You create a magical threshing blade that spins and grows as it flies out from you. Each creature in a 60-foot cone must make a Dexterity saving throw. On a failed save, a creature takes 6d10 slashing damage and is lacerated for 1 minute. On a successful save, a creature takes half the damage and isn’t lacerated. A lacerated creature takes 1d10 slashing damage at the start of each of its turns and can’t regain hit points until the laceration ends.    At the end of each of its turns, a lacerated creature can make a Constitution saving throw. On a success, the laceration ends. Alternatively, a creature can take an action to stanch the laceration with a successful Wisdom (Medicine) check against your spell save DC.
