You sprinkle the object with a handful of gem dust, and the last words of your spell fade like they are being dragged into a hole. Then the normal sounds of the world reestablish themselves, but the spell within is set to be unleashed later.

When you touch the object and give the command word you designate, the object becomes the subject of a silence spell. The effect of the silence spell moves with the object and lasts for 6 rounds.
