A '''spike trap''' is a single-use trap that deals heavy but material-dependent damage to the pawn that triggered it.

== Acquisition == 
Spike traps require {{Required Resources}}, {{ticks|{{P|Work To Make #}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}. Spike traps cannot be placed or constructed directly next to each other nor next to any other kind of [[trap]].

== Summary ==
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, 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. Friendly visitors will never trigger a trap. 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:
{| class="wikitable"
| Damage Per Attack = Trap Melee Damage * Material Sharp Damage Multiplier * rand(0.8, 1.2)/5
|}
Where:
* Damage per Attack is the damage each attack does to the target. A spike trap performs 5 of these attacks when triggered.
* Trap Melee Damage is 100 for spike traps
* Material Sharp Damage Multiplier is a material dependent factor.
* rand(0.8,1.2) is a random factor between 0.8 and 1.2. This random factor is rolled once only and then applied to all attacks, it is not rolled for each attack.

The armor penetration of the attack is determined by the following equation:
{| class="wikitable"
| AP = Damage Per Attack * 0.015
|}
* AP is the armor penetration of each attack.

Note that both the damage and AP of the attack in the info screen are misleading. The damage listed is the average sum of the damage inflicted, the AP is incorrectly calculated as if this damage is all dealt at once.

Once a spike trap is triggered, it is destroyed. The "auto rearm" option, enabled by default, produces a blueprint to replace the trap.

== Analysis == 
{{Stub|section=1}}
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.

-Spike traps are invaluable in the earlygame, as one of the few defense strutures available. A hallway of spike traps can virtually end any frontal [[raid]], short of [[tough]] or [[nimble]] pawns, without your colonists ever seeing combat. A single trap can be fatal to humans or large animals. Multiple traps can fall most creatures, short of [[thrumbo]]s and heavy [[mechanoid]]s. But as raids get bigger, it starts to get impractical to replace the traps.
+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.
-Place traps where you expect raiders to go. Raiders will take the shortest, unobstructed route to a target. Unless they are sappers or breachers, raiders will try and break walls last. Common locations are in the corners of your base, where enemies will likely make turns, as well as narrow areas that receive frequent traffic. If it doesn't seem obvious to you at first, one way to find out is by studying raids that do come.

-Wood spike traps can be quickly created and placed in large quantities. Stone spike traps are cheap to make, and can kill a humanoid [[raider]] in one trap. But given the significantly increased crafting time of both the traps themselves and the stone blocks required to build them, it is often more efficient to simply make several wooden traps. Stone traps are helpful if you're limited by space or type of resource available, and can be a good activity when one has the Work Frenzy [[Mental inspiration]]. Metal traps are even stronger and don't take as much time to make, but are expensive in terms of resources.
