Here, four monkeys in coloured robes share a health bar; you'll need to hunt them all down to finish the boss fight.
Sekiro: Shadows Die Twice - How to beat the Folding Screen Monkeys boss
Once you arrive at the Hall of Illusions, a short cutscene will show four screens, three of which depict one of the Wise Monkeys (see no evil, hear no evil, speak no evil, do no evil). These will be your foes in this unusual arena.
- The one in purple robes is the See No Evil monkey. It has very good eyesight, and will run away when it spots you.
- The one in green robes is the Hear No Evil monkey. It has very good hearing, and will run away when it hears you.
- The one in orange robes is the Speak No Evil monkey. If it spots you, it will alert the others, causing them to run.
- The last monkey, Do No Evil, is invisible, and will follow behind you.
Fortunately, all the monkeys have very little health, you just need to catch them. When you start, turn around and swipe with your sword to find the invisible monkey. If you lose track of him, use the Illusive Hall Bell to reset the positions of all monkeys. The invisible one should be right behind you where you start off.
The other monkeys are trickier to deal with. Your next priority should be the orange monkey, because being spotted by him will cause the other monkeys to flee. He patrols the rooftops, and you should be able to keep track of him by the orange footprints he leaves behind. You'll have to sneak up on him to take him down. If you have one, use a Gachiin's Sugar to improve your stealth.
The green monkey has very good hearing. Its normal position is at the very back of the level on a balcony. Because its eyesight isn't that great, you should be able to grapple towards it and kill it before it runs off. If you're struggling to catch it, though, you can make use of a huge bell near the far end of the area. This will deafen the monkey for a short time, making it a little easier to kill.
Finally, the purple monkey, which has great vision. Probably the hardest to sneak up on, but there is a way to deal with it. You should first find him in a hall in the back left of the level. You can approach from the roof and drop down, but he'll see you before you can get to him. Drop down anyway and open the door at the back of the room. This extinguishes all the lights in the room. Now you'll want to chase him around until he's back in his place in the now darkened area. Approach from the roof again, and you should be able to perform a vertical takedown.
Gachiin's Sugar is a very useful item for this boss encounter as it enhances your stealth abilities. It's also worth noting that more monkeys will spawn in and will chase you if they find you. It's important to avoid or kill these enemies as they will cause the Terror status effect, which is very bad news. And don't forget, if you lose sight of any of the monkeys, you can reset all their positions by using the Illusive Hall Bell item.
Once you've killed the four monkeys, you'll be transported to the Inner Sanctum and receive your rewards: the Screen Monkeys Memory, Puppeteer Ninjutsu move, and 3,000 XP.
