I'm not sure I understand what your trouble is, but have you consulted some walkthroughs? Why are you unable to get through the Claw Viper temple -- I'm assuming that's what you're referring to? If it's because of the difficulty, I guess I won't be able to offer much help, as I played as a necromancer. (And farmed quite a bit of XP, which meant in that act, doing that quest, my character's level was over twenty.)
