While '''slavery''' technically exists in the base game, the [[Ideology DLC]] significantly adds to the system, allowing them to work and perform tasks. Slaves in base game RimWorld can only be sold for profit, with no other use.

'''Slavery''' in base game RimWorld is limited to selling [[prisoner]]s for profit, at the cost of a [[mood]] hit for anyone not a [[psychopath]]. Purchasing a slave, meanwhile, will immediately free them from slavery and join them into the colony, with a mood buff. The [[Ideology DLC]] significantly expands on the concept, allowing prisoners to be enslaved and forced to work and perform tasks.
 +
 
 +
== Acquiring slaves ==
 +
Slaves can be created by reducing the will of a [[prisoner]] to zero, or by attempting to enslave a prisoner while benefiting from a recruitment [[Mental inspiration#Inspired recruitment|inspiration]]. A prisoner's starting will is usually much lower than their resistance (which would recruit them as a colonist).
 +
 
 +
== Summary ==
 +
Slaves are controllable pawns, much like a colonist. They have many functional differences but act just the same. Slaves are prone to [[#Slave rebellion|slave rebellions]].
 +
 
 +
Slaves contribute 75% of the [[raid points]] of an equivalent colonist.

Slavery is a quick way to get decent amounts of money quickly. Pawns will suffer a mood penalty of -3, stacking up to -15 for 4 days once slaves are sold. Unless you have a colony of psychos, selling slaves may bring down your colony by lowering the moods of pawns by large increments. There is no way to mitigate the negative moodlet. One way of dealing with this is to sell only 1-2 slaves every day in the late game, when pawns can take [[drug]]s and eat [[lavish meal]]s, and avoiding slavery altogether in the early game. This has a downside, however. Traders generally only stay for around two days, and only appear occasionally, meaning that it will be hard making slavery the main source of profit for the colony. Alternatively, you can stuff all of your pawns into [[cryptosleep casket]]s or give them extra high accommodation to prepare for the massive mood debuff and have the best psychopath trader (if using the cryptosleep tactic, otherwise, use the best trader colony-wide) sell as many slaves as possible.
+
A slave will have 85% [[Global Work Speed]] - they have no motivation to work as hard. To compensate, they have no need for [[Recreation]], and will have increased mood through expectations.

==Ideology==
+
Slaves are unable to do the Warden, Art, or Research tasks. They are additionally unable to:
−
{{Ideology}}
+
* Tasks that require a minimum [[Intellectual]] skill greater than 0 such as crafting [[Medicine]] as slaves are considered to have 0 skill regardless of their actual skill level prior to enslavement. Despite [[Drug Synthesis Speed]] scaling with Intellectual they are still capable of doing tasks that use this stat for scaling, albeit slowly.
−
Slaves are controllable, like normal colonists, but with unique mechanics and restrictions.
+
* Request caravans, military aid, or persona core location via [[comms console]]
 +
* Call royal [[permit]]s{{RoyaltyIcon}}
 +
* Be an ideoligious [[role]]
 +
However, slavery overrides ''all'' other work exceptions. For example, if a colonist would be unable to do Dumb Labor, enslaving will force them to allow Dumb Labor.

* New incapabilities: cannot hunt, make art, research or warden. Slaves are also incapable of synthesising Drugs (cooking Drugs is still possible). Currently unclear if they can do other social activities like trade.
+
Slaves do not have the default [[expectations]] of colonists. Instead they have unique expectations with a generally higher mood boost. Slave expectations replace colonist expectations based on what the pawn's expectations would be if they were a colonist based on colony wealth and noble status.

