I found the easiest build is having a Vampire Cursed toon. The resistance goes a long way when you get to later levels(especially ice). After that just put two points to strength and two points to stamina. The Vampire's ability heals you based on a percentage of the physical damage you do, so you want weapons with the highest damage output. I quit at level 30 and could pull multiple rooms with out any trouble. Hope this helps!
