Slitterhead has many unique aspects that bleed into its overarching narrative and gameplay, making for the perfect blend of weirdness that we can get behind. Even with all the glaring issues that hold it back from being truly remarkable, it’s still a fun, rewarding, and exhilarating experience if you can look past its shortcomings.

Here’s how to uncover even more of the facility’s mysteries in Slitterhead’s Jar of Poison RE (2nd Loop) mission!
Drifting Devil is a prime example that puts everything awesome about the game on full display, turning a boss fight mission into a bizarre and eerie experience. While the fight against Yin Yue is still pretty good, the other things surrounding the encounter is where it’s really at!
Starting Drifting Devil In Slitterhead
Unlike other boss encounter missions in Slitterhead, Drifting Devil does not lock the Primary Rarity slot, allowing you to choose both Rarities for the mission. We went with Edo and Anita, as they gel quite well together. Anita’s basic attacks become a chaotic blur of damage and speed when she activates Burning Edge, making her the obvious second choice here.
Despite making a solid choice for any mission, Julee cannot join you on this mission, so you better search for someone else you’re good with if you were expecting her to be able to tag along. If Anita or Edo isn’t your cup of tea, Alex, Tri, and Doni will also work relatively well here!
Defeat Yin Yue – Reef Stonefish Slitterhead: Phase One
As expected, the first phase of this encounter won’t be too complex, as Yin Yue will only have access to a few basic attacks. He will also have access to two unblockable and unparryable attacks, both of which are telegraphed with a bright red flash of light. He will charge straight at you if he’s far away from you. If he’s closer, he will perform a Lunging Strike.
His charging attack can be evaded by rolling to the left or right as he gets close to you or by switching to a different character that’s behind him. The Lunging Strike can be avoided by running away from him or by also jumping to someone else, not in the area.
From here, we strongly recommend using Edo’s Burning Edge and Angel Step combo to carve away at Yin Yue’s health, where he will eventually start summoning in lesser Slitterheads mixed in with little ones. When these Slitterheads enter the arena, focus them first, then go back to the same strategy until you drop his health past the first blip on his meter.
Chase Yin Yue
Getting Yin Yue’s health down past the first section of his health gauge will cause him to flee, having you chase him out onto the main street. Once you arrive, a brief cutscene will play, tossing you into the second phase of the fight.
Ensure you are healed up from the first phase before you begin your pursuit, or you will be off to a rocky start. This phase is the most challenging part of the mission and the encounter as a whole, so do not go in ill-prepared. Double-check if both of your Rarities are topped off before leaving the first area!
Defeat Yin Yue – Reef Stonefish Slitterhead: Phase Two
Right from the jump, there will be a standard Slitterhead and several lesser and little Slitterheads surrounding Yin Yue, making it a sea of chaos. Focus on the lesser and little Slitterheads first, as they don’t take long to defeat, especially when using Burning Edge, then turn your attention to the normal Slitterhead.
Some of the little Slitterheads have pustules on them, meaning if they attack you enough times, they can inflict you with Poison (Level 2), which is a potent Poison that will rapidly and aggressively deplete your health, so be wary of them. After taking care of all of the additional Slitterheads, turn your attention to Yin Yue.
He will have the same attacks as the first phase, so just activate Buring Edge and unleash your offense on him, dodging everything he throws at you just as you did earlier. Keep this up until you lower his health quite a bit, triggering a brief cutscene where he calls in more waves of Slitterheads.
Defeat The Waves Of Slitterheads
Upon summoning in waves of normal, lesser, and little Slitterheads, Yin Yue will leap back into the arena, ready to create even more damage to you. Like before, focus on the lesser and little ones first, then the normal ones, then Yin Yue. From here, go back into your offensive flow to deal considerable damage until he essentially flash-bangs you.
When Yin Yue illuminates with a bright white light, he will call forth more and more waves of Slitterheads, which will eventually get to a point where it’s unmanageable. At first, you should focus on the additional Slitterheads just as you did earlier, but you will ultimately have to focus all your efforts on him when things get too wild.
