Zone of truth V S

You create a magical zone in a 15-foot-radius
sphere centered on a point within 60ft. Until 10
minutes a creatures in the zone must make a
Charisma saving throw. On a failed save, a creature
can’t speak a deliberate lie while in the radius. You
know whether each creature succeeds or fails on its
saving throw. An affected creature is aware of the
spell and can thus avoid answering questions to
which it would normally respond with a lie.
