely using medicine alone.

"MTB" stands for "Mean Time Between", and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

Most permanent ailments are curable with body part replacements or usage of the [[healer mech serum]].

{{Heal Option Table}}

== Chronic ==
Ailments that come with age. Either non-fatal, or progresses extremely slowly towards fatality compared to infectious diseases.

=== Alzheimer's ===
{{stub|reason = "Forget memory" and "confused wandering" mechanics}}
A brain disease usually associated with aging. Alzheimer's disease causes progressive degradation in the ability to think and remember. Patients are known to forget close relatives and sometimes wander around in confusion.

Alzheimer's progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity from when it first appears.

'''Treatment:'''
* [[Luciferium]]: Luciferium removes one randomly selected condition that it can cure every 900,000 to 1,800,000 [[ticks]] (15 - 30 in-game days). Having fewer luciferium-curable conditions will increase the chance that Alzheimer's is chosen, so it can be worth attempting to address any conditions that can be other means. Even with this however, it can take a significant amount of time. Also note that luciferium is a permanent decision - once taken, further doses are necessary to avoid madness and death.
* [[Healer mech serum]]: A healer mech serum will instantaneously heal one condition of the pawn, including Alzheimer's. Which condition is chosen depends on a priority order, with Alzheimer's being a moderately high priority. See the serum's [[Healer mech serum#Summary|condition order]] for details.
* [[Resurrector mech serum]]: Because the resurrector mech serum will replace a destroyed head with a healthy one, it can be used to heal brain ailments, including Alzheimers. Consistently destroying the head can be difficult. With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will do this reliably and safely, but without it, the best way is allowing colonists or animals to eat sections of the corpse, at the risk of consuming the entire body and permanently losing the pawn. Furthermore, no matter how successful the head removal, there is always the risks normally associated with resurrection, including [[dementia]], [[blindness]], and [[resurrection psychosis]]. Note that pawns will initially be incapacitated due to resurrection sickness.
* [[Death refusal]]{{AnomalyIcon}}: Similar to the [[Resurrector mech serum]], a pawn imbued with death refusal can self-resurrect and replace a destroyed head with a healthy one. This comes with the drawback of the pawn losing experience in their skills that happens upon imbuing the death refusal. Pawns resurrected via this method will also have resurrection sickness and a negative [[Mood|moodlet]] upon being resurrected.
* [[Chronophagy]]{{AnomalyIcon}}: As pawns younger than 34 cannot get Alzheimer's, reversing age to younger than that in a Chronophagy ritual will remove it.
* [[Unnatural healing]]{{AnomalyIcon}}: a Creepjoiner with unnatural healing replicates the effect of a healer mech serum and so can be similarly used to cure Alzheimers at the minor risk of replacing an arm with a flesh tentacle for the cured pawn

=== Asthma ===
A chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. Unlike other chronic diseases, asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line.

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity (50%).

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% beginning to regress the stages of asthma (the higher, the better).

{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms

| '''Asthma (major)''' || ≥ 45% severity || -50% part efficiency
|}

Treatment:
* The severity of asthma can be reduced with treatment, which can be given every 420,000 ticks (around 7 days). One treatment applies to both lungs.
* Asthma can be cured by replacing each affected lung with a [[Lung#Acquisition|healthy replacement]].

A human pawn can first get asthma at any age.

|}

Asthma can also affect animals, domestic, tamed and wild. Domestic and tamed will notify you that they "need treatment", although there apparently is no downside for ignoring that request except slowing them down which may be bad for [[Animals#Training|trained]] or [[pack animal]]s. Similarly, asthmatic wild animals on the map can roam and eat indefinitely without treatment. In fact, wild animals with asthma are easier and slightly safer to hunt, because asthma will reduce their [[move speed]] to 81%, and their [[manipulation]] to only 90%, which makes any counter-attack less effective.

=== Bad back ===

Cataracts can be cured through the following methods:
* Replacing the affected eyes with a [[bionic eye|bionic]] or [[archotech eye|archotech]] eye.
* Use of a [[healer mech serum]] which will heal cataracts in both eyes at once
* Via [[luciferium]] use. Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.
* Through the use of the [[biosculpter pod]]'s bioregeneration cycle.{{IdeologyIcon}}
* Via the [[Scarless]] gene.{{BiotechIcon}} Note that this does not occur instantaneously, but instead at healing instances that occur periodically. See that page for details.

=== Carcinoma ===
{{Stub|section=1|reason=How do the stages progress/occur and what chances and factors affects them?}}
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumors, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed by a skilled doctor or, in some cases, the affected body part can be removed, either by amputation, transplantation of a healthy body part, or replacement by an [[artificial body part]]. Ordinary treatment will prolong the development of a carcinoma or speed up remission, and can be done by doctors of any skill, though better treatment quality is more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.
* When growing, it progresses by 0.003 per day, multiplied by a random factor of 0.45 - 1.65.
* When stable, it neither grows nor regresses on its own.
* When in remission, it regresses by 0.002 per day, multiplied by a random factor of 0.7 - 1.5.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will:
* grow more slowly when in growing stage
:* some slow-growing carcinomas (something less than half) may stop or actually regress (very slowly) during their "growing" stage with good treatment
* slowly regress when stable
* regress quickly when in remission
{| class="wikitable"

* Acute pain (+60%)
* -90% part efficiency
|-
| '''Carcinoma (extreme)''' || 100% severity ||
* Affected part is destroyed
|}

Treatment:
* Treated every {{ticks|240000}}
* The carcinoma will disappear if severity reaches 0.
* "Excise carcinoma" surgery; this needs 4 medicine of [[medicine|industrial quality]] or above, {{ticks|4500}} of work, and a doctor with a [[medical]] skill of 10 or above. The surgery has a 100% base chance to succeed. If it fails, there is a 25% chance that the patient [[Death|dies]]. Thus, as the maximum [[Doctoring#Success chance|success chance]] is capped at 98%, there is always at least a 0.5% chance of death per attempt.

A human pawn must be at least 22.4 years old to get carcinoma from aging, meaning it can first occur at their 23rd birthday. Carcinomas from other sources, including [[toxic buildup]] and [[nuclear stomach]]s{{RoyaltyIcon}}, can happen at any age. Installed nuclear stomachs create a carcinoma on the torso with an MTB of 120 days.

=== Dementia ===
Dementia is simply the functionality of the brain declining, and affects all cognitive functions.

=== Artery blockage ===
A blockage in one of the critical arteries in the [[heart]]. Heart artery blockages randomly induce [[#Heart attack|heart attacks]]. Artery blockages can be treated by replacing the heart with a [[heart|natural]], [[prosthetic heart|prosthetic]] or [[bionic heart|bionic]] replacement, with a [[healer mech serum]], with [[luciferium]], or with the use of [[biosculpter pod]]'s bioregeneration cycle{{IdeologyIcon}}.

Artery blockages progress by a base of 0.0007 per day, multiplied by a random factor between 0.5 - 3.
This means that artery blockages can take anywhere from 7.9 to 47.6 in-game years from onset to become fatal on its own.

Artery blockages can be treated by replacing the heart.

Some ailments arise as a result of an acute lack of food or exposure to extreme temperatures. These ailments can only be treated by addressing the underlying cause (e.g. providing food or moving to more comfortable temperatures).

=== Malnutrition ===
When a pawn's [[Eating|food]] meter reaches 0%, they will begin to suffer from [[malnutrition]], shown on the health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

Malnutrition severity without food will advance at an average of 17% per day. There is a variation for each pawn that will vary this by 20% in both directions, meaning a pawn may actually die of malnutrition between 4.9~7.4 days of first having symptoms. There is no stat indicating the specific rate that a pawn may die of malnutrition, but the modified rate is determined for each specific pawn in a given playthrough.

=== Blood loss ===
{{About|section=1|the effect of already lost blood|the mechanics that cause blood loss|Bleeding}}
A reduction in the normal blood volume. Minor blood loss has relatively mild effects, but as severity increases, the [[consciousness]] rapidly become debilitating. Extreme blood loss leads to [[death]]. Total blood loss is listed under whole body, with a tooltip showing the percent.

Blood loss can occur when a pawn has untreated [[Injury#Bleeding|bleeding injuries]], has had blood harvested for [[hemogen pack]]s,{{BiotechIcon}} or has been fed on by a [[Bloodfeeder]].{{BiotechIcon}} Blood loss from multiple sources stacks additively.

All pawns recover 33.3% of their blood per day, regardless of [[traits]], [[genes]], [[drugs]], or [[artificial body parts]]. All natural blood recovery is stopped when a pawn is [[bleeding]], even in small amounts. Pawns can also recover through a blood transfusion operation, using 1 [[hemogen pack]]{{BiotechIcon}} to recover 35%. The [[Biosculpter_pod#Medic|biosculpter pod's medic cycle]]{{IdeologyIcon}} will also cure all blood loss, though it should be noted that non-transhumanist pawns would recover completely from blood loss in the same time as the cycle takes to complete anyway. If there is no other reason to use the medic cycle, non-transhumanist pawns should just recover outside of the pod and remain productive for that time.

=== Heatstroke ===
Heat stroke occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) above their [[maximum comfortable temperature]], and recovery occurs in temperatures less than the maximum comfortable temperature.
Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.

