Mirror image

Mirror image allows the caster to bring several illusions of him or herself into being in the caster's immediate surroundings. The images behave and look exactly like the caster, and the caster is able to merge with, or split from, any of the images at will. If an image is struck, such as with a weapon, it disappears for good.

Notably, the Cormyrean state sword Ilbratha allows its wielder to cast mirror image on him or herself (and the sword) once per day.
