You approach a creature within range and reach out to touch it, making an unarmed attack roll. On a hit, the target creature takes 5d6 force damage and is knocked 15 feet in the opposite direction and must make a Dexterity saving throw equal to your Spell save DC or be knocked prone. If the creature hits a wall or another creature before the 15 feet of movement are expended, all creatures involved are knocked prone where they collide and take an additional 2d4 bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d6 for each slot level above 3rd.
