Goblin Chemist of JJ works. Byceps spam for a lot of piety, health to get hits in on bigger guys, wheytwut for finishing them off. Ding to refill both bars if you regen fight, and to fill up the "missing" piety from higher level kills. It works quite well, I ought to try it somewhere difficult. On demand XP padding also saves blackspace. Haven't even tried it prepped up properly, should be pretty nuts with either fire heart or crystal ball, and very silly with Dragonsoul also (anyone try that with the Bycepss spam?). On a non-difficult dungeon you don't need to regen-fight at all.
Even had 2 nice runs in hard Gaan'Telet with it, missplayed myself to death both times at the boss fight. It's strange, mind you, because I kinda never got anywhere with JJ in there ^^ Obv not a great choice, especially the way I played it but it was fun
