Hit Points

• Hit Dice: 1d8 per monk level
• Hit Points at 1st Level: 8 + your Constitution modifier
• Hit Points at Higher Levels: 1d8 (or 5) + your Constitution modifier per monk level after 1st

Proficiencies

• Armor: None
• Weapons: Simple weapons, and one Martial weapon.
• Tools: One type of artisan’s tools or one musical instrument.

• Saving Throws: Strength, Dexterity
• Skills: Choose two from Acrobatics, Athletics, History, Insight, Nature, Medicine, Perception, and Stealth.

Beginning at 1st level, while you are wearing no armor and not wielding a shield, your AC equals 10 + your Dexterity modifier + your Wisdom modifier.

At 1st level, your practice of martial arts gives you mastery of combat styles that use unarmed strikes and monk weapons, which are any Simple and Martial Weapons, that lack the heavy and special properties. You gain the following benefits when unarmored and not wielding a shield, and are either unarmed or are wielding a monk weapon:

• When unarmored, you can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes and monk weapons.

• Once per turn, when you hit a creature with an unarmed strike, you can move it 5 feet to an unoccupied space. You cannot push opponents two sizes larger than you, but you can use the rebound to move 5 feet away without provoking attacks of opportunity.

• You can roll a d4 in place of the normal damage of your unarmed strike or monk weapon. This die changes as you gain monk levels, as shown in the Martial Arts column of the Monk table. d6 (2-7th level) / d8 (8-13th level) / d10 (14-19 level) / d12 (20th level). I wanted to keep d4 only for the 1st level of the monk. As if the introduction of ki would allow the monk to empower himself.
  

• When you use the Attack action with an unarmed strike, or a monk weapon on your turn, or you attack with a monk feature that use ki points, you can make one unarmed strike as a bonus action. For example, if you take the Attack action and attack with a quarterstaff, or you cast a spell or a feature that use Ki points, you can also make an unarmed strike as a bonus action, assuming you haven't already taken a bonus action this turn.

In this feature I incorporated "Dedicated Weapon", "Ki-Fueled Attack" and incorporated part of the "Crusher" feat because I am convinced that it is an adequate solution to the monk's mobility problem. My question is whether they are incorporated well enough to be acceptable.

Starting at 2nd level, your speed increases by 10 feet while you are not wearing armor or wielding a shield. This bonus increases when you reach certain monk levels, as shown in the Monk table. Additionally, you can take the Dash, Disengage, or Dodge actionas as a bonus action on your turn. When you use one of this actions your jump distance is doubled.

At 4th level, when falling, you can use your reaction to reduce your fall damage by an amount equal to five times your monk level.

At 9th level, you gain the ability to move along vertical surfaces and across liquids on your turn without falling during the move.

In this feature I incorporated "Patient Defense" and "Step of the Wind," making them free of their ki-point cost. Some of you will think that Dodge action is too OP to be without cost, but I am of the opinion that Hide could be even more beneficial. An opponent you don't see cannot hit it, while an opponent who is preparing to dodge can always be hit if the roll to hit is high enough. But maybe I am forgetting something if you have another opinion I will be glad to hear it. In This feature I also added "Slow Fall" being very much in line with the acrobatic movements of a monk.

Monks make careful study of a magical energy that most monastic traditions call ki. This energy is an element of the magic that suffuses the multiverse-specifically, the element that flows through living bodies.

Ki Cultivation

Your monk level determines the number of points you have, as shown in the Ki Points column of the Monk table. You can spend these points to fuel various Ki Techniques. When you spend a ki point, it is unavailable until you finish a short or long rest, at the end of which you draw all of your expended ki back into yourself. You must spend at least 30 minutes of the rest meditating to regain your ki points.

Ki Techniques

Starting at 2nd level, when you obtain this feature, you learn four Ki Techniques, which you can choose from the Monk Ki Techniques list. As you increase in level, you learn more techniques, as indicated in the Techniques Known column of the monk table. Additionally, when you gain a Monk level, you can exchange any known Ki Technique for another for which you meet the level prerequisites. You cannot repeat the same technique on the same creature in the same turn, and each technique consumes 1 ki point. Some of the Ki Techniques require your target to make a saving throw to resist the feature's effects. The saving throw DC is calculated as follows:

2nd level 4 Ki Techniques / 5th level 6 KT / 8th level 8 KT /  12th Level 10 KT /  16th level 12 KT / 20th level 14 KT

Ki techniques originated as a variation on the fighting styles and spells of the warrior classes. In this feature I wanted to solve the problem of repetitive "Stunning Strikes" by giving the player the concept of combining different martial arts techniques. One example is to combine "Sweep" with "Ki Blocking" or "Pushing Strike" with "Two in One Strike." The combinations can be up to a number equal to the number of the monk's attacks. These techniques are designed to replace the monk's dependence on stunning strikes and thus have an orderly system of techniques that allows it to be customized to the player's liking.

