Genshin Impact 7.1: How to Sneak Into the Vault in One Move Left to Make

The Northland Bank break-in is the one part of Chapter VII, Act III where combat stops mattering. During the Sneak into the vault objective in One Move Left to Make, the game strips your party down to a single trial character and drops you into a stealth sequence built around searchlights, patrolling guards, and a walkie-talkie you can only use in specific spots. Get spotted and you restart the segment; play it properly and you reach the vault door in about ten minutes.

Quick answer: Use the walkie-talkie inside each blue zone to pull guards off their posts, collect both High-Level Access Cards, then press Open Door at the vault entrance to trigger the Marozov cutscene.

What the vault stealth section locks you into

This is step 15 of One Move Left to Make, the third subquest of Chapter 7 Act 3, White Night, Like a Dream Upon Waking, which arrived with Version 7.1 on September 23, 2026. The act itself only unlocks after you finish the Act 2 quest Wraith’s Nocturne.

Your active party is reduced to Traveler (Cryo) as a trial character for the whole segment.
Vesna stays with you over the radio rather than as a playable unit, and she is the one who makes the fake reports.
You are in Stealth gameplay, so guards, patrols, and searchlights all count as detection.
Crouching and staying behind cover is the intended way to wait out a guard who walks into your room.

How the walkie-talkie and blue zones work

The walkie-talkie is not a free-use item. Each time it becomes relevant, the floor lights up with a glowing blue boundary and the prompt The walkie-talkie can be used within the blue boundary appears. Step inside that area and the interaction becomes available.

Every call is a diversion. Vesna reports a problem somewhere else in the bank, and the guard blocking your path leaves to check on it. The report changes to fit the situation, so you get a different excuse at each zone rather than repeating the same one.

If the prompt is missing, you are standing outside the blue boundary. Walk further into the glow rather than looking for another interactable.

Sneak into the vault: full stealth route

Follow the quest marker and move through the corridor of searchlights and patrolling guards. Time your runs through the gaps between the light cones instead of sprinting straight down the middle.

Step into the first glowing blue area and use the walkie-talkie. Vesna calls in a fake security breach on Safe 973, which clears the guard ahead of you.

Climb the stairs to the next blue zone and make a second call. This time the report is a failed locking mechanism on Safe 501, pulling the next guard off his post.

Walk up to the control terminal and choose Place Access Card to open the door ahead. Before moving on, loot the Exquisite Chest sitting inside the newly unlocked room.

Once inside the office, check the counter after the hint This room might contain access cards. Search around appears. Interact with the card there to collect the High-Level Access Card.

Guard Pustova walks in looking for the missing card. Crouch immediately and keep the large chests between you and her until she stops searching your side of the room.

Move up to the upper deck and use the walkie-talkie again. The unauthorized access warning spooks Pustova and she leaves the area entirely.

Drop down into the ventilation and maintenance shaft below. Follow it to the far end and climb the vertical ladder to reach the upper security area.

A Warning Broadcast fires as you arrive, switching on red laser grids across the hallway and updating the objective to Find the second access card at the target location. Watch the beams move and walk through the gaps rather than dashing.

At the end of the laser hallway, enter the office and take the second High-Level Access Card from the desk beside the lamp.

Head to the vault door and select Open Door. This ends the stealth run and starts a cutscene in which guard Marozov catches you.

Chests and pickups along the route

Nothing here is required to finish the objective, but all of it is easy to walk past and awkward to return for once the quest moves on.

Pickup	Where to find it
Exquisite Chest	Room unlocked by the access card terminal
Common Chest	Lower ventilation and maintenance shaft
Radish	On a steam pipe in the maintenance area
Progress report	Desk documents covering Snezhnograd construction
Maintenance notice	Underground heating system notice in the shaft

How to confirm the stealth section is finished

The stealth segment ends the moment the Open Door cutscene plays. Once Marozov spots you, the quest tracker switches from Sneak into the vault to Defeat the guards that have come, and the party control changes as well, handing you Vesna as the trial character for the fight.

That fight runs across two waves. Clear both and the objective flips back to Sneak into the vault for the short stretch that follows, leading into the chase after Regrator. If you are still seeing searchlights, guards on patrol, or Traveler (Cryo) locked in as your only character, you have not reached the vault door yet.
