Trap Support

For the game mechanic, see Traps and Mines.

Trap is a support gem. When this gem is linked to a skill gem, it alters the skill so that instead of the player casting the skill directly, the player lays a trap. The trap is invisible to enemies, and the first enemy to enter the trap's trigger radius sets off the trap. That enemy is targeted by the linked skill, and the trap is destroyed.

Skill functions and interactions

When Trap is linked in combination with the and or gems, the result is a skill that lays a mine. When the mine is detonated, it lays a trap. When the trap is sprung, it casts a totem, which then can cast the linked skill. Players cannot create traps that lay mines, or totems that lay mines or traps.

Trap will affect a linked attack skill if that skill is ranged. Attacks such as Frenzy and Elemental Hit, which normally operate with ranged or melee weapons, will only be affected by trap if the player has a ranged weapon equipped.

For more information about traps, see traps and mines.

Cooldown: The gem overrides the cooldown on supported skills with the trap cooldown. For example when the support gem is combined with Cold Snap it can be used multiple times in a row, as long as there are trap charges remaining.

Spell Echo: A spell supported by cannot also be supported by . The gem combination will not result in a spell trap that repeats its cast.
