I’ve sunk more hours into Hallownest than I’d care to admit—seriously, it’s a bit bananas. What keeps dragging me back isn’t just the razor-sharp combat or the moody, hand-drawn visuals; it’s the off-the-beaten-path stuff that truly sets Hollow Knight apart. You know the drill: you’re minding your own business, and then some cryptic NPC drops a hook that spirals into a full-blown obsession. Whether you’re hunting for a shred of extra lore or just chasing bragging rights, the side quests in this game hit different—they’re the secret sauce that turns a great Metroidvania into a modern classic. So grab your Dream Nail and a stiff cup of courage, because I’m breaking down the most unforgettable detours I’ve ever taken down the kingdom’s rabbit holes.
The Grubfather’s Lament
I’ll be real with you: my first reaction to finding a trapped grub was pure “aww.” Those chubby little caterpillars crying in glass jars scattered all over the map? I freed them without a second thought, grinning every time they burrowed back to their dad. The setup feels cozy—like reuniting a family. Then you collect all 46 grubs, and the payoff sucker-punches you. The Grubfather, all bloated and content, has gobbled them up. Wait, what? I sat there slack-jawed. Is it some bizarre metamorphosis, or a cannibal buffet? The community has been chewing on that question since day one. Gameplay-wise, scouring every nook for these guys is a completionist’s dream, and the reward—the Grubberfly’s Elegy charm—is a sweet cherry on top. But honestly, the real prize is the memory of that jaw-dropping moment when innocence curdles into something deeply unsettling. Classic Hollow Knight.
The Great Nailsage’s Arts
Early on, Sly seems like your run-of-the-mill merchant—small, chatty, a bit grumpy. I rescued him from the clutches of a Husk and thought that was that. But oh boy, was I wrong. After I’d tracked down the three Nailmasters scattered across Hallownest and soaked up their flashy techniques, a thought nagged at me: why does Sly mutter about “those three” when you hit him with the Dream Nail? Curiosity piqued, I trotted back to his shop. Talk about a mic-drop moment. The unassuming bug reveals himself as the Great Nailsage, the very master who taught all three arts. The Nailmaster’s Glory charm he hands over makes charging Nail Arts a breeze, but the real kicker is the feeling of piecing together a puzzle you didn’t even know existed. It’s one of those “aha!” beats that rewards players who snoop around, and it cemented Sly as a certified legend in my book.
The Nailsmith’s Dream
Upgrading your Nail is a no-brainer—bigger damage numbers, yes please. The Nailsmith in the City of Tears is your guy, hammering away with Pale Ore until your blade is a thing of beauty. When I finally maxed out the Pure Nail, I was riding high. Then the poor fellow looks at his masterpiece and begs you to end him with it. Talk about a gut punch. The game doesn’t shove a moral lesson in your face; it presents a quiet choice. I sheathed my Nail and walked away, because something about his devotion felt more tragic than triumphant. Later, I stumbled upon him vacationing alongside Nailmaster Sheo, brush in hand, finally at peace. A happy ending for a side character in Hollow Knight? It almost feels illegal. This quest is a masterclass in subtle storytelling—no fanfare, just a small, beautiful conclusion that rewards restraint. It still warms my cynical little heart.
Colosseum of Fools
Let’s not mince words: the Colosseum of Fools is a whole vibe. Nestled in the corpse of a titanic bug, this gladiatorial pit throws wave after wave of enemies at you while a crowd of lunatics howls for blood. I strutted in feeling like hot stuff after beating most of the story bosses, only to get my shell handed to me on a silver platter during the Trial of the Fool. Three escalating trials offer riches like a Charm Notch, Pale Ore, and a mountain of Geo, but the true reward is the sheer adrenaline rush. You haven’t lived until you’re bouncing between Primal Aspids and Mantis Traitors with no floor to stand on, praying your Monarch Wings don’t fail you. It’s entirely optional, which makes clearing it feel like a personal badge of honor. If you’re after a white-knuckle challenge that’ll test every ounce of your combat finesse, the Colosseum is where legends are forged—or broken.
The Grimm Troupe
When the Grimm Troupe rolled into town with their crimson tent and eerie accordion music, I knew chaos was about to unleash. This free DLC questline is a deliciously twisted rabbit hole. You dash across the map collecting nightmares, fighting quirky Grimmkin, and making a pivotal choice: finish the Ritual or banish the Troupe for good. Both paths lead to a unique charm, but if you’re a glutton for punishment like me, you’ll face Nightmare King Grimm—arguably one of the most sublime boss fights in the entire game. His attack patterns are a fiery ballet of pain that demands perfection, and beating him felt like summiting a personal Everest. The lore drip-feeds hints about higher beings and cycles of decay, adding layers to an already rich world. Even now, players swap war stories about this quest, and it remains a gold standard for how to expand a game with free content.
The Path of Pain
The name isn’t just for show—this hidden gauntlet in the White Palace is a nerve-shredding trial of precision platforming. No bosses, no treasure, just you, a million buzzsaws, and thorns that laugh at your misfortune. I lost count of how many hours I spent hurling myself at those spiky corridors. My thumbs ached, my sanity frayed, and I questioned every life choice that led me there. But when I finally hit that last lever and watched the tiny lore cutscene unfold, I was practically vibrating with euphoria. The Path of Pain gives zero tangible rewards—no charm, no notch, not even a lousy Geo. It’s a pure test of grit, and clearing it is the ultimate mic-drop for any Hollow Knight veteran. In 2026, speedrunners still duel over this fiendish course, and casual players whisper its name with a mix of dread and reverence. If you want to see what you’re really made of, take the plunge. Just don’t say I didn’t warn you.
Looking back, these side quests are what transformed my hundred-hour journey from a simple playthrough into a deeply personal saga. They’re not checklists; they’re stories, challenges, and emotional rollercoasters that stick with you long after the credits. Team Cherry crafted a world where every detour might hide heartbreak, triumph, or both. So next time you boot up the game, skip the beaten path—you never know what gem you’ll unearth.