Pawns additionally take periodic burn damage in temperatures more than 150°C (270°F) above their maximum comfortable temperature.
====Severity Increase====

The procedure for determining severity growth every 60-tick interval is given by:
# Take the amount by which the ambient temperature exceeds the pawn's maximum safe temperature (which is the maximum comfortable temperature +10°C).
# Pass the amount through the curve shown below to obtain the effective temperature excess. Note that for amounts from 0 to 25 °C, this doesn't result in a change.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval (60 ticks, 1 second).
# If the growth is less than <code>0.000375</code>, set it to that number. This sets a minimum amount the severity increases by for temperatures in the range of 10 to 15.814°C above the maximum comfortable temperature.
:<code>Increase in heatstroke severity every 60 ticks = max(0.000375, 0.0000645×effective_temperature_curve(<i>ambient_temperature</i> - (<i>maximum_comfortable_temperature</i> + 10°C)))</code>
::<code><i>where </i>effective_temperature_curve()<i> is a post-processing curve with points</i>: (0, 0), (25, 25), (50, 40), (100, 60), (200, 80), (400, 100), (4000, 1000).</code>

====Severity Decrease====
If the ambient temperature is less than the maximum comfortable temperature, the amount the severity will decrease every 60-tick interval is given by:
:<code>Decrease in heatstroke severity every 60 ticks = max(0.0015, min(0.015, 0.027×heatstroke_severity))</code>
This means that as long as the ambient temperature is less than the maximum comfortable temperature, heatstroke recovery is independent of temperature, but severity decreases at its fastest when it is above 50%, and at its slowest below 5.6%. Full recovery from near-100% severity occurs after 151 real-time seconds, or 3.6 in-game hours.

=== Hypothermia ===
Hypothermia occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) below their [[minimum comfortable temperature]]. [[Insectoids]] don't experience hypothermia, but instead get [[hypothermic slowdown]].

Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Hypothermic slowdown ===
{{quote|A special biological state used by some creatures to survive extreme cold. Instead of trying to stay warm, the creature's body chemistry adapts to prevent internal freezing despite very low temperature. Bodily functions are slowed and capacities are reduced, but the cold does no permanent damage. Some biologists call it a wakeful form of hibernation.}}

[[Insectoids]] avoid hypothermia and experience hypothermic slowdown instead with similar penalties but avoiding death at 100% and no [[frostbite]].

Slowdown value increases many times above 100% with apparently no upper limit. When defrosting insects this total value is used so defrost time is proportional to total time frozen.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Vacuum exposure ===
{{Odyssey|section=1}}
Vacuum exposure occurs when a pawn is subjected to [[Orbit|hard vacuum]] without adequate protection.

The rate of severity growth is directly proportional to the vacuum percentage of the pawn's current tile, and to the difference between 1 and a pawn's [[vacuum resistance]] stat. Vacuum will be 100% outside pressurized rooms; otherwise, it will vary depending on the presence of [[oxygen pump]]s, open connections to other rooms, and so on. The specific algorithm is:
# Start with a default of 2% per second.
# Multiply the amount by the tile's current vacuum percentage.
# Multiply the product by the difference between 1 and the pawn's vacuum resistance.
Expressed as a formula, the increase of severity every {{ticks|60}} is:
:<code>Increase in vacuum exposure severity = 0.02 * tile vacuum percentage * (1 - vacuum resistance)</code>

Vacuum exposure builds up extremely quickly in pawns without significant vacuum resistance. An unprotected pawn with no resistance will die in just {{ticks|3000}} of exposure to a complete vacuum, making even brief spacewalks a risky prospect.

Pawns recover quickly from vacuum exposure while inside a pressurized area; severity will simply fall at a flat 10% per second until the condition disappears entirely. Affected pawns that reach 100% vacuum resistance while still exposed (such as by equipping a [[vacsuit]]) will keep their current level of exposure until they return to a pressurized tile, but its severity will not increase any further.

== Pregnancy ==
{{See also|Animals#Mating{{!}}Mating|Animals#Breeding{{!}}Breeding|Reproduction{{!}}Human pregnancy}}
{{quote|This creature is gestating offspring. It will give birth if the pregnancy comes to term. If starved or injured, there may be a miscarriage.|Description}}

Tamed, non-[[human]], non-[[insectoid]], non-[[egg]]laying, female [[animals]] have a 50% chance to get pregnant from [[Animals#Mating|mating]]. While this is not an ailment in the traditional sense, it does have mechanical effects. For the first {{ticks|600}} this condition will be invisible, after which point a message will come up mentioning the pregnancy.

Humans can be pregnant only if the [[Biotech DLC]]{{BiotechIcon}} is enabled. They have a different list of symptoms. See [[Reproduction]] for details.

A pregnant animal suffering from [[malnutrition]] of 25% or higher or that is injured may miscarry. Miscarriages are noted by an in-game message.

Some animals will give birth to multiple young. The probability of this is determined by a curve, and is different for each animal.

The duration, and thus the severity gain per day, depends on the gestation time of the animal in question.

=== Sterilized ===
{{Stub|section=1|reason=Missing details, sources, mechanics etc. Are there any other causes in humans?}}
{{Quote|This creature's reproductive system has been permanently shut down.|Description}}
[[Animals]] can be sterilized by use of the "Sterilize" [[operation]] to prevent them from being able to reproduce, and the sterilized animal won't attempt to mate with others nor will others attempt to mate with it. [[Egg]] laying animals will stop laying eggs when sterilized. The animal acts as normal in all other ways, including [[milk]] production.

Sterilizing a pregnant animal will not terminate the pregnancy.

The sterilization operation requires [[Medical]] skill of 3 and {{ticks|500}} of work.

Humans with the "Sterilized" health trait can only be healed with a [[healer mech serum]]. Pawns can{{Check Tag|Will?|Is it all failures or just a chance?}} receive the sterilized ailment from a failed vasectomy or IUD insertion.{{BiotechIcon}} It is currently unknown if there are other sources.

== Drug damage ==
These ailments are caused by excess drug use.

=== Cirrhosis ===
A degenerative [[liver]] disease caused by excessive [[alcohol]] consumption.
An otherwise healthy pawn with cirrhosis will have an [[immunity gain speed]] of 70%, making them extremely vulnerable to disease.

Treatment:
* The easiest method of treatment is the [[Organ harvesting|transplantation]] of a new liver. Due to the extreme vulnerability to disease, even if your colony dislikes organ harvesting it may be worth it to replace the livers of valuable pawns as doctors will struggle to get high enough tend qualities on diseases to counterbalance the decreased immunity gain, often needing a very good hospital plus a very good doctor or [[glitterworld medicine]] to do so.
* Other than transplantation, only [[healer mech serum]] and [[unnatural healing]]{{AnomalyIcon}} can cure cirrhosis.

Alcohol [[tolerance]] above '''45%''' imposes a chance to get [[cirrhosis]] in the liver proportional to the tolerance held.

|}

The chance to receive trauma savant on any physical (non-chemical) [[injury]] to the brain is equal to the percentage of the brain damaged multiplied by 0.12. For an adult human, this represents 1.2% chance per point of damage. Animals can also become trauma savants.

A [[Ghoul|Ghoul]]{{AnomalyIcon}} or a humans with the [[Scarless]]{{BiotechIcon}} gene will not get brain scars from damage to their brain, but they still have a chance to become trauma savants. This makes it possible to voluntarily give the condition to a pawn by repeatedly damaging and healing their brain, although this can be time consuming and expensive. For an adult human, the brain will need to take on average 83 points of damage. Using other methods to heal the brain such as the [[Biosculpter pod#Bioregeneration|Bioregeneration cycle]] of the [[biosculpter pod]]{{IdeologyIcon}} is theoretically possible, but prohibitively expensive.

Currently, the most cost-effective known method to damage the brain is to purposefully fail the surgery to remove a [[Painstopper|painstopper]]. Painstoppers are the cheapest brain implant that can be removed. Attempting to remove it costs only one [[herbal medicine]] and failing will not destroy the implant. Performing the operation outside, on a [[Sleeping spot]] or an [[Ancient bed]],{{IdeologyIcon}} in the dark, with a low level surgeon with lowered Sight and Manipulation will maximize the chance for the operation to fail. If the operation accidentally succeeds, then the patient should be moved to a high quality hospital to reinsert the painstopper, as failure would destroy the implant and greatly increase the overall cost. It takes on average between 50 and 100 failed brain operations for a patient to become trauma savant.

Trauma savant negates the [[consciousness]] penalty from all brain damage, including scars that existed before the condition. On another hand, those brain scars will still lower the brain's health and can potentially still cause pain. Also, Trauma savant will not prevent loss of consciousness from other brain conditions like Dementia.

Trauma savant can be healed with a [[healer mech serum]] or the [[Unnatural healing]]{{AnomalyIcon}} ability (or possibly through other means as well). It can also be treated by killing the pawn, [[Skull|removing their skull]]{{IdeologyIcon}} then resurrecting thanks to a [[Resurrector mech serum]] or [[death refusal]]{{AnomalyIcon}}.

==Bliss lobotomy==
{{Anomaly|section = 1}}
{{Main|Bliss lobotomy}}
A whole-body condition that gives a constant +20 mood bonus but imposes a -50% global learning factor penalty. Makes pawn incapable of cooking, construction, plant work, mining, crafting and intellectual. Can generate on [[horax cult|cultist]] raiders or be deliberately induced via a brain surgery at the cost of 2 medicine and 30 [[bioferrite|bioferrites]].

== General ==
These ailments appear in gameplay, and usually wear off on their own (except death-causing ones).

=== Cryptosleep sickness ===
After-effects of using a cryptosleep pod. Cryptosleep suspends and replaces many bodily functions in order to prevent aging and death. Upon exiting cryptosleep, the body takes time to restart and rebalance its natural metabolic processes. While this is ongoing, the patient suffers from nausea, dizziness, and a sense of fuzziness in the mind.

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists in the "[[Crashlanded]]" scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

|}
Treatment:
* Wears off after {{ticks|10000}}

=== Food poisoning ===
Occurs after eating a contaminated meal or occasionally from raw food. The chance of contamination for cooked meals is primarily determined by the cook's [[food poison chance]] stat, with the [[Cleanliness|cleanliness of the room]] where it was prepared also being a potential factor.

