A dueling shield is a heavy shield with long, piercing spikes at each end, allowing it to be wielded as a weapon. It is a two-handed exotic double weapon. While wielding a dueling shield, you gain a +2 shield bonus to AC, and may attack with it normally. However, in any round when you use the Power Attack feat, you lose the shield bonus from the dueling shield. You also lose the bonus to AC if you are flatfooted, or otherwise denied your Dexterity modifier to AC. While a dueling shield can be enchanted as a magic weapon or shield, each piercing end must be enchanted separately, as must the shield itself.
