Crystal Ball of Mind Reading 5e

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 cast the Detect Thoughts spell (save DC 17) targeting creatures you can see within 30 feet of the spell's sensor. You don't need to concentrate on this Detect Thoughts to maintain it during its duration, but it ends if Scrying ends.
