Caustic Arrow

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.

Poison Arrow is a ranged attack skill that fires an arrow dealing chaos damage and exploding in a cloud of poison.

Skill Functions and Interactions

Poison Arrow creates a poison cloud, which poisons enemies standing within it.

Duration: Skill Duration supports and passives will increase the duration of the poison cloud.

Explosive Projectile: Poison Arrow will explode either at the specified location or on the first monster or obstacle encountered. If it hits an enemy, it will deal additional chaos damage based on your weapon damage. Wherever it explodes, it will leave a poison cloud that causes a debuff.

Multiple Projectiles: Additional projectiles added will cause additional poison clouds, but multiple clouds will not cause additional debuffs.

Piercing: Piercing Poison Arrow Projectiles will cause additional clouds each time they hit and will receive the chaos damage bonus any time they impact an enemy, but multiple clouds will not cause additional debuffs.

Ranged Attack Totem: Poison Arrow works with ranged attacks totem since patch 1.0.2.

Projectile Damage: Passive nodes and gems (such as Slower Projectiles) that increase projectile damage will increase both the damage on hit and the area of effect damage.

Concentrated Effect: Concentrated Effect will decrease 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 poison cloud damage, it only affects projectile attack damage.

Accuracy: The projectile attack is subject to accuracy and can miss, however the explosion will create poison cloud and do damage regardless of whether the projectile attack hit or missed. Piercing poison arrow will not create additional clouds if it miss.
