It’s 2026, and I can still feel the phantom ache in my fingers from the hours I poured into Hollow Knight: Silksong. When it finally released last year, I dove into Pharloom’s depths knowing full well that Team Cherry would raise the bar. What I didn’t expect was just how brutally they’d redefine boss difficulty. Every duel left a scar on my muscle memory, but ten encounters stand out as the absolute peak of pain and brilliance. This is my personal ranking of the hardest boss fights in Silksong, told from the trenches.

10. Shrine Guardian Seth – A Tribute That Fights Back

I remember walking into Seth’s shrine thinking, “This is a tribute boss, how tough can it be?” The answer came in the form of a shield flying at my face faster than Hornet’s own needle. Seth had clearly been watching too much Captain America – the guy hurls his shield, teleports to it, and then immediately chains into a ground slam or aerial scythe sweep. His speed felt unreal for a mid-game boss, and I died more times than I care to admit simply because I couldn’t predict where he’d reappear.

What kept him from breaking me entirely was his lack of extra phases. Once I learned to watch for the shield’s white flash before a teleport, I could eventually turn the fight into a rhythm. Still, Seth taught me that sentimentality doesn’t mean mercy in Pharloom.

9. Moorwing – The First Mountain You Can’t Climb

Early Silksong lulled me into a false confidence. I steamrolled most bosses on my first try. Then I met Moorwing, and suddenly I was a trembling novice again. The first thing you notice is the damage – almost every attack rips off two masks of health, which forces you to respect every move. The second thing is that massive feathered body. It dominates the screen, and unless you’re a pogo prodigy, you’ll keep bumping into it like an idiot.

Moorwing’s projectile phase is where the real torture begins. It spews out bursts of homing feathers in patterns that look predictable but somehow always nick you when you’re healing. That fight was my wake-up call. I stopped trying to brute-force my way through and started actually learning. Without that humbling, I would have never survived what came next.

8. Widow – Triple Threat From Bellhart

If Moorwing was a wall, Widow was the entire fortress. I stumbled into her Bellhart lair with barely any healing items and immediately wished I hadn’t. She’s a whirlwind of diagonal dashes that cross the whole arena, bouncing bells that ricochet off walls at impossible angles, and ground spikes that erupt just when you think you’re safe. There’s no loophole to exploit – Widow is simply faster, stronger, and more durable than you.

Phase two adds insult to injury by combining all of that into overlapping attacks. I vividly recall screaming at my screen as three bells, a dash, and a spike field all triggered within a second. The only way through was sheer concentration and a willingness to accept that I’d be stuck there for a very long time.

7. Groal the Great – Frustration Incarnate

Let me be blunt: I despise the Bilewater area, and Groal is its rotten cherry on top. The fight itself is less a duel and more a gauntlet of environmental torture. There are maggots squirming in toxic puddles, random enemy projectiles flying from off-screen, and Groal himself – a swollen monstrosity that moves way too fast for its size and hurls bouncing bombs into the chaos.

This boss didn’t test my skill; it tested my patience. Every death felt cheap because half the time I wasn’t even hit by Groal directly – I’d just get clipped by a stray maggot or a delayed explosion while trying to dodge the boss’s own attacks. Groal lands here because, although he’s technically beatable with persistence, the whole experience left me more bitter than any other fight.

6. Cogwork Dancers – Elegant Geometry of Pain

Here’s the mind-bend: the Cogwork Dancers telegraph every single attack with glowing lines, yet I still died more to them than I did to some endgame threats. The duo is a masterclass in positioning. You can see exactly where the blade is about to swing, but the arena becomes a puzzle of overlapping red zones. One dancer pins you while the other forces you to move, and suddenly you’re trapped in a corner with no safe spot.

What I loved (and hated) was that traditional boss-cheese tactics didn’t work. Pogoing could land you right into a second blade; memorizing patterns wasn’t enough because the combinations changed based on your position. It forced me to unlearn bad habits and trust my spacing more than my reflexes. By the time I won, I felt like a chess grandmaster.

