Dishonored 2 Mission 8, also known as The Grand Palace, is available after you discover Delilah Copperspoon’s secret from the séance that took place in Aramis Stilton’s Manor three years ago, by playing the mission A Crack in the Slab.
Duke Luca Abele, Delilah’s last ally and the ruler of Serkonos, is the one who orchestrated the coup against you. He lives in the Grand Palace, where you have to find and eliminate him. However, he uses a body double to protect himself against assassins.
Moreover, now that you know the secret to Delilah’s immortality, you must also locate her spirit which is held in the Duke’s hidden vault.
The mission is split in two parts, one that takes place on the Ravina boulevard, and another inside the actual Grand Palace. Both areas are filled with collectibles.
The text hints and screenshots featured in the next Dishonored 2 collectibles guide reveal the locations of all collectibles found in both regions. We recommend using the guide in the same order as below. Play the YouTube video at the end of the guide if you want an accurate pathway for the harder collectibles.
Mission 8 – The Grand Palace Collectibles Locations
From the skiff, follow the path until you reach the enemy checkpoint and head right. Go up the alleyway to find the Winslow store.
Blink/Far Reach on the balcony across the store and open the vise inside the room to release a Black Bonecharm, the first collectible in Mission 8.
Outsider Shrine #1, Rune #1, #2
Follow the road from Winslow store to find the black market shop in an alley to the right side of the street. While facing the black market entrance, jump on the crates on your left side to reach a grassy area.
Break the wooden boards here to find a cave. Step inside and interact with the Outsider Shrine to collect two Dishonored 2 Runes.
Back in the main street you find the Wall of Light and a Watchtower security device. Go to the third floor of the building that has the Windmill on the roof. The apartment has the entrance blocked with wooden boards since it’s infested with Bloodflies and a Nestkeeper.
An alternate entrance is from the balcony overlooking the Watchtower which is easy to reach using Blink/Far Reach. The Rune is inside a drawer in the bathroom.
In the bedroom at the back of the apartment is a Painting hung on the wall across the bed.
Near the Wall of Light, at street level, there is a stall. Check inside for an extra Blueprint if you missed it in a previous mission.
Backtrack to the Winslow store and get the shopkeeper’s apartment key from the cash register. Make your way back to the Wall of Light and head to the third floor of the building closest to it.
Unlock the apartment using the key and check the regular desk in the well-lit area to find a Dishonored 2 Mission 8 Blueprint.
In the same apartment as above, find the bed that holds a Bonecharm collectible. Swing your sword to knock aside the pillow and grab the collectable.
Go to the third floor of the adjacent building to find another Bonecharm. It’s inside a drawer in the bathroom that’s on your left-hand side as you enter the apartment.
Next, leave the Ravina district to go to the Grand Palace. Enter the palace using the front doors. From the large dining room in the middle of the area, head left to find the throne chamber.
Blink/Far Reach to the farthest lion statue on the left to avoid an Arc Pylon security device and disable it by removing the whale oil tank. After that, look on the throne to find the Bonecharm.
Go back to the dining room, but this time head right. Just before the stairs that lead to the upper floor is a small suite. The Dishonored 2 Bonecharm is on one of the round beds found inside, next to a dead woman.
Again, from the dining room, follow the staircase on the right side of the area to reach the pantry in the basement.
Look for a secret button in one of the shelves along the wall to open the Duke’s hidden Vault. You can find the Blueprint on the table in the main room of the vault.
Inside the vault there is a small adjoining room. Search the room to find an altar and a Black Bonecharm.
Break the dressing screen/divider next to the altar mentioned above to reveal an abandoned storage that is flooded. Swim underwater to find the main room.
The Dishonored 2 Mission 8 Rune is in a small alcove filled with wine bottles. Alternatively, you can find the flooded storage by breaking the barricade in the private gardens (near the throne chamber).
Use the elevator in the dining room to reach the third floor, “Offices & Guest Rooms”. Enter Delilah Copperspoon’s chambers using the door that’s opposite to the lions at the end of the corridor.
Hug the left wall or her chambers until you find the bathroom. Open the drawer under the sink to find a Corrupt Bonecharm.
On the other end of Delilah’s chambers is a room with a piano. The Painting collectible is tucked in a corner near the piano.
From the previous collectible, exit to the stairwell and get in Duke Luca Abele’s office (mind the clockwork soldier inside). Between the two bookshelves is a drawer under a window. Open it to find the last Blueprint in Mission 8.
The last Painting in The Grand Palace is also in the Duke’s office. It’s hung above the fireplace, on the left wall as you’re facing the blueprint collectible from above.
While still in the office, grab the combination of the First Captain’s safe from a side desk. Use the elevator to get to the first floor, and head outside using the double doors at the back of the dining room.
In the garden, follow the left wall, then enter the First Captain’s chambers using the small windows close to the floor (or you can enter from the throne room). Unlock the safe to get a Rune, the fifth and final one in Dishonored 2 Mission 8.
