|This material is published under the OGL| Dust of
Disappearance: This dust looks just like dust of appearance and
is typically stored in the same manner. A creature or object
touched by it becomes invisible (as greater invisibility).
Normal vision can’t see dusted creatures or objects, nor can
they be detected by magical means, including see invisibility or
invisibility purge. Dust of appearance, however, does reveal
people and objects made invisible by dust of disappearance.
Other factors, such as sound and smell, also allow possible
detection.
