Dust of Disappearance

Found in the Gingerbread House, 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.
