Carapace

This spell brings into existence a visible and opaque hemispherical wall of force similar to a carapace of certain animals, like a turtle or armadillo. This spell is similar to a Shield spell in certain respects. The carapace intercepts attacks, providing three-quarters cover, though it does not move out of the way when you attack, providing the same cover to your enemies (and making this spell not as useful as a shield in that respect). You designate half the battlefield as being blocked by the carapace and you can change the defensive orientation of the carapace as a free action on your turn. The carapace is otherwise considered a Wall of Force, though it may be damaged by weapons of +3 or greater enchantment and can take 50 points of damage before being destroyed. Gaze attacks cannot penetrate the carapace.