[[Corpse]]s have a flat chance of 5% to give food poisoning. Other raw food has a flat chance in between 1% and 4% depending on the type of food — most raw food having a 2% chance. Cooked meals roll two separate probabilities to determine if the food is poisoned. The first checks the [[cleanliness]] of the kitchen used. See the accompanying graph for specifics. Note that cleanliness above -2 prevents this roll from producing poisoned meals. If the cooking station is outdoors, the default chance is 2%.

If the first roll fails to poison the meal, then a second roll is performed, this time based on the [[food poison chance]] of the pawn, controlled entirely by their [[Cooking|cooking skill]].
If the second roll indicates that the meal is poisonous, the probability of poisoning the pawn is 100% for that individual meal. However, when the poisonous meal is part of a stack with other meals, the probability is distributed among all the meals in the stack. This distribution reduces the chance of food poisoning from 100% to the ratio of total meals to poisonous meals within the stack. For instance, if a poisonous meal is placed on top of a stack containing three non-poisonous meals, the probability for each meal to poison the pawn becomes 25%. Consequently, even if the original meal was poisonous, there is a possibility that no pawns will experience food poisoning.

Because of the penalty to [[blood filtration]] and [[consciousness]], food poisoning in combination with other ailments such as an [[infection]] can be a cause for concern.

; Symptoms and progress:
Food poisoning lasts 24 hours with no after-effects. It has 3 stages: the first unpleasant 4 hours, followed by a crippling 16 hours, and finally an unpleasant 4 hours largely similar to the first stage, as described in the table below.

|}
; Treatment and Prevention
Food poisoning can only be minimized by manipulating the factors that cause it mentioned above. Prevention can only be guaranteed by exclusively consuming meals purchased from traders or by making [[Baby food]] or [[nutrient paste meal]]s as they will never cause food poisoning. Installing a [[sterilizing stomach|sterilizing]] {{RoyaltyIcon}}, [[nuclear stomach]] {{RoyaltyIcon}} or [[fleshmass stomach]] {{AnomalyIcon}}, or having the [[strong stomach]] gene{{BiotechIcon}} render pawns immune to contracting food poisoning. Note that [[bionic stomach]]s reduce the chance of getting food poisoning by 50% but cannot outright prevent it.

The notification for a colonist being poisoned will explain the cause of the poisoning. This can be very helpful if an unattended kitchen was allowed to cross into the very dirty -2 cleanliness danger zone, as a nearby cleaner can simply be ordered to clean the kitchen and avoid more unnecessary poisoning.

There is no practical treatment for food poisoning, you simply have to let it run its course. [[Healer mech serum]] will cure it (if there is nothing worse to cure), but this costly measure is rarely if ever worthwhile, as food poisoning only affects the pawn for the 24 hour cycle and then leaves them as healthy as they were before. [[Unnatural healing]]{{AnomalyIcon}} is the vastly more economical option, though it carries opportunity cost of the 6 day cooldown.

Because of the high chance of [[vomiting]] at any moment, putting the patient on a temporary diet of [[pemmican]] may be useful. Vomiting interrupts the process of eating, resetting it to the start, but a colonist can more quickly consume several pieces of pemmican between "attacks" that they can eat an entire [[meal]]. This allows the poisoned pawn to more easily avoid malnutrition without feeding them [[raw food]]s that could cause further poisoning.

=== Toxic buildup ===
{{Stub|section=1|reason=What is the effect of Toxic Environment Resistance vs Toxic Resistance, tox rain}}
Primarily occurs with exposure to [[toxic fallout]], [[pollution]],{{BiotechIcon}} and [[tox gas]].{{BiotechIcon}}. Prolonged exposure gradually increases the buildup severity.

Alternatively, some attacks cause instantaneous increases in toxic buildup severity, such as [[cobra]] and [[waste rat]] {{BiotechIcon}} bites, the [[venom talon]] {{RoyaltyIcon}}, or [[venom fangs]] {{RoyaltyIcon}}.

A colonist under a roof is protected from toxic fallout, and avoiding interaction with the other sources can prevent buildup from them. If they are exposed to the fallout, they will accumulate Toxic Buildup at a rate of 40% per day. Pollution will accumulate at the same rate, but cannot be mitigated through roofing. When walking through polluted terrain in [[caravan]]s, they will accumulate buildup at 20% per day in Moderately Polluted terrain (50%-75% polluted tiles) and 40% per day in Extremely Polluted terrain (above 75%). Buildup from both pollution as well as toxic fallout can stack, meaning a pawn standing in polluted terrain while a toxic fallout can gain 80%/day.

This buildup severity gained is proportional to the [[Toxic Resistance]] [[stat]] - thus, [[human]]s buildup at the full rate, [[animal]]s at half, and [[insects]] and [[mechanoids]] are immune.{{Check Tag|Body Size?|Buildup severities from Damage types are now inversely proportional to body size, are all sources scaled? Either way, add detail}} Buildup can also be reduced through a variety of of other means including items such as the [[gas mask]] {{BiotechIcon}}, [[detoxifier kidney]] {{BiotechIcon}}, and [[detoxifier lung]] {{BiotechIcon}}, as well as [[genes]]{{BiotechIcon}} such as [[Partial antitoxic lungs]]{{BiotechIcon}} and [[Total antitoxic lungs]],{{BiotechIcon}} or [[Tox resistance]]{{BiotechIcon}} and [[Tox immunity]].{{BiotechIcon}}

There is, effectively, a multiplier for each pawn on their toxic buildup accumulation from these indirect sources. This can vary between 15% faster buildup or 15% slower buildup than the average rate. There is no stat in the information panel to convey this variation, but it is static for a given pawn. This means that baseliner humans standing in pollution and a toxic fallout, with no Tox Resistance of any sort, can vary from either 68% to 92% buildup per day, rather than a constant 80%.

The buildup severity occurs in stages. The later stages cause permanent [[#Dementia|dementia]] which does not wear off even after toxic buildup subsides. When a pawn affected by toxic buildup [[Death|dies]], there is a chance that its corpse will instantly rot - this chance is equal to the severity.

Once a colonist returns to a safe area, such as a roofed area for toxic fallout, or otherwise stops taking severity increases, their buildup severity will gradually decrease. Once no longer exposed, severity reduces by 8% per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach high stages of toxic buildup are likely to develop further complications.

{{Biotech|section=1}}
{{quote|"This person was in a growth vat which wasn't functioning properly due to lack of power or nutrition feedstock. This has left their body in a state of bio-starvation."|In-game description}}
A pawn in a [[growth vat]] with no power or nutrition, will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. These include:
* [[Pain]]: {{++|15%}}
* [[Hunger Rate Factor]] offset: {{++|50%}}
* [[Consciousness]]: {{--|25%}}

=== Vomiting ===
{{Stub|section=1|reason=what does it interrupt, what happens when different tasks are underway - e.g. eating cancels the eating task but doesn't waste the meal, explanation that vomiting is expressed as mtb etc}}
The body attempting to forcefully expunge toxins. Unfortunately for your pawns, this doesn't work in Rimworld.

Vomiting is caused by a wide variety of ailments{{Check Tag|List Needed?}}, some [[Psycasts]]{{RoyaltyIcon}}, or being hit with an EMP while having the [[Sterilizing stomach|Sterilizing]], [[Reprocessor stomach|Reprocessor]], or [[Nuclear stomach|Nuclear]] stomachs{{RoyaltyIcon}} installed.

A pawn that is vomiting will stop in place, face the side, and begin vomiting. Vomiting lasts a random duration from {{Ticks|300}} to {{Ticks|900}}, and every 150 interval ticks it reduces the pawn's food bar by 0.04 and generates 1 stack of [[vomit]] filth on the tile they're facing. Note that this interval tick occurs independently from the beginning of the vomiting duration, and as such the number of times it occurs may not be the simple division of the chose duration divided by 150. As such, between one fewer and one more interval may occur than the the division would indicate. A pawn lying in a bed will not stand up to vomit{{Check Tag|Details|Does this pause the resting bonus from lying down? Does it wake them up?}}.

Vomiting will interrupt most tasks, including eating, walking, aiming a weapon, or working at a station, but they will resume the task once they stop vomiting{{Check Tag|Mechanics|Do pawns who are actively vomiting still reserve the task they were working on?}}. For this reason, it is recommended that pawns who are afflicted with an ailment that causes frequent vomiting, such as [[food poisoning]], eat foods like [[pemmican]], as a pawn who vomits while in the middle of eating a normal meal will lose all progress towards consuming it (note that the meal is not wasted), but a pawn eating pemmican will still consume part of the stack. Similarly, they should also avoid long tasks that have their progress reset on being interrupted, such as cooking 4x [[lavish meal]]s.

=== Crumbling mind ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}

The gradual breakdown of the mind. While technically non-fatal, it applies mounting consciousness penalties, and its final stage renders a pawn incapable of nearly all work.

Crumbling mind is caused by two [[Anomaly]] events - The [[Corrupted obelisk]] and the [[Creepjoiner]]. It cannot affect pawns that existed before those events, only ones created by them. It can be detected before ailments show by a surgical inspection.

Creepjoiners with this condition will begin showing symptoms within 2-3.33 days. Duplicated pawns will begin showing them within 12-48 hours. Severity progresses by 33% per day. Progress can be paused through the use of a [[cryptosleep casket]].

