If you want easy mode, Sorcerer. Cast holy affinity on yourself and use the archstaff's charge attack over and over again. If you want to be more active than that, Strider or Assassin. A lot of people say Mystic Knight but I didn't like it since you can't control what your magic cannon bolts target.

If you're playing DD2 (why) then I liked Warfarer with daggers and a bow the most
