| Key Items | Reactor Cube, Reactor Pillar |
| Completion Trigger | Reactor activation |
Crimson Desert Sanctum of Expiation location
As you approach the Sanctum, you’ll immediately notice its ruined and overgrown structure. The entrance is partially blocked by environmental elements, which already hints at the puzzle mechanics involved.

The reactor itself sits at the center of the Sanctum, incomplete and inactive. You’ll see two empty slots—these indicate the missing components you must locate.
How to complete Sanctum of Expiation puzzle in Crimson Desert
1 – First piece location
Step 1
Enter the Sanctum and carefully scan the interior walls for a vine-covered section. This wall is easy to miss if you rush, so take your time.

Step 2
Use your Focus abilities to highlight interactable elements, then burn the vines blocking the wall. You can use abilities or fire arrows, though arrows take longer.

Step 3
Once the vines are cleared, look upward to spot the floating cube near the ceiling. This is the first component—the Fusion Reactor Cube.

Step 4
Use Axiom Force to pull the cube toward you and stabilize it. Timing matters here, so maintain control as it moves.

Step 5
Place the cube into the hollow slot in the reactor’s pillar. This will partially restore the mechanism.

2 – Second piece location
Step 1
Use triple jump combined with flight to reach the upper sections near the Sanctum’s main entrance. This part requires precision, so adjust your angle mid-air if needed.

Step 2
Locate a barred room or narrow crevice near the entrance ruins. This is where the second piece is hidden.

Step 3
Inside or near this space, you’ll find a floating Axiom object—the Fusion Reactor Core’s Pillar piece.

Step 4
Use Axiom Force to collect it and store it in your Kuku Pot inventory. This ensures you don’t lose it during traversal.

Step 5
Return to the reactor at the Sanctum’s center.
3 – Activating the Spire of Expiation
Step 1
Identify the pillar slot that is missing its crown. This is where the second piece must go.

Step 2
Position yourself above the slot using flight. This is important because placement requires a top-down alignment.

Step 3
Carefully put the lower reactor piece into position using Axiom Force. If misaligned, adjust your height and angle.

Step 4
Once properly placed, the reactor will activate automatically. You’ll see visual and environmental feedback confirming success.

Rewards for completing the Sanctum of Expiation
| Reward Type | Description |
|---|---|
| Progression | Spire of Expiation completion |
| Exploration Unlock | Access to further Sanctum pathways |
| Experience | Significant XP gain |
| Lore | Environmental storytelling elements |
The Sanctum of Expiation is a great example of how Crimson Desert blends vertical exploration with puzzle-solving. Unlike simpler puzzles, this one forces you to think in three dimensions, especially when placing the pillar piece.
The use of traversal mechanics like flight and triple jump isn’t optional—it’s essential. This design encourages you to fully understand your movement toolkit.
Successfully restoring the reactor feels rewarding because it combines observation, timing, and skill. If you approach it methodically—clearing vines, locating hidden paths, and mastering Axiom placement—you’ll complete it without frustration.
Take your time, use your abilities wisely, and focus on positioning—those are the keys to solving this Sanctum efficiently.
