Honestly, if you've been refreshing Team Cherry’s Twitter page for the last five years, you’re probably vibrating at a frequency that could shatter glass. We’ve all seen the footage. We’ve parsed the 2019 E3 demo until our eyes bled. But one specific mechanic consistently flies under the radar compared to Hornet's gymnastics: the Silksong Old Hearts.
It’s easy to miss. At a glance, it looks like the standard health bar from Hollow Knight. But it isn’t. Not even close.
In the original game, the Knight’s life force was tied to SOUL. You hit things, you get white goo, you hold a button to focus, and a mask pops back. Simple. Brilliant. It defined the pace of the game. Silksong throws that out the window for something much more aggressive. It’s faster. It’s scarier. It basically forces you to play like a caffeinated wasp.
What are Silksong Old Hearts and how do they actually work?
Let’s get the basics down. In the Pharloom demos, Hornet’s health is represented by these intricate, cocoon-like containers. Unlike the Knight, Hornet doesn’t sit there and meditate to heal one mask at a time. She uses Silk.
When your Silk meter is full, you can trigger a "Bind."
This is where the Silksong Old Hearts come into play. Instead of the slow, methodical ticking of masks returning, Hornet heals almost instantly. She wraps herself in silk and—bam—multiple hearts are restored in a fraction of a second.
But there’s a catch. There is always a catch with Team Cherry.
If you get hit while trying to Bind? You lose the Silk. You don’t get the health. You’re left standing there looking like a fool while a clockwork soldier hammers you into the dirt. It turns healing from a "find a safe corner" mechanic into a "find a half-second window in the middle of a combo" mechanic. It’s high-stakes. It’s sweaty. It’s exactly what the sequel needed.

The mechanical shift from masks to silk-bound hearts
You’ve gotta realize that the Knight was a void-filled vessel. It was slow. Sturdy, sure, but slow. Hornet is a princess-protector. She’s agile. The Silksong Old Hearts system reflects that agility.
Think about the boss fight against Lace. In that fight, there’s no room to breathe. If you try to use the old Hollow Knight logic of running to the far side of the arena to heal, Lace will close that gap before you’ve even started the animation.
- Healing is faster, but the windows are tighter.
- Silk is generated by hitting enemies, just like SOUL, but you use it for everything.
- Your tools, your heals, your special attacks—they all pull from the same pool.
This creates a massive "resource tension." Do I use my Silk to throw a sting shard and end this fight now, or do I save it because I’m down to my last few Silksong Old Hearts? Most people are going to panic and choose wrong. That's the beauty of it.
A different kind of punishment
In Hollow Knight, if you had one mask left, you were one mistake away from the bench. In Silksong, having one heart left feels even more desperate because Hornet’s movement is so much more fluid. You feel like you should be able to escape, but the game is designed to punish that overconfidence.
The "Old Hearts" terminology itself hints at a deeper lore connection. We know Pharloom is a kingdom of Silk and Song. Are these hearts biological? Are they mechanical? We’ve seen the "Bell Beast" and other clockwork-heavy designs. It’s possible that the way Hornet sustains herself is fundamentally different from how the Knight did it because she isn't a creature of the Void. She’s alive. She’s biological.
Why the community keeps obsessing over the UI
Check any Reddit thread about the demo UI. People are obsessed with the filigree around the health bar. The Silksong Old Hearts look like they’re encased in silver or white metal.
Some theorists, like the folks over at Mossbag’s community, have pointed out that the shards we see might be "Rosaries." This is a new currency, but it also ties into the aesthetic of the hearts. In the Deep Docks area, we saw Hornet interact with shrines that seem to reinforce her "shell."

If you look at the 2022 Xbox trailer—the one that launched a thousand "is it out yet?" memes—the hearts have a distinct "crack" when damaged. It’s a much more visceral sound than the mask-shattering sound of the first game. It sounds like ceramic breaking.
The "Grey" Heart Mystery
There’s also the footage of what looks like "depleted" or "grey" hearts. In the original, a mask was either there or it wasn't (unless you had Lifeblood). In Pharloom, there appears to be a state where a heart is "broken" but perhaps not entirely gone.
Wait. Let’s backtrack.
Actually, the most interesting theory is that Hornet can "over-silk" her hearts. We've seen gameplay where the UI glows with a golden hue. Is this a temporary buff? Is it tied to the "Song" side of the game’s title? We know very little about the Song mechanics compared to the Silk mechanics. But if the Silksong Old Hearts can be buffed by music, we’re looking at a combat system with more layers than an onion.
How to prepare for the Silksong health system
If you think you're going to walk into Silksong and play it like Hollow Knight, you're going to get bodied. Seriously.
The Silksong Old Hearts system requires a total rewire of your muscle memory. You have to get used to "The Burst." In the first game, you’d chip away, retreat, heal. In this one, you have to stay in the pocket. You have to be aggressive to get your Silk back, and you have to use that Silk to heal instantly while Hornet is mid-air or mid-dash.
- Stop "Panic Healing." In Silksong, a panic heal is a death sentence. The Bind animation is fast, but it’s loud.
- Learn the Silk economy. Your "Old Hearts" stay full only if you’re landing hits. If you miss your grapples, you’re starving yourself of health.
- Watch the background. Pharloom is vertical. Falling doesn't just reset you; it puts you in a position where healing your Silksong Old Hearts is nearly impossible because of the environmental hazards.
The Lore of the "Old" in Old Hearts
Why call them "Old Hearts"?

Team Cherry doesn't name things by accident. If the health containers are "Old," it implies there’s a "New" way, or perhaps these are relics of the Weaver tribe that Hornet is reclaiming. Remember, Hornet is the daughter of Herrah the Beast. Her connection to the Weavers is her birthright.
The Silksong Old Hearts might literally be ancient Weaver technology. While the rest of Pharloom has moved toward clockwork and brass, Hornet is using the old ways—the organic, silk-based vitality of her ancestors. It’s a clash of civilizations happening right inside your health bar.
It’s also worth noting the color palette. Everything in Hollow Knight was blue and black (Void and Lifeblood). Everything in Silksong is red, gold, and white. Red silk, gold songs, white hearts. It feels warmer, but in a way that’s almost feverish.
Actionable steps for the Pharloom-bound
Since we're all playing the waiting game, the best thing you can do is refine your "aggressive" playstyle in the original game.
Go back to Hollow Knight. Put on the Quick Focus and Steady Body charms. Force yourself to play against bosses like Nightmare King Grimm without ever moving to the corners of the map. If you can learn to heal while standing right under a boss's nose, you’ll be ready for the Silksong Old Hearts transition.
Keep an eye on the official Team Cherry blog for any mention of "Crest" updates. We know Hornet can swap Crests to change her abilities. It’s highly likely that certain Crests will modify how your hearts behave—maybe giving you more health at the cost of slower Silk generation, or vice versa.
The wait for Silksong has been long, but these mechanical shifts prove it's not just a map pack. It's a fundamental reimagining of what a 2D action game can be. Master the Silk, protect your hearts, and get ready to climb to the Citadel.
