Upgrading your overall health in Hollow Knight is crucial for surviving the dangerous depths of Hallownest. Every four Mask Shards you gather combine to form a full health mask, giving the Knight an extra hit point against tough enemies and bosses. Understanding where to find every shard allows you to systematically strengthen your character throughout your adventure.
Purchasing Mask Shards in Dirtmouth
The shopkeeper Sly in Dirtmouth offers four total Mask Shards for purchase as you progress. Initially, he sells two shards for 150 and 500 Geo. To unlock the remaining two shards, you must retrieve the Shopkeeper's Key from Crystal Peak and hand it to him.
Another shard in Dirtmouth can be found inside Bretta's house. You must first rescue her from a hazardous, spike-filled cavern in the Fungal Wastes using mobility abilities. Once saved, she returns to Dirtmouth and opens her home to reward you.
Earning Shards Through Combat and Bosses
Defeating formidable foes across Hallownest yields several valuable health upgrades. In the western area of the Forgotten Crossroads, defeating the Brooding Mawlek grants a shard right after the battle. You will need solid combat skills or navigation abilities like the Mantis Claw to reach this encounter early on.
Another boss-related shard requires venturing into Crystal Peak. After defeating the initial Crystal Guardian, you can double-jump into the chamber above to defeat the Enraged Guardian for your reward. Additionally, players looking for guides and community tips can visit for comprehensive strategies.
Exploring Hidden Secrets and Quest Rewards
Many shards are hidden behind tricky environmental hazards or locked behind NPC side quests. For instance, saving 5 Grubs causes the Grubfather in the Forgotten Crossroads to toss a shard down to you. Collecting 1,500 Essence for the Seer in the Resting Grounds yields another shard for your efforts.
You can also complete the intense Delicate Flower quest given by the Grey Mourner to earn a shard. Other shards are tucked away in areas like the Stone Sanctuary in Greenpath, Queen's Station, deep within the Royal Waterways, and behind a breakable wall in The Hive. Gathering every single piece ensures your Knight reaches maximum survivability.
