Dust of Forgetfulness (Magic Dust)

This dust looks exactly like other magical dust, and is stored and delivered in the same manner. When thrown at a character or other living creature, the dust causes the victim to forget everything that has happened in the last hour (including having the dust tossed at him or her). Enemies encountered during that time will be forgotten, paths explored look unfamiliar, and newly made friends are viewed with suspicion. If a character's immediate surroundings are similar to those the character was in an hour before, the victim won't even be aware of the difference without close examination (if any differences in environment exist). After one-week, lost memories are restored-no experience is lost.
Player characters, if sprinkled with dust, should be forbidden by the DM to use “forgotten” knowledge. No saving throw is given against this power.
