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 Slower Projectiles SupportSlower Projectiles SupportSupport, Projectile

3.12.0	Now has alternative quality: Anomalous 1% chance to inflict Withered on Hit (per 1% quality) Divergent 1% of Physical Damage Converted to Chaos Damage (per 1% quality)
3.9.0	Now deals 8.8 base Chaos Damage per second at gem level 1 (from 7), up to 1927.1 at gem level 20 (from 1714.8). Now gains additional radius as the gem levels, up to +6 at gem level 20 (from +3).

3.0.0	Caustic Arrow's damage over time grows more quickly as it levels, up to 765 base Chaos damage per second at gem level 20 (up from 550.3). It is also now modified by projectile damage modifiers.
2.6.0	Caustic Arrow gains 1 additional unit of radius every 5 levels. No longer gain increased area of effect radius.
2.1.0	Poison Arrow has been renamed to Caustic Arrow as part of the poison changes. The damage of this skill has been increased by around 37% at level 1, but reduced by around 42% by level 20.

2.0.0	Reduced the mana cost across all levels. Now grants 0.5% increased area of effect radius per 1% of quality (was 1% per 1% quality). Damage increased by approximately 26% at gem level 20.

0.9.13	It now starts off around 85% stronger at level 1 and is about 1% weaker at level 15.

0.9.9	The size of the Poison Arrow clouds now scale with their Area of Effect radius properly.
0.9.7	Improved the effects of Poison Arrow.
0.9.5g	Fixed a bug where the Poison Arrow cloud would appear where you clicked even if the arrow was stopped before then by a wall.
0.9.5	Fixed Poison Arrow so that damage from the degeneration is scaled properly for PvP.
0.9.4	Increased the damage.
0.9.2	Poison Arrow does more damage at higher levels than before.
0.8.7	Poison Arrow does additional chaos damage on the actual arrow itself now, in addition to the cloud damage.
0.8.5	Added new skill prototype: "Poison Arrow" (Fires an arrow which explodes in a cloud of poison. Enemies who enter the cloud are poisoned for a short time, taking chaos damage)
