Was looking for some more information in the Hole as usual, came across this photo from Everlore.com on wayback machine that shows what his spawn location should be:

My laptop has taken a nose dive so I apologize for not being able to log into game and give you a precise loc but he is looking outwards in front of the door that leads down to the crypt that houses the Fallen Erudites and Dartain the Lost. He currently spawns on top of the crypt at the back of the courtyard and facing the opposite direction.
Notice that he is not shown wielding the Tainted Darksteel Sword. I'm not sure if this would enable quadding on P99 or not, making it a tougher fight? Other post from his everlore main page lists some attack data saying he only doubles for 220 max, not sure what his max is on P99.
Main page of everlore with comments on max hit and double attacking (also mentions he barely casts, on P99 he seems to cast often, may lead to an easier fight with him casting so much and not double attacking + bash):

One final comment is his picture doesn't show him with a pet either, but the post mentions he had a weak one (just like on P99). Possible someone was tracking him and took screenshot on pop, before he casted a pet. Or perhaps classic EQ varied what spells were loaded on spawn and he didn't have his pet loaded? dunno.
Obviously this is a minor tweak, but the Hole is my favorite zone so working on making it as much of a mirror image as possible on P99!
