So I'm making a a Dragonfire Adept character for someone who has never played D&D before, starting level 6 with starting gold 20k. Race is going to be human. Flaws are allowed if wanted. Almost all books allowed, if you do reference a non-core feat or item, please give the book or link to the source. Homebrew tentatively allowed.
What feats and magic items would BG recommend I give this character?
I'm thinking of spending all the gold on Con, Cha, and other passive magic enhancement bonuses to keep things effective yet simple, but I'm sure BG can tell me a much better way to blow all that gold.
