In the expansive world of Genshin Impact, quests often hide intricate puzzles that reward attentive players with unique discoveries. One standout challenge appears in the Lasting Promise storyline, where travelers must pinpoint unusual locations guided by subtle notebook clues and interact with them in specific ways. This guide breaks down the process comprehensively, ensuring you navigate the underground areas near Inazuma Castle without frustration.
Understanding the Lasting Promise Quest Context
The Lasting Promise quest ties into Ayaka’s narrative arc, pulling players into secretive caverns beneath Inazuma Castle. After reaching the marked zone from your notebook, the objective shifts to scanning for oddities. These aren’t random; they’re tied to environmental cues like colored foliage and stone formations. Success here advances the plot and grants items such as Adventure EXP, Mora, Hero’s Wit, and Mystic Enhancement Ore.
Players often arrive at a spacious cavern with multiple paths. The key is observation: look for anomalies that stand out against the natural terrain. This phase tests your ability to interpret vague descriptions into actionable steps, blending exploration with puzzle-solving.
Spotting Anomalies in the Cavern
Once inside the underground section, orient yourself by facing the southeastern exit. Instead of rushing ahead, turn your attention northward to elevated platforms. Blue-tinted bushes mark the first clue, glowing subtly against the rocky backdrop. These shrubs frame suspicious stone walls, which are the real targets.
There are typically three such walls positioned north, east, and south. Each interaction triggers companion dialogue, like Paimon’s remarks, confirming you’re on track. Approaching the wrong one won’t progress the quest, but it won’t penalize you either—simply try another.
- North wall: Primary spot with prominent blue shrubs nearby.
- East wall: Secondary option, accessible after initial checks.
- South wall: Final fallback, often mirroring the others visually.
Interact with the bushes first to highlight the wall, activating the investigation prompt. Patience is crucial; rushing past these markers leads to repeated failures.
Mastering the Knocking Sequence Puzzle
The core mechanic involves a rhythmic knocking pattern on the conspicuous stone wall. Options appear as ‘knock once,’ ‘knock twice,’ ‘knock four times,’ or ‘knock seven times.’ Random attempts waste time, as incorrect choices yield no response or neutral feedback like ‘The stone wall does not react’.
The solution hides in the notebook hints. Review Ayaka’s notes or companion suggestions—numbers like 1, 4, 7 appear in blue ink, matching the successful sequence. Execute it in order: once, then four times, then seven times. This destroys the rock barrier, revealing a passage or chest.
| Attempt Order | Knock Count | Outcome |
|---|---|---|
| 1st | Once | Wall cracks slightly |
| 2nd | Four times | Further weakens |
| 3rd | Seven times | Barrier shatters, path opens |
If you select wrongly, such as twice, Paimon advises recapping the notebook. Repeat on the same or nearby wall until correct. Videos confirm this works across instances, with the third wall often leading to the main reward.
Navigating Multiple Wall Challenges
Don’t stop at one success—the quest prompts continued searching. After the first breakthrough, scan for additional blue bushes on opposite rock faces. Another wall awaits, requiring the identical 1-4-7 pattern. This unlocks a mysterious box or notebook update, advancing to exterior checks.
Common pitfalls include:
- Missing elevated ledges with blue indicators.
- Knocking out of sequence, resetting progress.
- Overlooking companion hints post-failure.
Pro tip: Mark walls with custom waypoints for quick retries.
Rewards and Progression After Success
Completing these steps yields tangible gains: 525 Adventure EXP, 35,475 Mora, 4 Hero’s Wit, and 8 Mystic Enhancement Ore. The story progresses to opening chests and exiting for further objectives, deepening Ayaka’s lore.
Post-unlock, the cave reveals hidden passages tying into larger Inazuma secrets. This mechanic echoes other Genshin puzzles, training players for future riddles.
Troubleshooting Common Player Issues
Stuck players frequently report no reactions. Ensure:
- Quest marker is active.
- Blue shrubs are investigated first.
- Sequence matches blue-highlighted numbers exactly.
If issues persist, relog or fast-travel away and return—occasional glitches resolve this way.
