Some spool fragments become inaccessible after completing Act 2. We recommend collecting as many fragments as possible during your exploration of each area to avoid missing any for the "Extended" achievement.

Spool fragments and complete spool in Silksong showing silk upgrade system

What Are Spool Fragments?

Spool fragments are crucial upgrade materials in Hollow Knight: Silksong that increase Hornet's maximum silk capacity. Silk functions similarly to Soul in the original Hollow Knight, serving as the resource for Hornet's special abilities, healing, and various tools throughout her journey in Pharloom.

There are 18 spool fragments total scattered throughout the world, and every 2 fragments you collect increases your maximum silk capacity by 1 pip. This means you can gain up to 9 additional silk when you collect all fragments, effectively doubling your resource management capabilities.

Quick Reference:

  • Total fragments: 18
  • Upgrade ratio: 2 fragments = +1 silk capacity
  • Maximum bonus silk: +9 pips
  • Achievement: "Extended" (find all 18)
  • Availability: Acts 1 & 2 (6 in Act 1, 12 in Act 2)

Prerequisites & Collection Strategy

While some spool fragments can be collected early in your adventure, having the right abilities will make your collection much more efficient and allow access to all fragments.

Essential Abilities:

  • Cling Grip: Required for wall climbing to reach elevated fragments
  • Clawline (Grappling Hook): Essential for accessing many hidden locations
  • Faydown Cloak (Double Jump): Needed for several high-altitude fragments
  • Drifter's Cloak: Useful for gliding and avoiding hazards
  • Needolin: Required to access the Weavenest Atla secret area

Pro Tip: Many fragments are purchasable from merchants or obtained through quest completion. Prioritize these easier options before attempting difficult platforming challenges.

Advanced Collection Strategies

Optimization Routes

For efficient 100% completion runs, consider this collection order:

  1. 1. Early Purchasables: Bellhart (270 rosaries) - best value
  2. 2. Easy Access: Mosshome, Deep Docks lava chamber
  3. 3. Ability Gated: Weavenest Atla (after Needolin)
  4. 4. Collection Rewards: Flea Caravan (14 fleas)
  5. 5. Quest Chains: Whiteward Balm quest, Songclave merchant
  6. 6. Challenge Fragments: Deep Docks cave, Memorium last

Common Mistakes to Avoid

  • Don't attempt challenge fragments without proper abilities
  • Don't progress to Act 3 before collecting all accessible fragments
  • Don't spend all rosaries before securing purchasable fragments
  • Don't skip quest chains - many fragments are locked behind them

Audio-Visual Detection Tips

Spool fragments have distinctive characteristics that can help you locate them:

  • Glow with bright white light, visible from a distance
  • Emit a distinctive audio cue when nearby
  • Often placed in rooms that seem slightly out of the way
  • Look for breakable walls and secret passages

Troubleshooting Guide

Fragment Not Appearing

  • Check prerequisites: Ensure you have required abilities/keys
  • Quest dependencies: Some fragments require completing specific quests first
  • Area access: Confirm you can actually reach the location
  • Already collected: Check your silk capacity - it increases automatically

Platforming Challenges

  • Deep Docks cave: Practice Clawline timing in easier areas first
  • High Halls rings: Wait for ring rotation patterns before attempting
  • Memorium thorns: Use Drifter's Cloak proactively, not reactively
  • Whiteward elevator: Learn elevator timing by watching several cycles

Quest Chain Issues

  • Sherma not appearing: Rest at bench between quest steps
  • Jubilana missing: Complete Memorium rescue before she sells fragments
  • Flea caravan stuck: Need to enter Citadel to trigger relocation
  • Merchant not selling: Ensure you completed their specific quest requirements

Achievement: Extended

Collecting all 18 spool fragments unlocks the "Extended" achievement and maximizes Hornet's silk capacity with +9 additional pips. This dramatically increases your ability usage in combat and provides more frequent healing opportunities.

Base Silk: 6 pips Max Bonus: +9 pips Total: 15 silk pips
