Death's Grip

You utter a single deathly phrase calling the very hand of death to descend upon your enemies. Choose 5 creatures you can see within range. Each creature must make a Wisdom saving throw or be wracked by the sorrow and despair brought by death. On a failed save, a creature’s current and maximum hit points are reduced by 10d10. A creature cannot restore its maximum hit points until it finishes a long rest or has remove curse cast on it.
