Caustic Arrow /6
A projectile attack that creates a patch of caustic ground on hit which deals chaos damage over time to affected enemies.Name | Show Full Descriptions |
---|---|
Pierce Support | Allows projectiles from Caustic Arrow to travel through more enemies, creating multiple patches of caustic ground, dealing damage to more enemies simultaneously. |
Lesser Multiple Projectiles Support | Increases 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 Support | When 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 Support | Greatly increases both the physical damage from hits and chaos damage over time component of Caustic Arrow. |
Swift Affliction Support | Decreases the duration of Caustic Arrow's ground effect, but compensates for this by increasing damage over time dealt. |
Void Manipulation Support | Grants 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. |
