crafted light gear. damage is all you need. his nova skill is instakill always. you enter tp, put up new one, spam tstone, die, repeat. go to town immediately when you damage him to stop his healing. if you die before you can get back to town respawn as fast as possible to minimize healing. he's got normal heroic shield plus unique shield that only goes away when he's next to you. you'll see an exclamation point above his head when this happens.
