Fire Trap

Fire Trap throws a trap that explodes when triggered, leaving an area of burning ground that damages enemies who walk through it.

Skill Functions and Interactions

Burning Ground Effect: The burning area left behind after a Fire Trap explosion does not act like other burning damage. It will do fire-based health degeneration damage simultaneously with other burning damage for as long as an enemy is within the radius of the Fire Trap. Once an enemy leaves the area, they will stop taking damage from Fire Trap. Trap, fire, area and elemental damage passives will increase the damage of both the initial explosion and the damage over time. Burning damage passives will only increase the DoT. Spell damage passives will only increase the initial damage.

Duration: Skill duration passives and the gem will increase both the time before the trap times out and the duration of the burning ground effect.
