Dust of Forgery (5e Equipment)

Wondrous item, uncommon

Found in a small bag, this dust resembles very fine sand. There are 1d4 + 1 pinches of dust within the bag (the dust emits an aura of illusion magic). A creature can use an action to sprinkle a pinch of dust on a piece of parchment, or something used to write on. The object then becomes under the effect of the illusory script spell as if the creature had cast it. A creature can use a bonus action to speak the command word and undo the dust's effect without destroying the previous words that were written. (The command word is sewn into the side of the bag, however, a creature may not realize that the word is the command word).
