He basically seems to do a loop around the buildings in the south end of the zone, near the spell turn-in NPC. Was green at level 67, waited for him to path near the zone wall, pulled with nullify magic to avoid summoning, sent in my 67 necro pet, threw on a couple of DoTs and FD-ed. He died pretty fast: pet could probably have soloed him.
Of course I wanted the sword for my Ranger alt and he dropped the wand. Grr.
