Hollow Knight Silksong Pinmasters Oil Quest Guide
There are a few instances in Hollow Knight Silksong where it doesn't really feel like you can skip out on a side quest, but rather changes the way that you fight instead. One such instance is the Pinmasters Oil quest. At first, it will seem like nothing more than another odd thing to do within Pharloom's confusing questing system, but later, it gives you a huge boost in your fighting abilities. The item you're seeking, Pale Oil, isn't some additional crafting material. It's the secret to unlocking Hornet's weapon even more lethally, increasing her overall damage and making challenging battles a breeze. Gamers worldwide are searching for where the Pinmasters Oil is in Silksong, as it is longer and tougher than most of them expected. This guide will walk you step by step through the questline, what it unlocks in terms of regions, and ultimately, where you can obtain Pinmaste's Oil.
Beginning the Quest in Bellhart

Make Your Own game Server
As with most of Silksong's best side quests, Pinmasters Oil isn't one you get to early on. You first need to beat the Widow, a giant-sized boss who towers over Bellhart. The fight's not just one of reflex; it's one of doors. Once you've killed the Widow and repelled some of Bellhart's shadows, you'll notice new NPCs and quests open in and around the village. One of the inhabitants of these is Pinmaster Plinney, an expert craftsman living in one of the giant bells atop Bellhart. If you speak to him initially, he will hone your weapon slightly for you, but it is upon your second run out of his dialogue that the quest for Pinmasters Oil actually begins. He informs you that there exists a less familiar oil known as Pale Oil and that he requires it so he can unlock the maximum potential of Hornet's needle. This is the formal start of Silksong's Pinmasters Oil quest, and it sets you on a track not finished until very far into the midgame.
Why the Pinmasters Oil Quest is Important
Theoretically, the payoff is straightforward: Hornet's weapon will deal increased damage. But in practice, this single update changes the rhythm of combat. Normal mobs kill faster, killing elites less tiresome, and bosses, who survive on the model of blinding you with a health pool, die quicker. By the time you can afford buying the Pale Oil, you have likely had a few long boss fights where minor damage output enhancements would have taken you to a win and not the annoying loss. It is because of this that many players take the initiative to locate the Pinmasters Oil spot in Silksong as early as possible.
Becoming ready to progress to the Oil The most important thing to know is that you cannot buy the Pale Oil as soon as you start the quest. It appears only after you have reached far enough in Pharloom to unlock the Whispering Vaults. In the meantime, there are a couple of steps: Your first milestone comes in the Choral Chambers. Here, you’ll encounter the Cogwork Dancers, a unique boss that guards access to the next phase of the quest. Defeating them is mandatory, as the fight unlocks the route downward into the Cogwork Core. This area introduces more mechanical hazards and layered paths, but it’s also the key to breaking through toward the Vaults.
Once you're in the Cogwork Core, you'll finally find a switch that activates the machinery and opens the secret path ahead. This is one of those Silksong crossroads where exploration meets combat. Only by paying each room very close attention and utilizing the machinery will you discover the connection that gets you into the Whispering Vaults, the part of the level where the Pale Oil is finally stored.
Exploring the Whispering Vaults
Whispering Vaults are one of the more complex sections of Pharloom, with winding halls, secret rooms, and environmental problems. When there, it is highly advised to purchase a map of the section. It may be purchased by moving north from the entrance, then east into an ambush room where waves of mobs have to be battled. Once you've cleared that, the path ahead of you goes all the way to a room with the map to the Vaults. With it in your possession, searching for where you can find the Pinmasters Oil becomes a lot less stressful. As you progress further in, you will have a room off which has a puzzle that you will need to solve in order to continue. It is the main obstacle in your path, as well as that of the Pale Oil.
The Barrier Guarding the Pale Oil

The Whispering Vaults barrier puzzle is a series of mechanical chests that must be struck in an appropriate sequence to manipulate platforms and unlock gates. It is not such a complex puzzle in the game, but it might confuse players if they somehow skip a step or don't reset progress. The sequence unfolds across several small rooms: first striking a box against the west wall, then opening hidden passages upward, then carefully moving boxes to clear new paths. At one point, you’ll need to use wall jumps to reach a higher platform where yet another box is positioned, and striking it changes the arrangement of the chamber below. Piece by piece, the puzzle is uncovered, each hit box bringing you nearer to the chamber containing the Pale Oil. Once the final box is struck and the large obstruction is moved, the path straightens out. At the end of the corridor sits a silver lever. Pulling it opens a shortcut back to the Choral Chambers and, most importantly, reveals the Pale Oil itself resting on a pedestal. This is the moment you’ve been working toward, the discovery of the Pinmasters Oil location in Silksong.
Returning to Plinney
You now have Pale Oil. Your task is to return to Bellhart. Visit Pinmaster Plinney and present it to him. A cutscene will ensue as he applies the oil to Hornet's horn with the delicacy of one who has sharpened many blades in preparation. When finished, your weapon is changed forever. That increased damage isn't theory; you'll notice foes taking a quicker dip from the very beginning. This is also the true culmination of the Pinmasters Oil quest in Silksong. However, Plinney hints that possibly this story does not end quite here. He suggests there are possibly other sources of Pale Oil somewhere in Pharloom, and you're left to wonder about future upgrades, possibly in the pipeline if you look closely enough.
Rewards and Long-Term Impact
The instant benefit to the search speaks for itself: your needle does more damage now with the Pale Oil. There is a psychological advantage as well. Knowing your weapon has been blessed for good, you're less hesitant in going deeper into riskier territory. Pharloom's enemies just get nastier, and bosses will continue to demand cautious movement and stamina. Having the sharpened weapon from Pinmasters Oil ensures that you’ll spend less time chipping away at endless health pools and more time mastering mechanics and enjoying the fight. Aside from that, since this is literally one of the most uncommon quests in Silksong that directly influences Hornet's scaling on a personal level, it's really like an initiation. You do it knowing you've not only survived midgame, but also gained an item that will carry you through late game.

Final Thoughts
Where is the Pinmasters Oil? It's extremely heavily buried in the Whispering Vaults, after the Cogwork Dancers, the Cogwork Core, and a multi-step puzzle that will test your patience as well as your concentration. The Pinmasters Oil is not easily accessible, and you'll need to be dedicated to working your way through Pharloom in good detail before you can acquire it. But when you do, the labor is paid back with one of the most satisfying rewards in the game. If you want Hornet at her best, there is no skipping this quest. Pinmasters Oil in Silksong is not an improvement, ts a statement that you've come to master Pharloom's dangers and are prepared for the even more formidable dangers ahead.
