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.
