What to know
- Completion is revealed only after obtaining and installing the Farsight; plan for a late-game check.
- The completion meter is broken into categories (tools, skills, upgrades, masks, spools, etc.) — each category lists exact counts and percent weight.
- Tools (the “Arsenal” requirement) are the single biggest chunk of completion; collecting every unique Tool is required.
- Most collectors use the in-game Farsight plus guides like this for locations and missables.
Reaching 100% completion in Hollow Knight: Silksong is a demanding but rewarding task. The game doesn’t reveal your progress until late in the journey, and the requirements spread across multiple categories. With so many collectibles and upgrades hidden in corners of Pharloom, planning your run is essential. This guide breaks down every category, shows how much each contributes to the total percentage, and explains how to tackle cleanup efficiently.
The full 100% breakdown by category

The completion percentage is divided into several parts. Each item, upgrade, or collectible contributes to the total.
| Category | What it includes | Count | % of total |
|---|---|---|---|
| Tools (Arsenal) | Every unique Tool and its variants | 51 | 51% |
| Silk Skills | Bindable Silk abilities | 6 | 6% |
| Upgrades | Crafting Kit & Tool Pouch | Full set | 8% |
| Silk Hearts | Rewarded by major bosses | 3 | 3% |
| Crests | Equipable crests | 6 | 6% |
| Abilities | Core movement and combat skills | 6 | 6% |
| Mask Shards | 20 shards (5 full masks) | 20 | 5% |
| Silk Spools | 18 fragments (9 upgrades) | 18 | 9% |
| Needle upgrades | Progressive weapon improvements | 4 | 4% |
| Miscellaneous | Quests, Fleas, maps, Bellhome unlocks | Several | 2% |
Tools: The biggest requirement

The Arsenal represents over half of your completion percentage. Every Tool must be obtained, including variants tied to choices or repairs. Some are sold by vendors, while others appear in hidden corners or as quest rewards. Tools are by far the most time-consuming part of completion, so they should be your highest priority when planning a 100% run.
Silk Skills (bindable abilities)
Six Silk Skills must be found and bound at their relevant locations (often after beating specific phantoms or bosses). These are: Silkspear, Thread Storm, Cross Stitch, Sharpdart, Rune Rage, Pale Nails. Silk Skills are straightforward to track once the Farsight is installed.
Upgrades: Crafting Kit & Tool Pouch

Tool Pouch upgrades (increase shard capacity and tool ammo) and Crafting Kit upgrades (boost tool effectiveness) are scattered and sometimes given as quest or minigame rewards. Completing the full set of these upgrades contributes a discrete portion of completion.
Silk Hearts, Crests, Abilities, Needle upgrades

- Silk Hearts: Three special hearts usually tied to boss encounters.
- Crests: Claim all six crest types.
- Abilities: Get every movement/utility ability like Silk Soar, Needolin, Needlin, etc.
- Needle upgrades follow a multi-stage upgrade tree requiring boss drops and crafting materials. Each of these categories is individually tracked in the completion menu.
Mask shards and Silk Spools (the “resource” collectibles)

- Mask Shards: 20 total (five upgrades of 4 shards each) that increase max health.
- Silk Spools: 9 silk upgrades requiring 2 spool fragments each (18 spool fragments total).
These are common “cleanup” targets — many are hidden in small optional areas.
Miscellaneous completion flags
Rescuing fleas (30 total), opening all Bellways and Ventrica Stations, getting maps of every area, completing certain NPC wish lines (Bellhome unlock, Everbloom), and binding particular NPCs all appear under “miscellaneous” and achievements. They’re each single flags but collectively important.

