You attempt to reshape another creature's memories. 1 creature that you can see must make a Wis saving throw — if you are fighting, it has advantage. On a fail, the target becomes charmed and is incapacitated, though it can still hear you. If it takes any dmg or is targeted by another spell, this spell ends.

You can affect the target's memory of an event it experienced in the last 24 hrs and that lasted no more than 10 min. You can change its memory of the event, or create a memory of some other event. The target must understand your language. Its mind fills in any gaps in the details of your description. A remove curse or greater restoration spell cast on the target restores the creature's memory. For further details, see the PHB.
