Weapon Skills

Each weapon has weapon skills, as shown in the weapon table. Weapon skills are only usable by creatures (including NPCs) who have proficiency with the weapon they are using. A creature can only use one Weapon skill each turn, and can only use each of their weapon’s skills once per encounter.
