Stormtrance

Stormtrance is the Arc Super of the Warlock Stormcaller subclass. The Warlock gathers Arc energy and releases it as a continuous lightning stream at a targeted enemy; the lightning then spreads to nearby enemies, so it can clear large groups quickly. Lightbearer Wizards from the Lucent Brood can also use it.

Upgrades

Three options are available: a shockwave that repels and damages nearby enemies, chain lightning with twice the range, or short-distance teleportation.

Origin

Warlocks learned the ability by watching the Vex try to harness Arc storms on Mars. It debuted in The Taken King and returned in The Witch Queen. Crown of Tempests is an Exotic helmet that works with it.
