You wrack one creature that you can see within range with agonizing magical pain. The target must succeed on a Constitution saving throw or else become stunned for the duration. It repeats the saving throw at the end of each of its turns, ending the spell on a success.

When a creature that has blood and less than half of its hit points fails the saving throw, it takes 1d6 psychic damage. This damage can't reduce it below 1 hit point.

Creatures that can't be charmed have advantage on the saving throw. This spell has no effect on constructs and undead.
