Hollow Knight Silksong Mask Shards — All 20 Locations

Mask shards are the upgrade you feel in every fight: gather four and one of Hornet’s masks is permanently extended. Twenty shards are hidden across Pharloom, and this guide lists every one of them by act — with the region, how to reach it, and how risky it is to leave for later.

Every row deep-links into the Silksong interactive map (region filter plus the exact marker), and the three shards worth a deliberate detour before Act 3 are flagged below.

Silksong mask shards in order

The tables group all twenty shards by the act in which their region first opens. Treat that as a routing order, not a hard gate: once a region is open, its shards are yours to collect whenever you like.

A practical habit is to sweep each region for shards on your first pass, then re-run the sweep after Act 2 opens the Citadel. If you left a region one shard short, the map filter below re-opens the hunt in a single click.

Act 1 — 11 mask shards — Moss Grotto, The Marrow, Deep Docks, Far Fields, Hunter's March, Greymoor, Bellhart, Shellwood, Blasted Steps
Act 2 — 7 mask shards — Bilewater, Wormways, Sinner's Road, The Slab, Whiteward, Choral Chambers
Act 3 — 2 mask shards — Verdania, The Underside

Mask shards to grab before Act 3

No shard is permanently story-gated, but three placements deserve a deliberate detour — two because Bilewater is easy to route around entirely, and one because of where it sits inside The Slab.

Mask Shard 12 — Bilewater^*
Bilewater routing is easy to skip; mark the pin once the region map is bought.
Mask Shard 13 — Bilewater^*
Adjacent to the secret bench — pairs naturally with the P3-1 bench long-tail.
Mask Shard 16 — The Slab^*
Reachable only during or shortly after the escape sequence — verify whether it stays available afterwards.

Everything else stays collectible in any act. If you reach Act 3 short a shard or two, work through the act tables top to bottom with the map filter open.

FAQ

▸How many mask shards are in Silksong?

Twenty. Every four mask shards forge one extra mask of health for Hornet, so the full set grants five bonus masks on a completed save.

▸Where are the mask shards in Act 1?

Act 1 holds eleven shards spread across Moss Grotto, The Marrow, Deep Docks, Far Fields, Hunter’s March, Greymoor, Bellhart, Shellwood and the Blasted Steps. The Act 1 table above lists each one with a map deep link.

▸Which mask shards are missable?

Shards 12 and 13 in Bilewater are easy to route past and worth marking on the map, and shard 16 sits along The Slab escape gauntlet — reachable during or shortly after the escape, so grab it while you are there. Nothing else is locked behind a one-time event.

▸Do I need mask shards to beat Silksong?

No — mask shards are optional upgrades and every ending is reachable without them. Extra masks simply make the Act 2 and Act 3 boss runbacks far more forgiving, and 100% saves want all twenty.

▸Can I collect mask shards out of order?

Yes. The act grouping is a recommended route, not a requirement — a shard becomes collectible the moment its region opens, so you can double back for any of them except the ones flagged missable above.
