IED incendiary trap

A pair of incendiary 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 incendiary trap is a trap that sets pawns on fire.

Acquisition

IED incendiary traps can be constructed once the Ieds research project has been completed. They require  2 Incendiary 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 revenants and sightstealers 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, dealing 10 Flame damage in a 3.9-tile radius and potentially igniting flammable pawns, buildings, and flooring in the area. For a full list of effects, see Flame.

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

Analysis

IED incendiary traps can be a highly effective crowd control measure when used in conjunction with non-flammable barricades or walls, and a straw matting floor. They can be shot to create a wall of fire igniting melee attackers. Enemies on fire will run around wildly and not attack.

They are also a good tool to capture enemy raiders or kill infestations. They can be used in an enclosed room to quickly increase the temperature inducing heatstroke on raiders and insects alike.
