Skill functions and interactions

  • Can't be evaded: Vaal Caustic Arrow ignores accuracy and evasion rating for hit chance calculations.
  • Unlike Caustic Arrow, Vaal Caustic Arrow attacks horizontally and is not ground targeted. It also pierces all enemies.
  • An enemy can only be affected by one caustic ground effect but if multiple are applied, the strongest effect will be the one that applies to the enemy.

Will Vaal Caustic Arrow's ground effects stack with regular Caustic Arrow?

An enemy can only be affected by one caustic ground effect but if multiple are applied, the strongest effect will be the one that applies to the enemy (i.e. the Vaal Caustic Arrow effect takes priority).
