I've got a fifteenth level character that I'm playing in a friend's game.
The spread is Cleric 5/Church Inquisitor 8/Contemplative 2, and she's built to be a melee cleric (Divine Power, Divine Favor, Spikes, Brambles, etc.) due to our party's lack of, well, melee.
She has the Law, Travel, Inquisition, and Celerity domains.
I hit fifteenth level and have a feat to throw around. I don't have my character sheet with me, but I'm pretty sure her feat list is as follows:
Extend Spell, Persistent Spell, Divine Metamagic (Persistent Spell), Extra Turning, Domain Spontaneity (Travel), Weapon Focus (Rapier), Ancestral Relic. I have one other feats (due to having two flaws), but I honestly can't remember what it is(she's human).
She's lawful evil (The alignment restrictions for Church Inquisitor and Ancestral Relic were rule zero'd with some GM adjudication and background development) and has an ironwood rapier as a weapon, and also has a buckler equipped.
Anyway, I'm looking for a suggestion for a good fifteenth level feat. Our GM is pretty flexible with anything from any source so long as it's justifiable in game (i.e. I don't just magically develop some broken combat ability) and he can actually read the original source, so feel free to name unofficial sources as well (although we all have a preference for 'official' material, since between all of us we probably have the sourcebook in question). She's got a 12 Dexterity and a 12 Intelligence, so Dodge, TWF, and Combat Expertise (which I was considering) are all lost causes (at least until 18th level once if I blow my 16th level attribute point to bump one of these to 13).
Further information is available upon request, as I'm sure there's a crucial detail I'm forgetting.
