Finding yourself a bit too fragile against the bosses of Pharloom? Boosting Hornet’s health is one of the best ways to gain an edge, and that means hunting down rare Coghearts (Cogheart Silksong).
Functioning just like Mask Shards from Hollow Knight, these collectible fragments are Silksong’s core health upgrade mechanic. Once you collect three, you can forge them into a permanent health core, giving you the resilience needed to survive dangerous exploration and tough encounters.
Cogheart Silksong: Where to Find Your First Cogheart in Moss Grotto
Your first Cogheart piece is waiting in Moss Grotto, and you can grab it as soon as you reach the area. This one doesn’t require any special abilities, making it the perfect starting point. From the first bell (checkpoint) in Moss Grotto, the path is straightforward.
- Head right from the checkpoint until you enter the large, open cavern with cascading acid waterfalls.
- Instead of dropping down, platform up towards the top-left corner of the room. You’ll spot a section of wall covered in leafy vines.
- Jump into the vines—it’s a fake wall! The Cogheart is on a small pedestal just through this hidden passage.
How to Get the Cogheart in the Deep Docks (Silk Spear Required)
Your next stop is the Deep Docks, a sprawling mechanical zone you can access after your triumph in the Lace Temple. Getting this second Cogheart requires the Silk Spear ability. You’ll find it sitting on a high, inaccessible platform across a wide chasm.
This puzzle introduces the Silk Spear’s utility beyond combat. From the edge of the chasm, look across to spot a rusted lever on the far side. Aim your Silk Spear and throw it to latch onto the lever, then pull it. This activates the dock’s machinery, lowering the platform with the Cogheart down to you. Hop over and grab your prize.
Finding the Final Cogheart: The Gilded City’s Hidden Secret
The final Cogheart is cleverly hidden within the opulent Gilded City. As you explore its golden halls, keep an eye out for a massive, silent bell in the upper districts. The wall directly next to this bell has faint, telltale cracks that distinguish it from the pristine masonry around it—a classic secret, hiding in plain sight.
A single attack will shatter the facade, revealing a short, safe passage. There are no enemies or tricky platforming puzzles waiting for you here, just your well-earned prize at the end. Grab the last Cogheart to complete your set.
Cogheart Silksong: You Have 3 Coghearts—Here’s Where to Go to Upgrade Your Health
With all three Coghearts in hand, head to the main hub city, Bonebottom, to claim your reward. Find the Cogsmith’s shop—look for the prominent gear-and-hammer sign. He will forge your fragments into a new health core, giving Hornet a permanent survival boost. This upgrade provides the confidence to explore further and the resilience to win your next fight.