Crumbling mind can be cured by a [[healer mech serum]] as well as the [[unnatural healing]] ability so long as it hasn't progressed to the final stage of '''Crumbled mind'''. Once it has, the condition is incurable, short of destroying the colonists brain then resurrecting them with either a [[resurrector mech serum]] or [[death refusal]]. However, consistently destroying the brain can be difficult. There are 5 main ways to archive it:
* With the [[Biotech DLC]], using a [[Subcore ripscanner]] on the colonist in question will kill it by destroying its brain.
* Also with the Biotech DLC, extracting the pawn's genes with a [[Gene extractor]] while the '''Genes Regrowing''' Hefiff remains active will kill it by brain destruction.
* With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will destroy its head reliably and safely.
* Fatal [[Luciferium]] withdraw kills by destroying the brain.
* Allow colonists or animals to eat sections of the corpse, risking consuming the entire body before the head is removed.

Furthermore, no matter how successful the head removal, the costs and downsides of the either the serum or refusal remain. If this strategy is used, remember not to euthanize them or they will be no longer of your faction after resurrection.

Counterintuitively, [[Ghoul|ghoul infusion]] will not cure crumbling mind and it will hinder ghoul's combat abilities.

=== Duplicate sickness ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}
Psychic interference between this person and their duplicate is causing slow mental deterioration. As long as multiple copies of this person are alive, the condition will keep getting worse. However, the condition will not be lethal.

Duplicate sickness is one of the potential outcomes from the duplication of a pawn by a [[corrupted obelisk]]. It affects both the original pawn and the duplicate{{Check Tag|Wb other duplicates?|Test both a previous duplicate (i.e. use obelisk gizmo, wait cooldown use again) and mass cloning (i.e. when 30 pawns spawn when it reaches max activity}} and is initially hidden. Severity increases by 10% per day that both pawns are alive{{Check Tag|Wb in crypto?|Does severity increase if the pawn is in cryptosleep? If no, does it pause on both or just the one in crypto? If no, wb if both are in crypto?}} and gradually reduces the consciousness of both pawns and makes them more likely to have [[mental breaks]], before eventually rendering both comatose.

It cannot be treated,{{Check Tag|Verify}} but can be cured by one of three methods: [[healer mech serum]], the [[unnatural healing]] ability, or the death of one of the two pawns.

If one of the two connected pawns is killed, the other's duplication sickness severity immediately starts regressing at the rate of 50% per day, while the killed pawn's duplication sickness is instantly cured. The killed pawn can then be immediately resurrected with a [[resurrector mech serum]] or [[death refusal]] without stopping the regression of the other pawn's sickness. Similarly, if one of the linked pawns is turned into a [[ghoul]], killed, and revived with a [[ghoul resurrection serum]], the same mechanics apply.

== Surgical ==
These ailments happen with medical operations.

=== Anesthetic ===
Used in surgery to make sure that a pawn is unconscious. It can also be administered outside of operations using a medical bill, consuming medicine.

A pawn under anesthesia is unconscious for the first 6 hours, and the worst effects of anesthetic wear off after 12 hours, so arranging operations to be performed some time just before a pawn needs to sleep is recommended if you want them functioning the next work day.

** Surgery is unaffected even if it wears off before finished

==== Version history ====
Prior to 1.1 it lasted only {{ticks|15000}} and did not have any other stages afterwards.

== Resurrection ==
These may occur after a dose of [[resurrector mech serum]] is applied on a [[Death|dead]] pawn.

=== Resurrection sickness ===
After-effects of being resurrected by mechanite injection. Artificially-kickstarted body processes take time to rebalance themselves.

{| class="wikitable"

'''Probability:'''
* 100% chance of being applied

=== Blindness ===
Mechanites fail to properly repair the eyes, instead causing more damage to it, resulting in blindness.

Blindness from [[resurrector mech serum]] applies to both eyes, resulting in total blindness

{| class="wikitable"

* Replace eyes with [[bionic eye]]s or [[archotech eye]]s

'''Probability:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

=== Resurrection psychosis ===
Chaotic thought patterns caused by the decoherence of resurrection mechanites. Resurrection psychosis progresses and eventually causes total psychosis and [[death]].

The severity of the psychosis increases by 0.01 per day, meaning that it will kill in 100 days after resurrection, or 90 days after this ailment becoming visible. Hopefully this gives you enough time to find a [[healer mech serum]] to heal the ailment, find another [[resurrector mech serum]] to attempt the resurrection again once the psychosis has run its course, or build a [[cryptosleep casket]] to give you time to find either serum. There are no other ways to cure the disease.

'''Treatments:'''
* Healer mech serum
* Allowing the pawn to [[Death|die]] again, then resurrecting once more (rerolls the disease)

'''Probability of contracting:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

'''Prevention:'''
* Freeze corpses immediately after death. Corpses placed in a [[sarcophagus]] are still affected by the temperature of the room they are in, and can be removed later but are protected from butchering, hungry animals and assuming you build the sarcophagus from something [[Flammability|non-flammable]], [[fire]].

== Heart attack ==
Heart attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in humans), triggered by the [[Events#Birthday|birthday event]]. There must be 2 or more colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days):
* 0-60% of life expectancy: 99,999,999 - 99,999,999
* 60-80% of life expectancy: 99,999,999 - 2,500
* 80-100% of life expectancy: 2,500 - 300

Examples of intervals and chances:
* 70% of life expectancy (i.e. 56 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
* 90% of life expectancy (i.e. 72 in humans): 1,400 days (approx. 0.000714% per day)

=== Stages ===

* [[Consciousness]] max. 10% (Unconsciousness)
* [[Pain]] +60%
|-
|'''Fatal''' || 100% Severity ||
* [[Death]]
|}

==== Progression ====
Heart attacks always start at 40% severity. Each interval the heart attack severity will randomly change by a value between {{---|40%}} to {{++|60%}}. This means that it is possible for a heart attack to recover on its own, but usually (~76% likelihood){{Check Tag|Detail needed|How is this calculated??}} an untreated heart attack progresses to fatal severity. The interval between changes is random, and varies between {{Ticks|500}} and {{Ticks|10000}}.

==== Treatment ====
Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by {{---|30%}}. Successfully reducing severity below 0% will completely treat the heart attack.

The chance a particular treatment can succeed is 65% multiplied by the [[tend quality]], for an effective maximum of 84.5% with [[glitterworld medicine]].

==== Prevention ====
Replacing a pawn's heart with either a [[prosthetic heart|prosthetic]] or [[bionic heart]] will completely prevent heart attacks. Note however that while the bionic heart improves the [[blood pumping]] capacity, the prosthetic heart decreases it, and thus all of the stats and capacities it affects.

* [[Version/1.3.3117|1.3.3117]] - Extreme blood loss now reduces consciousness by 40% in addition to setting the capacity's max to 10%. Prior to this, pawns could nonsensically [[Death|die]] by healing from extreme to severe bloodloss if their consciousness was below 40% from other symptoms - extreme would simply max it at 10% but healing to severe would reduce it by 40% to 0% and kill the pawn.
* [[Version/1.4.3523|1.4.3523]] - Sterilized animals no longer lay eggs.
* [[Version/1.6.4518|1.6.4518]] - Vacuum exposure implemented with [[Odyssey]].

'''Ailments''' are [[health]] conditions that cannot be treated completely using medicine alone.

"MTB" stands for "Mean Time Between", and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

Most permanent ailments are curable with body part replacements or usage of the [[healer mech serum]].

{{Heal Option Table}}

== Chronic ==
Ailments that come with age. Either non-fatal, or progresses extremely slowly towards fatality compared to infectious diseases.

=== Alzheimer's ===
{{stub|reason = "Forget memory" and "confused wandering" mechanics}}
A brain disease usually associated with aging. Alzheimer's disease causes progressive degradation in the ability to think and remember. Patients are known to forget close relatives and sometimes wander around in confusion.

Alzheimer's progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity from when it first appears.

'''Treatment:'''
* [[Luciferium]]: Luciferium removes one randomly selected condition that it can cure every 900,000 to 1,800,000 [[ticks]] (15 - 30 in-game days). Having fewer luciferium-curable conditions will increase the chance that Alzheimer's is chosen, so it can be worth attempting to address any conditions that can be other means. Even with this however, it can take a significant amount of time. Also note that luciferium is a permanent decision - once taken, further doses are necessary to avoid madness and death.
* [[Healer mech serum]]: A healer mech serum will instantaneously heal one condition of the pawn, including Alzheimer's. Which condition is chosen depends on a priority order, with Alzheimer's being a moderately high priority. See the serum's [[Healer mech serum#Summary|condition order]] for details.
* [[Resurrector mech serum]]: Because the resurrector mech serum will replace a destroyed head with a healthy one, it can be used to heal brain ailments, including Alzheimers. Consistently destroying the head can be difficult. With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will do this reliably and safely, but without it, the best way is allowing colonists or animals to eat sections of the corpse, at the risk of consuming the entire body and permanently losing the pawn. Furthermore, no matter how successful the head removal, there is always the risks normally associated with resurrection, including [[dementia]], [[blindness]], and [[resurrection psychosis]]. Note that pawns will initially be incapacitated due to resurrection sickness.
* [[Death refusal]]{{AnomalyIcon}}: Similar to the [[Resurrector mech serum]], a pawn imbued with death refusal can self-resurrect and replace a destroyed head with a healthy one. This comes with the drawback of the pawn losing experience in their skills that happens upon imbuing the death refusal. Pawns resurrected via this method will also have resurrection sickness and a negative [[Mood|moodlet]] upon being resurrected.
* [[Chronophagy]]{{AnomalyIcon}}: As pawns younger than 34 cannot get Alzheimer's, reversing age to younger than that in a Chronophagy ritual will remove it.
* [[Unnatural healing]]{{AnomalyIcon}}: a Creepjoiner with unnatural healing replicates the effect of a healer mech serum and so can be similarly used to cure Alzheimers at the minor risk of replacing an arm with a flesh tentacle for the cured pawn

=== Asthma ===
A chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. Unlike other chronic diseases, asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line.

