Quick question: I have to pay the full ECL +3 for half-dragon, right?
Nope. LA will be dealt with via racial bonuses; ie, you'll get less than a LA 0 race.
The Ogre got 3 features, but no the ability bonuses of the standard races - not that he needs any more ability scores. I'll do something similar with the half-dragon.
Which reminds me - what's the other half?
do you have all the form sources that I listed beyond the SRD (MM3, Draconomicon, Lords of Madness)?
Yup. Only ever skimmed over LoM, but I do have it.
Avalon:
Hrm.
You'd be #9 out of 8.
Meaning, you are free to build a character, but someone is going to get left out in the end.
So, if I do have to pick, I'll be looking at concept first, execution (hahaha) second and order of application 3rd.
As for books...
I have... alot. As in, like, 75% of everything WoTC put out since 3.0 that wasn't setting specific, plus a fistfull of Ebberon and FR stuff as well.
After reading over the PrCs: You'd better have some good explanations ready why you keep the rest of us around.
That'll be taken care of IG via your patron.
