The magician heals a damaged structure made primarily of stone, wood or metal.   Tightly grasping a small piece of the damaged structure, the magician whispers to the universe and heals 6d4 damage + magician's proficiency bonus in damage to the structure.   This does not restore magical properties of an object or create a duplicate of an existing object, but does restore structural integrity including AC, damage reduction and vibrancy of the object.