=== Acquiring slaves ===

Slaves can be created by reducing the will of a prisoner to zero.
+
* Slaves never insult or social fight with non-slave pawns. They are half as likely to social fight with each other.
 +
* Slaves cannot share a [[double bed]] with non slaves colonists, even if they are married.
 +
* Slaves can share [[bed]]rooms with colonists, however the colonists will receive {{--|3}} mood for doing so (unless they are in a relationship).
 +
 
 +
Other colonists will see slavery as either an abhorrent or honorable act, depending on the Slavery [[precept]].
 +
 
 +
== Slave rebellion ==
 +
Slaves will occasionally rebel, staging something similar to a prison break. Slaves will turn hostile and uncontrollable, and will try to find weapons to attack nearby colonists. The rebellion interval is based on mood, suppression, proximity of weapons, escape route, and the presence of colonists on the map, with a base interval of 45 days. The time displayed is based on time awake - that is, if a slave sleeps 8 hours of every 24, the actual mean time between rebellions will be 50% longer. A displayed MTB of 2 years will actually be a MTB of 3 years.
 +
 
 +
Slave rebellions come in several different types: Grand, Local, and Single. A grand escape involves every valid slave on the map rebelling, while a local escape chooses a given slave as a locus with any valid slaves within 35 tiles also rebelling. A single rebellion is, as the name implies, a rebellion by a single slave.
 +
 
 +
Only non-downed, non-mental breaking, awake, slaves can join a rebellion. Thus, by assigning slaves different shifts, the maximum number of slaves rebelling can be limited.
 +
 
 +
Weapons such as [[Wood]], [[EMP grenades]]/[[EMP launcher|launchers]], and [[Smoke launcher]]s will not increase rebellion chance, despite being weapons. Rebellious slaves will take ranged weapons even if equipped with [[shield belt]]s, dropping the belts in the process.
 +
 
 +
{| class="wikitable"
 +
| '''Mean Time Between Rebellions''' = 45/(Moving Factor * Suppression Factor * Slave Count Factor * Mood Factor * Room Edge Factor * Weapon Factor * Unattended Factor)
 +
|}
 +
Where:
 +
* Moving Factor = A curve dependent on the current [[Moving]] capacity of the slave, defined by 3 points and linearly interpolated between them. 0.01x at 0% (though note that a pawn that cannot move is not valid for a rebellion anyway), 0.5x at 50% and 1x at 100%. This very closely approximates a straight scalar based on the Moving capacity, but is slightly different. Also note that this is Moving capacity, not [[move speed]], so slowing a pawn down with [[peg leg]]s will make rebellions less frequent, but slowing them down with a [[flak vest]] will not.
 +
* Suppression Factor = A curve dependent on the current suppression value of the slave, defined by 4 points and linearly interpolated between them. 5x at 0%, 1.5x at 33.3%, 1x at 50%, 0.25x at 100%.
 +
* Slave Count Factor = A curve dependent on the number of slaves loaded on a map, defined by 5 points and linearly interpolated between them. 1x at 1 slave, 0.75x at 2 slaves, 0.5x at 5 slaves, 0.3x at 10 slaves. 0.2x at 20 slaves. Note that despite making each slave individually less likely to rebel, having more slaves rolling for rebellions actually increases the chance. Also note that these slaves don't need to be valid slaves for a rebellion, they must simply be alive and on the map.
 +
* Mood Factor = A curve dependent on the [[mood]] of the slave, defined by three points and linearly interpolated between them. 1.5x at 0% mood, 1x at 50% mood, 0.8x at 100% mood.
 +
* Room Edge Factor = 1.7 when in a room that touches the map edge including being completely outdoors. 1 otherwise.
 +
* Weapon Factor = 4 when within 7 tile range of a usable weapon, or if indoors (in a room not considered outdoors) in the same room as a usable weapon. 1 otherwise. [[Body part weapons]] do not count for the purposes of this check.{{Check Tag|Verify}}
 +
* Unattended Factor = 20 when on a map without a colonist that is not downed, dead or a slave. 1 otherwise.
  
−
=== Slave relationships ===
+
== Wardening ==
−
Slaves can start relationships with any other slave or even another colonist. This is troublesome, as slaves cannot be assigned to the same bed as a colonist, but can still sleep in the same room. If you want both to be together, you need to make either both slaves or both colonists.
+
Like [[prisoner]]s, slaves can be interacted with by colonists with the Warden task.
  
