Anima Exstirpo

You attempt to extract the soul of a living creature within range. The target must make a Constitution saving throw. On a failed save, the target takes 6d8 necrotic damage and is incapacitated for the duration. On a successful save, the target takes half as much damage and is not incapacitated.

At the end of each of its turns, the target can make another Constitution saving throw. On a success, the spell ends.

The spell ends early if the target dies, the caster dies, or the caster dismisses the spell as an action.
