Zone of Truth

You create a magical zone that guards against deception in a 15-foot-radius sphere centered on a point you choose within range. When a creature enters the spell’s area for the first time on a turn or starts its turn there, it must make a Charisma saving throw. On a failure, a creature can’t speak a deliberate lie while within the radius of the spell. 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. Such a creature can be evasive in its answers as long as it remains within the boundaries of the zone of truth.
