Flexile Spines Wish

The Flexile Spines is not just a side quest; it is a mandatory main story quest in Hollow Knight: Silksong. Given by the mysterious Seamstress in the Far Fields, this hunt tasks you with gathering a special material to craft the Drifter’s Cloak—an essential ability for progressing through Pharloom.

Your journey to find the Seamstress begins after defeating the boss Lace in the Deep Docks. Use the map below to pinpoint the Seamstress’s house and the Hoker farming area.

  1. After the Lace encounter, proceed to the right to enter the sprawling Far Fields region. This area is filled with new, challenging enemies, so be prepared.

  2. Continue heading east until you reach a very tall, vertical corridor. Your goal is to head down. Take the lowest possible path that continues to the east. You’ll know you’re on the right track when you have to cross a series of small stone platforms over lava.

  3. In the next large room, carefully drop to the bottom, avoiding the large enemy that performs a flurry of attacks. Cross to the right side of the room and begin climbing up the platforms. Make your way back towards the left at a higher elevation to reach the large wooden platform suspended in the center of the room.

  4. Enter the large building on this central platform. Inside, you will find the Seamstress. Speak with her. She will offer to craft a special cloak for you if you bring her 25 Spine Cores from creatures called Hokers. Hornet standing in front of the Seamstress.

With the quest in your log, it’s time to hunt. The process for collecting Spine Cores is unique and requires a specific technique.

  1. Exit the Seamstress’s house and head to the right. Take the exit that leads into a grassy cave area. Here, you will find bug-like creatures with spikes on their backs—these are the Hokers. Hornet standing next to a Hoker enemy in the grassy caves of Far Fields.

  2. Simply defeating Hokers will not yield any Spine Cores. The method is more specific:

    • First, strike a Hoker with your Needle.
    • The Hoker will retaliate by shooting its spikes out in the direction it is facing.
    • These spikes will embed themselves into any surface they hit (walls, floors, platforms).
    • You must then strike the embedded spike with your Needle.
  3. When you successfully strike an embedded spike, it will break apart and release a glowing Spine Core. Quickly pick it up before it disappears. Repeat this process until you have gathered all 25.


Once you have all 25 Spine Cores, return to the Seamstress. Hand them over, and after a short cutscene where she crafts your new gear, you will be rewarded with the Drifter’s Cloak.

  • Ability: Drifter’s Cloak
  • Effect: Allows Hornet to float and slow her descent by holding the JUMP button while airborne. Most importantly, this ability allows you to ride on updrafts (currents of wind) to be carried to much higher platforms and previously inaccessible areas.
