This iridescent crystal ball is about 6 inches in diameter. Multicolored vapor floats within, occasionally forming into a gaseous, lidless eye. It can be used as an Arcane Focus.

While touching it, you can cast the scrying spell (save DC 17) with it. Once used, this power cannot be used again until the next dawn.

While scrying with the crystal ball, you can communicate telepathically with creatures you can see within 30 feet of the spell's sensor. You can also use an action to cast the phantasmal force spell (save DC 17) through the sensor on one of those creatures. You don't need to concentrate on this phantasmal force to maintain it during its duration, but it ends if scrying ends. 

While touching The Shepherd's Eye, you can also cast the Commune spell with it. Instead of a deity or divine proxy, the source of this spell, and the answers you gain, comes from the vast inherited knowledge of all Aboleths and their servitors, reaching into millennia of tortured memory and accrued information. Once used, this power cannot be used again until next dawn.
