You attempt to implant a new self in a humanoid that you can see within range. It must succeed on a Wisdom saving throw or be implanted for the duration.
When you cast this spell, you choose a sentence to use as a trigger (such as "Until we meet again, wrapped in the Lord's embrace"). As long as the target is implanted and the two of you are on the same plane of existence, you can speak the trigger phrase as an action, forcing the target to make a Charisma saving throw, activating the implanted self to overwrite the real self for 1 hour on a failed save. The implanted self can be as similar or different to the creature's real self as you wish, including false memories, motivations, loyalties, and personality traits. When the hour ends, the implanted self becomes dormant and cannot be activated again for 3 days, causing the real self to reemerge, having no memory of the past 1 hour.
Unless cast using a spell slot of a level equal to or greater than this spell, when successfully dispelled by dispel magic, the effect is merely suppressed for 7 days, not ended. Otherwise, the spell ends. The spell also ends if you cast it again, regardless of the target.
