Yeah, I think BoEF and GUCK feats, spells, etc are okay to use.
For half-drow, hmmm. Maybe treat it just like a half-elf, with Arcane Talent (a 0-level sorcerer/wizard spell 3/day, DC 10+Cha) as a bonus feat instead of Skill Focus. Or we could make it three 0-level spells once/day each (Detect magic, Dancing lights, and Mage hand, or something?). The levitation and stuff is getting a little into the more powerful noble drow.
I don't want to just slap you down on this. Kate has a cool custom race, but I've tried to keep disadvantages balanced against it as well.
Okay, shall we say the story starts on Wednesday? Get your stuff done and posted, but if you're late, I guess you just show up late. Shall I find a way to wrangle all your characters into working together myself?
