lady Z - Sorc - For the act 2 boss, have your merc get in there for a distraction, and the minions will come out a few at a time - take them out with whatever is most effective for you. Then go in when he is alone (of course you are totally stocked on potions, and rejuvenation is INSTANT, unlike the red juice that takes a few seconds to go up) and do your lightening if that is what you are proficient with.
Alternatives are if you want fire or ice, look for a staff that has those abilities for sale... great boost there. Whatever he uses the most of (I forget at the moment, but I believe it is fire) boost your resistance with an amulet or ring - you can make them in your cube with a combination of gems and jewelry.
