Hornet’s quest to carry more silk in Hollow Knight: Silksong is less about needlework and more about hoovering up every shiny Spool Fragment hidden across Pharloom. There are 18 of these little upgrades, and grabbing all of them isn’t just satisfying for pack rats—it unlocks the Extended achievement. Players who ignore them will spend the late game with a very modest silk pouch, which is basically like bringing a teaspoon to a soup festival.
The hunt spans cramped chutes, locked gates, suspicious vendors, and one particularly unhinged elevator. Since the 2026 completionist scene has already mapped every corner of Pharloom, this guide lays out each fragment with just enough sass to keep the pain tolerable.
? Bone Bottom and the Marrow Wall
The first fragment waits in an alcove above Bone Bottom. Players should trace a path that briefly skims the left side of the Marrow before smashing a wall at the marked spot. It’s a gentle introductory hide-and-seek, assuming a wall doesn’t count as a hiding spot.
?️ Weavenest Alta
After unlocking Needolin, players can open the locked gate on the right side of Mosso Grotto. Weavenest Alta sits beyond that gate, and the route to the fragment is a silk-spun reminder that ability gating waits for no one.
⚓ Deep Docks
Deep Docks offers two fragments. The first sits at the top of a room with a floor made of embers, which sounds more like a hazard warning than a landmark. Follow the route to reach it.
The second requires one of Pharloom's Simple Keys. Unlock the door in Deep Docks, traverse the area beyond, and the fragment appears along the route. Compared with the ember floor, this one is practically a shopping trip—except the door insists on a key.
?️ Greymoor
A high alcove in Greymoor holds the next fragment, and reaching it is a straightforward climb for anyone who remembered to look up. The route makes it painless.
? Bellhart and Blasted Steps (The Rosary Economy)
Not every fragment is found in the wild—some are bought. In Bellhart, players must complete the My Missing Courier Wish from the Wish Board, then pay Frey the vendor 270 Rosaries for a fragment.
In the Blasted Steps, Grindle sells one for 680 Rosaries, which is roughly the in-game equivalent of highway robbery. But the Extended achievement doesn’t care about financial fairness.
? Grand Gate, Lost Fleas, and Scale Rooms
After finding 14 Lost Fleas, players can speak with Flea Master Mooshka to earn a fragment. The Flea Caravan should be hanging around between the Blasted Steps and Grand Gate at this point. Then, climbing to the top of the Grand Gate’s scale room yields another fragment. It’s a two-for-one district for anyone with a fondness for fleas and heights.
? Choral Chambers / Songclave
The Lost Merchant Wish, completed in Songclave, unlocks the chance to buy a fragment from Jubilana for 500 Rosaries. Separately, the Balm for the Wounded Wish from the Songclave Wish Board rewards a fragment outright. The NPCs here are generous, provided players enjoy running errands first.
⚙️ Cogwork Core and The Slab
A fragment sits in the bottom-right corner of Cogwork Core, nestled among the machinery. Another fragment is technically on the right edge of Mount Fay but is accessed by following a route through the Slab. It’s one of those “location vs. access route” debates that mapmakers love and players endure.
? Underworks and Whiteward Elevator Chaos
The Underworks contains two fragments. The first is in a room just beneath the area's elevator. The second sits on the right side, but the route is a long detour through Cogwork Core and the Whispering Vaults. Starting from Songclave, players follow the path until an alcove at the bottom of the final chute. At least the scenery is consistent: tunnels, cogs, more tunnels.
Whiteward's fragment, however, is a masterclass in elevator trolling. It's at the bottom of the elevator chute, and the only way down is to outsmart the elevator itself. The sequence goes: ride the elevator to the bottom, take the long way back to the top without using it, stand on the button to summon the elevator, quickly fall into the chute and slip onto the midpoint path as the elevator passes, then fall to the bottom to claim the fragment. It sounds like an escape room designed by a vengeful architect.
? Memorium and High Halls
Once double jump is available, players can reach the Memorium area and follow the route to grab a fragment. Finally, starting from the bench in the top-left corner of the Choral Chambers, a path leads to the 18th fragment at the top of High Halls. That bench-to-summit stroll is a gentle way to end a hunt that has involved fleas, wish errands, deadly embers, and one extremely passive-aggressive elevator.

Collecting all 18 not only maxes out Hornet's silk capacity, it also pops the Extended achievement. The real reward, however, is never having to revisit Whiteward's elevator experiment—until the next playthrough, naturally.
For completionists who have now secured every fragment and maxed out Hornet's silk capacity, the hunt itself often sparks an appetite for more games in the same vein. Metroidvanias with this level of intricate world design are rare, and tracking down the next great adventure can be just as tricky as finding a hidden alcove in the Underworks. Whether you're eyeing a new release that builds on this genre's best ideas or waiting for a classic to go on sale, knowing the right moment to buy can save you a bundle in the long run.
That's where checking a game price tracker comes in handy. Much like mapping out a route through Choral Chambers, a little strategic planning before a purchase can help you secure the best price across multiple storefronts, so your wallet stays as intact as your save file. After all, the only thing more satisfying than a 100% completion screen is knowing you didn't overpay to get there.
