The beauty of Dishonored 2 is that there are so many different ways to accomplish any given task. In the following mission specific walkthroughs you'll simply be seeing MY way of approaching each mission. There is no right or wrong way to doing anything in these missions. Use your best judgement and do what works best for your own personal gameplay and playstyle. I hope you enjoy the guide.

From what I've been told, the first two bonecharms that you can collect for this mission, while still on the Dreadful Wale are part of the Assassin's Pack (Pre-Order) DLC. i.e. If you did not pre-order the game, I don't believe you can get these. As such your end of mission counts might be less that what you see in the video. Just an FYI.

According to recent patch notes, the "kill bug" has been resolved. I would still suggest some farily liberal saving during this mission just so that you have decent save points to go back to and test just in case.

Also, when you get down into the basement Archives area, be careful tossing bottles of the flammable liquor at those bloodfly nests. If you have already taken care of Breanna, sometimes the two witches down there fall unconscious close enough to the nests to be hit and killed by the explosions when using said bottles. You can avoid the nests entirely by slipping into a small window shaped hole in the wall of the archives room that is down a small "hallway" to your right just before the nests (if you're coming from the side where the stairs/elevator are).

Keep in mind when you get into the Grand Palace itself that the Duke and his Body Double can spawn in one of five places and it is completely random as to what you get. The locations are as follows:

1. Private Garden
2. Throne Room
3. Duke's Office
4. Delilah's Chambers
5. Duke's Chambers

Below are some additional details on how you might handle the Duke and/or his Body Double based on where they spawn. These are just some high level thoughts on the matter. Do whatever works best for you.

=========================
Duke's Chambers
=========================
The same tactic works here whether it is the Duke or the body double. Eventually, the person in there will dismiss the single red shirt guard and then you can speak to or take out the one who is in there.

=========================
Throne Room
=========================
The same tactic works here whether it is the Duke or the body double. Get up on the first chandelier and wait. Eventually, the person in here will dismiss both guards. Once they are gone, Far Reach to the back left corner and remove the Whale Oil tank to disable the Pylon. Then you can speak to the body double. If it is the Duke, Far Reach up to the chandelier closest to the throne then do a drop take down on the Duke.

=========================
Dukes Office
=========================
The same tactic works here whether it is the Duke or the body double. Get into the room and either up on the chandelier or one of the display cases. Eventually, the person in here will dismiss both guards. Depending on what else you have to do in the palace, you might want to consider taking the guards out and not letting them be dismissed to wander about. They are an easy domino drop take down if you want it.

=========================
Private Garden
=========================
I've never seen the guards be dismissed from down here. If it is the body double, you see in the video how I deal with him. If it is the Duke, a Mesmerize 4 on the 3 people + the dog will work or you can just Domino the Duke and the 2 guards together as the dog is almost always looking away.

=========================
Delilah's Chambers
=========================
This is the rarest one for me. I reloaded this zone about 15 times and never got either one to show up here. If they do and the guards don't get dismissed use the same tactics I show for taking out the single guard in this area. Get up on the light fixtures to remove the guards and either take out the Duke or speak to the body double.
