Imperceptibility or Incorporeality is the ability to sheathe one's body in psychic energy, which in turn makes the user unable to be detected by the senses. This aura is not the same for every faculty, and it may induce any of the following effects: * Invisibility * Intangibility * Inaudibility * Insipidity * Inodorosity * Entire Imperceptibility * Selective Imperceptibility * Mechanical Imperceptibility * Catoptric Imperceptibility * Telesthetic Imperceptibility
