A shocking arc of lightning reaches from the caster to a targeted enemy and chains to other enemies. Each time the arc chains from an enemy, it will do so simultaneously to two further enemies, but never to enemies that have already been hit by any of these chains. Also grants a buff making your Arc damage lucky for a short duration.

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.

Version history

VersionChanges
3.14.0
  • No longer causes Modifiers to Buff Duration to also apply to this Skill's Soul Gain Prevention.
  • Now has a Cast Time of 0.7 seconds (previously 0.8).
  • Now has a Soul Gain Prevention duration of 2 seconds (previously 6).
  • Vaal Skill Gems can now only be obtained from a set of specific methods such as Corrupting Gems, Vaal Side Areas, Divination Cards (that specifically grant Vaal Skill Gems) and the Lapidary Lens in the Temple of Atzoatl.
  • 3.3.0
  • Previously chained +40 times.
  • Now deals 38-64 lightning damage at gem level 1 (up from 2-35), up to 924-1539 lightning damage at gem level 20 (up from 49-939)
  • Now requires 25 souls per use (down from 32).
  • Now deals 15% more damage for each remaining chain.
  • Now increases shock duration by 100%.
  • Now increases the effect of shock by 100%.
  • Now chains 5 times, but each chain can split to another enemy (from which it can also chain). This number grows as it levels.
  • Now causes your Arc damage to be lucky for 4 seconds.
  • Now has an added damage effectiveness of 180% (up from 80%).
  • Now prevents you from gaining Vaal souls for 4 seconds after use.
  • 2.0.0
  • Now has 100% chance to Shock (up from 10%). Now gains 1.5% increased Shock Duration per Quality.
  • 1.1.2
  • Arc and Vaal Arc have had their damage increased by 60%. Arc and Vaal Arc can now no longer chain back to the same target immediately, but must now bounce one more time.
  • 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).
  • 1.1.0
