This crystal ball is about 6 inches in diameter. While touching it, you can cast the scrying spell (save DC 17) with it. While scrying with the crystal ball, you can communicate telepathically with creatures you can see within 30 feet of the spell's sensor and can cast the suggestion spell (save DC 17) through the sensor on those creatures. You don't need to concentrate on this suggestion to maintain it during its duration, but it ends if scrying ends.
