Caustic Arrow
Lua error in Module:Item2/core at line 500: The "class_id" parameter is required..
Borrowing a bit of toxic chemistry from the secretive Oriath Necromancers guild, a skilled archer infuses their arrowhead with a wicked venom. Once enchanted, the arrow will explode violently when it impacts a target, showering both foes and the surrounding area with a cloud of choking death. Anything living caught in the cloud will suffocate quickly, suffering heavy chaos damage until they move far away.
Description on the official Path of Exile website [1]
Caustic Arrow is a bow attack that fires an arrow dealing chaos damage and exploding in a caustic cloud. Enemies standing within it receive a debuff that deals chaos damage over time. The caustic cloud does not poison and is therefore not affected by poison-related modifiers.
Skill functions and interactions
- Caustic Arrow will explode either at the targeted location or on the first monster or obstacle it hits.
- Multiple projectiles: additional projectiles added will cause additional caustic clouds, but debuffs from multiple clouds do not stack.
- Piercing: piercing Caustic Arrow projectiles will cause additional clouds each time they hit and will receive the chaos damage bonus any time they impact an enemy.
- Projectile damage: passive nodes and gems (such as Slower Projectiles SupportSlower Projectiles SupportSupport, Projectile
