Disciples who pursue the Way of the Eight Trigrams path embody the philosophy of change. Meditating in walking circles, monks of this Way fluidly adapt their form, to confuse and intimidate foes. To study the Eight Trigrams, is to imbue the virtues of the Eight Aspects: Wind, Thunder, Fire, Water, Mountain, Valley, Earth and Heaven. Each aspect focuses on the ebb and flow of energy; where one Aspect seeks to increase offence, the counter Aspect preserves defence. There cannot be creation without destruction. That is the nature of change, and thus, the disciplined Way of the Eight Trigrams.

Aspect of Thunder: Echoing Fury

Beginning at 3rd level, when you successfully hit a target, you may spend a ki point to cause thunder damage equal to half (rounded down) of the triggering attack to each additional target within 5 feet of the affected creature.

Aspect of Wind: Deflecting Gust

Also at 3rd level, when a creature within 30 feet of you is the target of a ranged weapon attack, as a reaction, you may use your Deflect Missiles feature to summon a gust of wind to deter the attack. The normal calculations to reduce the damage apply. 

Aspect of Fire: The Flame Hungers

From 6th level, you manifest a controlled outburst of destructive energy, weakening your constitution. When you activate Flurry of Blows, you may choose to spend one of your remaining Hit Dice to roll a Martial Arts die and deal additional fire damage equal to the number rolled. During one attack, you may use up to a total amount of Hit Dice equal to your Wisdom modifier. Once all of your Hit Dice have been expended, you cannot use this feature until you finish a long rest. This damage will not calculate into your Aspect of Thunder feature. 

Aspect of Water: The Tide Nourishes

Beginning from 6th level, your fluid movements create a surge of ki, knitting your wounds together. When you activate Flurry of Blows, you may choose to spend one of your remaining Hit Dice to heal yourself as a free action. During one attack, you may use up to a total amount of Hit Dice equal to your Wisdom modifier. Once all of your Hit Dice have been expended, you cannot use this feature until you finish a long rest. 

Aspect of the Mountain: Imposing Presence

From 11th level, your disciplined form radiates confidence and prowess. You gain proficiency in the Intimidation skill. 

Aspect of the Valley: Song of the Nightingale

From 11th level, you may manifest your inner ki to quell the fear and rage of angered beasts. You gain the Animal Friendship spell, which can be activated by spending two ki points. When you use the spell in this way, the targeted animal has disadvantage on the wisdom save to resist your charm. 

Aspect of Heaven: Guided Strikes

From 17th level, your divine form strikes with lightning precision. Once per long rest, you can attune your soul to the heavenly planes, entering into a state of spiritual awakening. The following effects occur for one minute:

• You gain an additional 1d4 to attack rolls.
• When you successful land three attacks in a row on the same turn. your third attack becomes a critical hit. 
• Your attunement to the non-material planes allows you to alter your type of damage dealt between radiant, necrotic, fire, cold, thunder and acid. 
• When you reduce a small-sized or larger hostile creature to 0 hit points, you regenerate 1 ki point. 

 

Aspect of the Earth: Ward of Flowing Ki

Beginning at 17th level, your energy is entwined with the Material Plane. During combat, your AC is increased by the number of ki points spent during each turn. This additional defence lasts until the beginning of your next turn.
