Exploring the neighborhood of Sokolov's apartment | Mission 4 - The Royal Physician Dishonored Guide
Last update: 11 May 2016
The district that Sokolov's apartment is located in is quite vast, but you'd better not neglect to explore it thoroughly, because you may find many valuable items here. To start with, a few words concerning the dangers here. The guards are concerned with patrolling the main road and guarding cages with civilians in them (the above screenshot). That is why you shouldn't leave unconscious guard at the main road if you intend to eliminate them. Soon enough (after you free the civilians) this might cause the bodies to be inadvertently discovered.
It's best to deal with the imprisoned civilians later on, after you get rid of all guards. Otherwise, this would unnecessarily lead to alarm being raised, and guards would also attack the escaping civilians. Disable the wall of light by removing the whale oil tank and listen to the conversation with one of the rescued civilians. You will learn about whereabouts of a nearby safe.
New optional quest: Open the safe hidden behind the painting
You now need to teleport to the highest located balcony of the destroyed building, at the foot of which the civilians were held. You will recognize the place by a big painting (the above screenshot) hanging here. Move the painting and enter the combination (294). In the safe there is gold and a note (Secret Stash Tip) containing information about the whereabouts of another stash.
Return downstairs and enter the building to the left of your starting point, i.e. the one that the rescued civilians returned to. On the ground floor there is gold and food. Next engage in the actions you learned about from the note that you found on the roof. Approach water tap (the above screenshot) and interact with it three times. This will result in a secret chamber being opened. Watch out though for the rats dashing from inside. After you eliminate or escape from them, you can explore the chamber itself. Inside there are gold and Piero's spiritual remedy.
Unfortunately, you cannot use the stairs to reach the upper floors of the building with the liberated civilians in it, because it is blocked. Instead, you need to go back outside, go towards the river bank and reach the balconies outside, shown in the above screenshot, using teleportation and nearby runes. Resume the exploration of the building to find gold and a bone charm.
It is not the end of the exploration, yet. I recommend that you also explore the warehouse at the other side of the street from the building that civilians were kept in. It's best to take the door near the active spotlight to access it (the above screenshot), although you can also get inside from rooftops. Inside you can find gold, food and Piero's spiritual remedy.
