Pain is a pawn capacity: How much pain a person feels.
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. 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 20%.
Most pain is temporary, but scars and certain diseases can cause long-term pain. A painstopper implant will get rid of all a colonist's pain and negate any pain-related mood penalties. Note that colonists with the Masochist trait get a mood bonus from pain instead of a penalty, so it's usually better to leave them alone.
Pain follows a somewhat complex formula:
- This is 1.0 for humans.
- This is also 1.0 for humans
Extra pain is determined by individual injuries:
Extra Pain = Injury Damage × Injury Pain Value
- 50 crush damage would do 50 damage × 1.25 crush pain = 62.5 extra pain
- 50 burn damage would do 50 damage × 1.875 burn pain = 93.75 extra pain
