100% Completion Checklist

What Counts Toward 100%?

Reaching 100% completion in Hollow Knight: Silksong requires collecting specific items and upgrades across Pharloom. Not everything counts — surprisingly, defeating bosses and completing Wish side quests don't directly contribute to the percentage, though many are prerequisites for items that do count.

Here's the complete breakdown of what contributes to 100%:

Tools Checklist (51% of completion)

Tools are by far the largest chunk of your completion percentage. There are 51 Tools in total, divided into three color categories:

• Red Tools — Active abilities requiring button input (projectiles, traps, summons)
• Blue Tools — Passive defensive/support benefits
• Yellow Tools — Passive exploration and utility benefits

Red Tools

Blue Tools

Yellow Tools

Note: This is a partial list of notable Tools. The full list of 51 includes additional Red, Blue, and Yellow Tools found throughout all areas of Pharloom.

Tip: Use the Compass Tool constantly while exploring to track your position on the map. It's one of the most essential Yellow Tools in the game.

Silk Spool Fragments Checklist (9% of completion)

There are 18 Silk Spool Fragments to find. Every 2 fragments add one notch to Hornet's Silk Spool, giving her more Silk capacity for Binding (healing) and using Silk Skills.

Crafting Kit & Tool Pouch Upgrades (8% of completion)

You need to fully upgrade both your Crafting Kit and Tool Pouch. These upgrades increase the number of Tools you can equip simultaneously and improve your crafting abilities.

There are 8 upgrades total:

• 4 Crafting Kit upgrades (increase crafting capabilities)
• 4 Tool Pouch upgrades (increase equipped Tool slots per Crest)

These are obtained from NPCs, quest rewards, and exploration finds throughout all three acts.

Weaver Skills Checklist (6% of completion)

6 Weaver Skills (also called Silk Skills) must be obtained:

Priority: Cross Stitch (parry/deflect) is the most universally useful. Get it as early as possible by clearing the Exhaust Organ in Bilewater.

Abilities Checklist (6% of completion)

6 Abilities are required for 100%:

Crests Checklist (6% of completion)

6 Crests to find. Crests determine your Tool loadout — each Crest has different colored slots for equipping Tools:

Note: The Cursed Crest and Witch Crest are connected. You get the Cursed Crest from Rite of Rebirth, then upgrade it to Witch Crest via Infestation Operation. For 100%, you need the Witch Crest.

Mask Shards Checklist (5% of completion)

20 Mask Shards are needed. Every 4 Mask Shards increase Hornet's health by one mask.

Needle Upgrades Checklist (4% of completion)

4 Needle Upgrades increase Hornet's attack power:

Needle Upgrades are obtained from specific NPCs and require Shell Shards as crafting materials.

Silk Hearts Checklist (3% of completion)

3 Silk Hearts are special collectibles that each add 1% completion:

These are found in specific late-game locations and often require completing quest chains to access.

Sylphsong & Everbloom (2% of completion)

• Sylphsong (1%): A special ability obtained during the Act 2 storyline
• Everbloom (1%): A unique item tied to the Act 3 storyline

Both are obtained through main story progression and cannot be missed if you're completing the full game.

Tips for 100% Completion

1. Buy every map from Shakra — Maps reveal area layouts and make finding collectibles much easier. Listen for her humming to find her in each region.

2. Equip the Compass always — Without the Compass Tool, you can't see Hornet's position on the map. It's essential for tracking your progress.

3. Complete Wishes for prerequisite items — Many Tools and Spool Fragments are locked behind Wish (side quest) completion, even though Wishes themselves don't count toward 100%.

4. Don't skip optional bosses — Several bosses drop Tools that count toward 100%. Missing a boss means missing a Tool.

5. Check every breakable wall — Pharloom is full of hidden chambers containing collectibles. Hit every suspicious wall.

6. Track your percentage in-game — Your current completion percentage is shown on the save file. Check it regularly to see how close you are.

7. Plan your Act 3 transition — Some items are only available in Act 3, while others become unavailable (like Garmond & Zaza). Plan accordingly.

Completion-Related Achievements

The Speed Completion achievement (100% under 30 hours) is tight but doable on a second playthrough. The Steel Heart achievement (100% in Steel Soul permadeath mode) is considered one of the hardest achievements in the game.
