Dust of Disappearance

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 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.
Now you see me...
