Dust of Disappearance

Found in a small vial, this powder resembles very
fine sand. There is enough of it 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 1 minute. 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.
