A detailed guide to solving the Sanctuary of Revelation puzzle from the witch Alesil: the location of the sanctuary on the map, the solution principle, finding the Cubic Reactor Core and the support fragment.
Location : Demeniss, Snake Swamp.
Approach the shrine from the south. Defeat enemies until the meter on the left reaches 0. Once this happens, the shrine will be liberated. Note that the Staff of Antumbra also resides here—another powerful boss who uses magical attacks that must be dodged ( magic cannot be blocked). Wait for normal attacks and parry them to perform counterattacks.

Once all the smaller enemies have been defeated, head to the misty part of the shrine, where you’ll face the Spear of Antumbra. This boss uses magical attacks that must be dodged. Blocking them is impossible. Dodge the magical attacks, parry the normal ones, and use powerful counterattacks to fill the stun meter beneath the enemy’s health bar. Once defeated, the shrine will be liberated.
Note : If you move a few meters away from the shrine, previously placed items will return to their original positions. However, if these items have already been in Yellowbeak’s cauldron, and you retrieved and placed them from there, they will be placed back in the cauldron. We also have a detailed guide covering all the Shrines in Crimson Desert .
After freeing yourself, you’ll find yourself in the courtyard where you fought the boss. Head west and find a detached building just beyond the ruins. Climb it and look for cracks in the roof. Run across them to cause the roof to collapse, then drop inside to find a column fragment.

Take it and return to the reactor. Find the broken pillar in the western corner of the reactor, place the fragment above it, and rotate it until green leaves appear. Then use the “Palmara Strike” (Power Palm) either by carrying it or from the air. In the latter case, you’ll need to jump onto the floating fragment above the pillar, jump, and press the mouse wheel . “Palmara Strike: Carry” requires a separate unlock in the green branch of the skill tree.
Standing near the reactor, look east so that the device itself is behind you. You should see the reactor core hovering on the ledge above.

Take it and find the square hole in the device on the north side. Align the block with the hole until you see green leaves, then use Palmara Strike (Power Palm). Simply approach it and click the mouse wheel, or use Palmara Strike: Transfer if you’ve unlocked the skill in the green skill tree. In this case, you don’t need to detach the Axiom Powers: hold the part and click the wheel when green leaves appear.
Once both the core and the pillar piece are in place, the shrine will become operational. The witch Aresil will appear, and the quest will be complete. You’ll unlock several new recipes in Kilnden’s workshop with Grimnir. If the witch doesn’t appear automatically, move closer to the illuminated square area near the reactor.