5. Savage Beastfly – Annoyance With Wings

There were only two moments in Silksong where I genuinely slammed my controller: navigating Bilewater and fighting Savage Beastfly. This creature looks like it escaped from the original Hollow Knight with its basic charge-and-summon pattern, but Team Cherry cranked the annoyance dial to eleven. Double damage on contact meant I couldn’t afford a single misstep, and the tiny arena filled with summoning minions forced me into constant, exhausting movement.

The second encounter made everything worse by breaking the floor and dropping me into an even tighter space without the advanced movement tools I’d later unlock. I felt sluggish and overwhelmed, and winning often came down to luck rather than skill. It’s a fight that feels unfair in the worst way, and I never want to repeat it.

4. Second Sentinel – The Purest Duel

After so many gimmick-heavy encounters, the Second Sentinel felt like a breath of fresh air – sharp, bitter, and impossibly demanding. This automaton guards its arena behind a lengthy unlock sequence, and once you finally step inside, there’s nothing but you, your needle, and a relentless mirror image. It combines Seth’s speed, Widow’s multi-directional attacks, and the Cogwork Dancers’ telegraphed precision into a small, unforgiving ring.

No minions, no stage hazards; just pure pattern recognition and flawless execution. Every time I died, I knew it was my fault. Slowly, I learned when to dash through its combos, when to pogo for silk, and when to retreat. The victory felt earned in a way few other bosses managed, and I’d happily fight it again just for the thrill.

3. Last Judge – Where Pilgrims Go to Die

It’s no surprise that the Last Judge guards the gate to Act 2, because she is the ultimate skill check of the early campaign. Her speed doesn’t match some others on this list, but her damage output is catastrophic. Pillars of fire erupt from the ground after her charges, and when she spins her weapon, rings of explosion expand outward like a death blossom.

Phase two turned my confidence to ash. She leaps frantically, trailing fire from every attack, and I never knew whether to hug her to avoid the flames or back off and risk being juggled. Micro-decisions became life-or-death. The Citadel has been empty for centuries, and after facing the Last Judge, I understood why. Only players who’ve mastered positioning and pogo dodging can hope to pass.

2. Lost Lace – The Void’s Unforgiving Embrace

I had mixed feelings knowing I’d face Lace a third time, but all doubts vanished when her void form appeared. Her signature rapier dance was already lethal, but now she wields dark tendrils that lash from the ground and sky, often stealing health right as I dodged her combos. With each new phase, she becomes faster, more aggressive, and absolutely monstrous.

Teleports, screen-filling waves of pure darkness, lightning projectiles, and homing orbs – Lost Lace throws everything at you, and she never stops. I spent hours in The Abyss, dying over and over, but the moment I finally landed that last needle strike, I felt a rush I hadn’t experienced since beating Nightmare King Grimm. Lost Lace is the final boss Silksong deserved, and she almost broke me.

1. Skarrsinger Karmelita – The Queen of Perfection

And then there was the queen. Skarrsinger Karmelita isn’t just the hardest boss in Silksong; she’s arguably the most beautifully animated threat I’ve ever faced. Every movement is a liquid dance of deadly grace, and from the first second I knew I was in trouble. She blends the relentless speed of Pure Vessel with the mechanical depth of Nightmare King Grimm, and she demands total mastery of every system the game has taught you.

Before each attempt, I had to clear a wave of her lesser children, but honestly that became a meditative ritual – they fed me silk and focus. The real fight was a symphony of pain. Her sweeping staff combinations, aerial dives that leave trails of fire, and that heart-stopping grab attack where she drains your life: all of it requires near-perfect play. I died more to Karmelita than to every other boss combined.

But she never felt unfair. Every failure was a lesson, and after hundreds of attempts, my fingers moved on instinct. When I finally felled her, I stood in silence, hands shaking, knowing I’d just overcome the very peak of Pharloom’s challenge. Skarrsinger Karmelita is a masterpiece of difficulty – a final exam that only the dedicated can pass, and I wear that victory like a badge of honor.

Reflecting on these intense battles, it becomes clear that the journey through Silksong is not just about defeating foes, but about embracing the challenge and evolving as a player.
