Path of the Boulder

The path of the boulder flows unerringly in one direction, downhill. Few can stand in the path of such steadfast warriors, whose relentless blows can fell even the mightiest of foes. 

Seismic Leap

Starting when you choose this path at 3rd level, you can unbalance your foes when you rage. For the duration of your rage  when you jump after moving at least 10 feet, creatures within 5ft of square you land your jump must make a strength saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier) or be knocked prone.

Stone Stance

Beginning at 6th level, you can’t be knocked prone or be the target of forced movement while raging. If you are prone when you enter your rage, you may immediately spend 5ft of movement to stand. 

Weight of the Mountain

Beginning at 10th level, while you are raging, when you knock a creature prone, they make a strength saving throw (DC 8 + proficiency bonus + Strength modifier) or be grappled by the earth. At the start of each prone creature's turn, they may repeat the saving throw to escape the grapple. 

If the creature succeeds on its saving throw, this feature has no effect on that creature again for 24 hours.

Crushing Blows

Starting at 14th level, when you hit a prone creature within 5 feet of you with an attack, you may add an additional weapon damage die.
