Still is the fist of those who follow the Truths, since the secrets of this tradition transcend the worldview proper to mortals. Whatever adversity these monks face, their minds remain firm, without yielding to the human emotions that are so trifling when compared to the Four Truths.   Among the followers of the Old Tradition there are martial masters whose discipline leverages the awareness given by the Four Truths.
Each of the Four Truths is linked to a specific secret technique, handed down in temples to those who can see through the mere words recited in the Truth and reach its purest intrinsic meaning. This technique makes it possible to equate oneself with the cosmos, and from this awareness draw further energy.
Once training is complete, the novices leave the temple to begin a path of inner growth, becoming warriors and protectors. They are ready to face the dangers of the endless night and their spirit is guided by the deep awareness of themselves and the world that they have grown to understand after years of study and martial practice.  

First Technique, Sidereal Void Touch

At 3rd level, you being to put your studies into practice and learn to manipulate the energy of the Sempiternal who echoes through everything in the form of Ki and, with this energy, send your enemies back into the sidereal void.
When you hit a target with an attack granted by Flurry of Blows, the target must make a successful Wisdom Saving Throw or, instead of taking the appropriate damage, be exiled to a demiplane out of time and space where it is Incapacitated. At the end of its next turn, the target reappears in the precise spot where it disappeared.
Using this technique successfully results in one level of Exhaustion unless you make a successful Constitution Saving Throw with DC 10 + the target’s Challenge Rating.  

Second Technique, Awakening of Existence

At 6th level, if you start your turn at 0 Hit Points, you can spend any amount of Ki points you choose to immediately recover 5 Hit Points for each Ki point spent.  

Third Technique, Tearing Up the Dark Veil

At 11th level, when you hit an Aberration, Fiend or Undead with an unarmed strike, you deal 1d4 additional radiant damage.  

Fourth Technique, Event Horizon

At 17th level, whenever you fail an Attack Roll, a Saving Throw or a Skill check, you can spend 10 Ki points to automatically succeed instead.
 

Way of the Shadow

Monks of the Way of Shadow follow a tradition that values stealth and subterfuge. These monks might be called ninjas or shadowdancers, and they serve as spies and assassins. Sometimes the members of a ninja monastery are family members, forming a clan sworn to secrecy about their arts and missions. Other monasteries are more like thieves’ guilds, hiring out their services to nobles, rich merchants, or anyone else who can pay their fees. Regardless of their methods, the heads of these monasteries expect the unquestioning obedience of their students.  

Shadow Arts

Starting when you choose this tradition at 3rd level, you can use your ki to duplicate the effects of certain spells. As an action, you can spend 2 ki points to cast darkness, darkvision, pass without trace, or silence, without providing material components. Additionally, you gain the minor illusion cantrip if you don’t already know it.  

Shadow Step

At 6th level, you gain the ability to step from one shadow into another. When you are in dim light or darkness, as a bonus action you can teleport up to 60 feet to an unoccupied space you can see that is also in dim light or darkness. You then have advantage on the first melee attack you make before the end of the turn.  

Cloak of Shadows

By 11th level, you have learned to become one with the shadows. When you are in an area of dim light or darkness, you can use your action to become invisible. You remain invisible until you make an attack, cast a spell, or are in an area of bright light.  

Opportunist

At 17th level, you can exploit a creature’s momentary distraction when it is hit by an attack. Whenever a creature within 5 feet of you is hit by an attack made by a creature other than you, you can use your reaction to make a melee attack against that creature.
 

Way of the Elements

You follow a monastic tradition that teaches you to harness the elements. When you focus your ki, you can align yourself with the forces of creation and bend the four elements to your will, using them as an extension of your body. Some members of this tradition dedicate themselves to a single element, but others weave the elements together.
Many monks of this tradition tattoo their bodies with representations of their ki powers, commonly imagined as coiling dragons, but also as phoenixes, fish, plants, mountains, and cresting waves.  

Disciple of the Elements

When you choose this tradition at 3rd level, you learn magical disciplines that harness the power of the four elements. A discipline requires you to spend ki points each time you use it.
You know the Elemental Attunement discipline and one other elemental discipline of your choice, which are detailed in the “Elemental Disciplines” section below. You learn one additional elemental discipline of your choice at 6th, 11th, and 17th level.
Whenever you learn a new elemental discipline, you can also replace one elemental discipline that you already know with a different discipline.  

Casting Elemental Spells

Some elemental disciplines allow you to cast spells. See the Spellcasting section for the general rules of spellcasting. To cast one of these spells, you use its casting time and other rules, but you don’t need to provide material components for it.
Once you reach 5th level in this class, you can spend additional ki points to increase the level of an elemental discipline spell that you cast, provided that the spell has an enhanced effect at a higher level, as burning hands does. The spell’s level increases by 1 for each additional ki point you spend. For example, if you are a 5th-level monk and use Sweeping Cinder Strike to cast burning hands, you can spend 3 ki points to cast it as a 2nd-level spell (the discipline’s base cost of 2 ki points plus 1).
The maximum number of ki points you can spend to cast a spell in this way (including its base ki point cost and any additional ki points you spend to increase its level) is determined by your monk level, as shown in the Spells and Ki Points table.

On a successful save, the creature takes half as much damage, and you don’t pull it or knock it prone.

 

Way of the Open Hand

Monks of the Way of the Open Hand are the ultimate masters of martial arts combat, whether armed or unarmed. They learn techniques to push and trip their opponents, manipulate ki to heal damage to their bodies, and practice advanced meditation that can protect them from harm.  

Open Hand Technique

Starting when you choose this tradition at 3rd level, you can manipulate your enemy’s ki when you harness your own. Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:

• It must succeed on a Dexterity saving throw or be knocked prone.
• It must make a Strength saving throw. If it fails, you can push it up to 15 feet away from you.
• It can’t take reactions until the end of your next turn.

 

Tranquility

Beginning at 11th level, you can enter a special meditation that surrounds you with an aura of peace. At the end of a long rest, you gain the effect of a sanctuary spell that lasts until the start of your next long rest (the spell can end early as normal). The saving throw DC for the spell equals 8 + your Wisdom modifier + your proficiency bonus.  

Quivering Palm

At 17th level, you gain the ability to set up lethal vibrations in someone’s body. When you hit a creature with an unarmed strike, you can spend 3 ki points to start these imperceptible vibrations, which last for a number of days equal to your monk level. The vibrations are harmless unless you use your action to end them. To do so, you and the target must be on the same plane of existence. When you use this action, the creature must make a Constitution saving throw. If it fails, it is reduced to 0 hit points. If it succeeds, it takes 10d10 necrotic damage.
You can have only one creature under the effect of this feature at a time. You can choose to end the vibrations harmlessly without using an action.
 

Way of the Kensei

Monks of the Way of Kensei train relentlessly with their weapons, to the point that the weapon becomes like an extension of the body. Founded on a mastery of sword fighting, the tradition has expanded to include many different weapons.
A kensei sees a weapon much in the same way a calligrapher or a painter regards a pen or brush. Whatever the weapon, the kensei views it as a tool used to express the beauty and precision of the martial arts. That such mastery makes a kensei a peerless warrior is but a side effect of intense devotion, practice, and study.  

Path of the Kensei

When you choose this tradition at 3rd level, your special martial arts training leads you to master the use of certain weapons. This path also includes instruction in the deft strokes of calligraphy or painting. You gain the following benefits:

• Kensei Weapons. Choose two types of weapons to be your kensei weapons: one melee weapon and one ranged weapon. Each of these weapons can be any simple or martial weapon that lacks the heavy and special properties. The longbow is also a valid choice. You gain proficiency with these weapons if you don't already have it. Weapons of the chosen types are monk weapons for you. Many of this tradition's features work only with your kensei weapons. When you reach 6th, 11th, and 17th level in this class, you can choose another type of weapon – either melee or ranged – to be a kensei weapon for you, following the criteria above.
• Agile Parry. If you make an unarmed strike as part of the Attack action on your turn and are holding a kensei weapon, you can use it to defend yourself if it is a melee weapon. You gain a +2 bonus to AC until the start of your next turn, while the weapon is in your hand and you aren’t incapacitated.
• Kensei's Shot. You can use a bonus action on your turn to make your ranged attacks with a kensei weapon more deadly. When you do so, any target you hit with a ranged attack using a kensei weapon takes an extra 1d4 damage of the weapon’s type. You retain this benefit until the end of the current turn.
• Way of the Brush. You gain proficiency with your choice of calligrapher's supplies or painter's supplies.

