Arcane CL of 20 (18th casting)[/spoiler]
You should have plenty of feats available to snag all the usual Dragoon antics, and
heroics and
mirror nove for any you're missing. Three feats will get you persistent buffs, and one polymorph will massively add to your repertoire of maneuvers (valkyrie). Use that giant block of feats at the beginning to snag prerequisites (I recommend Power Attack from Overwhelming Force style for the ranger fighting style), being sure to use Martial Wizard. Proceed to buff up and own face as a perfect maneuverability diving nuke, or sit back and fill the enemy full of arrows with that sick skirmish damage that will apply to anything with arcane ability (which at high level gesault is everything), or play GOD, with two different spell lists and extra swift actions. Oh, and good luck sneaking up, thanks to both persistent Foresight and Mindsight. Combining some of those healing maneuvers with a dragoon strike would be pretty sweet too, as your IL will easily be high enough to snag the best maneuvers that Shadow Hand, Devoted Spirit, and White Raven have to offer (I think those are the main three an RKV gets...), and if nothing else, they are observable, so a valid target for
mirror move. If you want more raw power, I'll adapt my Ultimate Mage for gesault...but be ready for DMG dodging.
