I have a lot of armor and a lot of resist. I will set the game to monster power 5 and go to act 3 and stand in plagued desecrator all day. I can usually face tank hulking phasebeasts and 1 or 2 arcane beams is no problem.
But... molten just melts me and it seems to be half the time it's not so bad and the other half I see my life drop really fast.
Anyone else experience this? Working as intended?
