I remember seeing this mob over 10 years ago. Cool that the undead version has been added. He looks like an undead gnoll if i am not mistaken. I still think he looks cool. If you are wondering where he spawns it is in south karana. In the small graveyard area not too far from the bridge if you were just coming from North Karana. It is over the first hill. You should see some other undead in the area if its not camped. EDIT: I was going by memory. You will find much more detailed information if you click the Aegis of Life link and read one of the top posts.
