I am ru nning it with my pally 3 shaman and mage. So far it has not dropped. I figured out the trick to that first boss. Space out your guys and use fire elementals too. If the shadow thing spawns under your guys strafe left or right.. Make sure they are spaced out enough that you dont strafe your other toon into the spawn. Until I figured out how to do that I was wiping on that guy cause he would keep spawning that shadow deal under my team.
