Weapon Mastery
Weapon Mastery allows you to deal additional damage with a single type of weapon. You must select this weapon when you take your first rank in Weapon Mastery and cannot change it later. When rolling for damage with your selected weapon, you may add your ranks in Weapon Mastery to the dice pool.
Every 3 ranks (3, 6, 9, etc.), you may select an additional weapon to apply this benefit to.
Warriors automatically apply this bonus to all weapons; they need not select them.
