Update your settings

I'll be honest with you — after sinking 40 hours into Hollow Knight: Silksong back in 2025, I completely forgot about Silk Hearts. My inventory just sat there with that first little golden orb, and I barely paid it any attention. Big mistake. These things are absolute lifesavers once you realize they're the reason you can scrape together enough silk for a Harpoon throw in the middle of a boss fight. If you're running around Pharloom in 2026 and wondering why your silk pool feels perpetually dry, stick with me. I've been through every nook and cranny to track down all three Silk Hearts — and the cheeky pseudo-fourth one that the game tries to hide from you.

Silk Hearts are more than just collectibles; they're your passive silk regeneration. One heart equals one puddle of silk that slowly refills over time, letting you use skills like Needle Strike or Thread Storm without panicking about resources. You get two just by playing the main story, but that third heart? It's locked behind a secret boss that still gives me chills when I think about it. Let me walk you through each one, from the chillest pickup to the sweatiest challenge.

Silk Heart #1 – A Gentle Introduction

Right around the time I first hit the Marrow, I stumbled into the Bell Beast's arena with nothing but a Silkspear and a prayer. The fight itself feels like a dance — mostly because she telegraphs her attacks with those haunting chimes. Once her health bar melted away, a tiny golden orb floated up from the ground, and Hornet got yanked into that dreamy platforming sequence we all know.

Honestly, I didn't appreciate this heart until much later. The Bell Beast is a story-gated fight — you literally can't miss her if you follow the main path through Mosshome and the Marrow. Complete the memory platforming, grab the Silk Heart, and boom: you now regenerate one silk passively. At that point, I just shrugged and thought, "Cool, now I can use the Harpoon without feeling poor." It's only when you start stacking hearts that the magic really hits.

Silk Heart #2 – Lace's Tougher Sister

Oh, Lace. If you thought your first encounter with her in the Deep Docks was stressful, wait until you face her again in the Cradle. This rematch comes right after you collect the three Melodies and slide into that old lift near the Cogwork Dancers' arena. I walked in with three nail upgrades and still had my hands sweating.

She deflects everything. I mean, everything. The trick is to bait her lunges and punish the recovery frames, but man, her rhythm is way more aggressive here than in the Docks. Still, after a few tries (okay, more than a few), she goes down, and that familiar floating orb appears. Just like before, you chase it through a short silk-memory section and earn your second Silk Heart. Now you have two pips of passive silk — and suddenly you can spam tools more freely. It's a genuine turning point in how the game feels.

Silk Heart #3 – The Surgeon's Key Secret

Here's where things get spicy. I cleared Whiteward early on and completely missed the hidden path that leads to the Surgeon's Key. Turns out you need to go to that long horizontal room with the three Morticians — those scissor-wielding creeps that charge on sight — and instead of continuing left, you jump up into a shaft of light above the rightmost section. I felt like an idiot when I finally found it.

Climb up, smash through some debris on the far left, and use your Clawline Harpoon to yank a hanging ring. A corpse drops down clutching the Surgeon's Key. That key leads to a circular slot in the southwest corridor of Whiteward, left of the main elevator. Insert it, drop into the hole, and you're thrust into one of the most underrated boss fights in the whole game.

The Unravelled – Phase 1

The arena starts quiet. A couple of regular enemies spawn — they're not tough, but they have patterns you'll need to recognize because they'll come back later. Once you clear them, the real nightmare crawls in.

The Unravelled lumbers out with just two attacks at first: a corpse shot and a swooping lunge. Easy enough, right? I thought so too. Then the fight shifts, and he decides to summon extra enemies — these floating spinny things that home in on you like angry bees. I found that juggling them from below worked best; jump over them, hit their backs, and keep moving.

Phase 2 and Beyond

After the first phase change, the arena gets littered with silk plumes that shoot spears upward. They hang in the air for a moment before crashing down. While you're dodging that, The Unravelled upgrades his corpse shot to spit out three bodies instead of two. On my first attempt, I panicked and ate every single spear.

The third stage is basically more of the same chaos. Kill the extra spawns, chip away at the boss while dodging spears, and don't chase damage when the screen fills up. It's a grind, but eventually he crumbles. The memory platforming that follows is mercifully short, and at the end you get your third Silk Heart. Now your passive regeneration has tripled — honestly, it feels like cheating.

Bonus: The Weavelight Faux-Heart

If you want to push your silk pool even further, there's a blue tool called the Weavelight. It doesn't actually count as a Silk Heart, but it gives you a fourth pip of silk and speeds up the regeneration rate. To snag it, head to Weavenest Atla and tackle the Dual Moss Mothers on the far left of the mossy area. The fight is two Moss Mothers at once, which sounds terrifying, but they share a health pool and are way slower than the original.

With the Weavelight active, you effectively have a fourth heart — and the faster regeneration means you can pull off needle techniques even when dodging constantly. It's not required for 100%, but if you're planning to tackle the hardest bosses in the game (looking at you, Nyleth), this thing is a gift.

I've now got all three Silk Hearts and the Weavelight equipped, and my Hornet feels nearly invincible in the silk department. If you're stuck on any of these, drop me a comment (metaphorically) and I'll help you out. 2026 might be filled with new releases, but Silksong still has a grip on my soul — and it probably always will.

As you continue to unravel the mysteries of Silksong, it’s worth noting that finding gear upgrades like the Weavelight can sometimes feel like a treasure hunt.
