Fighters can be many things, from soldiers to criminal enforcers. Some see adventure as a way to get rich, while others use their skills to protect the innocent. Fighters have the best all-around fighting capabilities of the PC classes, and they are trained to use all standard weapons and armor. A fighter's rigorous martial training grants them many bonus feats as they progress, and high-level fighters have access to special melee maneuvers and exotic weapons not available to any other character.
Fighters gain the Armor Specialization feat at Fighter levels 3, 6, and 9. For more details, see Feats: Armor Specialization.
