The Storm of Insurrection
A shield guard allows you to use your shield to grant you a bit of DR when bothered by foes. Setting up a shield guard is a move action. You gain DR 1 for a light shield, DR 2 for a heavy shield, DR 3 for a kite shield, or DR 4 for a Tower shield. You take a 2 point penalty to your AC if you choose to use your shield this way.
