Scroll Shield (Sp): You can form a mobile barrier of hardened paper around you. It hovers in a circle and attempts to protect you from harm. Activating and dismissing this ability is a standard action. You receive a +2 shield bonus to AC. At 5th-level and every 5 levels thereafter, this bonus increases by 1. A successful attack roll against you disperses the shield. You can reform the barrier as a standard action; otherwise, it reforms itself 1d4+1 rounds after dispersion. You must be a wizard of the paper school to select this discovery.
