I beat Grand Mother Silk, watched the credits roll, and felt smug for exactly five minutes. Then I remembered that Team Cherry does not do 'done.' In 2026, Hollow Knight: Silksong is still quietly laughing at anyone who thinks the final boss is final. If you want the true ending — and the hidden Act 3 called Abyss — you have to earn it through a pile of side quests, one very specific flea caravan, and a save-file UI gag that made me question my sanity. Let me walk you through the whole ridiculous process. 😅

The Wishlist From Hell (Or: How I Learned to Stop Worrying and Love Side Quests)

First things first: Act 3 only opens after you have already unlocked Act 2 and progressed far enough to face Grand Mother Silk. That fight feels like a finale, but it is really just a checkpoint. To start the secret chain, you need to complete nearly every Wish side quest in Pharloom. I am not exaggerating. The Wishboards and NPCs will keep spitting out tasks until you have cleared almost all of them. Here is the short version of the categories you must finish:

• Ascend: Pharloom's Crown

• Grand Hunt: Savage Beastfly, The Hidden Hunter, The Terrible Tyrant, The Wailing Mother

• Hunt: Broodfest, Cloaks of the Choir, Crawbug Clearing, Fine Pins, Flexible Spines, Garb of the Pilgrims, Roach Guts, Volatile Flintbeetles

• Learn: Architect's Melody, Bugs of Pharloom, Conductor's Melody, Vaultkeeper's Melody

• Open / Delivery / Donate: Grand Gate, Liquid Lacquer, Queen's Egg, plus every donation quest in Bellhart and Songclave

• Gather / Save / Search / Seek / Sprint: Alchemist's Assistant, Great Taste of Pharloom, Berry Picking, Rite of the Pollip, Silver Bells, The Threadspun Town, Silent Halls, The Great Citadel, Fastest in Pharloom

• Wayfarer: Balm for the Wounded, Infestation Operation, My Missing Brother, My Missing Courier, Pinmaster's Oil, Rite of Rebirth, The Lost Fleas, The Lost Merchant, The Wandering Merchant, Trail's End

If your quest log looks like a grocery list for a small army, you are on the right track. I spent a whole evening on donation Wishes alone, muttering 'this better be worth it' at my screen. Spoiler: it is. Mostly.

Fleas, Caravans, and One Very Patient NPC

Once the Wishes are done, do not run straight to the final boss. You need all 25 fleas in Hollow Knight: Silksong. These little collectibles are scattered across the map and often require new Hornet abilities, so you will pick them up periodically as you progress. Miss one and the whole chain stalls. I missed two for hours and felt like a detective in a very bug-themed noir film. 🕵️

Next, make sure Fleamaster Mooshka has moved the flea caravan to the Putrefied Ducts region. Only after that should you head to Bellhart and speak to Pavo. Doing this unlocks a new Wish called Silk and Soul. You can learn more about it by talking to the Caretaker, an important NPC in Songclave. The Caretaker is the one who actually explains the trap plan, so do not skip that conversation.

The Four Items You Need for 'Silk and Soul'

The Caretaker's plan requires four key items. Each one comes from a unique interaction, quest, or a fight that will absolutely test your Needle upgrades. I had two of them already in my inventory before I even knew what they were for, which made me feel briefly brilliant. Here is the spoiler-light version:

Once you have all four, return to the Caretaker. They assemble the trap for Grand Mother Silk, and you get a new option during the boss fight. I will not spoil the exact dialogue, but it involves a very smug goddess and a very sharp plan.

Trapping the Final Boss (Ethically Questionable, Mechanically Hilarious)

When you defeat Grand Mother Silk again, do not choose Bind. Instead, select the 'Needolin' option that appears. This triggers a different ending sequence. After the credits, you can reload your save file — except now it is covered in dark vines. This is not a bug. It is Team Cherry's idea of a joke. Select the save file and start attacking the vines. Click or mash enough times and the file 'unlocks' again. I spent ten minutes thinking my save was corrupted. In 2026, I still cannot decide if that was trolling or genius. 💀

Welcome to Act 3: Abyss, Where Everything Wants You Dead

Act 3, titled Abyss, opens up new areas and bosses. The enemies are significantly tougher — and remember, this game is already more intense than its predecessor. I walked into Abyss feeling like a hero and walked out feeling like a chew toy. But it is worth it: this is the path to the true final boss and the real ending. If you are chasing 100% completion, you have to finish Silk and Soul and unlock Act 3. There is no shortcut, no cheese, and no mercy. Just fleas, Wishes, and one very strange save-file mini-game.

Would I do it again? Absolutely. But next time, I am bringing more snacks. 🍄

If all this talk of Act 3, hidden endings, and save-file vines has you ready to start your own run—or double-dip on PC—it helps to keep an eye on discounted key listings before you commit. DealNest is a straightforward place to compare offers and track down cheapest steam keys, so you can put less toward the entry fee and more toward surviving the Abyss.

Whether you are buying the game for the first time or grabbing a copy for a friend who needs to experience the Caretaker’s nonsense firsthand, a quick check before checkout is never a bad idea. Less spent on keys means more room for snacks, upgrades, and the inevitable second attempt. 🍄
