@dragonwriter- let me look into those two PrC's. As long as their nothing like the binder you are playing in the Savage tide, they might be ok.
Oh, they're quite different from Sharazek.
Pact Bound Adept is for taking advantage of the dragonpact rules from Dragon Magic (and is Sorcerer only).
Basically, the Sorcerer magically contacts a dragon of a given color and makes a deal. The dragon sacrifices some HP and gains a spell slot of a particular level. The Sorcerer gives up his spell slot and gains a special set of SLAs, depending on the dragon's color. They don't even have to be together and the Sorcerer may never know exactly what dragon made the deal with him (but the dragon knows just who the Sorcerer is).
The Pact-Bound Adept is just better at making the deal and gets some extra goodies from their pact (like being able to give up a lesser spell slot).
Wyrm Wizards focus more on learning about how the dragons use their innate magics. It gets a few boosts to metamagic (three spells get free metamagic adjustments, of varying levels) and learns a few spells for free, from any list (not many).
Like I said, if they are too much trouble, I can do something else.
Oh, and are the Alternate Class Features from PHB2 and Unearthed Arcana alright with you? I like some of the stuff for Conjurers and Necromancers, if I go Wizard, and the Metamagic Specialist one in PHB2 for Sorcerers is also very nice.
Obviously, I'm not completely settled on class yet, let alone race... Just narrowing ideas down.
