I wasn't trying to attack your work, my friend; my remake is different, but not necessarily better. Normally, my comment would have been worded with more finesse, but I'm sick and have been for two days (this coupled with very little sleep) so my normal command of English is somewhat on the wane.

One small nitpicky thing: technically, even though it is perfectly okay for us to use the rules for the "Mettle" ability, "Mettle" isn't actually OGL, so we shouldn't use the name. WotC might get...touchy.
