Choose one type of shield: buckler, light, heavy, or tower. You are more skilled at keeping the shield's weight from interfering with you movement.

Prerequisite(s): Proficiency with selected shield.

Benefit: While wielding the selected shield, the armor check penalty applied to your skills as a result of that shield is reduced by 1. This reduction stacks with that granted by a masterwork shield, but cannot reduce the total armor check penalty below 0. You may ready a shield for which you have learned Shield Focus as a free action. These benefits apply both to standard shields and to shields made of special materials, such as mithral or darkwood.

Special: You may take this feat multiple times; its effects do not stack. Each time you select this feat applies to a different shield type.
