Spectro-illusion

This ability was an illusion conjured through Sith magic. The sorcerer would manipulate rays of light within his reach and altered them to transform into any physical illusion the caster may choose. The spell could allow the user to trick enemies into thinking the caster was invisible, or that the area was crowded with dangerous creatures while in reality it was merely an alteration of the otherwise empty location. Because the ability was an alteration of the environment and not the mind, it was extremely difficult to detect.
