Wondrous Item

Legendary Requires Attunement

This crystal ball is about 6 inches in diameter. While touching it, you can cast the scrying spell (save DC 17) with it.
  You can use an action to cast the mage hand spell while you are scrying with the crystal ball, the spectral hand appearing within 30 feet of the spell’s sensor. When cast in this way you can make the spectral hand invisible. When the scrying ends, so does the spell, and any object held by the spectral hand is teleported into your open hand or to an unoccupied space at your feet. Teleporting an object via this method is unreliable and has a chance to fail. Roll a d20 to determine if you are successful. If you have had physical contact with the object before add 5 to your roll. If the object has spent more than 24 hours in your possession, add 10. The DC is 15. On a failure, the object reappears in the space that it occupied before the spectral hand interacted with it, or in the nearest unoccupied space if that space is now occupied.
  Once used, the thieving power of the crystal ball can’t be used again until the next dawn.
