Looking back over what others are planning, it would seem bedford is going to need a hand on the front-line. I gave some thought to the Anima Mage idea, but I don't want to step on WD's toes with another Sorcerer concept.
So, currently planning melee-focused Binder (Tome of Magic), with possibly a little dabbling in Crusader (Tome of Battle).
A little rules question for you Gandalf, just so I can decide a little better how I will handle the vestiges: If I use the Otiax Air Blast ability (melee touch, reach, 2d6 damage but no STR bonus on damage), can I use Power Attack with it? If I can't PA, can I use Combat Expertise?
If I go this route, I do plan on using Otiax for melee combat, but I can function if you say no on the Power Attack. It was just a thought for pumping damage up a bit, when I use Otiax (which, by the way, would not be an "always" thing, since I would like to change my vestiges every so often).
Currently, the plan for the Binder is using Otiax + Savnok for front-line heavy. I'm thinking a couple levels of Crusader for Thicket of Blades and some other tricks. I might also swap some Binder levels for the Knight of the Sacred Seal PrC, but I'm not sure on that, since it will take one of my vestige slots at all times (more or less).
