Protective (Quality)

Protective weapons provide a shield bonus to AC if you do not attack with the hand wielding them. When you attack with the protective weapon, the shield bonus is lost until the start of your next turn. The amount of shield bonus granted by a protective weapon is normally 1, but can be greater (see weapon's description for details). Note that protective weapons CAN be used to perform a Shield Bash combat maneuver without losing their AC bonus or any shield enhancements and properties, but they do not add anything to-hit or damage for that combat maneuver. Protective weapons can also be enchanted with both melee weapon enhancements and properties, as well as shield enhancements and properties. Which property applies in a round depends upon the usage of the object (attack or defense.)
