Characters, like colonists, raiders, etc, can become injured (via the environment or fighting).

Each injury affects a different part of the colonists' well being, and can be found under a character's Health tab.

Under the health tab there are two sub-tabs, one for a health overview and a second tab for scheduling any operations that a colonist requires.

Health Systems


Pawns have the following health systems.

  1. Refers to whether or not the pawn will die if a system's capacity becomes 'None'
  2. Centipedes body rings are used for movement instead, since they don't have legs.
  3. Again, Centipedes body rings are used for work instead, since they don't have arms.
  4. Centipedes have no form of external communication. Scythers do have a neck though, and make some interesting sounds when incapacitated.

Pain

Main Article: Pain

Most biological creatures including colonists, raiders, and animals feel pain caused by injuries. A pawn's pain level ranges from 0% to 100% and is displayed on their Health tab's Overview. Pain levels are None, Little, Moderate, Severe, and Extreme.[Detail Needed] Even a little pain causes unhappy thoughts. Once pain passes 10%, it'll start to have an effect on consciousness. If a pawn's pain level meets or exceeds their Pain Shock Threshold they'll go into shock, unable to move. Pawns with the Wimp trait will be incapacitated with only minor pain of 30%.

Most pain is temporary, but scars and certain diseases can cause long-term pain. A painstopper implant or the Painblock psycast Content added by the Royalty DLC will get rid of all a colonist's pain and negate any pain-related mood penalties. Note that colonists with the Masochist trait or an ideoligion with the Pain: Idealized preceptContent added by the Ideology DLC get a mood bonus from pain instead of a penalty, so it's usually better to leave them alone.

Injuries to the artificial parts do not cause any pain, so colonists with a lot of bionics will generally incur less pain during combat.

Formula

Pain for a given pawn is the sum of the pain from each individual injury, with two extra steps at the end:

  • pain = pain / healthFactor for pawns with a healthFactor other than 1.0 (like grizzly bears and other large animals). Humans have a healthFactor of 1.0, so this doesn't impact humans
  • pain = pain * painFactor from health conditions which alter pain. This includes pain-reducing drugs like flake and yayo as well as anesthetic used during operations

Pain from an individual injury is the product of the severity of the injury (the number of HP missing for things like cuts and burns) and the pain per severity for the injury type. For example:

  • 30 burn damage causes 30 damage × 0.01875 pain per severity = 56.25% pain
  • 30 cut damage causes 30 damage × 0.0125 pain per severity = 37.5% pain

For the complete table of pain vs damage, see Health Difficulties

Thresholds

Pain creates moodlets of different values at 4 stages depending on pain severity.

Level Required Pain % Mood Penalty
(Default)
Mood Buff
(Masochist)
Mood Buff
(Pain:IdealizedContent added by the Ideology DLC)
Minor 1% −5 +5 +3
Serious 15% −10 +10 +5
Intense 40% −15 +15 +7
Mind-shattering 80% −20 +20 +9

A standard pawn will go down upon reaching mind-shattering pain.
Pain inflicts a consciousness penalty that scales with the pain percentage after exceeding 10%. It conforms to the following equation: IF Pain[%] <= 10% THEN -0% ELSE -{(Pain-0.1)/2.25}[%] For example, 15% pain is 0.15 - 0.1 = 0.05 / 2.25 = 0.02 or 2% consciousness loss.

Factors

Base factors

Factors cause the game code to MULTIPLY pain X a number. Small numbers reduce pain a lot. Large numbers reduce pain a little.

Offsets

Offsets cause the game code to ADD OR SUBTRACT a number from the pawn's pain. Small numbers are less effective at reducing pain than large numbers. However, if the pawn only has a small amount of pain, an equally small offset will be totally effective at removing all pain. Positive numbers add pain. Negative numbers reduce pain.


Consciousness

Consciousness is a creature's ability to remain active, and in the case of your colonists, controllable. Blood loss and starvation can have a serious effect on a creature's consciousness if they reach higher levels. When a medical operation is performed, the consciousness of the colonist is dropped to very poor and remains that way until a short period of time has passed. This makes them incapable of moving, along being incapable of leaving the bed.

