71 bard. sing DA song, aggro him and his friends. run back into the maze corridor and mez him when he catches up, then lead his friends back out to 4c and fade when they all catch up. then run back in.
he's not resistant at all, but he does proc often. i had to mez and regen twice during the fight but eventually got him. he dropped the axe and two daggers.
i think a 71 pally could do this - keep him stunned and yourself healed.
