Path of the Rock Crusher

You wanted to become strong enough to change the landscape, so you have spend many days crushing rocks with your bare hands. Your body has hardened to crush anyone is your path, and eventually, shape mountains.

Hardened Body

At 3rd level, your body is trained to make your physical abilities stronger than they were before. Your unarmed strikes are counted as melee weapons and can deal bludgeoning damage equal to 1d6 + your Strength modifier on a hit while you are wielding a weapon. If you aren't wielding any weapons when you make the attack roll, the d6 becomes a d8. At the start of each of your turns, you can deal 1d4 bludgeoning damage to one creature grappled by you. Additionally, while raging, you can add your half proficiency bonus to your AC (rounded up) while not wearing armor. You can use a shield and still gain a benefit from this effect.

The damage changes to 1d8 while armed and 1d10 while unarmed at 9th Level and 1d10 and 1d12 respectively at 13th Level.

Jackhammer Attack

At 6th level, you've honed your attack speed to more efficiently destroy rock. Whilst raging, you can use your bonus action to attack with an Unarmed Strike.

Rock Defender

At 10th level, our time crushing rocks has allowed you to be able to keep others out of harm's way. Whenever a willing creature within 5 feet of you would be hit by a melee attack, you can push them 5 feet away into an unoccupied space and divert the attack to you. Additionally, you can use your reaction to throw move a creature out of the way of area effects, such as a red dragon's fiery breath or an Ice Storm spell. When a willing creature within 5 feet of you is subjected to an effect that allows them to make a Dexterity saving throw to take only half damage, you instead take no damage and move out of the area of effect if they succeed on the saving throw, and only half damage and any 1 direction within the area of effect if you fail. You can use either features once per short rest. 

Bane of Mountains

At 14th level, you've mastered the ability to literally make your mark on the world. While you’re raging, once per turn, if you hit a creature with an unarmed strike, you can make them make a Strength saving throw, (DC 19) or be knocked prone. Additionally, you can use one of your attacks to create a 5ft space in surface weaker than metal.