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity (50%).

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% beginning to regress the stages of asthma (the higher, the better).

{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms

|-
| '''Asthma (major)''' || ≥ 30% severity || -30% part efficiency
|-
| '''Asthma (major)''' || ≥ 45% severity || -50% part efficiency
|}

Treatment:
* The severity of asthma can be reduced with treatment, which can be given every 420,000 ticks (around 7 days). One treatment applies to both lungs.
* Asthma can be cured by replacing each affected lung with a [[Lung#Acquisition|healthy replacement]].

A human pawn can first get asthma at any age.

Asthma can also affect animals, domestic, tamed and wild. Domestic and tamed will notify you that they "need treatment", although there apparently is no downside for ignoring that request except slowing them down which may be bad for [[Animals#Training|trained]] or [[pack animal]]s. Similarly, asthmatic wild animals on the map can roam and eat indefinitely without treatment. In fact, wild animals with asthma are easier and slightly safer to hunt, because asthma will reduce their [[move speed]] to 81%, and their [[manipulation]] to only 90%, which makes any counter-attack less effective.

=== Bad back ===

=== Carcinoma ===
{{Stub|section=1|reason=How do the stages progress/occur and what chances and factors affects them?}}
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumors, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed by a skilled doctor or, in some cases, the affected body part can be removed, either by amputation, transplantation of a healthy body part, or replacement by an [[artificial body part]]. Ordinary treatment will prolong the development of a carcinoma or speed up remission, and can be done by doctors of any skill, though better treatment quality is more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.
* When growing, it progresses by 0.003 per day, multiplied by a random factor of 0.45 - 1.65.
* When stable, it neither grows nor regresses on its own.
* When in remission, it regresses by 0.002 per day, multiplied by a random factor of 0.7 - 1.5.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will:
* grow more slowly when in growing stage
:* some slow-growing carcinomas (something less than half) may stop or actually regress (very slowly) during their "growing" stage with good treatment
* slowly regress when stable
* regress quickly when in remission

Treatment:
* Treated every {{ticks|240000}}
* The carcinoma will disappear if severity reaches 0.
* "Excise carcinoma" surgery; this needs 4 medicine of [[medicine|industrial quality]] or above, {{ticks|4500}} of work, and a doctor with a [[medical]] skill of 10 or above. The surgery has a 100% base chance to succeed. If it fails, there is a 25% chance that the patient [[Death|dies]]. Thus, as the maximum [[Doctoring#Success chance|success chance]] is capped at 98%, there is always at least a 0.5% chance of death per attempt.

A human pawn must be at least 22.4 years old to get carcinoma from aging, meaning it can first occur at their 23rd birthday. Carcinomas from other sources, including [[toxic buildup]] and [[nuclear stomach]]s{{RoyaltyIcon}}, can happen at any age. Installed nuclear stomachs create a carcinoma on the torso with an MTB of 120 days.

=== Artery blockage ===
A blockage in one of the critical arteries in the [[heart]]. Heart artery blockages randomly induce [[#Heart attack|heart attacks]]. Artery blockages can be treated by replacing the heart with a [[heart|natural]], [[prosthetic heart|prosthetic]] or [[bionic heart|bionic]] replacement, with a [[healer mech serum]], with [[luciferium]], or with the use of [[biosculpter pod]]'s bioregeneration cycle{{IdeologyIcon}}.

Artery blockages progress by a base of 0.0007 per day, multiplied by a random factor between 0.5 - 3.
This means that artery blockages can take anywhere from 7.9 to 47.6 in-game years from onset to become fatal on its own.

Artery blockages can be treated by replacing the heart.

== Acute ==
Some ailments arise as a result of an acute lack of food or exposure to extreme temperatures. These ailments can only be treated by addressing the underlying cause (e.g. providing food or moving to more comfortable temperatures).

=== Malnutrition ===
When a pawn's [[Eating|food]] meter reaches 0%, they will begin to suffer from [[malnutrition]], shown on the health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

Malnutrition severity without food will advance at an average of 17% per day. There is a variation for each pawn that will vary this by 20% in both directions, meaning a pawn may actually die of malnutrition between 4.9~7.4 days of first having symptoms. There is no stat indicating the specific rate that a pawn may die of malnutrition, but the modified rate is determined for each specific pawn in a given playthrough.

|}



=== Blood loss ===
{{About|section=1|the effect of already lost blood|the mechanics that cause blood loss|Bleeding}}
A reduction in the normal blood volume. Minor blood loss has relatively mild effects, but as severity increases, the [[consciousness]] rapidly become debilitating. Extreme blood loss leads to [[death]]. Total blood loss is listed under whole body, with a tooltip showing the percent.

Blood loss can occur when a pawn has untreated [[Injury#Bleeding|bleeding injuries]], has had blood harvested for [[hemogen pack]]s,{{BiotechIcon}} or has been fed on by a [[Bloodfeeder]].{{BiotechIcon}} Blood loss from multiple sources stacks additively.

All pawns recover 33.3% of their blood per day, regardless of [[traits]], [[genes]], [[drugs]], or [[artificial body parts]]. All natural blood recovery is stopped when a pawn is [[bleeding]], even in small amounts. Pawns can also recover through a blood transfusion operation, using 1 [[hemogen pack]]{{BiotechIcon}} to recover 35%. The [[Biosculpter_pod#Medic|biosculpter pod's medic cycle]]{{IdeologyIcon}} will also cure all blood loss, though it should be noted that non-transhumanist pawns would recover completely from blood loss in the same time as the cycle takes to complete anyway. If there is no other reason to use the medic cycle, non-transhumanist pawns should just recover outside of the pod and remain productive for that time.

=== Heatstroke ===
Heat stroke occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) above their [[maximum comfortable temperature]], and recovery occurs in temperatures less than the maximum comfortable temperature.
Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.

Pawns additionally take periodic burn damage in temperatures more than 150°C (270°F) above their maximum comfortable temperature.
====Severity Increase====

The procedure for determining severity growth every 60-tick interval is given by:
# Take the amount by which the ambient temperature exceeds the pawn's maximum safe temperature (which is the maximum comfortable temperature +10°C).
# Pass the amount through the curve shown below to obtain the effective temperature excess. Note that for amounts from 0 to 25 °C, this doesn't result in a change.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval (60 ticks, 1 second).
# If the growth is less than <code>0.000375</code>, set it to that number. This sets a minimum amount the severity increases by for temperatures in the range of 10 to 15.814°C above the maximum comfortable temperature.
:<code>Increase in heatstroke severity every 60 ticks = max(0.000375, 0.0000645×effective_temperature_curve(<i>ambient_temperature</i> - (<i>maximum_comfortable_temperature</i> + 10°C)))</code>
::<code><i>where </i>effective_temperature_curve()<i> is a post-processing curve with points</i>: (0, 0), (25, 25), (50, 40), (100, 60), (200, 80), (400, 100), (4000, 1000).</code>

====Severity Decrease====
If the ambient temperature is less than the maximum comfortable temperature, the amount the severity will decrease every 60-tick interval is given by:
:<code>Decrease in heatstroke severity every 60 ticks = max(0.0015, min(0.015, 0.027×heatstroke_severity))</code>
This means that as long as the ambient temperature is less than the maximum comfortable temperature, heatstroke recovery is independent of temperature, but severity decreases at its fastest when it is above 50%, and at its slowest below 5.6%. Full recovery from near-100% severity occurs after 151 real-time seconds, or 3.6 in-game hours.

=== Hypothermia ===
Hypothermia occurs when a pawn has prolonged exposure to [[temperature]]s 10°C (18°F) below their [[minimum comfortable temperature]]. [[Insectoids]] don't experience hypothermia, but instead get [[hypothermic slowdown]].

Note that it is possible for a pawn to have both heatstroke and hypothermia at the same time if time is spent in both extreme heat and cold - their severities are unrelated.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.
Expressed as a formula, this is:
:<code>Increase in hypothermia severity every 60 ticks = max(0.00075, (<i>degrees_below_comfortable</i> - 10)*0.0000645)</code>

=== Hypothermic slowdown ===
{{quote|A special biological state used by some creatures to survive extreme cold. Instead of trying to stay warm, the creature's body chemistry adapts to prevent internal freezing despite very low temperature. Bodily functions are slowed and capacities are reduced, but the cold does no permanent damage. Some biologists call it a wakeful form of hibernation.}}

[[Insectoids]] avoid hypothermia and experience hypothermic slowdown instead with similar penalties but avoiding death at 100% and no [[frostbite]].

Slowdown value increases many times above 100% with apparently no upper limit. When defrosting insects this total value is used so defrost time is proportional to total time frozen.


The rate of severity growth depends on the difference below the pawn's minimum safe temperature and the ambient temperature. The specific algorithm is:
# Take the amount by which the pawn's minimum safe temperature (which is the [[minimum comfortable temperature]] -10°C) exceeds the ambient temperature.
# Multiply the excess by <code>6.45e-5</code> to obtain the severity growth this interval. Note that unlike hyperthermia, hypothermia calculations don't use a postprocessing curve.
# If the growth is less than <code>0.00075</code>, set it to that number. As a result, temperatures between 10°C and 21.63°C less than the minimum comfortable temperature all have the same severity growth.

=== Vacuum exposure ===
{{Odyssey|section=1}}
Vacuum exposure occurs when a pawn is subjected to [[Orbit|hard vacuum]] without adequate protection.

