Onryoki (怨霊鬼) 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)

Generic advice

  • He has high defense. Attack buffs and defense debuffs are very useful. For example, power pill + weaken talisman
  • A ranged attack can break his horn, stunning him. This gives you a short window to attack, and he will do a swipe after he recovers, so it is  not that useful.

Phase 1

  • The key get in front of him, dodge towards his back, hit, and repeat.
  • When he spins his chain around, block to negate the damage. The spin is hard to dodge at close distance, as it has 2 hits. But if you are far away you can just move backwards.
  • It is generally better to bait his frontal attack by getting in front, then get to his back. If you stay at his back the whole time, he spins a lot, which is harder to evade

Phase 2

  • The ball throw is unblockable. It is easy to predict,  as he will move towards his balls.
  • If you stand behind him, he will do a spin attack you can block. If your block is weak, this will break your guard, so staying behind the whole time is not useful. But, if your guard is good, you can just get behind, hit, block the spin, and repeat til dead
  • If you can't block the spin, get close to his legs, either next to the crotch or at his flank. In this position you can dodge almost everything, and he will not spin.
  • If he runs out of ki, he will do a belly flop. If you are sticking to his legs, run away or it will kill you




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 insane 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 the player and smashes both fists into the ground.  Creates a yokai realm on impact.
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 Does a quick belly flop that releases a small shock wave.  Gives the player a good opportunity to deal damage.
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

      for anyone who has trouble with this guy, try using the kusarigama and pick up the skill summer twilight, this is a huge damage buff thats way better than power pill, also you wanna not wear any armor as wearing armor will reduce your damage by a ton, use weakness talisman on him, and you wanna use living weapon, optimally you wanna pick kato at the start since hes the best spirit, if you do all that he dies in 3 heavy attacks to the back, you wanna aim for the back, because that will give you alot of bonus damage, its basically every bosses weakpoint, similar to the head in monster hunter.

        Funny how this boss made me stress up for an hour in one day to going through a intense research on how to counter him and reset my equipment a bit to fit him on the next day. Then I easily finished him on first retry. Onmyo Magic for phrase one, Devigorate Talisman to reduce all his melee damage to very weak attack in majority of Phrase 1 while using Blinding Shell from ninja skill to make him toss like a idiot in Phrase 2. All you need to do is keep him near the iron ball and he likely to used his faulty range skills. Poison coating not requirement.

          recommended level 5????

            His first form(with the balls) is significantly harder than the second in my opinion. Two tips: Get him down too his second form ASAP with breaking the horns and using Living Weapon. Don't waste healing items before form 2. If you die in form one, just accept it and run back. Form 2 is at 25% down, so not that hard to get to.

              His boulder throw should have you dodging. He can somehow throw the thing clean through his legs to hit you if you're on his backside

                I have tested amrita and gold drop by fighting without any equipment that will increase amrita or gold earned from the boss. amrita earned : 2700 Gold earned : 320 This is just a guessing, may be the amrita and gold earned increase or decrease depends on how many times you encounter the boss \\ NOTE: You can trigger the second phase before reaching half its HP by hitting its horns

                  Get near him, back up when he attacks. Hit him twice or somthing right after. If you can bait his vertical swings, you don't have to wait for the combo to end, just keep moving to the side. He won't turn well while swinging. He will often counter with a spinning combo if you are flanking him, so backing up is good. After his counter, you can rush in and chip at him again, then back off. You need some timing to dodge his throw move. Dodge too early and you are hit. There is merit to aiming for his head, maybe throw something or hit him when he slams. You can stun him for a while if you damage his horns enough.

                    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.

                            when i managed to poison him it was ticking 110 damage every second so i believe hes weak to that. my friend and i managed to stun lock him with out guardian spirits (mine being mizuchi and his was daiba-washi)

                              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.

                                This *****er is the hardest boss in the game and they decided to make him the first one. I think it killed me 8 times during the twilight mission :/
