Way of the Boulder

Hidden in monasteries upon high mountain tops or practicing their art in lonesome enclaves deep underground, monks who follow the Way of the the Boulder seek to harness the power of the very ground they walk upon.

It is known that this often reflects on their personalities where they often take on certain traits of the terrain that surrounds them. A practitioner of these arts may become stoic and stubborn while traveling across a mountain range, impulsive and short tempered whilst traversing an arid desert or overly friendly and trusting when visiting lush and fruitful lands.

Wherever they find themselves, monks who choose this path share a strong connection with the land they currently find beneath their feet.

Roots of the Mountain Starting when you choose this path at 3rd level the connection you have to the land you walk upon has given you increased vitality. Your hit point maximum increases by 3 and increases by 1 again whenever you gain a level in this class. In addition, when you are hit by a melee weapon attack, you can spend 1 Ki point as a reaction to reduce the damage by an amount equal your Wisdom modifier + the number rolled on your Martial Arts die. If you reduce the damage of the triggering attack to 0, you may try to shove or grapple the creature that attacked you as a part of the same reaction.

Veins of the Earth The innate connection you share with the ground beneath your feet gives you an intimate understanding of your surroundings and the ability to channel its power. Beginning at 6th level you may spend 1 Ki point as a bonus action to gain Tremorsense within a range of 30 feet for a duration of 10 minutes. In addition, you can spend 2 Ki points as an action to cast Enlarge/Reduce on yourself without providing vocal or material components. If you choose the Reduce option of the spell, you gain a burrowing speed equal to half your normal speed for the duration. You can burrow this way through earth, sand or loose pebbles but not through solid rock. While you are in Stonefoot Stance, you have advantage on any Constitution saving throws you have to make in order to maintain concentration on this effect.

Crushing Weight of the Mountain Starting at 11th level your grip is strong enough to shatter bones. While you are in Stonefoot stance and a creature that is grappled by you tries to escape your hold with an opposed Athletics or Acrobatics check, you may use your reaction to constrict the target, inflicting damage equal to your Martial Arts die + half your Monk level.
