Unlocking Pharloom's Melodies: A 2026 Guide to All Six Psalm Cylinders in Hollow Knight: Silksong

As I retraced my steps through the opulent yet desolate kingdom of Pharloom in 2026, I realized that the Psalm Cylinders remain one of Hollow Knight: Silksong’s most elegantly buried secrets. These six enigmatic relics aren't just collectibles—they feel like fossilized hymns from a forgotten opera, each one carrying a fragment of the land’s silent anthem. Delivering them to Vaultkeeper Cardinius, a musical locksmith who sits amid the echoing Whispering Vaults, not only yields a tidy sum of Rosaries but also unravels a side melody that lingers after the credits roll. But finding all six is a delicate dance, so I’ve pieced together this guide to spare you the footwork.

The Psalm Cylinders: An Overview

There are six Psalm Cylinders in total. One—the Sacred Cylinder—is mandatory for advancing the main story by completing the Vaultkeeper’s Melody quest. The other five are optional treasures. Each additional Cylinder you hand to Cardinius is rewarded with 200 Rosaries, so collecting them all nets you 1,000 Rosaries. In 2026, with the game’s expansions settled, this remains one of the most efficient ways to stockpile currency for late-game purchases.

Where to Find Every Psalm Cylinder

🔍 1. Sacred Cylinder (Story-Required)

After defeating the flamboyant boss Trobbio, head right to unlock an elevator that descends into a previously inaccessible section of the Underworks. Continue right through a series of straightforward platforming challenges until you break through a path leading back to the Whispering Vaults. Activate the bench to your right, then turn left. Beside the corpse of a fallen Vaultkeeper, the Sacred Cylinder awaits—a somber note in Pharloom’s melody. Handing this to Cardinius pushes the main quest forward.

🔍 2. High Ledge Cylinder (Cling Grip Required)

From Vaultkeeper Cardinius’s position, walk right until you reach the room’s edge. You’ll spot a climbable wall. Use the Cling Grip (Wall Jump) ability to scale it. At the top, look to the upper-right corner—the second Cylinder rests on a narrow ledge, as if placed there by a mocking bird.

🔍 3. Air Current Cylinder (Drifter’s Cloak Required)

Descend into the maze-like section beneath the central Whispering Vaults. Navigate to the bottom of the room and strike the wooden box in the lower-left corner so it slides right. Climb onto it, then hit the box above to send it skyward. Wall-climb up to that elevated box, then jump to the right to discover a hidden tunnel. Inside, unlock an air current. Equip the Drifter's Cloak and ride the updraft to the summit of the Whispering Vaults. Head left to enter a chamber housing the third Cylinder. Pull the nearby lever to open a shortcut back.

🔍 4. Grindle’s Expensive Cylinder (Faydown Cloak Required)

In the Blasted Steps area, the mischievous thief Grindle will sell you a Psalm Cylinder for 240 Rosaries. You’ll first need the Faydown Cloak (Double Jump) to reach his shop. Once you’ve acquired that ability, make your way to the marked spot on the map—a precarious ledge overlooking the rust-colored chasms—and trade coin for cylinder.

🔍 5. Unravelled Path Cylinder (Surgeon Key Required)

After obtaining the Surgeon Key from Whiteworks, you’ll unlock the confrontation with the Unravelled boss. Defeat this twisted foe and a passage opens to the right, leading down into the Underworks. Immediately after dropping down the first shaft, turn left. You’ll notice a breakable wooden wall that sounds hollow when struck. Smash it open to claim the fifth Psalm Cylinder.

🔍 6. High Halls Pilgrim Cylinder

Upon entering the High Halls, proceed to the spot where a pilgrim’s corpse lies draped over a ledge. This cylinder can be seen from above but is impossible to grab directly. Instead, drop from the ledge beside the entrance into the water below, swim left, then use Cling Grip to climb up the left-hand wall. This roundabout route delivers you right next to the corpse, where the final Psalm Cylinder sits.

Completing the Melody

Handing all six cylinders to Vaultkeeper Cardinius feels like finally assembling the scattered notes of a ghostly symphony—each relic a key change that deepens Pharloom’s hidden lore. In 2026, many players overlook these secrets behind breakable walls and acrobatic leaps, but with this guide, your Rosary purse will bulge and the Vaultkeeper’s tune will finally harmonize. May your silk thread never fray.

Once the Vaultkeeper’s melody finally rings true across Pharloom, there’s a certain bittersweet feeling—the hunt is over. But for collectors, the thrill of the chase doesn’t end with one game. New Metroidvanias and soul-likes are always on the horizon, and the savvy player knows that a well-timed purchase can be just as satisfying as a well-timed dodge.

Rather than checking store pages every morning, you can set up this price tracking tool to do the legwork for you, alerting you the instant a wishlisted title hits its lowest price. That way, when the next big adventure calls, your Rosary purse—and your real one—will stay nicely bulging.
