Way of the Vengeful Oni

Oni shit ya know the drill

Oni's Wrath

When you hit a creature with an unarmed strike, you may spend 1 ki point to deal extra necrotic damage equal to one Martial Arts die + your Wisdom modifier.

If the target is below its hit point maximum, the damage increases to two Martial Arts dice.

You can use this feature once per turn.

Additionally, you gain proficiency in Intimidation (or expertise if you already have it).

Demon Mask Stance

As a bonus action, you may spend 1 ki point to manifest a spectral oni mask and horns for 1 minute.

While this stance is active:

• Gain temporary hit points equal to your Monk level + Wisdom modifier.

• Your unarmed strikes deal necrotic instead of bludgeoning damage, if you choose.

• Gain advantage on Intimidation checks.

You can end this stance early (no action). It ends if you are incapacitated.

Oni's Assault

Your oni spirit drives relentless strikes.

• When you take the Attack action, you can make one additional unarmed strike as part of that action.

• When you use Flurry of Blows, you may add one extra unarmed strike beyond the normal number for 1 ki point.

Grasp of Vengeance

Once per turn, when you hit with an unarmed strike, you may spend 1 ki point to force the target to make a Strength saving throw against your Ki Save DC.

On a failure, choose one:

• Drag: Pull the creature up to 15 feet toward you.

• Crush: Knock the creature prone.

• Grip: Reduce the creature’s speed to 0 until the start of your next turn.

Large or larger creatures have advantage on the save.

Oni Resilience

While Demon Mask Stance is active:

• Gain resistance to necrotic and psychic damage.

• When you reduce a creature to 0 HP, regain ki equal to your Wisdom modifier (minimum 1).

• Your unarmed strikes count as magical and deal an extra Martial Arts die of necrotic damage once per turn.

Gate of the Vengeful Oni

You call upon the wrath of the oni spirits that came before you, opening a spiritual gate that unleashes their vengeance through your body.

As a bonus action, you may spend 6 ki points to summon the Legion of the Vengeful Oni for 1 minute.

Spectral oni spirits erupt around you—massive horned figures wreathed in crimson ki. They mirror your movements with terrifying force.

Oni Spirit Assault

For the duration, every time you make an attack roll with an unarmed strike, the oni spirits also lash out at your target.

• This occurs whether your attack hits or misses.
• The spirits deal 2d10 necrotic damage to the target.
• This damage happens once per attack you make.

If your attack hits, the oni spirits attempt to overpower the target. It must succeed on a Strength saving throw against your Ki Save DC or be knocked prone or pushed 15 feet (your choice).

Wrath of the Ancestral Oni

The spirits hunger for vengeance.

Whenever a creature takes damage from your Oni Spirit Assault, it becomes Marked by the Oni until the end of your next turn.

A marked creature cannot benefit from invisibility and cannot move willingly away from you without spending double movement.

If a marked creature drops to 0 HP, one of the oni spirits devours its rage, and you regain 2 ki points.

 

Terror of the Oni Legion

While this feature is active:

• You gain advantage on Intimidation checks.
• Enemies within 60 feet of you have disadvantage on saving throws against being frightened.
