Thanks for the replies! My group doens't play with errata. I spoke with my DM about it though. He said even through the fluff mentions divine, the descriptive text for the feat doesn't so it will work with Arcane spells.
Awesome.
Abjurant Champion + Arcane Preparation
CAr lets you cast Greater Luminous Armor
BoED, which provides a +8 armor bonus and a -4 penalty to attack rolls made against you. Since it's abjuration, Abjurant Champion applies and it really gives a +13 armor bonus, equal to Full-Plate if that penalty is ignored but a 0 arcane failure chance. Not to mention Swift casting +9 AC from the Shield spell. I'd drop Spellsword, replacing it with a single feat to obtain a better bonus without have to spend money.
And pumping Charisma is made of win for you. Saves, extra spells, spell DCs, grab some Slippers of Battle Dancing to attack (and/or dmg? brain fart). Some tips for a high score:
- Snowsong & Nixie's Grace: As arcane spells you can UMD access to them and cast them off a Runestaff, Extended versions last 20mins/cl or around 9 hours @cl20. +8 Enhancement & +4 Moral.
- Rightous Aura: 4th level Paladin spell so you don't need to UMD a wand of this, lasts 1/hr per CL. +4 Sacred.
- Greater Visage of the Deity: Use the domain access sub in CC, gives flight and stuff. +2 Untyped.
- Horseshoes of Flame: Nail them to your hooves for a boost, tidbits of knowledge, horses don't have hands but can wear gloves and Shapechange alters your form. +6 Untyped.
- Command: There is no less than three armor enhancements calling them selves this and they are all different, both in costs and bonuses. DotF's version gives a bonus to your Charisma it's self, ask your DM about it. +4 Competence.
Which is up to +28 Charisma if you used them all. After Level/Tome/Base18 that's 56 (+23)
It's been highlighted by the Sage separate turning pools are separate turning pools. Shroudcrown is a rather expensive but obtainable means to gain another set of Turn Undead, or 3+ChaMod uses to power DMM. With Sacred's Turn Undead and the mentioned ChaMod, 52 uses per day before items and feats, or enough for 7 spells.
