Hernand Castle Alchemist Chamber location
The Alchemist’s Chamber is located inside Hernand Castle in the Hernand region. After examining the engraved Mystical Key, your objective updates and sends you toward the castle.
Before you attempt to enter, you need to equip the Hernandian Attire from your inventory. Without it, the guards at the gates will refuse entry. Once equipped, the guards allow Kliff to pass through both checkpoints leading into the main castle grounds.
Inside the castle, take the first doorway on the right and head upstairs to the second floor. After reaching the upper hallway, turn right again. You will see several locked doors along the corridor. The correct room is the first door on the left. That door leads directly into the hidden Alchemist’s Chamber.
How to reach the Alchemist’s Chamber in Crimson Desert
Step 1
Enter Hernand Castle through the main entrance and proceed forward until you reach the interior stairway leading to the first floor. Avoid detours, as none of the side paths are required for this objective.
Step 2
Once on the first floor, immediately look for the corridor on the right-hand side. This is the only path you need to follow for this part of the quest.
Step 3
Walk into the corridor and carefully count the doors from the entrance. The chamber you’re looking for is the very first door on your left. This detail is important, as there are multiple similar doors further down.
Step 4
Use the key you previously obtained during the Mystical Key questline to unlock the door. Without this key, you won’t be able to proceed, so make sure you’ve completed the prerequisite steps.
Step 5
Enter the room to discover the Alchemist’s Chamber, where a treasure chest awaits you. Open it to receive the Faded Abyss Artifact.
Step 6
After collecting the artifact, observe the chamber as an Abyss portal activates within the room. This portal is your gateway to the next phase of the quest.
Rewards and unlocks from the Alchemist’s chamber
| Reward | Use |
|---|---|
| Faded Abyss Artifact | Allows attribute or build adjustments |
| Abyss Portal Access | Unlocks the next main storyline section |
| Polar Opposites Quest | Continues the Chapter 1 progression |
The Faded Abyss Artifact is not just a collectible—it plays a meaningful role in advancing deeper Abyss mechanics and potentially unlocking future upgrades or interactions.
What happens after entering the Abyss portal
Once the portal appears, your objective shifts from exploration to progression. Entering it will move you forward in the Mystical Key questline, typically leading to a more challenging area or puzzle sequence tied to Abyss mechanics.
You should be prepared for increased difficulty or environmental hazards after stepping through, as Abyss-related zones often introduce new gameplay elements. This is where the quest begins to evolve beyond simple exploration and into more complex encounters.
The Alchemist’s Chamber acts as a transition point between standard exploration and deeper Abyss-focused gameplay. Missing this location can halt your progress entirely, making it one of the most important hidden rooms tied to the Mystical Key quest.
It also reinforces the importance of revisiting structured interiors like castles, where hidden progression points are often tucked behind locked doors rather than marked objectives.
