So after talking it over with Kunoichi... I'm starting to have a solid character concept in mind now, and I thought I should run it by everyone here before going ahead with the sheet. My idea was to play a monavic deva, a former servant of a goddess of love and beauty, whose lustful personality distracted her and her fellow celestials from their duties until her behavior finally became to much even for the goddess. She was cast out, and suddenly free from the responsibilities that had been restraining her, started dreaming of becoming a goddess herself. I'm thinking that she was well on her way to ascending to divinity as a goddess of sex, with worship of her spreading like wildfire across the world, until the gods, jealous and more than a little worried, conspired to have her sealed away.
Mechanically, I was thinking that her martial path would be Battle Dancer (basically a Charisma-based Chaotic Monk) with a little of a Chaotic non-spellcasting Paladin, if I can do that. Her magic path would be a Bard using Perform (Sexual Techniques), if I can get away with that... prestige classes to be determined, but there seem to be a lot of options. Her monster path would be Radiant Monavic Deva, with the template's Radiant Attack refluffed to represent her dazzling beauty. While I assume she wouldn't start out with divine ranks, I'm hoping that she could acquire worshippers and gain ranks during the game.
And I think I'll need permission to use the Battle Dancer... I believe it's in the Dragon Magazine Compendium. If I can use it, I'm hoping it could also use the house rules for the Monk, with any Wisdom-based abilities swapped for Charisma, which is the class's main ability score.
