IED smoke trap

A pair of smoke shells connected to a trigger which detonates on touch or bullet impact. Since it is hidden in the surrounding terrain, it cannot be placed adjacent to other traps. Animals can sense these when calm.

The IED smoke trap are landmines that explodes into a cloud of non-damaging blind smoke when tripped.

Acquisition

IED smoke traps can be constructed once the Ieds research project has been completed. They require Smoke shell 2 Smoke shells, 1,400 ticks (23.33 secs) of work, and a Construction skill of 3.

Summary

Traps are single use security buildings that may be triggered when a pawn of any kind walks over it.

  • The base trigger chance is 100% for enemies, including mechanoids and animals affected by the manhunter mental state. Note that despite the name, animals currently hunting a human pawn for food are not "manhunters" and are not considered enemies.
  • Non-manhunting wild animals have a 25% chance to trigger the trap.
  • Colonists and tame animals have 0.4% (one in 250) chance to trigger the trap.[Friendly Mechanoids?]
  • Friendly visitors and their animals, as well as revenantsContent added by the Anomaly DLC and sightstealersContent added by the Anomaly DLC will never trigger a trap.[Invisibility in general?]

However, colonists and non-manhunting animals are aware of the location of traps, and will avoid pathing over them if reasonably practical.[Path Cost?] One notable exception is roped animals being dragged by a handler - the rope limits their movement, overriding their usual behavior.

Prisoners are considered to be their original faction for the purposes of traps. Enemy who you have taken prisoner will retain their 100% trap trigger rate and will ignore traps when pathfinding. Colonists that you have taken prisoner retain their 0.4% trap trigger rate, even during a prison break, and will avoid traps whenever possible.

In all instances, the nimble trait multiplies the trigger chance for that pawn by 10%, that is, a 10% chance for enemies and 0.04% chance for friendly pawns.
IEDs can also be triggered when hit by a projectile dealing the Bullet, Arrow, or ArrowHighVelocity damage type, or when damaged below 20% of their maximum HP.

When triggered, the trap will begin to spark and emit a hissing sound for 15 ticks (0.25 secs) before exploding, creating a cloud of blind smoke damage in a 8.6-tile radius.[Verify Radius] The explosion and resulting cloud deal no damage but reduces the accuracy of ranged attacks through it by 70% and prevents turrets, both friendly and enemy, from targeting pawns in or behind it. The cloud dissipates after approximately 30 seconds.

Non-drafted pawns will attempt to run from an activated IED trap, even if it wouldn't affect them.[Verify]