The rate of severity growth is directly proportional to the vacuum percentage of the pawn's current tile, and to the difference between 1 and a pawn's [[vacuum resistance]] stat. Vacuum will be 100% outside pressurized rooms; otherwise, it will vary depending on the presence of [[oxygen pump]]s, open connections to other rooms, and so on. The specific algorithm is:
# Start with a default of 2% per second.
# Multiply the amount by the tile's current vacuum percentage.
# Multiply the product by the difference between 1 and the pawn's vacuum resistance.
Expressed as a formula, the increase of severity every {{ticks|60}} is:
:<code>Increase in vacuum exposure severity = 0.02 * tile vacuum percentage * (1 - vacuum resistance)</code>

Vacuum exposure builds up extremely quickly in pawns without significant vacuum resistance. An unprotected pawn with no resistance will die in just {{ticks|3000}} of exposure to a complete vacuum, making even brief spacewalks a risky prospect.

Pawns recover quickly from vacuum exposure while inside a pressurized area; severity will simply fall at a flat 10% per second until the condition disappears entirely. Affected pawns that reach 100% vacuum resistance while still exposed (such as by equipping a [[vacsuit]]) will keep their current level of exposure until they return to a pressurized tile, but its severity will not increase any further.

{{quote|This creature is gestating offspring. It will give birth if the pregnancy comes to term. If starved or injured, there may be a miscarriage.|Description}}

Tamed, non-[[human]], non-[[insectoid]], non-[[egg]]laying, female [[animals]] have a 50% chance to get pregnant from [[Animals#Mating|mating]]. While this is not an ailment in the traditional sense, it does have mechanical effects. For the first {{ticks|600}} this condition will be invisible, after which point a message will come up mentioning the pregnancy.

Humans can be pregnant only if the [[Biotech DLC]]{{BiotechIcon}} is enabled. They have a different list of symptoms. See [[Reproduction]] for details.

A pregnant animal suffering from [[malnutrition]] of 25% or higher or that is injured may miscarry. Miscarriages are noted by an in-game message.

Some animals will give birth to multiple young. The probability of this is determined by a curve, and is different for each animal.

The duration, and thus the severity gain per day, depends on the gestation time of the animal in question.

=== Sterilized ===
{{Stub|section=1|reason=Missing details, sources, mechanics etc. Are there any other causes in humans?}}
{{Quote|This creature's reproductive system has been permanently shut down.|Description}}
[[Animals]] can be sterilized by use of the "Sterilize" [[operation]] to prevent them from being able to reproduce, and the sterilized animal won't attempt to mate with others nor will others attempt to mate with it. [[Egg]] laying animals will stop laying eggs when sterilized. The animal acts as normal in all other ways, including [[milk]] production.

Sterilizing a pregnant animal will not terminate the pregnancy.

The sterilization operation requires [[Medical]] skill of 3 and {{ticks|500}} of work.

Humans with the "Sterilized" health trait can only be healed with a [[healer mech serum]]. Pawns can{{Check Tag|Will?|Is it all failures or just a chance?}} receive the sterilized ailment from a failed vasectomy or IUD insertion.{{BiotechIcon}} It is currently unknown if there are other sources.

== Drug damage ==
These ailments are caused by excess drug use.

=== Cirrhosis ===
A degenerative [[liver]] disease caused by excessive [[alcohol]] consumption.
An otherwise healthy pawn with cirrhosis will have an [[immunity gain speed]] of 70%, making them extremely vulnerable to disease.

Treatment:

Due to the extreme vulnerability to disease, even if your colony dislikes organ harvesting it may be worth it to replace the livers of valuable pawns as doctors will struggle to get high enough tend qualities on diseases to counterbalance the decreased immunity gain, often needing a very good hospital plus a very good doctor or [[glitterworld medicine]] to do so.
* Other than transplantation, only [[healer mech serum]] and [[unnatural healing]]{{AnomalyIcon}} can cure cirrhosis.

|}

The chance to receive trauma savant on any physical (non-chemical) [[injury]] to the brain is equal to the percentage of the brain damaged multiplied by 0.12. For an adult human, this represents 1.2% chance per point of damage. Animals can also become trauma savants.

A [[Ghoul|Ghoul]]{{AnomalyIcon}} or a humans with the [[Scarless]]{{BiotechIcon}} gene will not get brain scars from damage to their brain, but they still have a chance to become trauma savants. This makes it possible to voluntarily give the condition to a pawn by repeatedly damaging and healing their brain, although this can be time consuming and expensive. For an adult human, the brain will need to take on average 83 points of damage. Using other methods to heal the brain such as the [[Biosculpter pod#Bioregeneration|Bioregeneration cycle]] of the [[biosculpter pod]]{{IdeologyIcon}} is theoretically possible, but prohibitively expensive.

Currently, the most cost-effective known method to damage the brain is to purposefully fail the surgery to remove a [[Painstopper|painstopper]]. Painstoppers are the cheapest brain implant that can be removed. Attempting to remove it costs only one [[herbal medicine]] and failing will not destroy the implant. Performing the operation outside, on a [[Sleeping spot]] or an [[Ancient bed]],{{IdeologyIcon}} in the dark, with a low level surgeon with lowered Sight and Manipulation will maximize the chance for the operation to fail. If the operation accidentally succeeds, then the patient should be moved to a high quality hospital to reinsert the painstopper, as failure would destroy the implant and greatly increase the overall cost. It takes on average between 50 and 100 failed brain operations for a patient to become trauma savant.

Trauma savant negates the [[consciousness]] penalty from all brain damage, including scars that existed before the condition. On another hand, those brain scars will still lower the brain's health and can potentially still cause pain. Also, Trauma savant will not prevent loss of consciousness from other brain conditions like Dementia.

Trauma savant can be healed with a [[healer mech serum]] or the [[Unnatural healing]]{{AnomalyIcon}} ability (or possibly through other means as well). It can also be treated by killing the pawn, [[Skull|removing their skull]]{{IdeologyIcon}} then resurrecting thanks to a [[Resurrector mech serum]] or [[death refusal]]{{AnomalyIcon}}.

==Bliss lobotomy==
{{Anomaly|section = 1}}
{{Main|Bliss lobotomy}}
A whole-body condition that gives a constant +20 mood bonus but imposes a -50% global learning factor penalty. Makes pawn incapable of cooking, construction, plant work, mining, crafting and intellectual. Can generate on [[horax cult|cultist]] raiders or be deliberately induced via a brain surgery at the cost of 2 medicine and 30 [[bioferrite|bioferrites]].

== General ==
These ailments appear in gameplay, and usually wear off on their own (except death-causing ones).

=== Cryptosleep sickness ===
After-effects of using a cryptosleep pod. Cryptosleep suspends and replaces many bodily functions in order to prevent aging and death. Upon exiting cryptosleep, the body takes time to restart and rebalance its natural metabolic processes. While this is ongoing, the patient suffers from nausea, dizziness, and a sense of fuzziness in the mind.

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists in the "[[Crashlanded]]" scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

|}
Treatment:

=== Food poisoning ===
Occurs after eating a contaminated meal or occasionally from raw food. The chance of contamination for cooked meals is primarily determined by the cook's [[food poison chance]] stat, with the [[Cleanliness|cleanliness of the room]] where it was prepared also being a potential factor.

[[Corpse]]s have a flat chance of 5% to give food poisoning. Other raw food has a flat chance in between 1% and 4% depending on the type of food — most raw food having a 2% chance. Cooked meals roll two separate probabilities to determine if the food is poisoned. The first checks the [[cleanliness]] of the kitchen used. See the accompanying graph for specifics. Note that cleanliness above -2 prevents this roll from producing poisoned meals. If the cooking station is outdoors, the default chance is 2%.

If the first roll fails to poison the meal, then a second roll is performed, this time based on the [[food poison chance]] of the pawn, controlled entirely by their [[Cooking|cooking skill]].
If the second roll indicates that the meal is poisonous, the probability of poisoning the pawn is 100% for that individual meal. However, when the poisonous meal is part of a stack with other meals, the probability is distributed among all the meals in the stack. This distribution reduces the chance of food poisoning from 100% to the ratio of total meals to poisonous meals within the stack. For instance, if a poisonous meal is placed on top of a stack containing three non-poisonous meals, the probability for each meal to poison the pawn becomes 25%. Consequently, even if the original meal was poisonous, there is a possibility that no pawns will experience food poisoning.

Because of the penalty to [[blood filtration]] and [[consciousness]], food poisoning in combination with other ailments such as an [[infection]] can be a cause for concern.

; Symptoms and progress:
Food poisoning lasts 24 hours with no after-effects. It has 3 stages: the first unpleasant 4 hours, followed by a crippling 16 hours, and finally an unpleasant 4 hours largely similar to the first stage, as described in the table below.

|}
; Treatment and Prevention
Food poisoning can only be minimized by manipulating the factors that cause it mentioned above. Prevention can only be guaranteed by exclusively consuming meals purchased from traders or by making [[Baby food]] or [[nutrient paste meal]]s as they will never cause food poisoning. Installing a [[sterilizing stomach|sterilizing]] {{RoyaltyIcon}}, [[nuclear stomach]] {{RoyaltyIcon}} or [[fleshmass stomach]] {{AnomalyIcon}}, or having the [[strong stomach]] gene{{BiotechIcon}} render pawns immune to contracting food poisoning. Note that [[bionic stomach]]s reduce the chance of getting food poisoning by 50% but cannot outright prevent it.

The notification for a colonist being poisoned will explain the cause of the poisoning. This can be very helpful if an unattended kitchen was allowed to cross into the very dirty -2 cleanliness danger zone, as a nearby cleaner can simply be ordered to clean the kitchen and avoid more unnecessary poisoning.

There is no practical treatment for food poisoning, you simply have to let it run its course. [[Healer mech serum]] will cure it (if there is nothing worse to cure), but this costly measure is rarely if ever worthwhile, as food poisoning only affects the pawn for the 24 hour cycle and then leaves them as healthy as they were before. [[Unnatural healing]]{{AnomalyIcon}} is the vastly more economical option, though it carries opportunity cost of the 6 day cooldown.

