You create a magical zone that fosters deceit in a 15-footradius sphere centered on a point of your choice within range. Until the spell ends, a creature that enters the spell's area for first time or starts its turn there must make a Charisma saving throw. On a failed save, a creature can't discern lies from truth while in the radius, as with making a Wisdom (Insight) check or another way. A creature that fails the save and that can automatically discern lies, such as one with the Divine Awareness trait, can't automatically discern them, but can still make Wisdom (Insight) checks to determine truth as normal. You know whether each creature succeeds or fails on its saving throw. However, creatures affected by this spell don't know if they are or not. Any Wisdom (Insight) checks they make to determine truth are inconclusive. If this spell affects another player character, the DM makes their saving throws in secret.
