A bright white streak flashes from your pointing finger to a creature you choose within range and then blossoms with an explosion of magical force. Each creature, excluding the target, within 20 feet of the creature must make a Dexterity saving throw. A creature takes 6d6 force damage on a failed save and is pushed 10 feet away from the target. If the creature succeeds, they take half as much damage and is not pushed.
When you cast this spell using a spell slot of 4th level or higher, increase the damage by 1d6 for each level above the 3rd.