3rd level:

• Blocking. When a creature hits you with an attack, as a reaction you can add your proficiency bonus to your AC for that attack, potentially causing the attack to miss you.

• Grappler. When you try to grapple, you can choose to use Acrobatics instead of Athletics check. Roll one martial arts die and add the number rolled to your Grapple check.

• Life Force. As a bonus action you can roll a Martial Arts die and regain a number of hit points equal to the number rolled plus your proficiency bonus.

• Pushing Strike. When you hit a creature with an unarmed strike, you can attempt to push it back. It must succeed on a Strength saving throw or it can be pushed up to 15 feet away from you.

Additionally, you can make a ranged attack with 20/60 of range using the object you just caught. The missile counts as a monk weapon for this attack. (Deflect Missiles)

• Disarming Strike. When you hit a creature with an unarmed strike, you can attempt to disarm the target, forcing it to drop one item that it's holding. It must succeed on a Strength saving throw or drop the chosen object. The object lands at its feet.

• Strike Back. When you take damage from a creature in melee, you can use your reaction to make an unarmed attack against it.

• Stunning Strike. When you hit another creature with an unarmed strike, you can interfere with the flow of ki in an opponent's body. It must succeed on a Constitution saving throw or be stunned until the end of your next turn.

Choose another creature within 5 feet of the original target or within your reach. Use the same attack roll to hit the second creature; if it hits, it takes damage equal to a Martial Arts die roll + Wisdom modifier.

Also, on your next turn, it must choose whether to get a move, an action, or a bonus action; it gets only one of the three.

• Wall of Ki. As a bonus action, you can summon the Wall of Force spell without providing material components. This summoning is only active for this turn, but you can maintain it by consuming 1 ki point each turn. (ref. Wall of Force spell)

When you reach 3rd level, you commit yourself to a monastic tradition. Your tradition grants you features at 3rd level and again at 6th, 11th, and 17th level.

Each subclass includes other ki techniques specific to them to be added to the list of ki techniques. This allows the monk to expand the ki techniques and create its own original system of techniques equal to the spells of the magical classes. Monk subclasses are designed to be able to save ki points. If interested you can see each subclass in this link:  https://homebrewery.naturalcrit.com/share/rtFbrp8l4OZL

When you reach 4th level, and again at 8th, 10th, 12th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Starting at 6th level, your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

At 7th level, your instinctive agility lets you dodge out of the way of certain area effects, such as a blue dragon's lightning breath or a fireball spell. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

At 10th level, mastery of the ki flowing through you makes you proficient in Constitution saving throws and immune to diseases and poisons. Additionally, your intense training allows you to empower your Unarmed attacks. Whenever you hit a creature with a Ki Technique, the creature takes one extra Martial Arts die of damage.

Body Cultivation is a damage enhancement through consumption of ki points. This feature makes ki techniques finally comparable to Battle master maneuvers. It could also be compared to Divine Smite of the paladin. This feature also represents the completeness of physically based saving throws and the beginning in the more spiritual pursuit of the monk.

Beginning at 13th level, your long years of meditation and your mastery of ki give you proficiency in all saving throws.

At the 14th level, the harmony achieved between body and mind allows your Ki Techniques to be performed more naturally and in balance. Choose two Ki Techniques between the 3rd and 5th levels that you already know. Once per round, you can perform one of these techniques without spending ki points.

At 18th level, you can choose two Ki Techniques between 8th and 12th levels that you already know. Once per round, you can perform two Ki Techniques you chose in this feature without spending ki points.

By spending 8 hours in meditation, it is possible to exchange all the chosen Ki Techniques in this feature for other techniques.

This solution saves ki points and at the same time maintains the monk's identity, or more precisely its function as a battlefield controller in the group, and this even in the absence of resources. Body Cultivation and Harmony allows the monk to do more damage without owing ki points, thus solving its damage power problem. This feature could be comparable to a cross between the paladin's Improved Divine Smite and the wizard's Spell Mastery.

At 15th level, your ki sustains you so that you suffer none of the frailty of old age, For every 10 years, your body ages only 1 year, and you can't be aged magically. You can still die of old age, however. In addition, you no longer need food or water.

Additionally, you can spend 6 ki points to cast the astral projection spell, without needing material components. When you do so, you can't take any other creatures with you.

At 20th level, you go beyond the human limit. Your body is so used to certain movements that have become one with your being. You can take an additional reaction between each of your turns. Moreover, you can use both inner ki and the ki of heaven and earth, every time you roll for initiative, you will always have at least 4 ki points.

So many are convinced that the 20th-level feature of the monk very disappointing. The additional reaction combines extremely well with ki techniques that use reaction. Giving the monk an almost additional attack. I also modified the basic feature to make it active even if the monk still has 1-3 ki points.
