You better hope the sorc is lighting and cold, then you better hope the sorc is not super super godly. Very godly you still got a chance to beat him. Then wear 2x raven forst rings, Luna, Lightsarbe, and the ammy that absorb lighting forgot wut's the name. Then just lock on him with charge, and you shall be win, it's going take some time. My pally always have aborb gear in the stash for sorc, also too bad aborb don't work on hydra, if you see a hydra sorc, you doom.
