      Vaal Arc

      Vaal Arc is a vaal spell that launches a chaining lightning arc at the target that lasts until no valid target remains or all chains are used up.

      Skill Functions and Interactions

      Although Vaal Arc chains, it is similar to Arc in that it's not a projectile and therefore does not benefit from projectile-specific modifiers on gear, passives and skill gems.

    • 1.1.0d
    • Vaal Skill soul counts were initially balanced for Merciless difficulty, where there are more monsters. We want them to be easier to use in Normal and Cruel difficulty. We have halved the number of souls required for each skill. In Cruel difficulty, skills require 50% more souls to uses. In Merciless difficulty, they require 100% more (which is the same as before the patch).
