Dust of Disappearance

This shimmering dust is usually found in a small vial that contains enough for a single use. You can use an action to scatter the dust into the air, covering you and each creature and object within 10 feet and rendering them _invisible_ for 2d4 minutes. This consumes the dust. If an affected creature casts a spell or attacks, the effect ends for that creature.
