Did this guy about 2 weeks ago. Had around 10 people, average level probably around 65ish. The adds spawn VERY fast... like one every 4-5 seconds so be prepared for that. He wiped everyone except a necro that had hit FD. We managed to take out the host right before we wiped. I ran back from pok and said "What about the demise?" to Aakstaff and voila! He gave me the book. Not too hard of an encounter, he hits for 1150ish.