Whittling Yin Yue’s health down to the halfway point will have him run away from the area, leaving you with the remaining Slitterheads he summoned. Use Burning Edge to finish them off, heal up, and begin chasing after Yin Yue yet again, entering his third phase.
Chase Yin Yue Again
Replenish the health of both your Rarities, then begin chasing after Yin Yue, chasing him into the middle of the main street, where he will be waiting for you. Approach him to trigger another cutscene, kicking off the third phase of the encounter, which isn’t nearly as challenging as the previous one.
Defeat Yin Yue – Reef Stonefish Slitterhead: Phase Three
Phase three will have some lesser Slitterheads in the area, so focus on them first and eliminate them as fast as possible. From here, you will deal with Yin Yue the same way you did the previous two phases. This time, fortunately, his flash-bang attack that summons tons of Slitterheads is gone and has been replaced with a Blood Orb attack.
This attack has him spin several Blood Orbs in a circle in front of himself before launching them toward you with tremendous speed. You can either evade at the last second to avoid taking damage or switch to someone else entirely to have the CPU do all the heavy lifting.
Aside from this change in his move list, the rest of his attacks are the same from earlier phases, so pop Burning Edge and get up close and personal to destroy his health bar. Getting him down toward the last node in his health gauge will trigger another cutscene, pulling you into the Abyss.
Escape From The Abyss
Chipping Yin Yue’s health down to nearly the final node will have him drag you into the Abyss, which is a dark version of the facility. You will permanently have the Corrosion Ward (Level 3) and Stowing Ward (Level 1) ailments applied while in the Abyss.
Corrosion Ward (Level 3) substantially reduces your Blood Weapon’s durability, breaking it nearly instantaneously when guarding. Stowing Ward (Level 1) prevents you from evading and also reduces your attack and movement speed slightly. You won’t be able to use your Skills while here either, so be on high alert as you navigate through the darkness.
Fight Through The Abyss
Jump to your Rarity and begin navigating the tight corridors of the Abyss until you get ambushed by Yin Yue. While you can’t evade or use your Skills, you deal massive damage with normal attacks, so just get up close and start swinging to defeat him swiftly. Push slightly forward to fight a small group of lesser Slitterheads, hack away at them to eliminate them quickly.
The new area of the Abyss is more of the same, having you wade through tight hallways until you run into Yin Yue again. Deal with him exactly how you did earlier to warp to a new part of the Abyss. From here, follow the narrow corridors until you reach the Master’s Room, where Yin Yue is slumped over at the foot of the bed, snapping you back into the real world.
Defeat Yin Yue – Reef Stonefish Slitterhead: Phase Four
It’s time for this encounter’s fourth and final phase, which is more of a victory lap than anything, as Yin Yue won’t have much health left at all. He will teleport much more frequently and will launch Blood Orbs at you to try and keep you away from him.
Closing the gap on him will have him implement one final new move: the Blood Orb Field, having him summon many Blood Orbs around himself for a brief time before they detonate and deal substantial damage to anyone caught within it. When you see the Blood Orbs begin floating around him, create distance between you and him to avoid it altogether.
Your overall strategy here is to keep switching to your other Rarity whenever they’re behind him, allowing you to run up behind him and get several hits in before he focuses you. Activate Burning Edge to quickly stagger Yin Yue, then finish him off with a barrage of attacks to end this long-winded boss encounter!
Drifting Devil Rewards
Putting a stop to Yin Yue’s madness and clearing Drifting Devil for the first time will put a pretty hefty 24 Skill Tokens in your pocket for you to spend on any Rarity you feel deserves it. They are shared, so keep in mind that after you spend them, they cannot be used on another Rarity.
More ‘Talk’ dialogue conversations will unlock when defeating Yin Yue, so exhaust all of them as soon as you finish the mission to unlock the final stretch of missions available in Slitterhead. You’re almost there!
