Weapon and Armor Proficiency: A shield champion is proficient with all simple weapons and with shields as weapons. She is also proficient with light armor, and with bucklers, light shields, and heavy shields. This replaces the brawler's weapon and armor proficiencies.
Brawler's Cunning (Ex): If the brawler's Intelligence score is less than 13, it counts as 13 for the purpose of meeting the prerequisites of combat feats.
Martial Flexibility (Ex): A brawler can take a move action to gain the benefit of a combat feat she doesn't possess. This effect lasts for 1 minute. The brawler must meet all the feat's prerequisites. She may use this ability a number of times per day equal to 3 + 1/2 her brawler level (minimum 1). The brawler can use this ability again before the duration expires in order to replace the previous combat feat with another choice. If a combat feat has a daily use limitation (such as Stunning Fist), any uses of that combat feat while using this ability count toward that feat's daily limit.
Unarmed Strike: At 1st level, a brawler gains Improved Unarmed Strike as a bonus feat. A brawler may attack with fists, elbows, knees, and feet. This means that a brawler may make unarmed strikes with her hands full. A brawler applies her full Strength modifier (not half ) on damage rolls for all her unarmed strikes.
Usually, a brawler's unarmed strikes deal lethal damage, but she can choose to deal nonlethal damage instead with no penalty on her attack roll. She has the same choice to deal lethal or nonlethal damage while grappling.
A brawler's unarmed strike is treated as both a manufactured weapon and a natural weapon for the purpose of spells and effects that modify either manufactured weapons or natural weapons.
