Not to play the role of combo breaker here but I need a name to a book and I figured I'd just hijack this so someone could share it.
The book is part of a three-long series (maybe more) on a planet with liquid magical power. A guy from a church carries such in a vial I think, anyway he joins up with some kind of long living dark wizard outcast and they do some stuff. The BBEG turns out to be some kind of mental vampire demon or w/e that gets beaten by not thinking about him.
I know I'm super vague here, been a long time since I've read it. Anyone have any idea what I'm talking about?
