Bumping Blade

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and if it is a medium creature or smaller, it is pushed 10 feet away from you. If the target collides with something or someone, it takes bludgeoning damage equal to your spellcasting ability modifier

At higher levels. This spell's damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 bludgeoning damage to the target, and the damage the target takes for colliding increases to 1d8 + your spellcasting ability modifier. Both damage rolls increase by 1d8 at 11th and 17th level.
