I’ve mostly been running with Ray of Frost (12 AP version) and Blizzard (either cheap or big, depending on how I feel), Force Weapon (15% version), Force Armor, with Diamond Skin (Crystal) and Teleport (Fracture) to stay alive. I use Cold Blooded, Glass Cannon and Astral Presence with those.
It’s effective, but I get sick of Blizzard Kiting. So I am now trying something different:
Celestial Orb, Arcane Hydra, Crystal Skin, Sparkflint Familiar, Force Weapon, Prismatic Armor. Blur, Glass Cannon, Astral Presence.
It pretty much melts faces, and my tooltip DPS is up to 46k with the Sparkflint. The Orbs one-shot nearly all white mobs (and seeing them mow down groups never gets old), Arcane Hydra is great virtually free DPS that happens while I am running around. I’m running around with a total of 86% physical mitigation, and I am very survivable in Act 1.
I always had assumed that Venom Hydra wouldn’t work on Belial, since A) he’s not standing on any actual ground, B) he uses a lot of poison himself, and C) it would be OP given he’s imobile, and it would make sense to make it not work on him anyway (see A and B).
I’m thinking about squeezing Archon in, since I’m geared enough to plow through Act 1 now, and that seems to be the main use for the ability (plowing through content you out-gear). I always used to like Disintegrate back in earlier difficulties, so maybe the Archon version will be viable here. I can probably drop Diamond Skin TBH, so I’ll give it a go.
I prefer to use ultra-offensive builds when I can get away with it. I mostly prefer more defensive ones for progression, though.
