The Way of the Oni is a path for monks who seek to embody the fearsome power and unyielding strength of the mythical oni. Discarding traditional monk philosophies of inner peace and balance, these warriors embrace a ferocious and demonic physique. Their bodies become as tough as iron, and their spirits are fueled by the raw energy of their foes. Monks of the Way of the Oni are relentless combatants, their mere presence instilling terror in those who dare oppose them.

Demonic Physique

Discarding the flimsy traditions of the monks and pursuing the path of strength, your physique and techniques adapt to the new changes, hardening your body to a point even higher than the toughest of foes:

• While you not wearing armor or using a shield, your AC equals 10 + your Dexterity modifier + your Constitution modifier.
• You can choose to use your Strength or Dexterity modifier instead of Wisdom when calculating your ki save DC.
• Once per turn, you can roll one additional damage die when attacking with an unarmed strike.

Quick Movement

At 3rd level, once per round, you can expend one ki point to gain an additional reaction or bonus action.

Advance Footwork

At the 6th level, when a creature within 5 feet of you attacks, you can expend 1 ki point to increase your armor class by 2. If the attack misses, you can make an unarmed strike against that creature. If you successfully hit the creature, all attacks against it gain advantage until the beginning of the creature's next turn.

Oni's Rage

At the 11th level, you learn to steal the unused ki of others to keep yourself moving. Once per round, when you hit a creature with an unarmed strike, you regain 1 ki point. You can also choose to turn the stolen ki into unbridled power, dealing a bonus 1d10 force damage to the affected creature. Doing so prevents you from stealing more ki from the creature for 1d4 rounds. This damage increases to 2d10 force damage at 17th level.

Fist of Evil

At the 18th level, you embody the true power of the oni, gaining the following benefits:

• Your unarmed strikes use a d12 for damage
• As an action, you can expend 5 ki points to radiate an aura of fear and darkness within a 30-foot radius for 1 minute. All creatures of your choice within this radius must make a Wisdom saving throw against your ki save DC or become frightened of you for the duration. While frightened in this way, creatures take 2d10 psychic damage at the start of each of their turns. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
• As a reaction, when you are hit by an attack, you can expend 3 ki points to unleash a powerful counterattack. Make an unarmed strike against the attacker. If you hit, the attack deals an additional 4d12 force damage, and the attacker must make a Constitution saving throw or be stunned until the end of your next turn.
• As a bonus action, you can expend 5 ki points to imbue your next unarmed strike with anti-magic energy. If the strike hits, it dispels all magical effects of 6th level or lower on the target and in a 10-foot radius around it.