Individually these give only small percentage boosts, but missing even one will prevent 100% completion.
How to plan a 100% run
Planning in advance saves duplicate runs and back-tracking. Follow the steps below when preparing for a completionist playthrough.
Step 1
Finish the story to the point required by progression gating (many 100% flags require Act 2/3 content). The Farsight (see below) is a late-game unlock; plan to do a cleanup pass once it’s available.
Step 2
Build or grab a checklist or interactive maps. Use them to mark missable options, quest flags, and vendor-only Tools.
Step 3
Prioritize category big hitters: All Tools first (Arsenal), then Silk Spools / Mask Shards, then skills and upgrades. Collecting Tools early reveals which areas require revisits.
Step 4
Reserve a dedicated cleanup run after obtaining the Farsight and unlocking your Bellhome — the in-menu percent will show precisely what’s missing. If possible, keep one save slot for completion runs.
How to collect every Tool (Arsenal) efficiently
Tools are the largest single category. The following method minimizes repeated exploration.
Step 1
Tackle region clusters rather than item types — clear one zone fully (maps, shops, benches) before moving on. Use teleport networks (Bellways) to minimize backtracking and note which vendors sell unique Tools.
Step 2
Prioritize Tools that require a choice or a repair (e.g., Silkshot variants) — if a Tool is offered as a mutually exclusive repair choice, decide early — find alternatives if the game supports multiple versions by separate repairs.
Step 3
Use Tool Pouch upgrades (capacity) and Crafting Kit upgrades as they appear; they make later arena/gauntlet bosses and long fetches less punishing. Collect Tool Pouches early when possible.
How to find Mask Shards and Silk Spools without endless grinding
Mask Shards (20) and Spool Fragments (18) are common collectibles that sit in small optional rooms; their distribution is predictable.
Step 1
Prioritize completing all area maps and speaking to map merchants — maps reveal likely hidden alcoves and make arcane platforming puzzles easier to return to.
Step 2
Run region sweep: every map area has 1–3 small side niches. Use a checklist to mark every “4 shards = 1 mask” cluster so progress is visible.
Step 3
For spool fragments, search vendor/mini-quest rewards and boss rooms; some fragments are reward flags for NPC wishline completions rather than raw exploration. Keep track of wishboard rewards.
How to unlock Bellhome, assemble Farsight, and show completion
The game deliberately hides the completion percent until late in the game — the Farsight is the on-device that unlocks the readout in menus; it must be assembled in your Bellhome.
Step 1
Unlock a Bellhome by completing Bellhart wishlines (Bellhart’s Glory and related quests) or by meeting the donation/quest threshold; obtaining the Bellhome Key opens your home.
Step 2
Venture into the Abyss (Act 3) to find the Farsight in a guarded chamber (you’ll need traversal skill). Collect the Farsight item.
Step 3
Return to Bellhart and assemble the Farsight in your Bellhome; once assembled the menu will expose completion percentages and the breakdown by category — use it to plan targeted cleanup runs.
How to handle achievements, trophies and the “100% + speed/Steel Soul” variants
Silksong includes both platform achievements and platform trophies; some relate to finishing with 100% (and some to doing so under constraints like time or permadeath).
- The game’s achievement set includes completion (100%), speed completion (100% under 30 hours), and Steel Heart (100% in Steel Soul). Platform trophy counts differ (PlayStation has 34 trophies total). Use the in-game completion flag plus achievement/trophy pages for platform-specific tracking.
- 30 hours is the new benchmark for a 100% speed completion (up from 20 hours in the original Hollow Knight), which signals a significantly larger scope. That’s a useful benchmark for planning speed/achievement runs.
Practical cleanup checklist (final run)
- Install Farsight and open the completion menu; list missing items per category.
- Prioritize all Tools that are still missing (highest % impact).
- Sweep for Mask Shards and Spool Fragments by region.
- Finish all Wishboard/NPC quest flags (Bellhome, Everbloom, Fleas).
- Confirm Silk Skills and Crests are all bound/claimed.
- If chasing the speed/Steel Soul trophies, plan a separate run; attempting both 100% and permadeath in the same run is high-risk.
Completing Silksong fully
Reaching 100% in Silksong is a true completionist challenge. Tools dominate the process, but shards, spools, upgrades, and NPC quests all play critical roles. Once the Farsight is assembled, missing items become easy to track. With patience, a reliable checklist, and region-by-region sweeps, the climb to 100% completion turns into a structured and rewarding journey through Pharloom.
