Never mind, I just went and killed the bastard. Actually, once you learn to dodge the lightning he sends out periodically, its so easy! One just stands at the back, and keep spawning wolves at his feet! while he's occupied with them, just blast him with cold. As he picks off a wolf just keep spawning another and just chug that mana potion! He didn't even remove one health from me! The bad news though is that i'm now onto the next act which means you're way behind again.
