| − | + | IEDs 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. 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) to trigger the trap. | ||
| + | * Friendly visitors will never trigger a trap. | ||
| − | + | However, colonists and non-manhunting animals are aware of the location of traps, and will avoid pathing over them if reasonably 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. | |
| − | + | When tripped, IED traps will start emitting a hissing sound, hinting enemies to run away. | |
| + | |||
| + | They explode in a 3.9-tile radius, 0.25 seconds after being triggered, dealing 50 [[Damage types#Bomb|Bomb damage]], having a fair chance to incapacitate and a small chance to kill a pawn. | ||

Placement requires some forethought by guessing positions where the enemies will be stuck for a couple of seconds such as cover spots (rocks or walls) and choke points on the side where enemies would take cover when engaging your colonists. Example: an IED trap surrounded by a tile or two of [[sandbags]] will explode while victims are still close due to the reduced movement speed to walk out over them. | Placement requires some forethought by guessing positions where the enemies will be stuck for a couple of seconds such as cover spots (rocks or walls) and choke points on the side where enemies would take cover when engaging your colonists.

| − | + | IED traps can be triggered by shooting at them, so they can be placed near other [[high-explosive shell]]s to make a bigger explosion, to destroy [[crashed ship parts]] for example. | |
| − | + | [[File:Bombing a defoliator.png|center|400px]] | |
| − | + | Here, a dozen of high-explosive shells are placed near a [[Crashed ship parts#Defoliator ship|defoliator ship]] (1200 HP), along with an IED trap. | |
It requires a bit of micro-management to place individual stacks of shells (make the shell at a [[machining table]], carry it to a 1×1 [[stockpile zone]], delete this zone to avoid having more shells on it, repeat), and a careful placement of the trap (placing it too close to a mecha will wake it up), but the explosion will destroy the defoliator outright. The pawn shooting at the IED trap should be ready to run very fast, or better: wear a [[jump pack]]{{RoyaltyIcon}} to avoid being sliced up by the waking mechas. | It requires a bit of micro-management to place individual stacks of shells (make the shell at a [[machining table]], carry it to a 1×1 [[stockpile zone]], delete this zone to avoid having more shells on it, repeat), and a careful placement of the trap (placing it too close to a mecha will wake it up), but the explosion will destroy the defoliator outright.

| + | Unfortunately, a stack of 12 shells doesn't make the same damage as 12 stacks of one, so individual stacks have to be made (in fact, a stack of 25 shells exploding brings the defoliator to 725/1200, not even half the damage for more than twice the amount of shells). | ||
This technique works well to destroy ship parts, or possibly sleeping [[scyther]]s that accompany it, but killing [[centipede]]s would require much more shells and is clearly not the best method: kiting them is much easier. | This technique works well to destroy ship parts, or possibly sleeping [[scyther]]s that accompany it, but killing [[centipede]]s would require much more shells and is clearly not the best method: kiting them is much easier. | ||
