At 5th level, a shield champion can throw a shield so it ricochets off her target (and possibly other solid objects) to return to her at the end of her turn. This ability functions whether or not the shield champion hits her opponent or moves on her turn. The shield deals no damage to targets it bounces off, other than the original target of the shield champion's attack. Certain circumstances can prevent the shield from returning to the shield champion, such as an opponent using a readied action to catch the shield, or the shield sticking to a mimic's adhesive. The shield champion can opt to not have a thrown shield return to her, in which case it falls to the ground as it normally would. If the shield has the returning ranged weapon special ability, she can use either that or this ability.
If a shield champion has additional attacks from a high base attack bonus, these additional attacks can be ricochets off an earlier target. The distance to each additional target counts toward the total range of the shield, and range penalties apply, but there are no additional penalties for attacking in this manner. Because ricocheting attacks are treated as separate attacks, effects and modifiers that apply to only one attack roll (such as true strike) apply to only the first attack and not to the others. A shield champion can throw a shield as part of a brawler's flurry.
At 9th level, a shield champion gains Greater Shield Focus as a bonus feat. She must meet the prerequisites before taking that feat. At 12th level, a shield champion can use her unarmed strike damage when dealing damage with a shield (whether in melee or as a thrown weapon) or the shield's damage, whichever is greater. At 17th level, by ricocheting her shield off a nearby surface before hitting her intended target, she can treat that surface as the origin square of the attack to determine whether the target is flanked and whether the target gains a cover bonus to its AC. She can use this ability to attack a creature with total concealment from her if she knows what square it occupies, but the attack still has a 50% miss chance. This ability replaces brawler's strike.
