Mementos are special collectibles in Hollow Knight: Silksong, found only in Act 3. These in-game trophies can be displayed in your Bellhart home, but most do not affect game completion or achievements. Only two mementos—the Hunter Memento and Hero’s Memento—are required for achievements; the rest are optional for completionists and lore fans.
Below is a comprehensive guide to all 8 mementos and how to obtain each one:
1. Sprintmaster Memento
Challenge the Sprintmaster in Far Fields during his quest (which awards a Mask Shard). After completing the initial race, return and challenge him again for a tougher rematch: this time, the third race has 6 laps instead of 3. Win to earn the memento.
2. Guardian Memento
Defeat Seth as part of the quest to obtain three hearts; he guards the Heart of the Wood and appears around Pharloom. After beating Seth, you must surpass his scores in the Flea Games in Fleatopia. This is a tough challenge, but necessary for the memento.
3. Hero’s Memento
Complete the Hero’s Call sidequest. The exact trigger for this quest is unclear, but it involves finding Garmond & Zaza in various locations throughout your journey.
4. Hunter Memento
Defeat every enemy enough times to fill out all entries in your journal, similar to the original Hollow Knight’s Hunter’s Mark. This is a grind, but required for an achievement.
5. Gray Memento
Defeat the Watcher at the Edge, a secret boss in the left-center part of Sands of Karnak. You’ll need to use Soar to reach the area, and then play the Needolin to awaken the boss.
6. Surface Memento
Return to the top of the Cradle using Soar. After challenging Grand Mother Silk, continue upward through Silksong’s version of the Path of Pain (less difficult than the original). At the end, go all the way right and play the Needolin to receive this memento.
7. Craw Memento
During Act 3, you may receive a Craw Summon near any bench. Once you have it, go to the Craw House in Graymoor and complete the gauntlet challenge. The exact method to obtain the Craw Summon is unclear, but it may be related to collecting your last missing tool.
8. Conjoined Hearts
Complete the Green Prince sidequest, which can be started as early as Act 1 by freeing him in Sinner’s Road. The final step is to find the prince to the right of the Craw House, where you’ll also discover the Verdania map. During the main quest, you need three hearts for the ritual, but four are available; the unused heart becomes a memento for your house.
