Dust of Disappearance

When you use an action to throw the dust into
the air, you and each creature and object within
10 feet of you become Invisible for 2d4 minutes.
The duration is the same for all subjects, and
the dust is consumed when its magic takes effect.
If a creature affected by the dust attacks or casts
a spell, the Invisibility ends for that creature.
Great for pranks, theft and finding out what your
friends really think of you
