Shell of Stone

Shell of stone enfolds the caster in a thick carapace of stone, granting a significant bonus to his armor class. It is more difficult to shatter the knee of someone so encased. Weapons colliding with this carapace have a chance to break from the impact, those which slash into the stone being more susceptible. Indestructible weapons are not subject to this.

However, it is a great deal more difficult to move while surrounded by this carapace of stone, significantly increasing movement costs and occasionally delaying the caster when he moves.
