Use the central shaft and the long Craggler room to orient yourself, then return for Clawline- and wish-gated rewards when you have the right progression.
How do I get through the Wormways?
Wormways lies west of Bone Bottom. Both entrances branch off the cavern leading toward Blasted Steps. Choose your route based on what you have unlocked and where you want to go; neither entrance is universally best. The community-maintained Wormways area reference describes the connections and landmarks below.
| Route | Requirement and approach | Connection |
|---|---|---|
| Southern entrance | Reach the room directly left of Mosshome; Swift Step is typically needed to cross to the entrance. A Simple Key door west of the Craggler room blocks the southern route into the main area. | Enters from the lower side of Wormways and leads through the Craggler room toward the central shaft. |
| Northern entrance | Enter from Shellwood. This route avoids the Simple Key door on the southern route. | Connects into the Wormways tunnel network and provides access toward the area’s northern connections. |
Finding the southern entrance from The Marrow
- Start at The Marrow Bellway and go left through Mosshome.
- Drop down beyond the pilgrim enemies, then continue left above Bone Bottom.
- Use Swift Step to cross to the hanging cage. Avoid the acid-spitting bug on the approach to the door.
- If you need the early Simple Key, Pebb sells one in Bone Bottom for 500 Rosaries, according to PC Gamer’s southern-route walkthrough.
Orienting yourself inside
The lower entrance opens into a long, horizontal room with Cragglers. A central utility shaft, patrolled by Winged Pilgrims, separates the entrance routes from the main tunnels. Its bottom trapdoor unlocks from above, so if it will not open from where you are, look for the route that reaches the shaft from higher up.
The branch by the key door connects down toward Bonegrave and up toward Shellwood, giving you a way to reach Bellhart by the alternate route. Tight passages, spike pits, and burrowing enemies make careful movement more reliable than rushing. Shakra’s in-game description, transcribed by the community wiki, calls the caverns “Worm-ridden caverns, shaking and unstable” and notes faint signs of former pilgrim travel.

Where are the Wormways map and collectibles?
Use the in-game map to track explored rooms; the area’s branching passages are easier to follow by landmarks than by assuming a fixed screen position. The reference lists these area completion targets and reward conditions:
| Find | Location or condition |
|---|---|
| Flea | One listed in Wormways. |
| Mask Shard | One listed in Wormways. |
| Memory Locket | One listed in Wormways. |
| Frayed Rosary String | One listed in Wormways. |
| Beast Shard | Dropped by a Craggler. |
| Dead Bug’s Purse | One listed; replaced by a Shell Satchel in Steel Soul mode. |
| Lifeblood Cocoons | Three are listed; two are available only in Act 3. |
Wish-gated Plasmium materials
Plasmium is not a permanently available pickup: it appears only while the Alchemist’s Assistant Wish is active. Plasmified Blood is obtainable only during Alchemist’s Assistant or Advanced Alchemy. In the lab toward the north of Wormways, Zylotol gives a Plasmium Phial for completing Alchemist’s Assistant and a Plasmium Gland for completing Advanced Alchemy. If you are clearing the area between those wish states, plan to revisit rather than treating the missing material as a missed ordinary collectible.
Rank #2
- Hollow Knight: Silksong is the epic sequel to Hollow Knight, the award winning action-adventure.

How do I reach Weavenest Karn?
Weavenest Karn is at the far left of Wormways. Its elevated entrance requires Clawline. The sub-area is a platforming challenge that ends at a Weaver Burial Spire, where Hornet can bind the Sharpdart Silk Skill.
What changes in Act 3?
Act 3 transforms much of Wormways through Zylotol’s Plasmium experiments, with the biggest changes on the western side. The eastern portion remains mostly as it was in Act 2.

Common named enemies include Groms and Gromlings, Aknids, Pilgrim Hornflies, Winged Pilgrims, Winged Pilgrim Bellbearers, Overgrown Pilgrims, Cragglers, and Cragglites. Act 3 adds Plasmidas and Plasmids. The area reference states that all enemies in Wormways are immune to black-threading, so do not build a combat plan around that effect here.
