Clawline, Silksong‘s harpoon dash, waits at a Weaver Burial Spire past a lava course in the central room of The Cauldron, in the Underworks. Two routes lead in, and only one needs a key: the White Key opens the lift down to Whiteward, while the lift that opens after the Trobbio fight needs none. Here’s how to get there.
Where Clawline Is
The Cauldron is the molten heart of the Underworks, and the ability sits at the Weaver statue beyond its lava gauntlet. You Bind at the Weaver Burial Spire to claim it, the same ritual as the game’s other Weaver abilities.
The Two Routes In
- Through Whiteward’s side passage: the route most players find first, threading from Whiteward into the Cauldron’s central chamber.
- The lift unlocked after defeating Trobbio: beat the performer and the lift opens a more direct descent.
Either works; take whichever matches your current map knowledge. The lava course past the entrance is the real test, a heat-and-timing gauntlet that previews exactly the kind of movement Clawline will trivialize forever after.
How Clawline Works
Fire the harpoon at a ring or an enemy and Hornet zips to it:
- Costs 1 Silk per throw, and the cost is refunded when you hit an enemy, which turns combat harpooning into a free repositioning engine.
- The rings scattered across Pharloom stop being decoration and become a transit network.
What Clawline Unlocks
This is one of Silksong’s great gatekeeping abilities:
- Mount Fay’s summit rings, and therefore the Faydown Cloak double jump, which in turn feeds Act 3; Clawline is the first domino in the endgame chain
- Dozens of ring-gated rooms, chests, and shortcuts across every earlier region; the post-Clawline backtracking lap is one of the game’s most rewarding hours
- A combat identity: harpoon-to-enemy into pogo strings is the flashiest, and frequently safest, way to fight airborne bosses
Frequently Asked Questions
Do I need a key for Clawline? Only on the Whiteward route: the White Key opens the lift down to Whiteward. The lift that opens after you beat Trobbio needs no key, and the Weaver Burial Spire itself has no lock. Your real obstacles are the route and the lava.
When can I get it? Once the Underworks and its approaches are open to you, mid-game; both entry routes are on natural progression paths.
Does Clawline work on all enemies? Ring-and-enemy targeting covers most combat scenarios; armored oddities aside, if it flies or hovers, you can harpoon your way to it.
Clawline or needle upgrades first? Both feed the same midgame spike; grab Clawline when you’re near the Underworks, and let the needle ladder follow your rosary balance.
