I'm rebuilding most of the NPCs from my Pathfinder campaign (the adventures not the rules), and I wanted to see if anyone had any insights. The one I'm working on now is the BBEG of the first adventure.
The idea is she's an Aasimar who was in foster care of a priest most of her life. She accidentally got pregnant and miscarried a horribly difigured baby, which, along with some other magical help, drove her off the deep end. She now swears allegiance to the Goddess of monsters and wants to destroy her hometown as an offering to be transformed into a demon.
The group is 6 PCs who will be level 3-4 (hopefully 4) when they fight her. Her build in the book is Fighter 2/Cleric 3, using buffs on herself to fight with a bastard sword (I'm probably changing that to a greatsword, especially since she doesn't have a shield). I'd like to stay close to that, but would certainly be willing to change it if I had a good reason. The domains available from the deity are Chaos, Evil, Madness, Strength, and Trickery (yeah, I know they suck).
