Well, after gaining more info about knowledge devotion, I kinda liked the idea of stacking that and dark knowledge for a gish-like character. Thing is, I'm not too good at the gish part. What I'd be looking at would be having many turn pools to draw from and persist many buffs, along with using knowledge devo and dark knowledge for better hitting power.
All in all, the idea I have goes like this:
Archivist 5/Holt Warden 2/Cloistered Cleric 1(Could ge gotten earlier, tough)/Binder 1/Anima Mage 10/Dread Necro 1
Not entirely sure about races, but with two domains that grant turn pools, holt warden's rebuke plants, and both dread necro's rebuke undead and the cleric's turn undead, that'd be 5 pools. With 16 CHA and improved turning, that makes 50 turn undead attempts, and with tenebrous handling us one turn per persist, that makes 10 persisted spells.
I've in mind using Anyspell and Greater Anyspell to persist wraithstrike and thunder lance, along with bite of the werebear and some kind of polymorph into a stronger form, humanoid most likely. Then, divine power, as my BAB would be down the drain, and still, 5 spells to persist away. I'm not too sure if I should count bard spells or not, but there's also this option, and that's not even accounting for extended persisted spells. That'd bring us to quite a big amount more.
"Core" feats would be academic priest, extend spell, persist spell, DMM:Persist, improved binding, improved turning. Knowledge devotion would be there, but I plan on swapping the cloistered cleric's knowledge domain for that. Able learner could be useful, too. Or a dragonwrought kobold.
I'll be having power attack from bite of the werebear, so that's also out. Some charging feats, maybe?
And then there's also another vestige to bind, as I'd have two of them, and I'm planning just on Tenebrous.
Of course, I'd be using the divine adaptation of anima mage. Also, if there is another PrC that could go well instead of it, I'd love to hear your opinions.
All in all, should have some extreme cheese potential but I don't plan on using all of that. I'd use polymorph for the stats, but not for extra spellcasting, as an example.
If the feats allow, I plan on taking the mother cyst feat, too. And maybe greater visage of the deity is also a good spell to persist. He'd be neutral, tough.
