The caster crouches down and cuts his flesh with a ritual dagger so that blood drips onto the floor. He closes his eyes and imagines the growth.
The form he imagines grows out of the caster's body. The surface and the appearance are based on the appearance of the archdemon or his servants who are attached to him. The caster can thus create a body part of almost any shape, which can be moved almost at will. The body part can have a length of Power meters.
