Fighters learn the basics of all combat styles. Every fighter can swing an axe, fence with a rapier, wield a longsword or a greatsword, use a bow, and even trap foes in a net with some degree of skill. Likewise, a fighter is adept with shields and every form of armor. Beyond that basic degree of familiarity, each fighter specializes in a certain style of combat.
