Mask Shards are Items in Hollow Knight that are used to increase the Knight's health.


Mask Shards are parts of Ancient Masks. 4 Mask Shards are needed to complete an Ancient Mask, which increases the Knight's health by one.

With a total of 16 Mask Shards in the game, the Knight can increase their Mask count by 4, for a maximum of 9, not counting bonuses from Charms and Lifeblood Cocoons.

How to Acquire

There are a total of 16 Masks Shards to be found in the game:

2. Bought from Sly in Dirtmouth for Geo.png 500
  • Shop description:
I found another of these. If you look closely, there's some nice engraving work on them.

3. Bought from Sly in Dirtmouth for Geo.png 800
  • Shop description:
You're collecting these, aren't you? Well you're in luck, I found another in my storeroom.
This is the last one though, so it's priced accordingly.

4. Bought from Sly in Dirtmouth for Geo.png 1500
  • Shop description:
As it turns out, I do actually have one more of these shards left. Very last one!
I feel bad charging you so much for the previous shards, especially because it means I have to charge even more for this one.

  • The A Weird and Wonderful World trailer shows that an early name for the Mask Shard was "Grey Mask Shard".[1] In the Ferocious Foes trailer, it was called a "Shell Fragment".[2]
  • The music heard after acquiring four Mask Shards originates from a short sample track that was posted when Christopher Larkin was hired as the game's composer.[3]
  • If the Knight has extra Lifeblood Masks when the number of Masks is increased, the Mask gained overlaps a Lifeblood Mask, creating a white Mask that drips and has a blue background like a Lifeblood Mask. However, both Masks remain and taking damage removes the Lifeblood Mask first.
  • Having the Joni's Blessing Charm equipped when the number of Masks is increased has no effect on the Knight's current health. It is only updated when resting at a Bench.
