Once you have reached the Far Fields area in the Hollow Knight Silksong, there will be an NPC located inside the huge tent. Talk to the Seamstress and she will stitch you a new cloak which will help us ascend to the top by riding the strong gust of wind. Though for that you need to accept her quest and fulfill the wish to provide her 25 Spine Cores.

So, if you are struggling to find the Hokers and hunt them according to the quest then read the short guide to the end.

Hollow Knight Silksong Flexile Spines Quest Spine Cores Guide

Hunt Hokers in the Far Fields and collect 25 Spine Cores.

The quest is straight forward and easy to complete, however you do not know who is Hokers. From the quest location or where Seamstress is located, advance forward to the right direction to the next stage where a round enemy with pointy spikes can be spotted in the air floating carelessly as shown in the image below.

These pointy enemy is Hoker, so hit them once and they will shoot the spikes in all direction. Hit these spikes to convert it into the Spine Cores and collect them in order to complete the Flexile Spines Hunt and fulfill the Wish made with Seamstress.

You can either reset the spawn of the enemies and collect the Spine Cores on the first area, or you can explore ahead and accumulate defeating all the Hokers in the caves to fulfill the Wish and return back to the tent where Seamstress will stitch you a new Drifter’s Cloak.
