Out of curiosity, why are you doing dice rolls instead of point buy? I'm a fan of point buy since it puts everyone on equal footing to start off.

I have an idea for a character that would fit fairly well into this- a lizardman voodoo witchdoctor (just a cleric mechanically, though I've got some voodoo-themed custom spells that I'd like to run by you). Only thing is that lizardfolk tend to not be available in a level one start- would it be possible for me to join the party after they gain a few levels so that I don't unbalance things?

Edit: actually, found this, would this be an acceptable racial breakdown for playing a Lizardfolk?
