Anyway, things are working pretty well. I’m trying the Fiend version now. I’m not sure if I should put it on devastation or aether corruption. Earth Eruption has Acid spray, which I feel is more important to use there. Arcane bomb is on AAR (those might switch once Acid spray is maxed).
For the record, this isn’t exactly a lightning build. I never converted any Aether. I just turned the fire into lightning, which makes it easier to gear, as I only need to focus on 2 damage types instead of 3. It just so happens that once fire turns into lightning, lightning does more damage than Aether.
