Range/Area: 60 ft
Components: Verbal, Somatic
Duration: 1 minute (requires concentration)
Attack/Save: CON save
Damage/Effect: psychic
You wrack one creature that you can see within range with agonizing, magical pain, forcing the target to make a Constitution saving throw. On a failed save, the creature is stunned for 1 minute, repeating the saving throw at the end of each of its turns, ending the effect on a success.
When a creature under half of its maximum hit points that has blood fails the saving throw, it also takes 1d6 psychic damage. This damage can't reduce the creature to below 1 hit point. Creatures that can't be charmed have advantage on the saving throw. The spell has no effect on constructs and undead.
