I can't kill Behlial solo in act 2, and I can't get past Ghom in Act 3.
I've tried the standard glass build with ~39k dps but that didn't work.
I've also tried tanking build with LOH. Currently my stats as follows:
-600 All resists
-50k hp I think
I still can't kill Ghom. I can sort of face tank him for a while with Shadow Power and Prep, but then once I run out of discipline (only 40 disc) it all goes downhill. I don't have the lasting power to facetank his farts that seems to stack on top of me if I don't move.
I'm getting really frustrated with the game. Any advice will be appreciated.
