Crackling Aura

Crackling Aura is a passive talent, loosely resembling the classic Thunder Storm spell and Storm Armor.

In-game
The damage of the Aura is dynamic (changing with the Sorceress's own stats), but additional points will only reduce the interval between strikes. It always chooses a random foe within the standard cast range (same as most other spells), with no control over which one will be hit. It only affects a single target.

Lightning damage done by the Aura can critically hit and does benefit from most other talents:
