Way of the Perfected Body

Those who pursue this monastic tradition take it upon themselves to perfect their body above all else. To fully master their ki is to fully master their body, and so these monks develop ways to fully utilize each part of their body.

Battle Physique

Also at 3rd level, your body is much stronger than those of similar physique to you. Your martial art die is increased by one size (1d6), increasing by one size each time it would normally increase as you progress in this class.

You also gain an additional way in using your Deflect Missile feature: you can use your reaction to deflect a melee weapon attack that hits you. If you reduce its damage to 0, you can immediately deal an amount of bludgeoning damage equal to two rolls of your Martial Arts die towards your attacker.

You can perform Deflect Missiles in such a manner a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. While you have no uses available, you can spend 1 ki point to use this feature again.

Incredible Fitness

Upon taking this tradition at 3rd level, you know how to complement your strength and agility together. You gain proficiency in the Athletic and Acrobatic skills.

Additionally, choose Constitution or Strength. You get a bonus to Dexterity checks equal to your chosen ability score's modifier, as well as a bonus to checks using your chosen ability score equal to your Dexterity modifier.

The first creature you hit on each of your turns takes extra damage equal to your chosen ability score's modifier.

Resilient Body

Starting at 6th level, you add your chosen ability score modifier to your Ki save DC, and you have advantage against gaining levels of exhaustion.

Whenever you would make a Strength, Dexterity, or Constitution saving throw, you can choose to do so with advantage.

You can gain advantage in this manner a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. While you have no uses available, you can spend 2 ki point to use this feature again.

Muscles of Steel

At 11th level, your fitness empowers your combat to higher levels. Whenever you start your turn with 0 ki, roll a d6. On a 5 or 6, you regain an amount of ki equal to your chosen ability score modifier (minimum of +1).

Whenever you would reduce a melee weapon attack's damage to 0 through your Empowered Body feature, you can spend 1 ki point to attack your attacker with the weapon they used against you, rather than using your martial die. You make this attack with proficiency, regardless of your weapon proficiencies, and the weapon counts as a monk weapon for the attack.

Finally, whenever you could use your Deflect Missiles feature but have no available reactions, you can spend 3 ki to regain a reaction.

Peak Physique

At 17th level, your fitness has achieved its peak. - Your Martial die is now 2d6. - Whenever you make a Strength, Dexterity, or Constitution ability check or saving throw and the total roll is lower than your respective ability score, you can use your score as the roll instead. - In combat, you get a special reaction that you can take once on every creature's turn, except your turn. You can use this special reaction only to perform Deflect Missiles, and you can't use it on the same turn that you take your normal reaction.

While you have no uses available, you can spend 3 ki point to use this feature again.
