Afterimage Gem

This crystal clear prism contains a small cavity. When you use an action to point the prism at a creature or object, you cause an image of that creature or object to appear within the gem's cavity. At a later time, you can place the gem as an action to cause the image within to appear as if you had cast the [spell]major image[/spell] spell, which will remain until dispelled or the gem is moved.
