i tried getting to him tonight.when i came to some named that was a see invis Ogre.i WAS lvl 81 and he conned LB,so i decided to kill him.when he got to about 20% health,he used a knock back spell and threw me into some big pit thing,where i took a 200k fall dmg and died and also lost my lvl :(
so be careful what named mobs you do attack here
