The Way of the Kirin isn't a path that most monks take. As it requires a balance of clarity and emotion, aura is powerful, but it also is a curse. Most that take this path, learn it from either a single mentor, or on their own. There are no known monastic orders of Kirin, but it is a journey like the other ways that monks follow. Mastery of the body and spirit is shared by all monks, but this path to enlightenment is fraught with peril. Few survive, as aura burns the user, should they be unable to control themselves.

Aura Use

Aura techniques can only be used once per round. Abilities such as Action Surge do not permit you to use an additional aura technique that turn. 

Your Aura points are determined as follows.
Class Level + Constitution Modifier

Recovery of Aura
During battle, you may use your entire action to meditate and restore a number of aura points equal to your Wisdom modifier (Maximum of your Con Modifier).
Out of combat, you must use a Long Rest to recover your Aura.

Overcharge Rules
If you cannot afford the Aura cost of a technique, and you have at least 1 point of aura, you may Overcharge the ability if it has an Overcharge cost. Overcharging lets you use your body as fuel for the power, and take a detrimental effect in exchange for the power's usage. Using Overcharge sets your current Aura pool to 0, and you cannot use Overcharge or other Aura abilities without at least 1 point of aura.

All Monk abilities you gain while adventuring, have their costs changed from Ki points to Aura points.

Body Replenishing

At 6th level or higher, so long as you have at least 1 Aura point in your pool, you do not need to eat, drink or sleep when you take a long rest. You may perform light activity during your long rest, but not combat or heavy exertion.

Overcharge Mastery

At 11th level or higher, whenever you use an Overcharge ability that damages you, you may reduce the damage by your Constitution modifier times your Proficiency Bonus. This ability can be used a number of times equal to your Constitution modifier, and you regain all uses on completion of a short or long rest.

Aura Corruption

Corruption (17th level Class Ability)
8 Aura Points
A single target within 30 feet must make a Constitution saving throw. Failure deals 8d10 Psychic Damage, Success halves the damage. If the
target fails by 5 or more, they must make a second CON saving throw. If they fail the second saving throw, they die as if subjected to a successful Power Word Kill, regardless of the number of hit points the target has remaining. This ability can be used up to the lower of your Constitution or Wisdom modifiers per day, and are recharged on a short rest.
Cannot be Overcharged

Furthermore, when you gain the Perfect Self monk Class Feature, on rolling for initiative, you gain 4 plus your Wisdom or Constitution modifier in Aura points back, if you have no aura points remaining.
