Convincing Lie

You attempt to magically make a lie more convincing. You target a creature within 30 feet of you that can hear you, that creature must make an intelligence saving throw. On a successful save, the creature knows that you tried to magically influence it. If it fails its saving throw, then it will believe the next lie that you tell it unless this spell is dispelled or it sees something that unmistakably contradicts the lie (for example if you told them someone was dead and that person is alive and well, this spell's effect will fade). If the spell is not dispelled or it doesn't see something that directly contradicts the lie, the creature continues to believe that lie. 

At Higher Levels. When you cast this using a 6th level slot or higher, the creature will instead believe every lie you tell it for the next minute.
