Sorry for the insane title, I'm a little harried right now. Because of that friggin' Nabassu. Whose name I can't remember...one sec, I'll look it up...Aec'Letec.
Understand that I've played BG2 and its expansion all the way through, so running into this clown whom I just CAN'T SEEM TO BEAT is making me a little stressed. I've attempted this fight 20 times so far, before I went back to my autosave outside of Ulgoth's Beard. Through all of them, I've gotten straight-out rocked, turned into a monster, had party members get ANNHIALATED (i.e. their portrait disappears), and, my personal favorite, I've killed him just to watch one of those statuesque cult guards TURN INTO HIM.
So now I'm coming back with god knows how many potions and buffs. And I buff up. And I go and fight him. And I lose. Reload. I lose. Reload. I lose. Over and over and over...
How do I beat this guy?! Even with a million summons and all his stupid guardians dead, he still ends up owning me. AAAAARGGGGH!!!!
