Hollow Knight Mask Shards: Locations and Sly's Prices

Game files, build 1.5.78.118334 min read

The game files hold 11 Mask Shard pickups. 7 sit in rooms our map draws, so they have pins; 4 are in rooms the pause map has no place for. Four shards make one mask, and Sly's price sheet adds 4 shard prices on top.

Most Hollow Knight guides give you a list of places and leave it there. This one is a checklist you can tick as you go, built from the scene files: every room that holds a Mask Shard, how you get into it, and the closest bench for the walk back. The tick boxes stay in your browser.

How many shards you need

A new save starts with 5 masks and the game's cap is 9, so there are 4 masks to earn. The item text gives the exchange rate: the first shard reads "Collect three more", the stage before the last reads "Collect one more", and the finished piece is the Ancient Mask. That is 4 shards per mask, 16 for all four.

Two achievements track it. Protected asks you to "Acquire 4 Mask Shards", and Masked asks you to "Acquire all Mask Shards".

Where my count stops

11 pickups plus Sly's 4 prices make 15 sources on paper, one fewer than the 16 shards four masks take. Sly's stock sits in shop prefabs I did not decode, so I cannot say which of his four prices are live at once. Treat his list as the part to confirm in the game.

The 11 shards, area by area

The list follows the order of the areas hub, not a difficulty order: the files hold no difficulty. "Closest bench" is a straight line on the map, not a walking route. Every pinned shard opens on the mask shard layer.

  1. Dirtmouth: Room_BrettaNo map position

    This is Bretta's house. Its doorway on the right leads out to the Town scene, which is Dirtmouth, so you walk in from there (a second door in the room is scripted and its target is not in the room data).

  2. Forgotten Crossroads: Crossroads_09On the map

    It shares the room with the Brooding Mawlek pin. Closest bench on the map in a straight line: Crossroads_30 (Forgotten Crossroads).

  3. Forgotten Crossroads: Crossroads_13On the map

    Closest bench on the map in a straight line: Crossroads_30 (Forgotten Crossroads).

  4. Forgotten Crossroads: Crossroads_38No map position

    This is the Grub King's room: the scene holds a Grub King, a Fat Grub King and a long row of grub counters. Its only doorway in the room data leads to Crossroads_07. The same room holds a Pale Ore pickup, so one trip takes both. How many grubs the King wants is held in a script I did not read.

  5. Greenpath: Fungus1_36No map position

    A dead-end room in Greenpath: its only doorway joins the right-hand exit of Fungus1_35, so go in through that room.

  8. Crystal Peak: Mines_32On the map

    It shares the room with the Crystal Guardian pin. Closest bench on the map in a straight line: Mines_18 (Crystal Peak).

  9. Resting Grounds: Room_MansionNo map position

    This is the Grey Mourner's mansion (the room holds the NPC the files call Xun). You enter it through the door named door_Mansion in RestingGrounds_12. The game's own text says the Grey Mourner lives in the Resting Grounds.

    It sits next door to the Hive Knight room (Hive_05). Closest bench on the map in a straight line: Deepnest_East_13 (Kingdom's Edge).

Sly's price list

The game's price sheet has four Mask Shard prices for Sly: 150, 500, 800, 1,500 Geo. The shop is the Room_shop scene, and a second shop menu sits in his storeroom (Room_Sly_Storeroom). The price keys are there; the stock list that decides when each shard goes on sale is inside the shop menu prefab, which I did not decode. So I give the prices and stop there.

Sly is one of the 4 shop regions pinned on the vendor layer.

Common mistakes

  • Trusting the pins alone. 4 of the 11 pickups have no pin, because their rooms are not on the pause map.
  • Skipping the Grub King's room. It holds a Mask Shard and a Pale Ore pickup. See the Pale Ore guide.
  • Counting Sly's four prices as four extra pickups. They are shop prices, not scene objects.

About these numbers

These pages read the game files of build 1.5.78.11833 (2021). Steam now has 1.5.12620 (March 2026) with fixes and no new areas; PinDrop has not re-read that build.

Room names such as Crossroads_09 are the scene names in the files. The map and the 112% checklist use the same names.
