Saw him get his booty kicked by a lvl 44 monk in Field of Bone. He hides in a room at the end of a tunnel off the northwest corner of the FoB zone; the tunnel entrance is on the beach.
Monk that killed him let me loot his head, which is as the above stats describe - no drop, magic, lore item.
Yup, I owned him twice today. 43 chanter, have my pet get in and start hitting him, and fear him, he runs away, with a few pathing lapses which lets me get in a few nukes, usually gets to the oracle down the beach a bit. He's cake.
