I have run right by him with no issues every time. I even made it by him and the necro boss standing on the same bridge on my last run.
He doesn't always cast Iron Mist; when he does, you'll understand.
Bring a sword and sub Sever Artery for Power Attack; you'll be surprised how much faster that makes things. I always use DB first, if that doesn't cause bleeding, I follow it up with Sever. If you're inclined to stick with axes, Dismember or Executioner's Strike would fare well also. Nothing against Power Attack, but there are skills which do more added damage or cause useful conditions. Desperation Blow is awesome, but only half its conditions are useful. Crippling and Weakness don't mean jack on an Ice Imp, obviously, so guaranteed bleeding or deep wound helps ease their transition out of the mortal coil.
