Lvl 39 monk now on NM. Still facerolling through NM since its pretty much impossible to die as a monk. Mantra of Healing when health takes a beating, then serenity + heal, seven side strike for invincibility, and if you absolutely have too, pot. I've used like 4 pots the whole game and have yet to die.
Also using a sword and board with 48% dam reduction, 23% block, 26% dodge.
Come at me Hell!