−
=== Slave rebellion ===
+
* '''Suppress''' - Intimidate the slave, causing their suppression to rise up, which lowers the chance of rebellion.
−
Slaves will occasionally rebel, staging something similar to a prison break. Slaves will turn hostile and uncontrollable, and will try to find weapons to attack nearby colonists. The rebellion interval is based on mood, suppression, proximity of weapons, and colonists present on the map, with a base interval of 45 days.
+
* '''Imprison''' - Arrest the slave, turning them back into a [[prisoner]]. You will need to reduce their will again to enslave them again.
 +
* '''Emancipate''' - Free the slave. If the slave belonged to another faction, you will gain [[goodwill]] with that faction.
 +
* '''Execute''' - Kill the slave.
  
−
Note that weapons such as [[Wood]], [[EMP grenades]]/[[EMP launcher|launchers]], and [[Smoke launcher]]s will not increase rebellion chance, despite being weapons. Also note that rebellious slaves will take ranged weapons, even if equipped with [[shield belt]]s, dropping the belts in the process.
+
== Suppression ==
 +
Suppression is one of the stats used to calculate the slave rebellion interval. The higher the suppression, the longer the expected interval in between rebellions. The suppression of a slave can be increased by interacting with them, melee attacking them with a colonist or executing other slaves or prisoners. Over time, the suppression level lowers depending on its current level by up to 20% per day.

Suppression is one of the stats used to calculate the slave rebellion interval. The higher the suppression, the longer the expected interval in between rebellions. The suppression of a slave can be increased by interacting with them, melee attacking them with a colonist or executing other slaves or prisoners.

A suppression loss of less than 0% per day will not increase the suppression. Since the default loss is at a maximum of 20% per day, a slave collar combined with body straps is enough to keep up the suppression of a slave unless they are wearing apparel that increases suppression loss above 10%. Since a negative loss has no effect, increasing Terror while slaves wear slave collars and body straps is useless unless you also wish to outfit the slave with suppression-decreasing apparel, such as dusters in hot [[biomes]] or marine armor for combat slaves.

 +
=== Warden suppression ===
 +
Each time a warden suppresses a slave, it increments their suppression by a value dependent on the [[Suppression Power]] of the warden and the current suppression of the slave.

For example, a colonist with [[Skills#Social|Social]] skill of 10 has a Suppression Power of 28%. A slave with a current Suppression value of 0 has a suppression curve factor of 2x. Thus, that colonist suppressing that slave would result in the slave's suppression increasing by 56%. This also means that a skill 20 pawn will always fully supress a slave.
 +
 
 +
Each suppression attempt takes {{ticks|180}} of work.
 +
 
 +
[[Authority cap]]s improve the suppression power of the wearer. See that page for details.
 +
 
 +
=== Melee suppression ===
 +
{{Stub|section=1|reason=Exact equation depends on CurrentSuppressionFactorCurve - needs to be worked out and added}}
 +
Any colonist can suppress a pawn by performing melee attacks against them. Each attack increases suppression at a rate dependent on the current suppression and the damage dealt, with more damage suppressing more
 +
 
 +
=== Terror ===
 +
{{Stub|section=1|reason=needs specifics}}
 +
Terror is a way to keep slaves suppressed. It rises when the slave spends time near terrifying things like terror sculptures. A slave can only be affected by three terror sources at a time. While terror is high, suppression falls slower.
 +
 
 +
Terror can be created by having slaves in proximity to terror creating furniture like [[skullspike]]s, [[terror sculpture]]s or bodies in [[gibbet cage|cages]]. While slaves are affected by these, their suppression loss is lowered, depending on the value and amount of terror sources, but capped at 3 individual sources.
 +
 
 +
== Analysis ==
 +
Keep slaves in collars and straps. Barring that, build terrorizing furniture in the areas they spend the most time ''awake'' in, such as workshops and kitchens. Terror fixtures are of little use inside a slave's own room.
 +
 
 +
Keep your weapons inside a room that slaves will rarely, if ever, approach; confining your slaves to a restrictive allowed [[Zone/Area#Allowed area|area]] helps, of course.
 +
 
