I'm saving the Angurvadal for my Assassin->Fighter. 5 stars in Long Sword, Critical Hit on 19 or 20, Poisoned Septuple Backstab with 25 STR from my Draw Upon Holy Might....and ToB will only add things like Greater Whirlwind on top of this. And against Undead, I've got Daystar in my other Quick Weapon for a quick Sunray. Ooohhh, baby.
(I'm going to be going to the Underdark very soon.....shouldn't things like Sunray, False Dawn, & Sol's Searing Orb destroy adamantine?)
