Caustic Arrow /6

A projectile attack that creates a patch of caustic ground on hit which deals chaos damage over time to affected enemies.
NameShow Full Descriptions
Pierce SupportAllows projectiles from Caustic Arrow to travel through more enemies, creating multiple patches of caustic ground, dealing damage to more enemies simultaneously.
Lesser Multiple Projectiles SupportIncreases the amount of arrows Caustic Arrow fires, allowing it to cover a larger area by creating multiple patches of caustic ground at once. At later levels, obtain the Greater Multiple Projectiles Support gem to affect enemies in a larger area.
Mirage Archer SupportWhen Caustic Arrow hits an enemy, an apparition is created above you that fires a copy of Caustic Arrow at enemies, at a reduced rate and with less damage.
Vicious Projectiles SupportGreatly increases both the physical damage from hits and chaos damage over time component of Caustic Arrow.
Swift Affliction SupportDecreases the duration of Caustic Arrow's ground effect, but compensates for this by increasing damage over time dealt.
Void Manipulation SupportGrants more chaos damage but lowers the elemental damage of Caustic Arrow. The Caustic ground effect only deals chaos damage, so Void Manipulation gives more damage at no drawback.

Caustic Arrow


Caustic Arrow is a bow attack that fires an arrow dealing chaos damage and spreading caustic ground. Enemies standing within it receive a debuff that deals chaos damage over time. Caustic ground 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: firing additional projectiles can spread caustic ground over a wider area, but the damage over time from overlapping patches of caustic ground does not stack.

  • Piercing: piercing Caustic Arrow projectiles will spread caustic ground 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 SlowerProjectilesSlower Projectiles Support) that increase projectile damage will increase both the damage on hit and the area of effect damage.

  • Concentrated Effect: ConcentratedAOEConcentrated Effect Support decreases the size of the AoE and increase its damage. However, due to the nature of the skill and the wording of its modifiers, the damage increase will not appear on the tooltip.

  • Point Blank: Point Blank does not affect the damage from caustic ground; it only affects projectile attack damage.[2]

  • Iron Grip: The strength bonus from the Iron Grip keystone passive does not affect the damage from caustic ground because it is not considered an attack nor is it based on physical damage. The increased projectile damage portion of the IronGripIron Grip Support will increase the damage from caustic ground, but the strength bonus the support gem shares with the keystone will not apply.

  • Accuracy: The projectile attack is subject to accuracy and can miss. However, the explosion will spread caustic ground and do damage regardless of whether the projectile attack hits or misses. Piercing Caustic Arrow will not spread caustic ground if it misses.

  • Duration: modifiers to duration will affect the duration of the caustic ground.

  • Culling strike: The increased damage from CullingStrikeCulling Strike Support applies to the damage from caustic ground, but the caustic ground will not kill enemies instantly when they have less than 10% life.

  • Curses: ProjectileWeaknessSniper's Mark requires the target to be hit. The caustic ground won't be affected by it.DespairDespair does affect the caustic ground.
