Arcane Hammer

You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects and then the target is shoved 5ft back if it is large or smaller.

At Higher Levels. At 5th level, the melee attack deals an extra 1d10 force damage to the target on a hit, and the target is shoved if it is huge or smaller. At 11th level, the melee attack deals an extra 2d10 force damage to the target on a hit, and the target is shoved 10ft back if it is huge or smaller. At 17th level, the melee attack deals an extra 3d10 force damage to the target on a hit, and the target is shoved 10ft back if it is gargantuan or smaller.
