Pollution stimulus is a beneficial hediff that is granted to insectoids and pawns with the Pollution stimulus gene when on polluted terrain.

Stages[edit]

Stage Begins at Symptoms
Pollution stimulus (minor) ≥0%
Pollution stimulus (moderate) ≥20%
Pollution stimulus (maximum) ≥50%

Progression[edit]

Every 60 ticks (1 sec), an insectoid or pawn with the gene will increase in stimulus severity by +3.33% if on polluted terrain, or −0.3% if on unpolluted terrain.

Threshold range Real time since 0% severity[1] Game time since 0% severity[2] Real time in state[3] Game time in state[4] Real time since 100% severity[5] Game time since 100% severity[6]
None 0% - - - - 20,000 ticks (5.56 mins) 8 in-game hours
Pollution stimulus (minor) 1% - 19% 18.02 ticks (0.3 secs) 0.01 in-game hours 3,600 ticks (1 min) 1.44 in-game hours 16,200 ticks (4.5 mins) 6.48 in-game hours
Pollution stimulus (moderate) 20% - 49% 360.36 ticks (6.01 secs) 0.14 in-game hours 5,800 ticks (1.61 mins) 2.32 in-game hours 10,200 ticks (2.83 mins) 4.08 in-game hours
Pollution stimulus (maximum) 50% - 100% 900.9 ticks (15.02 secs) 0.36 in-game hours 10,000 ticks (2.78 mins) 4 in-game hours - -
Pollution stimulus (maximum) 100% 1,801.8 ticks (30.03 secs) 0.72 in-game hours - - - -
  1. Real time spent before entering the state, assuming severity is increasing and the starting severity is 0%
  2. Game time spent before entering the state, assuming severity is increasing and the starting severity is 0%
  3. Real time spent in the state before crossing the lower threshold, assuming severity is decreasing from higher threshold
  4. Game time spent in the state before crossing the lower threshold, assuming severity is decreasing from higher threshold
  5. Real time spent before entering the state, assuming severity is decreasing and the starting severity is 100%
  6. Game time spent before entering the state, assuming severity is decreasing and the starting severity is 100%

Analysis[edit]

Severity increase is very rapid compared to its depletion. A single hour spent in polluted terrain will keep a pawn in the maximum tier for 4 hours, in addition to any extra time spent on the polluted tile itself. This means that relatively little polluted terrain is needed to maintain the bonuses. Place some under where a pawn will regularly spend a few hours a day. Dining rooms and under workstation chairs are ideal at pawns will regularly visit them, but they risk exposing pawns that are sensitive to, and/or do not benefit from, pollution. Bedrooms and meditation spots are decent substitutes if not every colonist has the gene however the impact will typically wear off before they refresh it if the pawn is on a monophasic sleep schedule.
