The Iron Throne

You reach into the mind of one creature you can see within range. The target must make a Wisdom saving throw, taking 8d8 psychic damage on a failed save, or half as much damage on a successful one. You conjure terror in the target's mind as its consumed by horrific psychic energy causing them to replay the Game of Thrones season 8 episode 6 series finale The Iron Throne in an endless loop. 

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d8 for each slot level above 6th.
