Lightbending

Invisibility
Invisibility is the most well-known spell in the sub-school of lightbending. Through invisibility, a caster is able to warp their physical form, in such a way that light particles pass through their body. By doing so, they effectively become invisible. This invisibility is total, and does not leave any refractions or 'shimmers' that other spells do, and is often as such regarded as 'true invisibility'.

Mirror Images
Mirror Images function in much the opposite way that invisibility does. Instead of allowing light particles to pass through a physical object, you cause a barrier to exist in a location, that causes light particles to bounce off of it in such a way that it causes an image identical to the caster, or another object. It is almost always a 'mirror' image, because it is far easier to replicate the image of something in the immediate vicinity of the caster.
