After accepting the request in Honkai: Star Rail, you decided to give the Haunted House a visit and ended up having to open the safe to retrieve the house deed for Renault. But before you can, the deed is locked a puzzle with numbers and letters that needs solving. We’re going to finally reveal the answer to the puzzle in this guide!
Open the Safe & Take Out the Deed
Before you can open the safe, you have to get the hint by unlocking the courier package snucked in the corner of the room here.
Use the Old Bell and then the Square Rice Ball to get the Rubbing Paper from the invisible creature.
Then, head to the first room you started in to decipher the Stele. This is how you get the hint to the puzzle that was left behind by Renault.
If you’ve been racking your brain about this, perhaps it’s best to not overthink it. Below is a hint of the M and N mean along with the numbers.
Get it? That’s right, it’s just the shape made on the numeric keypad. Using this hint, we can now draw T on the keypad and get 1328. Input that and you’ll unlock the box. Alternatively, you can input the wrong number to get additional interaction with Sushang.
That’s how you “Open the Safe & Take Out the Deed” in the Haunted House session in Honkai: Star Rail.
