Start the exploration of the location by entering a large building. Start to exterminate the undead scarabs and look around, the location for the chest. Now proceeds to the next room where there are even more difficult fights for you to fight.
The battle here consists of two parts. For starters, you will have to eliminate two skeleton champions. Take advantage of the fact that there aren't quite a few huge pillars this room, which you can easily take cover behind. Just like in the case of bottles with other champions you can of course make use of your death grip.
the other part of the battle is fighting the undead general. Also in this case, you should remember perfectly how to behave. Especially, I remind you about avoiding his formidable charges, but thanks to the above-mentioned pillars, it is going to be even easier. That is the case of battles with previous monsters.
After you are done-explore the entire room and find the page from the book of the of the dead hidden behind destructible objects (side quest [The Book of the Dead]). You can now start solving another puzzle. Position yourself on the pressure plate shown in the above screenshot, and launch Soul Split (the point here is to add permanent building to the pressure plate with the physical form of the Death).
Switch to the other half of the soul (press and hold down E key), and find the area shown in the above screenshot, where you can start climbing. Use interactive agents to reach a small balcony and Hughes the switch that you find there. You may now return to your physical form and go through the newly opened Northern room.
The location you have just entered is the central part of the city of the dead . So you will be returning here very often (on the same and other levels). There are a few spawns around, but they are no virtual threat. Explore the room for a Relic of Renagoth (side quest [Lost Relics]), and go down in the Western corridor shown in the above screenshot.
