Phase 1. You'll need to kite adds around the U shape back and forth, I used the templar for the charges. This is just staying alive (don't blow your archon here).
Phase 2. Wherever you are standing stay there, Let belial charge you, drop a blizzard, pop your crystal skin, move right out of melee range so your templar will take a few hits, pop archon. Ignore all damage, pop a potion if needed and just burn. Belial will drop back a bit after a few melee hits and begin casting the 3 bombs. If you do this right, belial should be around 30% after the burn. You'll then need to kite belial and adds, hopefully you don't get too overwhelmed with adds, attempt to focus the electrocute damage on belial and keep blizzards up. You should push to phase 3.
Phase 3. This phase is literally a joke if you do it right, I was dumb at first and didn't realize it, if you see where I'm standing in the above photo, belial's slam attack misses you completely. You will get the occasional hit, if you get two consecutive, you MUST use a potion. Save your crystal skin for the poison blast phase. Stay near the top left (Reason I say this is belial's hit box is huge, i had plenty of wipes on this easy phase because my toon attacked rather than moved). Only pop crystal skin when the bombs get heavy. Only pop archon (off CD) after a poison phase (you don't want to get trapped without crystal).
If you need any further clarification, let me know!
Edit: Nevermind! Finally got her! RNG was by my side

Could you please provide a rough estimate of you stats? I'm working my way through Act II, and want to gauge my readiness for this encounter.
Post the detailed view of your stats via a screen shot if possible.
Thanks
Also congratulations!
