Deceit

You speak a lie as part of the casting of this spell, enchanting your voice with a stupefying timbre. Each creature you choose within 5 feet of you that can hear and understand you must make a Wisdom saving throw. On a failed save, a creature believes your lie to be true until the spell ends or until you or your companions do anything harmful to it. A creature might believe a convincing lie to be true even after the spell ends.
