On this page of our guide to Wolfenstein: Youngblood you will find a detailed description of Da'at Yichud Artifacts side mission. This mission concerns the search for the titular mysterious artifacts. There are four such objects to locate and they will be hidden in different parts of Laboratory X.
Who's commissioning the mission: Talk to Floor de Cloet in the hideout, in the catacombs.
Mission difficulty level: The game recommends 45 level of experience for this task. You can achieve this by completing other side missions, locating secrets, etc. You don't have to wait to get promoted to this level, because at least part of the mission can be completed in "stealth mode".
This task is carried out in the Siegturm / Laboratory X location, where you could unlock a fast travel point (metro station) - see separate pages of our guide for more information.
The exploration of Siegturm begins in the city, so you have to get back to the advertising pole and use the secret elevator in the middle. This will allow the sisters to move to Laboratory X.
The first artifact
There are 4 artifacts that have to be found and unfortunately each of them is in a different part of Laboratory X. You will have to go through a large part of this location again as a result.
The first artifact is on the ground floor of a section with long lab rooms. Previously, there were active laser firewalls here, which are now deactivated. The artifact is lying on one of the high machines.
The second artifact
The second artifact is in the next part of Laboratory X. Specifically, there is a section where a large robot was in the raid mission and where a laser cannon is located at the top of the stairs. You need to get to the room upstairs. The artifact is on the desk next to the PC.
The third artifact
The third artifact is located in the area with a large yellow gate. You have to visit a prison - there is a passage from picture 1 and additionally you have to use the Elektrokraftwerk weapon on one of the fuse boxes above the closed doors.
After you find yourself in prison, you must perform a double jump towards a large hanging lamp (picture 1). From the lamp you can jump to the upper balconies and get to the room above (picture 2).
The fourth artifact
The fourth artifact is located in one of the following areas of the lab. You must specifically reach the tunnel shown in the picture, which was examined during the main raid mission just before you found B.J Blazkowicz.
The artifact lies on the roof of a small isolated room in a corner.
Return with all four artifacts to Floor de Cloet (a fast travel option should be available at the location where the last one was found) to complete the mission.
