Weapons Mastery
I finally got around to looking up the actual rules governing the weapons mastery asterisk that appears on character sheets over one or more weapons, and basically iy kind of mimics spell selection. Each day the player chooses which weapon that they're masters of, that day. In other words it's stoopid with all the O's. We'll keep playing it the way that we're playing it, any weapon with which you're proficient grants you the mastery property.
