The Dark Eye of Unvisibility has the power to (as hinted by its name, but never actually demonstrated) make anyone invisible. While normally not exceptional (as certain beings can turn invisible), Master Eon states that if Nightshade successfully stole it, he would use its powers to steal everything, thus implying that the invisibility granted by the eye surpasses natural invisibility.
Trivia[]
During the intro cutscene of the Midnight Museum, Buzz erroneously refers to the Dark Eye of Unvisibility as the "Dark Eye of Mañana", and later on, he refers to it as the "Dark Eye of Tomorrow".
