How to Activate Secret Sanctum Puzzles in Crimson Desert

A Crimson Desert guide explains a hidden Sanctum puzzle in which you time Blinding Flash on a blue crystal dial to solve it.

Each completed Sanctum rewards an Abyss Core, a material used in Kuku recipes and related gear upgrades.

There are 16 Sanctums in total, and if you do not have the Kuku Pot, you can buy a Core from Carl.

The guide frames the puzzle as a hidden completion mechanic that unlocks valuable crafting progress in Pywel.
