Learn how to cleanse the Sanctum of Oblation in Crimson Desert, how to solve the secret puzzle, and deal with the Antumbra Order forces guarding it.
Where to find the Sanctum of Devotion
You can find the Sanctum of Oblation on the far east side of Delesyia, fairly close to Marni’s Laboratorium.
Important: You will only be able to solve the Sanctum of Oblation puzzle after meeting Lyselia, the Witch of Humility.
The Sanctum is part of The Witch of Humility questline, which includes three more Sanctums you need to find and cleanse:
- Sanctum of Devotion
- Sanctum of Veneration
- Sanctum of Oblation (this one)
- Sanctum of Faith
Dealing with the Antumbra Order
You have to liberate the Sanctum first. Each Sanctum is guarded by forces of the Antumbra Order. The Antumbra Order is a group of religious zealots who believe that darkness can bring true balance to Pywel. Their way of worshipping is by offering human sacrifices.
Most of the enemies in the Sanctums fight with traditional melee weapons. However, a few of them fly and cast shadows that deal considerable damage. Having to deal with them while being overrun by the sword and axe wielders is not fun, but luckily for you, there is an easy way to get rid of them.
To kill these flying enemies, simply use Blinding Flash to reflect the light against them. There is no death animation; they just disappear.
Arrows or Aerial Force Palm can work as well, but I don’t recommend this slower and less efficient method because the NPCs are very fast.
How to Cleanse the Sanctum of Oblation
Use the main structure of the sanctum as the starting point and head downstairs, then walk to the right side, where you’ll find an entrance to the lower level of the ruins.
You will see a locked room on the left side. It’s impossible to open it here. Continue up the stairs on the right side until you find a hall with many spider webs.
The reaction core you are looking for is located in a room at the end of the hall. Don’t leave the room after sealing it on your Kuku Pot.
Light the brazier that’s next to the broken wall. This will open the locked room you previously saw. Inside it, there’s a treasure chest that contains Red Needle.
Now all you have to do is place the reaction core on the right column to cleanse the Sanctum.
Second (Secret) Puzzle
There is a hidden puzzle in this Sanctum. See the blue crystal at the front of the Sanctum? You have to use the Blinding Flash to redirect light directly into it. The circle with the little gems will start to rotate.
Make sure to focus the light only when a gem is passing through the circle at the top. A metallic sound will trigger when you do it correctly. I’d describe it as something metallic being hit with a sword.
Try to get used to the timing. That will make it easier for you. The piece that comes out of the Sanctum is the actual reward, not another part of the puzzle. Seal it away on your Kuku Pot.
If you have a custom keybind for Blinding Flash on a single button, this may prevent you from completing this puzzle and timing here is key.
Rewards
As a reward for cleansing the Sanctum of Oblation, you will receive the Kuku Insect Gatherer’s Pack and Kuku Breeze-Step Boots blueprint.
The Core of Oblation is the reward for completing the hidden puzzle. This item is used to craft some cool Kuku Pot items.
