Chain Lightning

Chain Lightning is the melee ability of the Arc Warlock Stormcaller subclass, in the Attunement of Conduction tree. It is an extended-range melee that jolts the target and chains lightning to nearby enemies. While amplified, it creates an additional set of chains.

Patch history

Update 2.2.1 reworked it so it can chain up to five times, up from one, and each target can be hit twice. Chain damage was lowered from 50 to 31 per hit in that update. In 2.8.0 chain damage was reduced again, from 31 to 27. Chaining Arc damage also reduces the cooldown of the Arc Web grenade. Later patches may have changed these numbers.
