This page of the guide to Resident Evil Village contains a description of the first puzzle from House Beneviento. The following walkthrough will teach you how to initially examine the large doll woman, how can you use the found Blood Covered Ring and how to get out of the room with Mia's doll.
In House Beneviento, there are several puzzles that you can complete almost in a row (with small exploration breaks). You will start solving them after you enter the dollhouse and use the elevator that goes to the basement.
Eventually, you will reach a room with an surgery table, where you will find a large doll resembling Mia (Ethan's wife). If you try to take the yellow jar, you will temporarily lose your whole inventory. Moreover, the door to the room will lock behind you and you will have to figure out how to get out.
There are quite a few interactive places to explore on the large doll's body, not all of which need to be examined right away, as you won't have all the items necessary to interact with the doll. Start by examining:
- Right Arm - Breaking off a piece of it will give you the Silver Key.
- Left Hand - Ethan can pull the Blood Covered Ring off one of the doll's fingers. This is the most important item.
Now go to the door of the adjacent room (the one separated with a lot of windows). Ethan can use the Silver Key to open the door.
Once you're in the next room, go to the Sink and use the ring taken from the doll on it. The blood on the ring will be cleaned off.
Select the ring from the inventory to Examine it. You will find an engraving of the combination 052911.
Return to the room with the large doll and use code 052911 on the lock. This will allow Ethan to return to the other rooms in the basement.
