Onryoki (怨霊) is a Boss in Nioh. 


Onryoki is a giant red demon born from the amassment of vengeful spirits. Half its face is a burning flame of anger, while the other half is warped by grudge. Countless spirits give it an eerie appearance, and horrendous voices emit from its body. Most would want to avert their eyes from this horrid demon.


Pronounced "on RYO key." A huge red oni born from a pack of angry ghosts. Half of its face is contorted in anger, the other twisted with grudge. The faces of countless vengeful ghosts appear across its body, letting out shrieks that send terror down the spines of all within earshot.

Filled with fury and grudge, the sight of a living human sends it into a berserk rampage. Its preferred attack, using iron balls and chains draped over its body, is powerful enough to defeat even highly experienced samurai.

The two horns on its head emit a weird glow. It is said that horns represent the source of power for an oni, meaning they lose their strength if their horns are damaged. But only the most powerful and precise strike could hope to shatter them...

Strategy 1 (Melee)

Main Mission: Onryoki is a heavy hitter but moves slowly. The key is to stay behind him when he attacks, get your own damage in. Get in close to bait his attacks. When he spins his chain around, block to negate the damage. If you dodge instead you will get hurt. Keep putting his pressure on his back pocket in this way and he will go down. If you keep baiting him to swing his ball and chains wildly evenutally he will tire out and leave himself open for a barrage of damage.

In phase 2 he will break the chains and start throwing the balls at you. Simply stay as close to him as you can and attack. Be mindful because even without his balls, his close range attacks can hurt. This strategy works for both the fights in the Sub Missions

Sub Mission: The strategy for this mission is pretty similar to the Main Mission version. Repeat the same techniques of staying in his back pocket and block when he spins.


Strategy 2 (Magic)

A detailed Strategy goes here. It should feature details on the build, level and recommended weapons and items as well as counters for specific attacks.


Onryoki Twilight Strategy

The Blessed Village: The above melee strategy will work fine as his attacks remain mostly the same. However, in his first phase, he is able to link a Smash attack into a Spin attack with almost no delay. In his second phase his attacks again remain the same except for his Ball Toss. Instead of picking it up, turning, and then throwing the ball, he throws it along the floor as he turns. Try side-stepping as you see him bend down to pick up a ball.


Onryoki has two attack phases. In the first phase, Onryoki uses his weapon as a flail. The attacks are generally slow but have long range. Upon breaking his chains, Onryoki switches to his second phase where both his attacks and movement increase in speed. In addition, he'll throw his metal balls at William when given the chance.

First Phase
Smash Smashes iron ball to the ground directly in front of him. Sometimes followed by a second smash
Double Smash Rears back, then smashes down both iron balls directly in front of him. Long wind-up time gives plenty of time to dodge
Spin Spins weapons around him in a large, sweeping motion. Easily blocked if you have enough ki. Onryoki likes to do this when being attacked from behind, so keep on your toes
Swipe Swipes hand to the side. Uses this attack after getting knocked down, so don't get too aggressive
Second Phase
Fist Pound Smashes fist to the ground. Sometimes followed by a second smash if William is close
Jumping Double Fist Pound Jumps at William before smashing both fists to the ground
Flail Flails arms around before crashing to the ground. Excellent damage opportunity if you can bait out this attack
Swipe Swipes hand to the side. Uses this attack after getting knocked down, so don't get too aggressive
Backhand A quick backhand attack against anyone attacking his rear
Belly Flop Onryoki shows why he didn't make the dive team as he flops to the ground with all the elegance of a dump truck driving off a cliff
Ball Toss Picks up and throws iron ball at William. The direction of the throw doesn't always line up with the animation, so be careful when standing behind him as you can still get hit
Grab Grabs William, bites him, then throws him to the ground

      From my experience of several hours, I think I've got him down to a T.

      First phase, just rush near to him. He usually flings a ball (Right or left are possible) to the ground and is easy to side step and reach behind. You can strike IF you have a quick weapon with low stance, but do not greed. Always ANTICIPATE for a second attack after the first fling. He's more vulnerable after a second attack. You'll get the hang of the first phase soon.

      SECOND phase. The trick is to ALWAYS hug a wall on your LEFT and RUN to the RIGHT with a bit of BACKWARDS. If you do this, none of his attacks will hit. He has 2 attacks that summons Yokai realm, one is a single hit, other is a 3 hit combo. Single hit leaves him vulnerable for a short time, you can attack but don't greed. His 3 hit combo has black smoke around his hands so you'll know it's the 3 hit combo. This one you can do a full light attack combo and back off. Take it slow and keep kiting anticlockwise. Safest bet is to attack when he summons the Yokai realm.

        If you throw a rock at his face it will break his horns off and cause him to fall to the ground, opening him up for some attacks, careful though because he makes a forward attack when he stands up

          I assume the Bosses origin within japanese culture is derived from the concept of "Onryo" (d'uh) (see also: "Onryo" on Wikipedia).
          Quote: "In traditional beliefs of Japan and in literature, onryō (literally "vengeful spirit", sometimes"wrathful spirit" refers to a ghost believed capable of causing harm in the world of the living, harming or killing enemies, or even causing natural disasters to exact vengeance to redress the wrongs it received while alive then takes their spirits from their dying bodies."

          I'm not registered here, so please add ths assumption as trivia, if the rules of this page allow that.

            Fire was not super effective against this man. I should have tried other elements.
            I never checked if weapon buffs applied before entering the stage maintain once you enter.
            His attacks are easy to read once he reaches Stage 2, so play cautious and get behind him when able. Keep away from corners so you don't get stuck.
            If you run low on elixirs, check the crates and vases in the stage.

                He's weak to wind and water damage. Try to bait his forward ball toss in his first phase and his three swipe combo where he flops over at the second phase for some hits. Also use your living weapon ability. It just ATE his stam so I could stagger the***** out of him with my regular attacks.
