Unless there's something I'm overlooking in TOS Core, it shows both wizards and sorcerers hit die as d6 instead of d4. I'm also a yet to play newbie, trying to mess around with a wizard for my first upcoming game, so it's possible that I'm mistaken. Excellent work though it's really quite neat.
EDIT - Nevermind. I was still in the pathfinder rule set. I knew I should have dug around a bit more before posting, lol.