Because of the high chance of [[vomiting]] at any moment, putting the patient on a temporary diet of [[pemmican]] may be useful. Vomiting interrupts the process of eating, resetting it to the start, but a colonist can more quickly consume several pieces of pemmican between "attacks" that they can eat an entire [[meal]]. This allows the poisoned pawn to more easily avoid malnutrition without feeding them [[raw food]]s that could cause further poisoning.

=== Toxic buildup ===
{{Stub|section=1|reason=What is the effect of Toxic Environment Resistance vs Toxic Resistance, tox rain}}
Primarily occurs with exposure to [[toxic fallout]], [[pollution]],{{BiotechIcon}} and [[tox gas]].{{BiotechIcon}}. Prolonged exposure gradually increases the buildup severity.

Alternatively, some attacks cause instantaneous increases in toxic buildup severity, such as [[cobra]] and [[waste rat]] {{BiotechIcon}} bites, the [[venom talon]] {{RoyaltyIcon}}, or [[venom fangs]] {{RoyaltyIcon}}.

A colonist under a roof is protected from toxic fallout, and avoiding interaction with the other sources can prevent buildup from them. If they are exposed to the fallout, they will accumulate Toxic Buildup at a rate of 40% per day. Pollution will accumulate at the same rate, but cannot be mitigated through roofing. When walking through polluted terrain in [[caravan]]s, they will accumulate buildup at 20% per day in Moderately Polluted terrain (50%-75% polluted tiles) and 40% per day in Extremely Polluted terrain (above 75%). Buildup from both pollution as well as toxic fallout can stack, meaning a pawn standing in polluted terrain while a toxic fallout can gain 80%/day.

This buildup severity gained is proportional to the [[Toxic Resistance]] [[stat]] - thus, [[human]]s buildup at the full rate, [[animal]]s at half, and [[insects]] and [[mechanoids]] are immune.{{Check Tag|Body Size?|Buildup severities from Damage types are now inversely proportional to body size, are all sources scaled? Either way, add detail}} Buildup can also be reduced through a variety of of other means including items such as the [[gas mask]] {{BiotechIcon}}, [[detoxifier kidney]] {{BiotechIcon}}, and [[detoxifier lung]] {{BiotechIcon}}, as well as [[genes]]{{BiotechIcon}} such as [[Partial antitoxic lungs]]{{BiotechIcon}} and [[Total antitoxic lungs]],{{BiotechIcon}} or [[Tox resistance]]{{BiotechIcon}} and [[Tox immunity]].{{BiotechIcon}}

There is, effectively, a multiplier for each pawn on their toxic buildup accumulation from these indirect sources. This can vary between 15% faster buildup or 15% slower buildup than the average rate. There is no stat in the information panel to convey this variation, but it is static for a given pawn. This means that baseliner humans standing in pollution and a toxic fallout, with no Tox Resistance of any sort, can vary from either 68% to 92% buildup per day, rather than a constant 80%.

The buildup severity occurs in stages. The later stages cause permanent [[#Dementia|dementia]] which does not wear off even after toxic buildup subsides. When a pawn affected by toxic buildup [[Death|dies]], there is a chance that its corpse will instantly rot - this chance is equal to the severity.

Once a colonist returns to a safe area, such as a roofed area for toxic fallout, or otherwise stops taking severity increases, their buildup severity will gradually decrease. Once no longer exposed, severity reduces by 8% per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach high stages of toxic buildup are likely to develop further complications.

=== Brain shock ===
{{quote|"After-effects of an electrical shock to the brain. This is generally cause by feedback from brain implants hit by EMP pulses." - '''In-game description'''}}
Occurs when an [[EMP]] effect hits a pawn with the following brain implants:
* [[Learning assistant]] {{RoyaltyIcon}}
* [[Neurocalculator]] {{RoyaltyIcon}}
* [[Circadian assistant]] {{RoyaltyIcon}}
* [[Circadian half-cycler]] {{RoyaltyIcon}}
* [[Pilot assistant]] {{OdysseyIcon}}
It lasts between {{ticks|2500}} and {{ticks|3500}}.

=== Bio-starvation ===
{{Biotech|section=1}}
{{quote|"This person was in a growth vat which wasn't functioning properly due to lack of power or nutrition feedstock. This has left their body in a state of bio-starvation."|In-game description}}
A pawn in a [[growth vat]] with no power or nutrition, will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. These include:
* [[Pain]]: {{++|15%}}
* [[Hunger Rate Factor]] offset: {{++|50%}}
* [[Consciousness]]: {{--|25%}}

=== Vomiting ===
{{Stub|section=1|reason=what does it interrupt, what happens when different tasks are underway - e.g. eating cancels the eating task but doesn't waste the meal, explanation that vomiting is expressed as mtb etc}}
The body attempting to forcefully expunge toxins. Unfortunately for your pawns, this doesn't work in Rimworld.

Vomiting is caused by a wide variety of ailments{{Check Tag|List Needed?}}, some [[Psycasts]]{{RoyaltyIcon}}, or being hit with an EMP while having the [[Sterilizing stomach|Sterilizing]], [[Reprocessor stomach|Reprocessor]], or [[Nuclear stomach|Nuclear]] stomachs{{RoyaltyIcon}} installed.

A pawn that is vomiting will stop in place, face the side, and begin vomiting. Vomiting lasts a random duration from {{Ticks|300}} to {{Ticks|900}}, and every 150 interval ticks it reduces the pawn's food bar by 0.04 and generates 1 stack of [[vomit]] filth on the tile they're facing. Note that this interval tick occurs independently from the beginning of the vomiting duration, and as such the number of times it occurs may not be the simple division of the chose duration divided by 150. As such, between one fewer and one more interval may occur than the the division would indicate. A pawn lying in a bed will not stand up to vomit{{Check Tag|Details|Does this pause the resting bonus from lying down? Does it wake them up?}}.

Vomiting will interrupt most tasks, including eating, walking, aiming a weapon, or working at a station, but they will resume the task once they stop vomiting{{Check Tag|Mechanics|Do pawns who are actively vomiting still reserve the task they were working on?}}. For this reason, it is recommended that pawns who are afflicted with an ailment that causes frequent vomiting, such as [[food poisoning]], eat foods like [[pemmican]], as a pawn who vomits while in the middle of eating a normal meal will lose all progress towards consuming it (note that the meal is not wasted), but a pawn eating pemmican will still consume part of the stack. Similarly, they should also avoid long tasks that have their progress reset on being interrupted, such as cooking 4x [[lavish meal]]s.

=== Crumbling mind ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}

The gradual breakdown of the mind. While technically non-fatal, it applies mounting consciousness penalties, and its final stage renders a pawn incapable of nearly all work.

Crumbling mind is caused by two [[Anomaly]] events - The [[Corrupted obelisk]] and the [[Creepjoiner]]. It cannot affect pawns that existed before those events, only ones created by them. It can be detected before ailments show by a surgical inspection.

Creepjoiners with this condition will begin showing symptoms within 2-3.33 days. Duplicated pawns will begin showing them within 12-48 hours. Severity progresses by 33% per day. Progress can be paused through the use of a [[cryptosleep casket]].

Crumbling mind can be cured by a [[healer mech serum]] as well as the [[unnatural healing]] ability so long as it hasn't progressed to the final stage of '''Crumbled mind'''. Once it has, the condition is incurable, short of destroying the colonists brain then resurrecting them with either a [[resurrector mech serum]] or [[death refusal]]. However, consistently destroying the brain can be difficult. There are 5 main ways to archive it:
* With the [[Biotech DLC]], using a [[Subcore ripscanner]] on the colonist in question will kill it by destroying its brain.
* Also with the Biotech DLC, extracting the pawn's genes with a [[Gene extractor]] while the '''Genes Regrowing''' Hefiff remains active will kill it by brain destruction.
* With the [[Ideology DLC]], extracting the [[skull]] from a dead pawn will destroy its head reliably and safely.
* Fatal [[Luciferium]] withdraw kills by destroying the brain.
* Allow colonists or animals to eat sections of the corpse, risking consuming the entire body before the head is removed.

Furthermore, no matter how successful the head removal, the costs and downsides of the either the serum or refusal remain. If this strategy is used, remember not to euthanize them or they will be no longer of your faction after resurrection.

Counterintuitively, [[Ghoul|ghoul infusion]] will not cure crumbling mind and it will hinder ghoul's combat abilities.

=== Duplicate sickness ===
{{Anomaly|section = 1}}
{{Spoiler|section = 1}}
Psychic interference between this person and their duplicate is causing slow mental deterioration. As long as multiple copies of this person are alive, the condition will keep getting worse. However, the condition will not be lethal.

Duplicate sickness is one of the potential outcomes from the duplication of a pawn by a [[corrupted obelisk]]. It affects both the original pawn and the duplicate{{Check Tag|Wb other duplicates?|Test both a previous duplicate (i.e. use obelisk gizmo, wait cooldown use again) and mass cloning (i.e. when 30 pawns spawn when it reaches max activity}} and is initially hidden. Severity increases by 10% per day that both pawns are alive{{Check Tag|Wb in crypto?|Does severity increase if the pawn is in cryptosleep? If no, does it pause on both or just the one in crypto? If no, wb if both are in crypto?}} and gradually reduces the consciousness of both pawns and makes them more likely to have [[mental breaks]], before eventually rendering both comatose.

It cannot be treated,{{Check Tag|Verify}} but can be cured by one of three methods: [[healer mech serum]], the [[unnatural healing]] ability, or the death of one of the two pawns.

