Some warriors have a background in hand-to-hand martial arts, some train in them on the side. These fighters tend to exhibit stronger discipline than most, and are capable of blending their fist techniques with their weapon techniques.
Class Skills: A disciplined fighter's class skills are Acrobatics (Dex), Climb (Str), Craft (Int), Diplomacy (Cha), Handle Animal (Cha), Heal (Wis), Knowledge (history) (Int), Knowledge (nature) (Int), Perception (Wis), Profession (Wis), Ride (Dex), Sense Motive (Wis), and Swim (Wis). These replace the standard fighter class skills.
Improved Unarmed Strike: Disciplined fighters gain Improved Unarmed Strike as a bonus feat at 1st level. This ability replaces the fighter bonus feat received at 1st level.
Martial Art (Ex): At 2nd level, a disciplined fighter selects one of the following feats as a bonus feat: Elemental Fist, Perfect Strike, Punishing Kick, Serene Touch, and Stunning Fist. A disciplined fighter need not have any of the prerequisites normally required for these feats to select them. A discipline fighter's levels count as monk levels for determining the daily uses of these feats. This ability replaces the fighter bonus feats received at 2nd and 6th levels.
Style Blending (Ex): At 10th level, a disciplined fighter may use the feat he received at second level in conjunction with any weapon, not just unarmed strikes and monk weapons. The disciplined fighter may retrain Improved Unarmed Strike if he likes, replacing it with any combat feat for which he qualifies, despite the fact that it is a prerequisite for the feat he receives at 2nd level. This ability replaces the fighter bonus feat received at 10th level.