 +
Minimize or eliminate the time slaves have access to the map edge. Consider walling off the area that slaves live in, if your entire colony isn't walled off already (doors count as barriers for purposes of map edge access for slaves). If that isn't feasible, keep slaves near the center of your colony as much as possible, and build walls and doors blocking off the ends of alleyways (this also helps slow down raiders that get past your outer defenses or land inside your base outright). Again, confining slaves to an allowed area is critical.
 +
 
 +
Consider keeping your slaves happy. This is much easier than it might seem, since slaves have a huge baseline mood boost compared to a typical colonist, and will never get upset about lack of recreation. Slaves also get mood bonuses from performing work they're [[Passion|passionate]] about; paradoxically, these bonuses can last longer because the slave need not take recreation breaks. Having them drink [[psychite tea]] every other day will not only boost their mood further but also slightly increase their productivity (though unfortunately the big increase to recreation is wasted). Because slaves return to their rooms by default when in need of medical care, consider making their floors [[steel tile]] for an admittedly expensive increase to both cleanliness and room beauty. Also consider sticking "hand-me-down" beautifying [[sculptures]] in their rooms instead of just selling the old art. On the other hand, [[ascetic]] slaves allow you to have a happy slave with the crummiest room possible. [[Masochist]] slaves will love having a mindscrew implant (though it will lower their sale price), and the pain will lower consciousness, reducing their movement potential and further discouraging rebellion. Or just punch them once in a while. They also like wearing the collar and straps that all slaves should wear anyway. Not only do happy slaves rebel a bit less often, joyful slaves can benefit from [[inspirations]] as other colonists do, making them even more useful as your property.
 +
 
 +
If you have the [[Royalty]] DLC, consider giving slaves brain implants that cause [[brain shock]] so rebellions can be safely suppressed with no loss of life, even with armed and armored slaves, by using [[EMP]] weapons. Implants such as the [[circadian half-cycler]]{{RoyaltyIcon}} and the [[circadian assistant]]{{RoyaltyIcon}} also increase the total productivity of the slave, and the half-cycler reduces movement capacity by reducing consciousness; the downside is that these implants increase time awake, lowering the MTB for rebellions.

===== Terror =====
+
If you have the [[Anomaly]] DLC, the Bliss Lobotomy procedure can be learned and performed to massively reduce the frequency of an individual slave's rebellion interval at the cost of no longer being able to perform skilled labor and reducing their learning speed. This makes it a very compelling option for slave whose primary role is Hauling, Cleaning, Animal Handling, and/or Doctoring. Lobotomized slaves are so compliant that even when armed their rebellion interval more closely matches that of a normal, unarmed slave. While not entirely without risk, this makes enslaved combatants a viable option especially if they are only armed when there is an active threat. It is important to note that while a lobotomized slave may almost never rebel themselves, other non-lobotomized slaves may start a group rebellion and cause lobotomized slaves to join regardless.

Slaves can be given honor and ascend the ranks of royalty just as every other pawn can. They function much the same as other nobles, requiring specific clothes, certain standards of bedroom and throne room, etc. with two major exceptions. First is they cannot use permits. Second is that slavery overrides the work type restrictions from conceited nobility.

This article relates to content added by Ideology (DLC). Please note that it will not be present without the DLC enabled.
Rewrite.png
This article is suggested to be rewritten. Reason: Previous major rewrite lost information re: raid points. Verify any other losses. You can help the RimWorld Wiki by improving it.
For selling prisoners, which is also considered "slavery" , see Prisoners.

Slavery in base game RimWorld is limited to selling prisoners for profit, at the cost of a mood hit for anyone not a psychopath. Purchasing a slave, meanwhile, will immediately free them from slavery and join them into the colony, with a mood buff. The Ideology DLC significantly expands on the concept, allowing prisoners to be enslaved and forced to work and perform tasks.

Acquiring slaves[edit]

Slaves can be created by reducing the will of a prisoner to zero, or by attempting to enslave a prisoner while benefiting from a recruitment inspiration. A prisoner's starting will is usually much lower than their resistance (which would recruit them as a colonist).

