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. It is other than 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 Support inventory icon.pngSlower Projectiles SupportSlower Projectiles SupportSupport, Projectile

  • Point Blank: Point Blank does not affect the caustic cloud damage, it only affects projectile attack damage.[3]
  • Iron Grip: The strength bonus from the Iron Grip keystone passive does not affect the caustic cloud damage because the cloud is not considered an attack nor is it based on physical damage.

  • Accuracy: The projectile attack is subject to accuracy and can miss. However, the explosion will create a caustic cloud and do damage regardless of whether the projectile attack hit or missed. Piercing Caustic Arrow will not create additional clouds if missed.
  • Duration: modifiers to duration will affect the duration of the caustic cloud.
