Trap

A trap is a type of active skill that throws a device that is triggered by proximity to produce an effect such as immobilizing the enemy, delivering a spell payload, or launching a volley of arrows.

Mechanics

When a character uses a trap skill, he throws the trap to the target location. Characters have a base trap throwing speed of 0.5 seconds.^[1]

Once a thrown trap lands on the ground it must arm itself before it can be triggered.

While armed, a trap can be triggered by an enemy entering its trigger radius. Characters have a base trap trigger radius of 10.^[2] Trap trigger radius is affected by trap trigger area of effect modifiers. Trap trigger radius is not affected by skill area of effect modifiers.

Traps remain armed for a limited duration, after which they expire. Trap duration is specific to each trap skill. Most traps are triggered automatically when they expire, regardless of whether there are any enemies nearby. Exceptions include Bear TrapBear TrapTrap, Spell, Duration, Physical

The affected enemy will take increased damage from traps and mines until the debuff expires.

Trap duration is not affected by skill effect duration modifiers. Likewise, trap duration modifiers do not affect the duration of skill effects created by traps.

Armed traps are invisible to enemies.

Traps will be destroyed if they take any damage. Traps cannot be targeted directly, but they are vulnerable to area of effect damage. Traps cannot be damaged while they are travelling through the air, while they are arming, or while they are triggering. The passive skill, Clever Construction can also prevent traps from being damaged for a number of seconds after being thrown.

There is a limit on the number of traps a character can have out at one time. By default, a character can have 15 traps. Throwing an additional trap that would exceed the trap limit will cause the oldest trap to be destroyed. There are passive skills that can increase the limit.

Trap cooldown

Some traps store limited uses and replenish one use after a cooldown period. A counter is shown on the skill icon which indicates how many uses are currently stored. Trap stocks are stored per skill and not per gem, so equipping multiple of the same skill gem will not allow you to bypass its maximum stored usage limit or cooldown time.

Targeting

When a trap is triggered by an enemy, it will use the skill at the enemy that triggered it. If a trap is not triggered by an enemy (either the trap duration expires or triggered by other means, such as Chain Reaction) or there are no enemies within the mine trigger radius, it will target its current location. If the skill is a forward-firing projectile, it will fire it in a random direction.

Interaction with player stats and support gems

Traps and mines act much like totems in that when they cast their payload, it is the trap/mine that casts the skill, not the player. This means:

Leeching: Players cannot leech health or mana via traps. The trap/mine is actually doing the leeching, but they self-destruct after they're triggered, so leeching has no practical effect.^[3]
Damage reflection: Damage is reflected back to the traps/mines and not the player, so they are safe to use on damage reflecting monsters, maps, or PvP targets.
Trigger gems: Traps and mines (and totems) will not work with "Cast on..." trigger gems, even if the trap/mine has a "Spell" type gem tag/keyword; the player places or throws the trap/mine, but the trap/mine is doing the actual spell-casting.