Summary[edit]

Slaves are controllable pawns, much like a colonist. They have many functional differences but act just the same. Slaves are prone to slave rebellions.

Slaves contribute 75% of the raid points of an equivalent colonist.

Work[edit]

A slave will have 85% Global Work Speed - they have no motivation to work as hard. To compensate, they have no need for Recreation, and will have increased mood through expectations.

Slaves are unable to do the Warden, Art, or Research tasks. They are additionally unable to:

  • Tasks that require a minimum Intellectual skill greater than 0 such as crafting Medicine as slaves are considered to have 0 skill regardless of their actual skill level prior to enslavement. Despite Drug Synthesis Speed scaling with Intellectual they are still capable of doing tasks that use this stat for scaling, albeit slowly.
  • Request caravans, military aid, or persona core location via comms console
  • Call royal permitsContent added by the Royalty DLC
  • Be an ideoligious role

However, slavery overrides all other work exceptions. For example, if a colonist would be unable to do Dumb Labor, enslaving will force them to allow Dumb Labor.

Unlike prisoners, male slaves can fertilize embryos.Content added by the Biotech DLC

Expectations[edit]

See also: Expectations

Slaves do not have the default expectations of colonists. Instead they have unique expectations with a generally higher mood boost. Slave expectations replace colonist expectations based on what the pawn's expectations would be if they were a colonist based on colony wealth and noble status.

Expectation Mood Effect Replaces Colonist Expectation
Destitute slave expectations +46 Extremely low expectations
Poor slave expectations +40 Very low expectations
Meager slave expectations +34 Low expectations
Slave expectations +28 All other Expectations

Relationships[edit]

  • Slaves never insult or social fight with non-slave pawns. They are half as likely to social fight with each other.
  • Slaves cannot share a double bed with non slaves colonists, even if they are married.
  • Slaves can share bedrooms with colonists, however the colonists will receive −3 mood for doing so (unless they are in a relationship).

Other colonists will see slavery as either an abhorrent or honorable act, depending on the Slavery precept.

Slave rebellion[edit]

Slaves will occasionally rebel, staging something similar to a prison break. Slaves will turn hostile and uncontrollable, and will try to find weapons to attack nearby colonists. The rebellion interval is based on mood, suppression, proximity of weapons, escape route, and the presence of colonists on the map, with a base interval of 45 days. The time displayed is based on time awake - that is, if a slave sleeps 8 hours of every 24, the actual mean time between rebellions will be 50% longer. A displayed MTB of 2 years will actually be a MTB of 3 years.

Slave rebellions come in several different types: Grand, Local, and Single. A grand escape involves every valid slave on the map rebelling, while a local escape chooses a given slave as a locus with any valid slaves within 35 tiles also rebelling. A single rebellion is, as the name implies, a rebellion by a single slave.

Only non-downed, non-mental breaking, awake, slaves can join a rebellion. Thus, by assigning slaves different shifts, the maximum number of slaves rebelling can be limited.

Weapons such as Wood, EMP grenades/launchers, and Smoke launchers will not increase rebellion chance, despite being weapons. Rebellious slaves will take ranged weapons even if equipped with shield belts, dropping the belts in the process.

Mean Time Between Rebellions = 45/(Moving Factor * Suppression Factor * Slave Count Factor * Mood Factor * Room Edge Factor * Weapon Factor * Unattended Factor)

Where:

