While touching it, you can cast the [Scrying](https://www.dndbeyond.com/spells/2619007-scrying) spell (save DC 17) with it. --- The following _crystal ball_ variants are legendary items and have additional properties. **[Crystal Ball of Mind Reading](https://www.dndbeyond.com/magic-items/4862-crystal-ball-of-mind-reading).** You can use an action to cast the [Detect Thoughts](https://www.dndbeyond.com/spells/2619099-detect-thoughts) spell (save DC 17) while you are scrying with the _crystal ball_, 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](https://www.dndbeyond.com/spells/2619007-scrying) ends.
