Citadelle des Morts Main Quest

The Main Quest of the Citadelle des Morts follows Grigori Weaver, Elizabeth Grey, Mackenzie Carver, and Maya Aguinaldo as they explore an an ancient castle located in the Principality of Avalon that is controlled by the French Syndicate, in order to locate Gabriel Krafft in the hopes that he can lead them to the Sentinel Artifact.

Prerequisites

Before beginning the main quest, players must unlock the Pack-a-Punch Machine and obtain all the The Bastard Swords and Incantations. Much of the Quest can be done before the Bastard Sword and Incantation are complete, but the final step before the boss fight requires all of them.

Starting the Quest

1. Speak to Gabriel Krafft by interacting with a door in the Dungeon. This door is in the small hallway behind Quick Revive. While Speaking with Krafft, Zombies will not spawn.
2. Grab the 4 Torn Pages from the Sitting Rooms. The specific pages will always spawn in the same general area of the room every game.
   1. Page I (Top Left) - Against the walls and boxes near the door leading to Entrance Hall
   2. Page II (Bottom Left) - Around the bunk beds
   3. Page III (Top Right) - Around the TV stand/sofa and TVs next to Stamin-Up
   4. Page IV (Bottom Right) - Against the corridor wall between Alchemical Lab and the Oubliette
      1. If one wants to save some time skip the following step, note which pages have which eye symbols without picking them up and skip to Step 6. Note that the 4th and final page will always correlate to the Point of Power trap in the Sitting Rooms.

Step 1: Alchemical Symbols

1. Melee the off-colored square on the wall in the Undercroft with a Melee Macchiato punch to reveal a grid of alchemical symbols.
2. Enter a 6-symbol code by shooting the symbols in the correct order. Travel to the Tavern, there are 6 dark green flasks labeled "I" through "VI". Interacting with these flasks to reveal a blue alchemical symbol from the grid. Return to the Undercroft and shoot the corresponding symbols in the proper order. After shooting the first symbol, the symbols will switch places and will continue to do so every few second and after every input, but there is no consequence for a missed shot.
3. If done correctly, an orb will open a part of the wall on the left side of the grid, revealing an opened book with missing pages. Interact with the book to place the 4 torn pages.

Step 2: Points of Power

1. Each Torn Page shows a specific Point of Power Trap on the map based on the shape of both the eye and its background. Following the pages in numerical order, head to each indicated trap. Activate a trap and get about 10 kills. If done correctly, a quote will be played and the trap will immediately shut down. The corresponding symbol will turn grey confirming the step was done correctly. Once all traps are done, an orb holder with four symbols will spawn on the wall between the Sitting Rooms and Oubliette.
   1. The final trap will always be located in the Sitting Rooms, saving players time figuring out the other three.

Step 3: Honoring the Dead

1. At this point, one must obtain all 4 Elemental Swords and all 4 Incantations.
2. Examine the code around the orb holder. The code consists of the symbols of each Bastard Knight (Dragon, Stag, Raven, Lion), marked I-II-III-IV clockwise. This is the order in which is needed to interact with each Knights statues. The knights and their respective incantation and sword are in the table below.

Knight	Incantation	Sword
Stag	Electric	Durendal
Raven	Dark	Balmung
Lion	Light	Solais
Dragon	Fire	Caliburn

1. Cast the corresponding incantation in front of each statue in the Dining Hall while holding the respective Elemental Sword. Then, quickly start the Swords inspect animation while staring at the knight, the animation doesn't need to be played entirely. Successfully doing this will cause the knight to salute and glow. Repeat for each knight in the order displayed around the orb holder.

Step 4: Elemental Challenges

1. Once all the statues are done, a white Mystic Orb will appear above the room before being lowered down by the statues. Bring the orb to several holders found near the different incantation ritual sites. Insert the Mystic Orb into the holder to start the corresponding elemental challenge. Once a challenge is successfully completed, a small colored energy orb will orbit the Mystic Orb.
   1. Fire: bring the orb to the holder next to the trap in Courtyard. Get kills by burning Zombies with Caliburn, Molotovs, Fire Incantation, or the Napalm Burst ammo mod.
   2. Void: bring the orb to the holder next to the Dark Incantation ritual in the Undercroft. Get kills with Balmung's charged attack, Void Incantation, or Shadow Rift ammo mod.
   3. Electricity: bring the orb to the holder against the gate next to Light Incantation ritual in Town Square. Get kills with Durendal's charged attack, Electric Incantation, or Dead Wire ammo mod. Kills on zombies affected by Shock Charges or the Tesla Storm field upgrade may also count.
   4. Light: bring the orb to the holder located above the gate in Dining Hall, opposite of Vulture Aid. Green orbs will start to appear, run across the different orbs around Dining Hall as fast as possible.

Step 5: The Owl

1. Once all 4 elemental challenges are completed, place the Mystic Orb in the wall between the Sitting Rooms and the Oubliette. The wall will open to reveal a hidden room, the Secret Study. Interact with the Ancient Mystic Recording on the stone table. A spectral form of Guy de Saint-Michel will appear congratulating his "favorite son" for completing his trial.
2. Pick the Guardian Key on the table and bring it to the statue in the Town Square.
3. At the statue's feet, there is an eye symbol which allows the key to be deposited, which will activate and enter the boss fight.

Step 6: The Guardian

Context

1. Upon activating the boss fight, the statue in the middle of the Town Square will begin to move, revealing itself to be The Guardian. The Guardian will jump forward and smash it's axe into the ground, transporting the players to the Boss Arena for the Quests.
2. In the Boss Arena, the Guardian will be constantly attempting to hit the players with his hammer, zombies will continue spawning, and as players progress the playable area will flood more and more with lava limiting the players mobility.
3. Boxes with charges for all four incantations will spawn in the middle of the arena, as well as an Ammo Box.
4. Much of the boss fight involves attacking The Guardians weak points to deliver critical damage. These weak points are depicted as glowing parts of The Guardians body and can be in any of the following locations.
   1. Shoulders
   2. Wrists
   3. Chest
   4. Knees

Boss Fight

1. Upon initially entering the arena and being confronted by the Guardian, players will see that they are able to shoot him and damage him. Get behind the Guardian and shoot him in the back to eventually break a seal on his back, causing him to take more damage.
2. Various body parts of The Guardian will begin to glow. Players should attempt to focus fire on these areas as they will deliver critical damage, but non-critical damage will still impact The Guardians health bar.
3. After a period of damage, The Guardian will stop moving but also go immune. All players have to do during this time is survive against the Zombies that will spawn.
4. The Guardian will re-awaken and begin attacking players again, he will now have the ability to shoot geysers of lava randomly out at players.. Players must continue moving around, focusing on his weak points and avoiding his attacks. This phase is very similar to the first phase, but the lava flowing into the room will begin limiting the playable space.
5. In the final phase, the Chest becomes the Guardians only weak point, but the battle is otherwise the same. Shoot the Weakpoint until The Guardian is dead.

The cutscene will then play, signaling the completion of the Main Quest.
