Solo'd this guy alot now - all i ever see him drop are blood points and obthingy sword - the lore rogue one that procs dooming darkness. Cant pronounce the Obul or whatever word.
Havent seen the truncheon yet though, and ive done south west and north wings alot 8(.
It spawns in north & west wing and a 62 druid could easily single pull it out of the room it is in, root it, dot it down and go away happy with sub-par loot.
