I think he said it -700 or something sick like that.
I actually think it broke -1000 with Corim.
Caoliac only had -700 to -800 on account of lower DEX.
And yes, a melee class with that kind of AC is truly sickening.
(I honestly don't remember the numbers, and all my logs got lost when I reformatted) 
I remember how much of a beast Tylith was...shiver good thing we were allies.
Heh.
I remember on Morticant, at first, before he figured out what he was doing, he was my malform fodder. Then, slowly, as he started to (I also gave a hand by not full-saccing his stuff/holy weapons out of pity, something which I later kicked myself for), it got harder and harder.
By the end of Morticant's life, Corim was hands-down slapping the hell out of me.
Stupid 1k AC crusaders.
