Way of Heaven Sun Fist

This subclass is inspired by martial arts anime in which the practitioner powers themselves up at a cost to be paid later when they return to normal. Examples of these martial arts styles and power are:

• Goku's Kaio-ken from Dragonball Z
• Ichigo’s Bankai from Bleach
• One-for-All from My Hero Academia

The intent is to allow class features to "power up" the character for a short time and then suffer consequences after the moment has passed. The power ups grant enormous raw power, damage, speed, and heightened perception or senses. The consequences incur exhaustion or self-inflicted damage.

A Monk following the Way of Heaven Sun Fist trains their body to endure incalculable strain upon it and equally trains their spirits to inflict that strain on the body in return for unparalleled power, speed, and awareness. Few are ever found who contain the raw potential to follow such a path, fewer still survive the training for it. They must have unusual willpower and the drive to achieve in themselves the power to fulfill a greater purpose. The journey is long, the training brutal, and the masters pitiless, but those that succeed find themselves able to confront and defeat the greatest terrors that threaten their world.

Manifest Ki

3rd-Level Way of Heaven Sun Fist Feature

You can channel ki into your physical being, manifesting preternatural abilities for a time. Dark red veins bulge visibly beneath your skin, and you are surrounded by a bright aura in a hue of your choice (i.e., Gold, Blue, White, Red, etc.). As a Bonus Action you may spend 2 Ki points to gain these benefits for 1 minute. You can maintain your Ki Manifestation by spending an additional 2 Ki points as a Bonus Action before the duration ends, extending its duration another 1 minute. Once the manifestation ends, either because the duration expires without renewal or you are knocked unconscious, you automatically suffer a level exhaustion for every 2 points of Ki spent activating or maintaining the Ki Manifestation.

Upon activation you automatically gain the Revealing Aspect ability for the duration.

Revealing Aspect. Your glowing aura sheds bright light in a 20-foot radius and dim light for an additional 20 feet.

You learn two abilities of your choice, from among those described below, and each time you gain a level in this class, you can replace one ability you know with a different one from this feature. When you reach certain levels in this class, you learn additional abilities, as shown in the Abilities Known table.

The following abilities are available to you when you learn an ability. If an ability has a level requirement, you must be at least that level in the Monk class to learn the ability.

When you use your Flurry of Blows, on a hit you can choose to spend additional Ki Points to add multiple martial arts dice to the damage roll. For every ki point spent you may add 2 rolls of your martial arts die to the damage. However, you suffer half the damage dealt until you have mastered the power level of this attack (Monk Level 11).

Spirit Wave

11th-Level Way of Heaven Sun Fist Feature

The power of your Ki may now be projected as a wave of force, wounding and throwing your enemies prone. Once per turn, when using Ki Points with unarmed strikes, you can replace one of those unarmed strikes with a wave of Ki force in a 15' cone. Any target in the area of affect must make a DEX saving throw or be pushed 10 feet, be knocked prone, and suffer force damage equal to 2 rolls of your martial arts die. If they successfully save, they suffer 1/2 damage and are neither moved nor knocked prone.
