Crimson Desert: How to Solve Blue Thicket Ruins Puzzle Fast

The Blue Thicket Ancient Ruins puzzle in Crimson Desert looks like a logic riddle, so most people waste time hunting for a hidden lever, a symbol code, or an enemy to kill. There is none of that. This is a short environmental interaction: you hit two wall segments with the right ability in the right order, then let the mechanism finish. The whole thing takes under a minute once you know the inputs.

The short version

• Location: Blue Thicket region of eastern Delesyia, northeast of Mount Benus.
• Ability you need: Nature’s Grasp — PS5 Triangle + Circle, Xbox Y + B, PC F + Left Click.
• Order: right wall first, then the left wall, facing inward toward the central mechanism.
• Confirmation: the internal mechanism advances and the blue energy lines light up.
• Reward: an Abyss Artifact plus a fast-travel teleport point.

Where to find the Blue Thicket Ruins

The ruins sit in the Blue Thicket region of eastern Delesyia, northeast of Mount Benus. If your map or subtitles spell the region differently — Delazia, Delezia, Delicia — those are mis-transcriptions; the canonical spelling is Delesyia. Use Mount Benus as your anchor and head northeast into the Blue Thicket; the puzzle site is an Ancient Ruins structure, not a combat arena or a locked dungeon.

You are looking for a ruin with two usable wall sections flanking a central mechanism. If you reach a ruin packed with enemies, locked doors, or collectibles, you are at a different site. The Blue Thicket solution lives entirely on those two walls.

Exact puzzle solution, step by step

Step 1: Activate the right wall

Stand at the entrance facing inward toward the central mechanism so “right” and “left” are read from that viewpoint. Move to the wall segment on your right and use Nature’s Grasp (PS5 Triangle + Circle, Xbox Y + B, PC F + Left Click) when the prompt appears. That energizes the right node. The order is not cosmetic — you start on the right and work to the left.

If nothing fires, you are probably aimed at decorative stone. Ancient Ruins geometry makes plenty of surfaces look interactable that are not. Reposition until the Nature’s Grasp prompt actually shows, then activate.

Step 2: Activate the left wall

With the right node live, cross to the matching wall on the left and use Nature’s Grasp again. The two walls are a paired set — there is no third input. This is where players overthink it and start sweeping the ruin for switches; ignore that urge until both walls are confirmed.

Step 3: Let the mechanism finish

Once both walls register, the ruin’s internal mechanism advances and routes power through the structure. Wait for it. The visible completion signal is the blue energy lines illuminating across the ruin — that is the game telling you the circuit closed. Do not reset the moment the walls settle; resetting mid-transition is the single most common reason the puzzle “won’t finish.”

What you get for clearing it

Completion grants an Abyss Artifact and activates a fast-travel teleport point at the ruins. The artifact feeds the wider Abyss Restoration loop, so this is worth clearing even on a quick pass. If you are working through the whole set, our Abyss Challenges and Axiom Force guide covers the manipulation mechanics most of these ruins share.

Common mistakes

• Treating it as a logic puzzle. There is no symbol code or hidden combination here — just two walls.
• Using the wrong ability. The required input is Nature’s Grasp; normal attacks and movement do nothing.
• Aiming at decorative stone. Wait for the prompt before committing — the prompt, not the wall’s look, tells you it is interactable.
• Doing the walls out of order. Right wall first, then left, while facing inward.
• Resetting too early. Let the mechanism move and watch for the blue lines before assuming it failed.

If you are clearing ruins back to back, the Grey Forest Ruins dial puzzle nearby uses a different input pattern, so don’t carry the Blue Thicket muscle memory into it.

Practical takeaway

Head northeast from Mount Benus into the Blue Thicket, face the central mechanism, hit the right wall then the left with Nature’s Grasp, and wait for the blue energy lines to confirm the circuit. You walk away with an Abyss Artifact and a new fast-travel point — under a minute of work once you stop treating it like a riddle.
