Dust of Disappearance

There is enough dust for one use. 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.