 

One with the Blade

At 6th level, you extend your ki into your kensei weapons, granting you the following benefits.

• Magic Kensei Weapons. Your attacks with your kensei weapons count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
• Deft Strike. When you hit a target with a kensei weapon, you can spend 1 ki point to cause the weapon to deal extra damage to the target equal to your Martial Arts die. You can use this feature only once on each of your turns.

 

Sharpern the Blade

At 11th level, you gain the ability to augment your weapons further with your ki. As a bonus action, you can expend up to 3 ki points to grant one kensei weapon you touch a bonus to attack and damage rolls when you attack with it. The bonus equals the number of ki points you spent. This bonus lasts for 1 minute or until you use this feature again. This feature has no effect on a magic weapon that already has a bonus to attack and damage rolls.  

Unerred Accuracy

At 17th level, your mastery of weapons grants you extraordinary accuracy. If you miss with an attack roll using a monk weapon on your turn, you can reroll it. You can use this feature only once on each of your turns.
 

Way of Mercy

Monks of the Way of Mercy learn to manipulate the life force of others to bring aid to those in need. They are wandering physicians to the poor and hurt. However, to those beyond their help, they bring a swift end as an act of mercy.
Those who follow the Way of Mercy might be members of a religious order, administering to the needy and making grim choices rooted in reality rather than idealism. Some might be gentle-voiced healers, beloved by their communities, while others might be masked bringers of macabre mercies.
The walkers of this way usually don robes with deep cowls, and they often conceal their faces with masks, presenting themselves as the faceless bringers of life and death.  

Implements of Mercy

When you choose this tradition at 3rd level, you gain proficiency in the Insight and Medicine skills, and you gain proficiency with the herbalism kit.
You also gain a special mask, which you often wear when using the features of this subclass. You determine its appearance, or generate it randomly by rolling on the following: 1 - Raven, 2 - Black and White, 3 - Crying visage, 4 - Laughing visage, 5 - Skull, 6 - Butterfly  

Hands of Healing

At 3rd level, your mystical touch can mend wounds. As an action, you can spend 1 ki point to touch a creature and restore a number of hit points equal to a roll of your Martial Arts die + your Wisdom modifier.
When you use your Flurry of Blows, you can replace one of the unarmed strikes with a use of this feature without spending a ki point for the healing.  

Hands of Harm

At 3rd level, you use your ki to inflict wounds. When you hit a creature with an unarmed strike, you can spend 1 ki point to deal extra necrotic damage equal to one roll of your Martial Arts die + your Wisdom modifier. You can use this feature only once per turn.  

Physician's Touch

Starting at 6th level, you can administer even greater cures with a touch, and if you feel it's necessary, you can use your knowledge to cause harm.
When you use Hands of Healing on a creature, you can also end one disease or one of the following conditions affecting the creature: blinded, deafened, paralyzed, poisoned, or stunned.
When you use Hands of Harm on a creature, you can subject that creature to the poisoned condition until the end of your next turn.  

Flurry of Healing and Harming

Starting at 11th level, you can now mete out a flurry of comfort and hurt. When you use Flurry of Blows, you can now replace each of the unarmed strikes with a use of your Hands of Healing, without spending ki points for the healing.
In addition, when you make an unarmed strike with Flurry of Blows, you can use Hand of Harm with that strike without spending the ki point for Hands of Harm. You can still use Hands of Harm only once per turn.  

Hand of Ultimate Mercy

By 17th level, Your mastery of life energy opens the door to the ultimate mercy. As an action, you can touch the corpse of a creature that died within the past 24 hours and expend 5 ki points. The creature then returns to life, regaining a number of hit points equal to 4d10 + your Wisdom modifier. If the creature died while subject to any of the following conditions, it revives with them removed: blinded, deafened, paralyzed, poisoned, and stunned.
Once you use this feature, you can't use it again until you finish a long rest.
