Learn how to cleanse the Sanctum of Temperance in Crimson Desert, how to solve the secret puzzle, and deal with the Antumbra Order forces guarding it.
Where to find Sanctum of Temperance
The Sanctum of Temperance is located east of the Hernan Highlands and south of the Goldleaf Guildhouse, the place where you fought and defeated Kailok, the Hornsplitter.

Important: You will only be able to solve the Sanctum of Temperance puzzle after reaching Chapter 5 and visiting Elowen, the Witch of Wisdom.
Dealing with the Antumbra Order
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
To cleanse the Sanctum, you must find the two missing pieces. If you pay attention to the minimap, you will spot both of them.
To get the first one, stand on the square tile that is in front of the rock structure’s blue crystal.

From that position, head south until you see a hole in the floor. Drop down and locate the fusion reactor core (stone block). You can use Axiom Force to carry it up or seal it in your Kuku Pot.


The Sanctum has a spot on its sides that is missing the reactor. Place it there and use Force Palm.

There is a big building next to the sanctum. The entrance is blocked by vines. Use Brighting Flash to burn them down. The second piece is inside.

This piece must go on top of one of the columns. You can easily spot that it is the one on the left if you view it from the front.
Align it properly and then use Aerial Force Palm. If you did both steps properly, the Sanctum will be back online and a cinematic should trigger.

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 Temperance, you will receive the Kuku Lighting Spear and Kuku Boltsplitter blueprints from Elowen.
The Core of Temperance is the reward for completing the hidden puzzle. This item is used to craft some cool Kuku Pot items.