  • Moving Factor = A curve dependent on the current Moving capacity of the slave, defined by 3 points and linearly interpolated between them. 0.01x at 0% (though note that a pawn that cannot move is not valid for a rebellion anyway), 0.5x at 50% and 1x at 100%. This very closely approximates a straight scalar based on the Moving capacity, but is slightly different. Also note that this is Moving capacity, not move speed, so slowing a pawn down with peg legs will make rebellions less frequent, but slowing them down with a flak vest will not.
  • Suppression Factor = A curve dependent on the current suppression value of the slave, defined by 4 points and linearly interpolated between them. 5x at 0%, 1.5x at 33.3%, 1x at 50%, 0.25x at 100%.
  • Slave Count Factor = A curve dependent on the number of slaves loaded on a map, defined by 5 points and linearly interpolated between them. 1x at 1 slave, 0.75x at 2 slaves, 0.5x at 5 slaves, 0.3x at 10 slaves. 0.2x at 20 slaves. Note that despite making each slave individually less likely to rebel, having more slaves rolling for rebellions actually increases the chance. Also note that these slaves don't need to be valid slaves for a rebellion, they must simply be alive and on the map.
  • Mood Factor = A curve dependent on the mood of the slave, defined by three points and linearly interpolated between them. 1.5x at 0% mood, 1x at 50% mood, 0.8x at 100% mood.
  • Room Edge Factor = 1.7 when in a room that touches the map edge including being completely outdoors. 1 otherwise.
  • Weapon Factor = 4 when within 7 tile range of a usable weapon, or if indoors (in a room not considered outdoors) in the same room as a usable weapon. 1 otherwise. Body part weapons do not count for the purposes of this check.[Verify]
  • Unattended Factor = 20 when on a map without a colonist that is not downed, dead or a slave. 1 otherwise.

Wardening[edit]

Like prisoners, slaves can be interacted with by colonists with the Warden task.

  • Suppress - Intimidate the slave, causing their suppression to rise up, which lowers the chance of rebellion.
  • Imprison - Arrest the slave, turning them back into a prisoner. You will need to reduce their will again to enslave them again.
  • Emancipate - Free the slave. If the slave belonged to another faction, you will gain goodwill with that faction.
  • Execute - Kill the slave.

Suppression[edit]

Suppression is one of the stats used to calculate the slave rebellion interval. The higher the suppression, the longer the expected interval in between rebellions. The suppression of a slave can be increased by interacting with them, melee attacking them with a colonist or executing other slaves or prisoners. Over time, the suppression level lowers depending on its current level by up to 20% per day.

Suppression Suppression loss
(per day)
30% - 100% −20%
>15% - <30% −10%
0% - 15% −5%

The amount of suppression lost can be increased or decreased if the slave is wearing the following things:

Item Suppression loss offset
(per day)
Slave collar +15%
Slave body strap +15%
Cowboy hat −5%
Bowler hat −5%
Tribal headdress −10%
Veil −10%
Marine helmet −10%
Duster −5%
Marine armor −30%
Prestige marine helmet Content added by the Royalty DLC −10%
Prestige marine armor Content added by the Royalty DLC −30%
Grenadier armor Content added by the Royalty DLC −30%
Eltex shirt Content added by the Royalty DLC −20%
Eltex vest Content added by the Royalty DLC −20%
Eltex robe Content added by the Royalty DLC −20%
Formal shirt Content added by the Royalty DLC −10%
Corset Content added by the Royalty DLC −10%
Formal vest Content added by the Royalty DLC −10%
Prestige robe Content added by the Royalty DLC −20%
Ladies hat Content added by the Royalty DLC −5%
Top hat Content added by the Royalty DLC −5%
Coronet Content added by the Royalty DLC −20%
Crown Content added by the Royalty DLC −30%
Stellic crown Content added by the Royalty DLC −30%
Beret Content added by the Royalty DLC −5%
Mechlord suitContent added by the Biotech DLC −30%

A suppression loss of less than 0% per day will not increase the suppression. Since the default loss is at a maximum of 20% per day, a slave collar combined with body straps is enough to keep up the suppression of a slave unless they are wearing apparel that increases suppression loss above 10%. Since a negative loss has no effect, increasing Terror while slaves wear slave collars and body straps is useless unless you also wish to outfit the slave with suppression-decreasing apparel, such as dusters in hot biomes or marine armor for combat slaves.

