Contaminating the bootleg elixir in the Bottle Street Gang's headquarters | Mission 2 - High Overseer Campbell Dishonored Guide
Last update: 11 May 2016
The Bottle Street Gang's headquarters is located in the [Dunwall Whiskey Distillery] that you may have already found. You need to backtrack to the alleys near Granny Rags' house and the place where you met Griff. The entrance to [Dunwall Whiskey Distillery] is shown in the above screenshot.
The distillery is occupied by gang members and, unfortunately you need to expect them to be hostile towards you. If you intend to eliminate the gangsters, I'd strongly recommend using your crossbow and eliminate them from distance. The main encampment is occupied by five gang members, plus two at the entrance, who will start to patrol the area only as soon as you come near the. Regardless of whether you decide to kill the gang members or just to overpower them, I recommend that you hide the bodies afterwards. This will ensure that nobody will find them afterwards. It's also worthwhile to loot the bodies for gold and two distillery master keys.
Fortunately, there's an easy way to go around the gang members if you don't want to kill them. You can go past the gangsters, and near the distillery entrance, using pipes (the above screenshot), or on roofs of nearby buildings.
If you have the opportunity to, I'd recommend exploring the entire area in front of the distillery entrance. Inside the roofed area to the left of the starting point, you can find gold, food, sleeping bolts, distillery master key and a book. To the right of the distillery building, there are a projectile launcher, gold and one more key. To the left of the entrance, there is an enclosed area (the above screenshot) that may be opened with the key. Inside, there is a Sokolov's health elixir, gold and a rewire tool.
You can infiltrate the distillery in two ways. You can either enter through the main entrance (the above screenshot), or use Possession on one of the nearby rats, in order to gain access through the ventilation system.
If you have decided for the variant with the main entrance, go straight ahead and stop in the spot shown in the above screenshot. It is a good idea to perform a slide underneath the tripwire in order to reach a projectile launcher and disarm it. If you've infiltrated the distillery via ventilation system, you will end up in a small storage room. It is a good idea to loot it for food, gold, Sokolov's health elixir, Piero's spiritual remedy, bullets, spring razor and two grenades. I also recommend the control room on the right, where there is food, gold,a recipe for Craxton and a key.
You now need to decide on the path you want to take to reach the area, in which you need to contaminate the elixir. It is much better an idea to choose the passage on the right that can be accessed through the blue door. Watch out for two nearby guards and, at least one, additional enemy patrolling the corridor between you and your destination (the above screenshot). There also is one trap to disarm/avoid. You can also find gold and Piero's spiritual remedy there.
It is much more difficult to reach the door on the upper balcony (the above screenshot). You'd have to watch out for two guards on the main level, a single one on the lower one,and one or two more gang members on the balcony itself (one of them moves around between rooms). It is good news, however, that you can get there not only by using stairs but also by climbing the chain.
I'd recommend that you explore the upper room before you go about contaminating the elixir. It is the one that may be guarded by a single guard. Inside you can find food, gold, Pieroas spiritual remedy, a book and a bone charm. Obtaining the charm is, unfortunately, very troublesome, because you need to blink (teleport) to the beam underneath the ceiling (the above screenshot).
Having taken care of All the business, you can now return to the abovementioned corridor with the trap in it, and find the entrance to a small room underneath the stairs (the above screenshot) (you may enter either using the key or performing a slide). First, turn your attention to gold, bootleg still instructions, a spring razor, Sokolov's health elixir and a book.
An interesting piece of information is that, before you contaminate the tank, you can make a few elixirs for yourself. To do that, you need to pick up an empty elixir vial, drag it towards the machine, put it in the slot and choose the middle option after you put it in the slot. If you just want to contaminate the elixir, everything you need to do is choose the uppermost option after you interact with the valve (the above screenshot).
New optional quest: Visit Granny Rags for your gift
New optional quest: Collect your gift from Granny Rags
You may now leave the distillery. Be careful though because you may run into an trouble if you've missed an enemy on your way here, or failed to hide a body correctly. Go now to the Granny's place (near the first wall of light) and start a conversation with her. The woman will direct you to a room upstairs for your reward. Just like in the case of the previous quest, your gift is a rune. You may now return to the square separating both walls of light and focus on the main quest again.
