Earth's Fury

 You rake stones over your weapon of choice and embed them into it. The stones grow in size and become jagged coating your armament. This gives your weapon (no matter the size) the Heavy property, and allows you to deal an extra +2d8 Bludgeoning damage with every successful hit.

Any enemies who are currently flying or climbing must make a Strength Saving Throw against your Spell Save DC whenever they are hit with your weapon, or be flung back to the ground.
