− | + | Spike traps are single use traps that may be triggered when a pawn of any kind walks over it. The base trigger chance is 100% for enemies, including animals affected by the [[Mental break#Manhunter|manhunter]] mental state. Non-manhunting wild animals have a 25% chance to trigger the trap but are aware of the location of traps and will avoid pathing over them if reasonably possible. Colonists, friends, and tame animals have 0.4% (one in 250) to trigger the trap, but are also aware of the location of traps and will avoid pathing over them if reasonably possible. In all instances, the [[Traits#Nimble|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. | |
− | + | When triggered, the spike trap makes five attacks against the pawn that triggered it. Each attack does [[Damage Type#Stab|Stab]] damage. The amount of damage dealt by each attack is determined by the following equation: | |

− | + | The damage can be fatal to humans or large animals if it is made of good materials. The base damage varies according to the material it was built from. The damage type is sharp melee, which strikes mainly on the head and torso and usually causes bleeding. The spike trap should be built out of stone or metal, as wood has a low damage output. Although stone spike traps take large amounts of time to make, they can kill a [[raider]] in one trap. See [[Defense structures#Spike traps|Defense structures (Spike Traps)]] and [[Defense structures#Entryways|Defense structures (Entryways)]] for more information. | |
