meh I think you can just do it with the ol open wounds merc setup trick, its just a little tougher since you need infinity for damage here unlike the other uber chars
I tested a bit and yeah you can do it but I wouldn't call it a good ubering build. I mean, you're fighting 75% resist mephisto and 78% resist diablo/baal. All 3 regen without merc ow, and 95% resist on the latter two if merc is dead
totally reliant on that merc ow and keeping it alive and I was using toothrow + kiras in a desperate bid to survive conviction aura
