I'm having a lot of trouble with the Ancient Vampire in the magic shop basement. I can knock down his health bar to (apparently) zero without much trouble, but can't finish him off. I'm having the wizard memorize lots of spells that don't allow a reflex save (e.g. isaac's lesser missile storm, magic missle, etc), since he seems to have improved evasion. The cleric is casting as much divine damage magic as she can. But while I can hold him off for a long time, I can't ever seem to kill him. I just keep damaging him indefinitely until I run out of spells, and then it's a war of attrition that he wins because of his regeneration.
My 2H ranger is admittedly not doing much damage because his weapons are only +1's, and the rogue is also ineffective b/c he's undead (no sneak attack). I might try again tonight and bring the barbarian in addition to the fighter, as his axe should cut through the damage reduction.
In any case, I just wanted to verify that I didn't miss something that is actually making him impossible to kill, like a switch or trick or somesuch. Or, is there a nonviolent solution I haven't figured out? I tried having both the wizard dispell the force field, as well as doing the alchemy route to extinguish the braziers. I can't get out of the basement once in to alert the authorities, because he bars me in. I can always skip and come back later, of course.
Thanks, sorry if I'm being stupid. Just frustrated.
