If you're aiming for 100% completion in Genshin Impact 7.1 Chapter VII: Act III, the most important thing to know is this:
The Northland Bank underground vault is a quest-exclusive area and cannot be revisited after the infiltration ends.
That means every optional chest, hidden interaction, and side reward inside the vault should be collected before progressing to the final confrontation with Pantalone.
This guide covers all 4 confirmed missable chests, the hidden ceiling passage, optional exploration, and the rewards many players overlook during the Northland Bank sequence.
Quick Answer
Before leaving the Northland Bank vault, make sure you've completed all of these:
- Opened 4 optional chests
- Discovered the secret ceiling passage
- Collected both High-Level Access Cards
- Completed the Walkie-Talkie diversion
- Opened the Exquisite Chest after the Fatui guard battle

Can You Revisit Northland Bank?
No.
The underground Northland Bank vault is only available during the Chapter VII: Act III Archon Quest. After the story advances beyond the infiltration, the entire area becomes inaccessible.
That makes this one of the few quest-exclusive locations where optional exploration actually matters. If you miss a chest here, you won't be able to return later and pick it up.
Missable Chest #1: Maintenance Corridor
The first optional chest appears shortly after entering the hidden maintenance tunnels.
Instead of following the objective marker, check the side alcove beside the green directional sign. An Exquisite Chest is tucked away here and is easy to miss because the quest points straight ahead.
Confirmed rewards
- Mora ×300
- Cryo Sigil ×2
- Instructor's Feather Accessory ×1
- Lucky Dog's Silver Circlet ×1
- Fine Enhancement Ore ×2
- Primogem ×5
- Mystic Enhancement Ore ×1
- Teachings of Charity ×1
- Mora ×1217
- Radish ×1
Missable? Yes — collect it before leaving the maintenance corridor.
Don't Miss the Secret Ceiling Passage
The secret passage is required for story progression, but it's still one of the best hidden interactions in Act III.
While searching the private lounge, you'll inspect several ordinary objects including:
- Exquisite Bottle
- Bank Brochure
- Logbook
- Bookcase
After enough investigation, Vesna notices something unusual above the ceiling. She flies upward, reveals a loose stone slab, and opens the hidden maintenance tunnel that bypasses the heavily guarded vault entrance.
Although it isn't a collectible, it's a memorable secret area worth documenting for completion.
Missable Chest #2: Vault Balcony
After clearing the first stealth section, you'll reach an upper balcony overlooking the enormous underground vault.
Look for the patterned rug near the railing—the Exquisite Chest sits directly on top of it.
Confirmed rewards
- Primogem ×5
- Mystic Enhancement Ore
- Adventurer's Flower
- Fine Enhancement Ore
- Mora
- Cryo Sigil ×2
This chest is much easier to overlook than it seems because the objective immediately leads you toward the next security corridor.
First High-Level Access Card
When the security terminal reports that two High-Level Access Cards are required, don't keep trying the locked checkpoint.
Instead:
- Enter the nearby office.
- Ignore the locked box, bookshelf, and picture frame.
- Inspect the desk beside the gramophone.
- Pick up the First High-Level Access Card.
If you're stuck on this puzzle, the dedicated access card guide walks through every employee sequence and laser checkpoint:

Walkie-Talkie Employee Diversion
After stealing the first access card, Pustova realizes it's missing and begins searching the room.
Rather than escaping immediately, use the Walkie-Talkie inside the marked blue interaction zone.
Vesna broadcasts a fake security announcement:
Remaining in restricted areas outside work hours is prohibited...
The warning convinces Pustova to abandon her search, creating a safe escape route without triggering combat.
This is one of Act III's most creative stealth mechanics and is required to continue the infiltration.
Missable Chest #3: Industrial Pipe Room
After escaping the employee search, you'll enter a darker industrial maintenance chamber filled with pipes and machinery.
Before climbing the stairs toward the objective marker, check the corner beside the large pipes.
Visible rewards
- Mora
- Cryo Sigil
- Instructor's Tea Cup
- Fine Enhancement Ore
- Primogems
The chest sits slightly off the main route, making it easy to run past while following Vesna.
Laser Security Section
The laser corridor isn't missable, but it's the transition point before the final collectible sequence.
Here you'll encounter:
- Red vertical laser barriers
- Automated security announcements
- Room 7 alarm broadcast
- The route leading to the second access card
Take your time navigating this area rather than sprinting through. The collectibles immediately afterward are more valuable than the checkpoint itself.
Second High-Level Access Card
Beyond the laser corridor is another secured office.
The Second High-Level Access Card rests on a desk and completes the pair required for the deepest vault checkpoint.
Once you collect it, the stealth sequence ends and the game's security response begins.
Missable Chest #4: After the Guard Fight
This is the most commonly missed reward in Act III.
After defeating the responding Level 90 Fatui guards, an Exquisite Chest appears in the middle of the hall before you head upstairs toward Pantalone's office.
Many players instinctively follow the objective marker and never notice it.
Confirmed rewards
| Reward | Quantity |
|---|---|
| Mora | ×300 |
| Cryo Sigil | ×2 |
| Lucky Dog's Goblet | ×1 |
| Adventurer's Pocket Watch | ×1 |
| Mora | ×1102 |
| Primogem | ×5 |
| Hero's Wit | ×1 |
Don't leave the room until you've opened this chest.
What Isn't Missable?
Several investigation objects appear during the lounge search, but they don't contain hidden rewards.
These are story interactions only:
- Exquisite Bottle
- Bank Brochure
- Logbook
- Bookcase
- Picture Frame
Feel free to inspect them for dialogue, but you won't lose any items by moving on afterward.
