New creature in Summer Update 2008. It can be asumed that he is an Elven Vampire due to the fact he says "Ashari", shoots sniper arrows and dwells in Hellgate, which is extremely close to Ab'dendriel.
Damage Taken From Elements
Spawns with 0-2 vampires, Goes Invisible and runs away in low health.
Beware if you are low level, because this boss will be fatal for you.
Higher level Mages should run, heal when he paralyzes you and shoot Flame Strike and GFBs when he goes invisible, so you hurt summoned vampires and boss at the same time and get him visible again.
