Some monks study how to become light as a feather, dancing and moving along the wind like a petal from a flower. These are not those kinds of monks. Those who study the way of the stone are confrontational and lead with their fists. The connection to body and stone has merged into one with monks who follow this path. Their strikes are more forceful, their bodies are more resilient, and an earthquake is often left in their path. 

Stone Constitution

After choosing this monastic tradition at 3rd level, your hit point maximum increases by 3, and increases by 1 each level you take in this class. 

Stone Fists

Starting at 3rd level, when you make an unarmed strike, you deal additional damage equal to half your proficiency bonus (rounded up). 

Stone Fury

Beginning at Level 6, when you use your Flurry of Blows ability, you may use expend an additional ki point to force any creature you hit to make a Strength saving throw or be knocked prone. 

Stone Protection

Starting at level 11 you gain resistance to slashing damage. 

Stone Smash

Starting at 11th Level when you take the Attack action, you can expend a ki point to replace the attacks with a slam of your stone-like fists into the ground. All creatures within 15 feet of you must make a Dexterity saving throw or take bludgeoning damage equal to a roll of your martial arts die and be knocked prone. 

Stone Slow

Starting at 17th level, when you hit a creature with an unarmed strike you can force the creature to make a Wisdom saving throw. On a failure, the creatures movement speed is halved, cannot take reactions, and can take an action or bonus action until the end of their next turn. A creature can only be forced to make this saving throw once per turn. 

Additionally you can spend 5 ki points to cast the slow spell.
