Warlock Punch

You deliver a thunderous, dark-energy-fueled blow from your hand. Make an unarmed melee attack against a creature within your reach. On a hit, the target takes 2d8 force damage and must make a strength saving throw. On a failure, the target is pushed back 10 feet.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
