How to Solve the Puzzle in the Ancient Ruins in Crimson Desert Reunion
Once you step inside, you’ll enter a small puzzle room with strange wall mechanisms. Before you start solving it, look for the child’s hologram nearby and focus on it. This will unlock a new ability called Focus, which lets you slow down time while regenerating spirit.
Note: You don’t actually need Focus to complete this puzzle.

The puzzle revolves around a set of circular wall plugs that move in and out when struck. Your goal is to press all of them inward.
Here’s how to solve it step by step:
- Start by using your force push ability on the center plug. This will push it inward and cause the nearby plugs to pop out.
- Next, hit the left-side plug to shift the positions of the remaining plugs.
- Finally, strike the right-side plug in a way that ensures none of the others pop back out.

Once all the plugs are aligned correctly, the puzzle is complete, and the path forward will open.

After solving the puzzle, head back outside to where you first entered. You’ll receive the Abyss Crusade as a reward.