Warden suppression[edit]

Each time a warden suppresses a slave, it increments their suppression by a value dependent on the Suppression Power of the warden and the current suppression of the slave. Namely:

Suppression Change = Suppression Power * Suppression Curve Factor
CurrentSuppressionFactorCurve

For example, a colonist with Social skill of 10 has a Suppression Power of 28%. A slave with a current Suppression value of 0 has a suppression curve factor of 2x. Thus, that colonist suppressing that slave would result in the slave's suppression increasing by 56%. This also means that a skill 20 pawn will always fully supress a slave.

Each suppression attempt takes 180 ticks (3 secs) of work.

Authority caps improve the suppression power of the wearer. See that page for details.

Melee suppression[edit]

StumpChoppedA (cropped).png
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Exact equation depends on CurrentSuppressionFactorCurve - needs to be worked out and added.

Any colonist can suppress a pawn by performing melee attacks against them. Each attack increases suppression at a rate dependent on the current suppression and the damage dealt, with more damage suppressing more

Terror[edit]

StumpChoppedA (cropped).png
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: needs specifics.

Terror is a way to keep slaves suppressed. It rises when the slave spends time near terrifying things like terror sculptures. A slave can only be affected by three terror sources at a time. While terror is high, suppression falls slower.

Terror can be created by having slaves in proximity to terror creating furniture like skullspikes, terror sculptures or bodies in cages. While slaves are affected by these, their suppression loss is lowered, depending on the value and amount of terror sources, but capped at 3 individual sources.

Analysis[edit]

Keep slaves in collars and straps. Barring that, build terrorizing furniture in the areas they spend the most time awake in, such as workshops and kitchens. Terror fixtures are of little use inside a slave's own room.

Keep your weapons inside a room that slaves will rarely, if ever, approach; confining your slaves to a restrictive allowed area helps, of course.

Minimize or eliminate the time slaves have access to the map edge. Consider walling off the area that slaves live in, if your entire colony isn't walled off already (doors count as barriers for purposes of map edge access for slaves). If that isn't feasible, keep slaves near the center of your colony as much as possible, and build walls and doors blocking off the ends of alleyways (this also helps slow down raiders that get past your outer defenses or land inside your base outright). Again, confining slaves to an allowed area is critical.

Consider keeping your slaves happy. This is much easier than it might seem, since slaves have a huge baseline mood boost compared to a typical colonist, and will never get upset about lack of recreation. Slaves also get mood bonuses from performing work they're passionate about; paradoxically, these bonuses can last longer because the slave need not take recreation breaks. Having them drink psychite tea every other day will not only boost their mood further but also slightly increase their productivity (though unfortunately the big increase to recreation is wasted). Because slaves return to their rooms by default when in need of medical care, consider making their floors steel tile for an admittedly expensive increase to both cleanliness and room beauty. Also consider sticking "hand-me-down" beautifying sculptures in their rooms instead of just selling the old art. On the other hand, ascetic slaves allow you to have a happy slave with the crummiest room possible. Masochist slaves will love having a mindscrew implant (though it will lower their sale price), and the pain will lower consciousness, reducing their movement potential and further discouraging rebellion. Or just punch them once in a while. They also like wearing the collar and straps that all slaves should wear anyway. Not only do happy slaves rebel a bit less often, joyful slaves can benefit from inspirations as other colonists do, making them even more useful as your property.

If you have the Royalty DLC, consider giving slaves brain implants that cause brain shock so rebellions can be safely suppressed with no loss of life, even with armed and armored slaves, by using EMP weapons. Implants such as the circadian half-cyclerContent added by the Royalty DLC and the circadian assistantContent added by the Royalty DLC also increase the total productivity of the slave, and the half-cycler reduces movement capacity by reducing consciousness; the downside is that these implants increase time awake, lowering the MTB for rebellions.

If you have the Anomaly DLC, the Bliss Lobotomy procedure can be learned and performed to massively reduce the frequency of an individual slave's rebellion interval at the cost of no longer being able to perform skilled labor and reducing their learning speed. This makes it a very compelling option for slave whose primary role is Hauling, Cleaning, Animal Handling, and/or Doctoring. Lobotomized slaves are so compliant that even when armed their rebellion interval more closely matches that of a normal, unarmed slave. While not entirely without risk, this makes enslaved combatants a viable option especially if they are only armed when there is an active threat. It is important to note that while a lobotomized slave may almost never rebel themselves, other non-lobotomized slaves may start a group rebellion and cause lobotomized slaves to join regardless.

