Spoilers for Act 3 and optional late-game content. Most Mementos require endgame quests, optional boss fights, journal completion, or challenges—not just searching every room. This checklist covers the reported routes, highlights the prerequisites most likely to cause backtracking, and explains why guides differ on whether there are eight or nine Memento types.
How many Mementos are there?
There are eight Memento rewards in the broad checklist from PC Gamer. Silksong.codes lists nine named types, including both Conjoined Heart and Encrusted Heart, but says only eight can be collected in one playthrough because those heart rewards are mutually exclusive. The guides use different counting conventions; plan for one heart reward per run rather than expecting to collect both.
The routes below are reported by those guides, not verified here in-game. Several details have uncertain triggers, which are called out where they matter.
All Memento routes
| Memento | Activity and prerequisite | Route | Backtracking risk |
|---|---|---|---|
| Hunter’s Memento | Journal completion | Meet the required Hunter’s Journal entry count, then speak with Nuu at Greymoor Halfway House. | High if you leave journal entries until late; see the mode-specific counts below. |
| Craw Memento | Act 3 quest and optional boss | Complete The Dark Heart to make Craw Summons appear. Use it in the house at Craw Lake to reach the Court of Craws and the Crawfather encounter. | A Craw Lake gauntlet may also be required, but the guide presents this as uncertain. |
| Conjoined Heart or Encrusted Heart | Four Old Heart bosses and reward choice | Defeat Nyleth, Skarrsinger Karmalita, Crust King Khann, and Clover Dancers. The resulting Memento depends on how the four heart rewards are used; see the heart-reward notes below. | Choose carefully: guides describe the heart outcomes as mutually exclusive for a run. |
| Grey Memento | Silk Soar, Needolin, optional boss | In Sands of Karak, follow the rising platforms from a yellow orb to the hidden Watcher at the Edge. Play Elegy of the Deep on Needolin to start the fight; defeat the Watcher. | Requires late movement and the relevant Needolin ability. |
| Surface Memento | Needolin and difficult platforming | In the Nameless Town above The Cradle, play Needolin beside the corpse in the ruined house at the far right. The Memento drops from the ceiling. | Consider doing this during Passing of the Age, which the guide recommends as a way to avoid repeating the difficult approach. |
| Guardian’s Memento | Boss, appearances, and minigames | Defeat Shrine Guardian Seth while pursuing Heart of the Woods. Follow his later appearances, then complete Ecstasy of the End at the Festival of the Flea: beat his new high scores in all three flea minigames and speak with him. | Seth may skip intermediate appearances. If he is not at the festival, check his earlier locations. |
| Hero’s Memento | Hero’s Call quest and encounter | After meeting Garmond and Zaza, look for Hero’s Call on Bellhart’s board. At the Blasted Steps Bellway, follow Zaza to Garmond and finish the resulting encounter. | The prior Garmond quest state needed to trigger the quest is unclear in the guide. |
| Sprintmaster Memento | Swift’s races | Complete Fastest in Pharloom by winning Swift’s three races, then return for the additional race. Silk Soar opens the route through Hunter’s March. | The final race may require The Old Hearts quest. Performance-enhancing tools are unavailable during races. |
Hunter’s Memento: journal requirements
The Hollow Knight Wiki’s Hunter’s Memento reference gives the requirement as 230 Hunter’s Journal entries in Classic Mode or 231 in Steel Soul Mode. It says entries for Flintbeetle, Palestag, Shakra, Garmond and Zaza, Lost Garmond, and Lost Lace are not required. Once the applicable count is met, speak to Nuu at Greymoor Halfway House.

- Face over 200 ferocious foes! Beasts and hunters, monsters and knights. Defeat them all with bravery and skill!
PC Gamer suggests that completing the Bugs of Pharloom quest may also be necessary, but describes this as likely rather than certain. If Nuu does not award the Memento after the entry count is met, that quest is a reported additional condition to check.
Heart rewards: make the choice before claiming them
The four Old Heart bosses are Nyleth, Skarrsinger Karmalita, Crust King Khann, and Clover Dancers. PC Gamer describes a route in which the fourth defeated boss gives a heart reward as the Memento if the other three hearts were used for the quest; it also says taking all four hearts to the snail shamans results in Conjoined Heart. Silksong.codes names Encrusted Heart as the alternative heart Memento and says it cannot be collected in the same playthrough as Conjoined Heart. The guides do not use the same naming or counting convention, so do not assume both heart items are obtainable in one run.
Rank #2
- Hollow Knight: Silksong is the epic sequel to Hollow Knight, the award winning action-adventure.
- Journey to all-new lands, discover new powers, battle vast hordes of bugs and beasts and uncover secrets tied to your nature and your past.
Plan the late-game routes to limit backtracking
- Bundle Surface with Passing of the Age. The Surface Memento route involves a difficult platforming approach; the guide recommends collecting it while doing that quest.
- Keep track of Seth. His appearances can skip locations, so if he is missing at the Festival of the Flea, revisit places where he appeared earlier before abandoning Guardian’s Memento.
- Check Bellhart’s board after meeting Garmond and Zaza. Hero’s Call depends on that encounter, but the exact required Garmond quest state is not established.
- Leave room for late abilities and Act 3 quests. Silk Soar opens routes for Grey and Sprintmaster, Needolin is used for Grey and Surface, and Craw’s route follows The Dark Heart.
- Do not expect the races to accept tools. The guide says performance-enhancing tools are unavailable during Swift’s races.
Where Mementos go
Silksong.codes describes Mementos as decorative collectibles displayed in Bellhome and says a Desk is needed to display them. Its guide and PC Gamer both characterize many routes as late-game or Act 3 content. These display details come from third-party guides; no official Team Cherry checklist or statement confirming every secondary detail is cited here.
