Level 89 Hybrid Crit Ice Nova of Deep Freeze Hierophant [3.23] (pobb.in)

This is my only 4th char; I'm not using any guides. Still looking for a good body armor to replace Ghostwrithe with. But at least this build freezelocks 17M hp map bosses. I might try Elemental Proliferation Support because sometimes projectile mobs still can snipe me from beyond the screen.

I have Frostbolt because I switch to Ice Nova of Frostbolts when I need extra DPS and I know exactly where the monsters are (I do that for expeditions, for example). But mapping, delving, etc. with Ice Nova of Deep Freeze is just much faster and easier.
