Whisper of Deceit

You whisper conniving thoughts into the mind a creature within range. The creature must make a wisdom saving throw, if it succeeds then it knows its mind was attempted to be tampered with but it doesn't know who did it and the spell fails, if it fails then the nearest creature to it that it perceives as an ally is instead perceived by it as an enemy for the duration of the spell. As an action during the duration of the spell, you can choose to keep the creature under the spell for longer without expending further spell slots, thus whispering reassuring words into its mind to convince it that its thoughts are right, and requiring that it make another wisdom save when you do this, if it succeeds then the spell ends and the creature knows its mind was tampered with but doesn't know by who, if it fails then the spell's duration is reset on that creature. You can use a bonus action to end the spell prematurely.
