Carnage

Blood will rain upon the battlefield, and a single warrior will stand alone before the armies of heaven and hell.
When you cast this spell, you teleport 120 feet and make a melee weapon attack against all creatures within your reach. Roll a single attack for all targets. If you hit a creature, it takes an additional 6d12 force damage. On your subsequent turns, you can use your action to continue your deadly assault. Each time you use this action, it has a different effect:
 * 2nd Use: You teleport up to 60 feet and make a melee weapon attack against all creatures within a 20-foot cone. Each creature you hit is knocked prone and takes an additional 6d12 force damage.
 * 3rd Use: You teleport up to 30 feet and make a single melee weapon attack against a creature within reach. If the creature is above half its maximum hit points, this attack inflicts an additional 6d12 force damage. If you hit, the creature is then paralyzed until the end of your next turn.
 * 4th Use: You teleport up to 60 feet into the air and descend, smashing into the ground at a point of your choosing that you can see within 120 feet of your starting point. You take no falling damage, but each creature within 30 feet of you must make a Constitution saving throw. If they fail, they take 6d12 force damage. You then make a melee weapon attack targeting a creature within reach. If you hit, the target takes an additional 8d12 force damage.
