Heath is right, I left it open to being ran either way. Hmm, I didn't think about High Magic Enchanting. I'll go ahead and edit the proposal to specify the prerequisite of Skill +1/Backstab +2/Strength +1 for ease and overall better mechanics balance.
Also, I've made the poll for the stamina table replacements. I know this and the other replacement ideas probably haven't been discussed enough, but we don't want to risk prolonging the release of the new version of the book too much.
