This magic attribute allows the user to create and manipulate mirrors of various shapes, sizes, and utility at will. In order to use it to its full potential, specific spells are required, which are stored within grimoires.
The mirrors can be used for two-way communication, to reflect and weaponize rays of light, to create mirror duplicates of a desired person, and to move instantaneously between mirrors.
Since the mirrors reflect light, Mirror Magic could be considered a natural counter to Light Magic. Mirror Magic also struggles with Gel Magic, which refracts light, and Dark Magic, which absorbs light.