Sight

Sight is a capacity that contributes to stats including shooting accuracy, melee hit chance, and for colonists, nearly every work stat. Humans and animals have eyes, while scythers and centipedes have functionally equivalent sight sensors. Losing and eye or sensor reduces sight by 50%. Humans aged 60 or older may develop cataracts which reduces drastically reduces sight by 70%. An eye can be upgraded with a bionic eye.

Hearing

Hearing is a capacity that contributes to trade price improvement. Hearing is reduced by damaged or missing ears. It is also be reduced by dementia.

Moving

Moving is a capacity that determines a pawn's movement speed. Nearly all pawns use legs to move about. A pawn's movement speed is reduced when a leg, foot, or toe is injured. A pawn may still move when feet or toes are missing, but becomes incapacitated when a leg is destroyed or missing. Movement is also reduced by ailments including dementia and frailty. Movement is reduced by certain clothing including jackets and parkas.

Manipulation

Manipulation is a pawn's capacity to handle a weapon or tool. It is a factor of a pawn's shooting accuracy as well as nearly every work stat of a colonist. Manipulation is reduced by injured or missing arms, hands, or fingers, or legs of quadrapeds. It is also reduced by ailments including bad back and frailty. Manipulation is modified by prosthetics including power claws, scyther blades, prosthetic arms, and bionic arms.

Talking

Talking is a human's capacity of speech. It is a factor of all social stats including Diplomatic Gift Impact, Recruit Prisoner Chance, Social Chat Impact, and Trade Price Improvement. Talking capacity is reduced by a damaged or missing jaw by. Dementia also impairs talking.

Eating

Eating is the capacity of biological pawns to consume food and is a major factor of Eating Speed. It is reduced by a damaged jaw. Even when missing a jaw a pawn can still eat, though at a reduced rate. A damaged or missing jaw can be replaced with a denture.

Breathing

Breathing is is a function of biological pawns. It is impaired by damaged lungs. A pawn missing a lung has breathing reduced by 50% but can still survive. A pawn that loses all breathing will die. Lungs can harvested and transplanted from other humans.

Blood Filtration

Blood filtration is the function that fights off various diseases. It is a major factor of Immunity Gain Speed. It is impaired by damaged kidneys. A pawn missing a kidney has blood filtration reduced by 50% but can still survive. A pawn that loses all blood filtration will die. Kidneys can harvested and transplanted from other humans.

Health Tab

All creatures will contain a tab when selected called health. This tab will display the bodily systems the creature contains and its current effectiveness. For all of the various creatures within the game, the bodily systems may differ based on what that creature is and what it would need to live in real life (if it could exist, that is). Displayed here is also the current injuries, the effect this has, and the creature's bleeding rate. Do note that not all creatures, most notably the mechanoids, have a bleeding rate that can be displayed here. This tab can also display any currently designated medical operations and any that can be designated. Operations can only be applied to your colonists or their prisoners.


Cold and Heat Injuries

hypothermia: Needs Description
frostbite: Needs Description
heatstroke: Needs Description
burns: Needs Description

Treatment

For most injuries, you can treat colonists with or without medicine (with typically better results if a medicinal substance is provided), and also have them lay in hospital beds or any other bed or sleeping spot assigned as a medical spot, though Hospital Beds further improve the chance of them being treated properly.

Improper Treatment

Treating an injury poorly may result in scarring, reduced healing rate or infections

Operations

Under the Health tab, you can assign an operation to a colonist by clicking on the bill sub-tab. Operations cannot be performed without a proper Medkit to apply an anesthetic.

Transplants

For missing internal organs, either a donor organ can be used or an artificial part.

Limb Replacement

From peg legs to bionic arms, you could either replace a colonists' missing limbs, augment them, or cruelly punish your enemies with peg legs out of spite. Bionic parts have a bonus to specific actions or movement. For example, a bionic leg will increase your colonist's moving speed by 20%. Having a second bionic leg will increase the speed further by 20%, so having both right and left bionic legs will increase the speed by 40%.
