Hernand Castle Alchemist Chamber location
Hernand Castle can feel confusing at first due to its multiple corridors and similar-looking hallways, but the route to the Alchemist’s Chamber is actually quite direct if you follow the correct path. Once you enter through the main gates, your focus should be on reaching the first floor without getting distracted by side rooms or NPCs. The architecture is fairly symmetrical, which can make navigation tricky, but the right-side corridor is your key landmark here.
You don’t need to explore the entire castle—just stay focused on reaching the correct hallway and identifying the first accessible locked door.
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.
What you get from the chamber
| Reward | Description | Use |
|---|---|---|
| Faded Abyss Artifact | A mysterious relic tied to Abyss energy | Used for progression and upgrades |
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.
