For players who have pushed Hornet through every corner of Pharloom and watched that 100% completion notification finally appear, it can feel like the adventure is truly over. Yet beneath the surface of Team Cherry’s sprawling sequel lies a secret layer of endgame content that does not count toward the official percentage but represents some of the most demanding and rewarding challenges Hollow Knight: Silksong has to offer. These are the Mementos — collectible trophies that hang on the wall of the Bellhome as permanent reminders of battles won, friendships tested, and skills honed to near perfection.

Since its highly anticipated release, Silksong has charmed the community with its intricate world design and fluid combat. The Memento system deepens that experience, functioning as a post-100% pursuit that encourages mastery of mechanics and a thorough exploration of every biome. Each Memento is tied to a specific feat, from defeating optional super-bosses to clearing absurdly difficult movement gauntlets. In 2026, dedicated fans continue to dissect these objectives, and having a clear roadmap is invaluable for anyone aiming to fill that wall completely.

The Boss Hearts: A Choice of One

The journey into Mementos begins with a curious set of items known as the Boss Hearts. Four variations exist — the Conjoined, Hunter’s, Pollen, and Encrusted Hearts — but Hornet can only keep one of them. The game’s core progression eventually requires gathering three hearts to descend into the Abyss and face Lost Lace. However, an optional encounter in Verdania with the Green Prince provides an extra substitute heart. By swapping one of the required hearts for the substitute, players can decide which of the four original Boss Hearts they will forgo handing over to the Shamans. The heart that remains in your inventory becomes the first Memento pinned to the Bellhome wall, making this decision surprisingly weighty. Choose the one whose boss fight resonated most, or simply the one you never want to suffer through again.

Hero’s Memento: A Bittersweet Farewell

Next up is an emotional confrontation that many players stumble upon while completing side wishes. The Hero’s Memento is awarded after defeating Garmond, a character whose fate has been twisted by the void. To initiate the encounter, visit the Wishboard in Bellhart and accept Zaza’s request. Ride a bell beast to the Blasted Steps, rest at the bench, and then head left into a vertical chamber. In the bottom left lies a long corridor where Garmond waits, corrupted and aggressive. The battle is chaotic, with Garmond’s void-touched attacks capable of shredding Hornet’s health in seconds if you get greedy. Passive tools like cogflies or tacks excel here, allowing you to maintain damage output while concentrating entirely on dodging. Stick to quick single needle strikes and back away immediately; crowding him invites devastating counterattacks. Once you have granted him release, the Hero’s Memento will be yours.

Craw Memento: The Father of All Craws

After advancing into Act 3, a mysterious change occurs: the Craw Summons item will appear beside Hornet whenever she rests at a bench. These summons serve as an invitation to revisit Craw Lake and the house that overlooks its waters. Entering the large door within transports you to an arena swarming with feathered fiend varieties. Amid the chaos, the Crawfather emerges as the main threat. While his own attack patterns are relatively straightforward, the real difficulty comes from the incessant stream of additional Craw enemies he spawns. Prioritize clearing the small fry first to avoid being overwhelmed. Persistence is rewarded with the Craw Memento and a nest attachment for the Bellhome, which passively generates shards and rosaries over time — a nice bonus for endgame resource farming.

Grey Memento: The Watcher at the Edge

Hidden deep within the Sands of Karak, the Watcher at the Edge guards the Grey Memento. To locate this optional boss, navigate to the southwest section of the area where the Memory Locket was found in the early vine-platforming rooms. With the Silk Soar ability, Hornet can reach a previously inaccessible entrance. At the far left, a silent statue waits. Playing the Needolin awakens the Watcher, initiating a duel against an opponent that moves with unsettling fluidity. The Watcher employs short-range teleports and rapid underground dashes that can close the gap instantly. Maintaining a medium distance is key — just outside the Watcher’s striking range but not so far that you cannot retaliate. Refrain from attacking more than once or twice at a time; the Watcher will block multi-hit combos and respond with a swift parry. A patient, deliberate approach will earn you the Grey Memento, proving that Act 3 skill level is no guarantee of an easy victory.

Surface Memento: A Vertical Odyssey

Unlike most Mementos, the Surface Memento requires no combat at all. Instead, it demands absolute mastery of Hornet’s movement toolkit. Begin at the summit of the ruined Cradle, where the Pale Nail silk skill is acquired. Continue upwards to discover a tiny entrance that leads to an immense vertical shaft. Using the clawline and faydown cloak to pogo off enemies and environmental hazards, players must ascend toward the mythical surface of Pharloom. The climb is relentless and punishes even minor mistakes with a long fall back down. Once you have conquered the ascent, travel as far east as possible until you reach the remnants of an ancient dwelling. Playing the Needolin here will cause the Surface Memento to drop from the roof — a testament to your platforming prowess.

Hunter’s Memento: Completing the Journal

The Hunter’s Memento demands a completionist mindset. To obtain it, you must defeat every enemy type in the game a certain number of times and fully fill out Nuu’s Hunter Journal. Fortunately, Team Cherry designed this objective with some forgiveness: if certain foes have become permanently missable — such as those in the changing landscape of Verdania — the journal automatically exempts them from the requirement. This prevents the frustrating scenario of being locked out of the Memento due to oversight. Still, expect many hours of backtracking and grinding, as some rare spawns require patience to encounter enough times.

Sprintmaster’s Memento: Six Laps of Perfection

Fans who have collected all Mask Shards and completed the Sprintmaster’s initial races will have a sense of what awaits. Unfortunately, this Memento is simply a more grueling version of the third race, stretched to six laps instead of three. The course remains unchanged, but the extended duration magnifies any slip-ups. Liberal use of the clawline to maintain momentum and well-timed bashes against the Sprintmaster for a speed boost are essential. Since the challenge builds directly on previously learned routes, veterans should find it manageable with a bit of concentration, though the pressure of near-perfect execution over six laps is not to be underestimated.

Guardian’s Memento: Beating Seth’s High Scores

Arguably the most frustrating Memento of all, the Guardian’s Memento involves a recurring character named Seth. After the initial encounter just before the Nyleth fight, Seth does not perish but instead loses his memories and begins wandering Pharloom. You can find him in Greymoor where Shakra first sold the map, in Shellwood near the purple pollip challenge, in front of the Grand Gate, and finally in Fleatopia after completing the Ecstasy of the End quest. In Fleatopia, Seth becomes obsessed with the local flea games and posts his own high scores on the leaderboards. Players must surpass all his records: 55 in Flea Juggle, 95 in Flea Dodge, and 68 in Flea Bounce. These scores are significantly higher than the first set of flea challenges and require genuine mastery of each minigame. Once you have beaten every score, Seth will present the final Memento.

With all eight Mementos collected, return to the Bellhome and place them on the display wall. That empty space will finally feel complete, and the journey through Pharloom will have reached its truest conclusion. In 2026, the Hollow Knight: Silksong community continues to celebrate these achievements, and for good reason — they represent the game at its most demanding and rewarding.
