My girlfriend and I are playing the game together. She's new to the game. On my end, I've tried a few untwinked single player builds and the only one I've been able to finish on was corpse explosion necromancer. I tried barbarian but the damage output was way too low. Same went for zealot. What did work somewhat was a hybrid zealot with holy shock as the source of damage and zeal as the delivery mechanism. That build breezed through normal and nightmare but is stalling in hell and probably will take some grinding to finish with. This then makes me think, would it work if I were to play a frenzy barbarian or pure zealot and have my girlfriend enchant me or would the damage be too low still? BTW, would enchant apply twice to a dual wielding barbarian? If this sort of build wouldn't work, I'd be happy to hear additional 2 player ideas.
