By using this magic, a mage can render an object unnoticed, even if it rests in plain view. Observers’ gazes simply pass over the item in question.
This spell bestows the effects of the Incognito Presence spell upon an object equal to or smaller in Size than the lowest of the mage’s Matter, Mind or Gnosis scores. As with Incognito Presence, any kind of attention-grabbing activity undertaken with the object in question (or by one openly possessing the item) automatically terminates the effects of this spell.
Mysterium Rote: The Purloined Letter
Scholars of the Mysterium don’t always have sufficient time to carefully secret away their acquisitions. This spell enables such a willworker to conceal an object without really hiding it at all.