Genes[edit]

This section relates to content added by Biotech (DLC). Please note that it will not be present without the DLC enabled.

Genetically modifying slaves is overall essential for improving how efficient they are at work and countering their faults.

Countering Rebellions
Gene Total Metabolic Efficiency Commentary
Extra pain +2 forces the wimp trait increasing pain shock threshold, this allows rebellions to be dealt with quicker and with less risk of killing the slave, mental breaks should they occur can be dealt with in the same way.
Weak melee damage
Nearsighted		 +1
+2		 Should be added over violence disabled this is because pawns incapable of violence will still participate in rebellions and the gene overrides the two actually impactful genes for combat.
Awful shooting/melee
Poor shooting/melee		 +2
+1		 Lowers the skills that they will use for combat during rebellions in addition to being essentially free metabolic efficiency
Very happy −2 indirectly makes rebellions less frequent by improving their mood.
Superfast wound healing
Fast wound healing		 −3
−2		 Allows slaves to recover faster after being beaten during rebellions or mental breaks, damaging slaves in melee also raises their suppression far quicker then a warden doing it
Heat/Cold super-tolerant
Heat/Cold tolerant
Furskin
Furry tail		 −2
−1
−1
−1		 Should be added if in hot or cold biomes this is because Slave body straps occupy the outer layer thus they cannot be equipped with parkas or dusters missing out on additional slave suppression offset.
Improving and countering their faults
Gene Total Metabolic Efficiency Commentary
Very unattractive
Unattractive		 +2
+1		 While slaves cannot be ordered to romance other colonists, they will still do it on their own terms, these genes while being free also reduce the chance of undesirable relationships from forming, thus negating the sleeping alone and "My <relationship> died" moodlets slaves cannot share beds with colonists and cannot do loving either.
Awful intellect/artistic
Poor intellect/artistic		 +2
+1		 These skills cannot be used so free metabolic efficiency
No sleep
Low sleep		 −6
−4		 can be installed to increase how long slaves are awake for and thus working combined with the lack of recreation need, Makes rebellions larger due to more slaves being awake at the same time.
Smooth tail
Elongated fingers		 −1
−1		 improves manipulation offsetting the lowered work speed.
Great aptitude
Good aptitude		 −3
−1		 Overall depends on what you want the slave to be specialized towards, Crafting can be installed to allow the slave to craft components far sooner, while Mining can allow them to work faster at drills or clearing areas for building, these can turn what is otherwise a garbage pawn into one specialized for certain petty tasks far quicker.

Titles[edit]

This article relates to content added by Royalty (DLC). Please note that it will not be present without the DLC enabled.
Main article: Titles

Slaves can be given honor and ascend the ranks of royalty just as every other pawn can. They function much the same as other nobles, requiring specific clothes, certain standards of bedroom and throne room, etc. with two major exceptions. First is they cannot use permits. Second is that slavery overrides the work type restrictions from conceited nobility.

Version history[edit]

  • Between 1.2.2723 and 1.3.3087 - Slave sold penalty reduced from -5 to -3.
  • 1.3.3072 - Tune slave rebellion chances a bit lower, and reduce the effects of some factors. Slave weapon noticing distance reduced from 10 to 6.9. Couples made of a slave/colonist pair no longer want to sleep together despite not being able to share a bed.
  • 1.3.3074 - Slaves no longer slight or insult non-slaves, Slaves never start social fights with non-slaves if insulted, Meleeing a slave now increases suppression, Rebellion chance per slave now relates inversely to the number of slaves on the map, so overall rebellion chance shouldn't climb so aggressively with higher slave counts, Adjust slave rebellion base MTB 50 days back to 45 days. Ideoligion funerals are no longer expected for slaves. Slaves no longer count for Diversity of Thought. More selective in which weapons increase rebellion chance - now excludes Wood, EMP, Smoke etc.
