Hollow Knight Silksong Flexible Spines Quest Guide
After defeating Lace in Hollow Knight Silksong, you drop into the Far Fields, an area full of lava, falling rocks, and strange wind currents. These updrafts can carry Hornet higher, but only after you upgrade your cloak. To unlock this ability, you must complete the Seamstress’s quest by collecting Flexible Spines. This guide covers how to farm Spine Cores quickly and finish the quest.
How to Start the Flexible Spines Quest
In the Far Fields, head to the hut in the eastern lava zone. Inside, you will meet the Seamstress. She offers to craft a new cloak that allows Hornet to float and ride wind currents. To complete her work, she asks for 25 Spine Cores.
Where to Find Spine Cores
Spine Enemies
Spine Cores come from floating spiked creatures found in a grassy cave near the Seamstress’s hut. When defeated, they explode and launch their spikes across the room. Each embedded spike can be broken to release a Spine Core.
Farming Strategy
Clear the cave of enemies, then break every embedded spike to collect Cores. If you run out, return to the Seamstress’s bench to reset the enemies and repeat. With efficient farming, you can collect all 25 Cores in just a few runs.
Reward: The Drifter’s Cloak
Once you return with 25 Spine Cores, the Seamstress upgrades Hornet’s cloak into the Drifter’s Cloak. This cloak lets you hold the jump button to float in mid-air. The ability slows your descent, helps cross large gaps, and allows you to ride updrafts in the Far Fields.
What Happens Next
With the Drifter’s Cloak, you can escape the Far Fields by riding currents back toward the Deep Docks or upward to Greymoor. Be prepared, though: the stone robot you passed earlier awakens once you return with your new cloak, forcing you into a fight before leaving the region.
Final Blurb
The Flexible Spines quest is the turning point of the Far Fields. Farming 25 Spine Cores may sound like a grind, but it takes only a few cycles in the grassy cave. Once complete, the Drifter’s Cloak gives Hornet the power to glide and ride wind currents, opening up Pharloom’s vertical routes and unlocking your escape from the lava-soaked zone.
