He drops a decent shaman spear 2hp (the one he is holding in the picture above). Took him down with a group consisting of 59 war, 57 rog, 55 cleric, 57 sha, 56 pal. He is very magic resistant. He is also unstunable. I nailed him with bash and my force stun spell and he just kept running. Be warned that he does like to gate and it almost impossible to stop him from doing so. Make sure you have the camp cleared before you pull him and you wont have a problem.
2 full groups from my guild tried to take this guy down. All the people were 50 and up and we did not kill him. He summons and has a very bad AoE poison based or based nuke I think. He killed a ranger and a pally in 2 casts of this AoE, very nasty. Resisted most spells with Tash on him. Resisted my nukes, DoTs, slowing spells, str debuffs... When and if you attept to kill him be sure to have about 4 casters dispell him first then attack.
