Choose one creature that you can see within range. You and that creature both fall unconscious and you create a terrible vision in the mind of the affected creature. Creatures that can't be charmed are immune to this spell.

When you cast this spell you may use up to 3 words to describe the vision the affected creature is experiencing. If the creature is afraid of the vision, it has disadvantage on saving throws to escape it. Additionally, once per turn, on your turn, you may choose to Intensify or Enhance the vision: if you choose to Intensify, increase the damage the vision does by 2d8; if you choose to Enhance, increase the DC of the saving throw by 1.

While unconscious, the target takes 5d8 Psychic Damage at the start of its turn. Then it may make a Wisdom saving throw at the end of its turn, or if it is hit by an attack which does not deal Psychic damage. On a success the spell ends.
