Way of Acupuncture

Monks training in the Way of Acupuncture learn about the pressure points of the body, and train to accurately hit them with their Ki.
With their use of Acupuncture they can manipulate bodies of others and themselves in a certain ways. Those methods can be healing, disabling and even deadly to the target.

Some monastries only delve in the healing and relaxing aspects of Acupuncture, while others dig deeper and learn the darker practices of it. 

Pressure Point Technique

Starting when you choose this tradition at 3rd level, you can manipulate your enemy’s ki when you harness your own. Once per turn, when 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 has disadvantage on attack rolls with weapons until the end of your next turn.
• It is deafened until the end of your next turn.
• It is blinded until the end of your next turn.
• It's movement speed is halved until the end of your next turn.

Paralyzing Strike

At 6th level, you learn how to strike an important pressure point that paralyzes creatures when struck. When you hit another creature with a unarmed attack, you can spend 2 ki points to attempt a paralyzing strike. The target must succeed on a Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of its turn.

Limit Remover

Beginning at 11th level, you can effect your own limiter of muscle output, to use more of your bodies capabilities for 1 minute. There are different levels of output, coming at the cost of levels of exhaustion as an aftereffect, that kick in after 1 minute of usage is over.

As a bonus action or one attack during your action, you can spend upto 6 ki points, 1 ki point per level, to gain the following effects and aftereffects:

• 1st level: Spending 1 Ki Point, your Strength score increases by 6 for 1 minute, after the 1 minute is over, you get 1 level of exhaustion.
• 2nd level: Spending 2 Ki Points, you gain the effect of the previous level, and in additon your Dexterity score increases by 6 for 1 minute. Afterwards you get 2 levels of exhaustion.
• 3rd level: Spending 3 Ki Points, you get all the effects from previous levels, and in addition you can make 1 additional attack as part of your attack action. The backlash is 3 levels of exhaustion and a penalty of -2 to your Strength and Dexterity score.
• 4th level: Spending 4 Ki Points, you get all the effects from previous levels, and in addition, you can make 1 more additional attack as part of your attack action. Getting 4 levels of exhaustion after the effect wears off and a penalty of -4 to your Strength and Dexterity score..
• 5th level: Spending 5 Ki Points, you get all effects from the previous levels, in additon the number of damage die of your attacks increases by 1. The backlash is 5 levels of exhaustion and a penalty of -4 to your Strength and Dexterity score, your speed is 0 for the next 30 days.
• 6th level: Spending 6 Ki Points, you get all effects from the previous levels, in addition the number of damage die of your attacks is increased by 1 once more. The backlash is 6 levels of exhaustion and a penalty of -4 to your Strength and Dexterity score, your speed is 0 for the next 30 days, even if you do get revived, your natural remaining lifespan is halved.

The penalty to Strength and Dexterity scores can be quickly regained. With 7 days of intensive training, one penalty point of each score can be nullified. 
If you already have exhaustion of any level, you can overshoot the aftereffect of exhaustion, for example using 4th level of Limit Remover, when you aleady have 3 levels in exhaustion. In that case you would have the 4th level effect going on while you have 3 levels of exhaustion and after it is over, you immediatly shoot up to level 6 of exhaustion and die, but not suffering the other aftereffects from 6th level Limit Remover.
Getting incapacitated, while using Limit Remover before the backlash, won't end the effect until the minute is over, and you'd suffer the backlash even while incapacitated.

Touch of Death

At 17th level, you gain the ability to find the vital pressure points inside a creature's body such as the key part in the brain and the heart to be especially deadly in one strike.
As an action you can spend 5 ki points to make the next attack target said pressure point of your choice.
There are two ways to use this feature, the first one during combat and the other way only works on unsuspecting targets, as it requires extra care to apply correctly.

Touch of Death in Combat:
As an action you can either target the brain or the heart for your attack, if a creature doesn't have the one that you chose, that this attack has no effect.
Either way, make an unarmed attack roll, but for the damage it instead deals 12d12 necrotic damage, if you target the heart, or 12d12 psychic damage if you target the brain.

Touch of Death out of Combat:
As an action, you touch the target in either the heart or the brain and send your Ki, hitting the pressure point with it. A target that doesn't trust you, might try to stop you, in that case use the "in Combat" variation. The targeted creature does not feel any pain from it, just as if it was touched normally. After 1d10 days the effect comes to be. If the target was touched at the head, it has to make a Wisdom saving throw, if it was touched at the chest, it has to make a Constitution saving throw. If it fails the save, the creature dies. If it succeeds, the creature takes 8d8 necrotic damage, if the target was the heart, or 8d8 psychic damage if it was the head.
