Monk Monastic Tradition: Way of the Boulder

Some monastic adherents choose brawn and girth over lithe speed. These monks use their incredible size and formidable stature to toss their foes like play things and crush them beneath their weight. They spend much of their meditation time eating and strength training, constantly trying to increase their size and strength. Despite their rotund features, they train to be surprisingly agile and quick, which often leads viewers of their unique styles of martial combat to associate their appearance with boulders rolling from the mountains.

Girth of the Mountain

Starting at 3rd level, you use your constitution instead of your dexterity to calculate your unarmored defense and your hit point maximum increases by 1, increasing by 1 again whenever you gain a level in this class.

Additionally, your weight increases by 2d4x10 lbs.

Swift as a Coursing River

At 3rd level, when you use your Patient Defense feature, you may use your reaction to become the target of an attack that targets a friendly creature within 5 feet of you. If the attack hits, you may spend 1 Ki and roll a martial arts die to reduce the damage by the result.

Force of a Great Typhoon

Beginning at 6th level, if you successfully shove a creature you may spend 1 Ki and roll a martial arts die to provide one of the following effects.

If you choose for the creature to become prone, it takes damage equal to the result plus your strength modifier.

If you choose to push the creature, it is moved a distance of five times the result in feet.

In addition, you are treated as one size larger for the purposes of grappling and shoving.

Strength of a Raging Fire

Mysterious as the Dark Side of the Moon
