Earthen Prosthetic

This spell creates an earthen prosthetic limb to replace one that was removed. This limb full dexterity and controlled as a normal limb despite being made of rock and other earth debris. These artificial limbs have no special or magical enhancements beyond their ability to move based on their holder's will. Because the limb is not flesh and blood, it can be used for blocking attacks; if the prosthesis is an arm and it's not carrying or holding anything, your AC increases by 1.
