If i remember correct he hit for about 3k. The only thing special about him is that he called for help from local mobs in the nearby building when he was at about 50%. If you are able to pull him out to about Trakanon area the adds wont come. He was partially slowale, didnt test to see if he was snarable. *Edit* he also dropped Skull of Commander Koth... don't know what it is used for yet.