If one of the two connected pawns is killed, the other's duplication sickness severity immediately starts regressing at the rate of 50% per day, while the killed pawn's duplication sickness is instantly cured. The killed pawn can then be immediately resurrected with a [[resurrector mech serum]] or [[death refusal]] without stopping the regression of the other pawn's sickness. Similarly, if one of the linked pawns is turned into a [[ghoul]], killed, and revived with a [[ghoul resurrection serum]], the same mechanics apply.

== Surgical ==
These ailments happen with medical operations.

=== Anesthetic ===
Used in surgery to make sure that a pawn is unconscious. It can also be administered outside of operations using a medical bill, consuming medicine.

A pawn under anesthesia is unconscious for the first 6 hours, and the worst effects of anesthetic wear off after 12 hours, so arranging operations to be performed some time just before a pawn needs to sleep is recommended if you want them functioning the next work day.

Treatment:
* Wears off on its own between {{ticks|45000}} to {{ticks|75000}} even if severity has not reached 0%
** Surgery is unaffected even if it wears off before finished

==== Version history ====
Prior to 1.1 it lasted only {{ticks|15000}} and did not have any other stages afterwards.

== Resurrection ==
These may occur after a dose of [[resurrector mech serum]] is applied on a [[Death|dead]] pawn.

=== Resurrection sickness ===
After-effects of being resurrected by mechanite injection. Artificially-kickstarted body processes take time to rebalance themselves.

{| class="wikitable"

'''Probability:'''
* 100% chance of being applied

=== Blindness ===
Mechanites fail to properly repair the eyes, instead causing more damage to it, resulting in blindness.

* Replace eyes with [[bionic eye]]s or [[archotech eye]]s

'''Probability:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

=== Resurrection psychosis ===
Chaotic thought patterns caused by the decoherence of resurrection mechanites. Resurrection psychosis progresses and eventually causes total psychosis and [[death]].

The severity of the psychosis increases by 0.01 per day, meaning that it will kill in 100 days after resurrection, or 90 days after this ailment becoming visible. Hopefully this gives you enough time to find a [[healer mech serum]] to heal the ailment, find another [[resurrector mech serum]] to attempt the resurrection again once the psychosis has run its course, or build a [[cryptosleep casket]] to give you time to find either serum. There are no other ways to cure the disease.

'''Treatments:'''
* Healer mech serum
* Allowing the pawn to [[Death|die]] again, then resurrecting once more (rerolls the disease)

'''Probability of contracting:'''
* 2% chance when used at 0.1 days or less of decay
* Linearly increases to 80% after 5 days decayed

'''Prevention:'''
* Freeze corpses immediately after death. Corpses placed in a [[sarcophagus]] are still affected by the temperature of the room they are in, and can be removed later but are protected from butchering, hungry animals and assuming you build the sarcophagus from something [[Flammability|non-flammable]], [[fire]].

== Heart attack ==
Heart attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in humans), triggered by the [[Events#Birthday|birthday event]]. There must be 2 or more colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days):
* 0-60% of life expectancy: 99,999,999 - 99,999,999
* 60-80% of life expectancy: 99,999,999 - 2,500
* 80-100% of life expectancy: 2,500 - 300

Examples of intervals and chances:
* 70% of life expectancy (i.e. 56 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
* 90% of life expectancy (i.e. 72 in humans): 1,400 days (approx. 0.000714% per day)

=== Stages ===
{| class="wikitable"
|-
! Stage !! Begins at !! Symptoms

|'''Painful''' || 0% Severity ||

|-
|'''Debilitating''' || 60% Severity ||
* [[Consciousness]] max. 10% (Unconsciousness)
* [[Pain]] +60%
|-
|'''Fatal''' || 100% Severity ||
* [[Death]]
|}

==== Progression ====
Heart attacks always start at 40% severity. Each interval the heart attack severity will randomly change by a value between {{---|40%}} to {{++|60%}}. This means that it is possible for a heart attack to recover on its own, but usually (~76% likelihood){{Check Tag|Detail needed|How is this calculated??}} an untreated heart attack progresses to fatal severity. The interval between changes is random, and varies between {{Ticks|500}} and {{Ticks|10000}}.

==== Treatment ====
Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by {{---|30%}}. Successfully reducing severity below 0% will completely treat the heart attack.

The chance a particular treatment can succeed is 65% multiplied by the [[tend quality]], for an effective maximum of 84.5% with [[glitterworld medicine]].

==== Prevention ====
Replacing a pawn's heart with either a [[prosthetic heart|prosthetic]] or [[bionic heart]] will completely prevent heart attacks. Note however that while the bionic heart improves the [[blood pumping]] capacity, the prosthetic heart decreases it, and thus all of the stats and capacities it affects.

== Version history ==
* [[Version/0.7.581|0.7.581]] Added with cataracts and bad back
* [[Version/0.8.657|0.8.657]] - Added hypothermia, frostbite, heatstroke, and burns from being in areas with extreme temperatures.

* [[Version/0.10.785|0.10.785]] - Starvation and blood loss are now staged and affect consciousness as they worsen.
* [[Version/0.12.906|0.12.906]] - All organisms including animals have life expectancies and will develop chronic conditions like frailty or cataracts in old age. Heart attacks added.
* [[Version/0.13.1135|0.13.1135]] - Carcinoma, asthma, and hearing loss added.
* [[Version/1.0.0|1.0.0]] - Minor starvation (below 25% severity) no longer causes miscarriages.
* [[Version/1.1.0|1.1.0]] - Pregnant animal is no longer viewed as sick because pregnancy affects its capacities. and thus now sells for the same as one with no health conditions.
* [[Version/1.3.3117|1.3.3117]] - Extreme blood loss now reduces consciousness by 40% in addition to setting the capacity's max to 10%. Prior to this, pawns could nonsensically [[Death|die]] by healing from extreme to severe bloodloss if their consciousness was below 40% from other symptoms - extreme would simply max it at 10% but healing to severe would reduce it by 40% to 0% and kill the pawn.
* [[Version/1.4.3523|1.4.3523]] - Sterilized animals no longer lay eggs.
* [[Version/1.6.4518|1.6.4518]] - Vacuum exposure implemented with [[Odyssey]].

== Version history ==
* [[Ideology DLC]]: Release - Added.
* [[Version 1.4]]: Removed. Replaced by the mechanically identical '''Mechanoid detritus'''.
** The main difference being that Mechanoid detritus had graphic variants for every '''Ancient mechanoid''' type ruins instead of requiring to define different buildings per part.
* [[Version 1.5]]: '''Mechanoid detritus''' are replaced by [[Mechanoid slag chunk]].

Maximum Comfortable Temperature

Note that the default value is only used when it is not defined for species and that the listed effective bounds are for [[human]]s. Also note that higher maximum comfortable temperatures are better.

== Base value ==
The default base value for [[human]]s is {{Temperature|{{Q|Human|Max Comfortable Temperature}} }}. The collapsed table below shows the minimum and maximum temperatures of all pawns
Any unique temperature mechanics will be described on their individual pages.

: {{note|1|1}} Note: Despite having a minimum and maximum comfortable temperature defined, mechanoids are unaffected by temperature extremes.
: {{note|2|2}} Note: Unlike most pawns, insectoids do not experience hypothermia and death from low temperatures and instead experience hypothermic slowdown.

== Factors ==
There are three ways to increase a pawns maximum comfortable temperature, being [[Apparel]] and [[Genes]]{{BiotechIcon}} and hediffs. Note that insulation from apparel does not affect whether a pawn ''"Slept in the cold/heat"'' mood penalty, but the effects of genes do.

[[Apparel]] increases maximum comfortable temperature by its [[Insulation - Heat]] which is modified by its quality, and if [[stuffable]] by the insulation factor of the material from which it is made. Apparel will never decrease a pawns maximum comfortable temperature, so it is not necessary to remove clothing to make a pawn more comfortable. See [[Insulation]] for further details.

There are 3 genes{{BiotechIcon}} that affect a pawns maximum comfortable temperature:
* [[Heat weakness]]: {{--|{{Temperature|5||delta}}}}
* [[Heat tolerant]]: {{+|{{Temperature|10||delta}}}}
* [[Heat super-tolerant]]: {{+|{{Temperature|20||delta}}}}

There is one hediff that affects a pawn's minimum comfortable temperature:
* [[Ghoul]]:{{AnomalyIcon}} {{+|{{Temperature|40||delta}} }} - Note: Ghouls have significant limitation on their capabilities and cannot wear apparel.
* [[Shambler]]:{{AnomalyIcon}} {{+|{{Temperature|30||delta}} }} - Note: Shamblers are no longer controllable and have significant limitation on their capabilities.

== Analysis ==
The absolute highest a human's maximum comfortable heat can be, comes from these factors:

* Default value: {{Temperature|26}}
* [[Quality|Legendary]] [[hyperweave]] [[tribalwear]]: {{+|{{Temperature|25.7||delta}}}}
* [[Quality|Legendary]] [[phoenix armor]]{{RoyaltyIcon}}: {{+|{{Temperature|180||delta}}}}
* [[Quality|Legendary]] [[hyperweave]] [[cowboy_hat|cowboy hat]]/[[shadecone]]{{IdeologyIcon}}: {{+|{{Temperature|23.4||delta}}}}
* [[Quality|Legendary]] [[hyperweave]] [[face_mask|face mask]]{{BiotechIcon}}: {{+|{{Temperature|0.936||delta}}}}
* [[Heat super-tolerant]] gene{{BiotechIcon}}: {{+|{{Temperature|20||delta}}}}

'''Total: {{Temperature|276}}'''

Pawns and items will spontaneous ignite above {{Temperature|235}}, however, limiting the actual maximum temperature that a base can operate under below this value.
