Lightning Trap

For the Vaal-themed counterpart, see Vaal Lightning Trap.

Lightning Trap launches a ring of projectiles through the enemy that set it off, dealing lightning damage to them and subsequent targets.

Skill Functions and Interactions

• Cast speed: Modifiers to Cast speed do not affect Lightning Trap since it is the trap, not the player, that is casting the spell.

• Damage types: Lightning Trap is affected by modifiers to Lightning Damage, Projectile Damage, Spell Damage, and Trap Damage.

• Pierce: Lightning trap does not pierce by default, but it can do so if player has pierce chance from items/passives or it is linked with gem.

• Chain: Lightning trap can chain if linked with gem. Chained projectiles can miss the targets if they are moving too quickly.

• Projectile Speed: Modifiers to Projectile Speed from passives or things like affect the maximum distance each projectile can travel. Higher projectile speed also makes chained projectiles hit more frequently as they won't fly past moving enemies so often.
• Curse on Hit: Lightning Trap does not work with Curse on Hit
