Overview
Aeserion's Scales are the final and most important refinement material in Crimson Desert. They are required to upgrade weapons and armor to the maximum refinement level. Without these scales, gear cannot reach its full potential, and the stat boost provided by the final refinement tier is the largest single-level increase in the entire upgrade system. Where most earlier refinement levels provide roughly three points of improvement, the final level grants approximately five points, making it a significant jump in overall power.
Aeserion's Scales are found exclusively at the Serpent Shrine, a secret location on an island in the southwestern tip of Delesyia. They are collected using Axiom Force and must be sealed into the Kuku Iron Pot for storage. In addition to the scales, the refinement to maximum level also requires an Abyss Artifact.
Aeserion's Scale is the final refinement material in Crimson Desert, required to upgrade weapons and armor from level 9 to level 10 via gear refinement. This last upgrade grants 5 stat points, a significant jump compared to the roughly 3 points gained at each previous level. Scales are collected exclusively at the Serpent Shrine in Delesyia and cannot be purchased from any vendor.
The in-game description reads: "A steel scale obtained from Aeserion, the Great Serpent. An unknown power still surges within it."
How to Obtain
To collect Aeserion's Scales, travel to the Serpent Shrine in the Dewhaven Territory, located on the far southern coast of Delesyia. The scales appear as pentagon-shaped icons on the minimap once you enter the shrine area. A single visit typically yields around 50 scales, and there are plenty scattered throughout the shrine, so running out is rarely a concern.
Collection Requirements
Axiom Force: You must have Axiom unlocked. When near a scale, activate your Axiom Force grapple (hold L3 on controller) to target it.
Kuku Seal: After grappling a scale, press Y (Xbox) or Triangle (PlayStation) to seal it into your Kuku Iron Pot. The Kuku Seal ability becomes available after completing Chapter 3.
No boss fight required: You do not need to defeat any boss or complete any quest to collect scales. They can be gathered freely during your first visit to the shrine, even while the great serpent roams the area.
Storage in the Kuku Iron Pot
Once sealed, Aeserion's Scales are stored inside your Kuku Iron Pot. They do not appear in your regular inventory automatically. To use them for refinement at a blacksmith, you must first open the Kuku Iron Pot from your inventory and withdraw the number of scales you need. This is an important step that many players overlook: if you go directly to the blacksmith without withdrawing scales first, the upgrade option will not appear.
Aeserion's Scales do not stack in your regular inventory. Each scale takes up one individual inventory slot, so withdraw only the number you need for a specific upgrade. After completing the refinement, deposit any remaining scales back into the Kuku Iron Pot to keep your inventory clean. The Kuku Iron Pot holds up to 240 items, and you are unlikely to exceed that limit with scales alone.
Usage
Aeserion's Scales are used at the blacksmith to perform the final refinement level on any piece of gear. This is the culmination of the gear refinement system. The final upgrade is the most powerful single-level boost in the game, providing roughly five stat points compared to the two or three points of earlier levels.

Aeserion's Scales serve two primary purposes:
Level 10 Gear Refinement: Bring scales to any blacksmith to upgrade your weapons and armor to the maximum refinement level. Each piece of gear requires a set number of scales alongside other materials.
Aeserion Weapon Crafting: Scales are also required as a crafting component for weapons unlocked by the Aeserion's Gear Blueprint, including the Aeserion Sword, Mace, Greataxe, and seven other unique weapons.
Serpent Shrine Exploration
If you have already collected all the scales visible in the Serpent Shrine during your first visit, the location offers a repeatable exploration activity called the Serpent Shrine Exploration. This costs a small amount of resources to activate but provides additional Aeserion's Scales without requiring you to physically revisit the shrine. In most cases, the initial collection from the shrine provides more than enough scales to fully upgrade all of your gear, but the exploration option is useful for players who want extras or who upgraded additional equipment later.
Canonical Farm Route
The fastest scale farm in the game is a single loop around the Serpent Shrine itself. The shrine's own fast-travel point is the only anchor you need; one careful pass through the area returns roughly fifty scales, and the route resets after a short interval so you can repeat it as often as you want for refinement stock.
Fast travel to the Serpent Shrine. The shrine point sits on the small island in the southwest of Delesyia. If you have not unlocked it yet, approach the island from the mainland coast and trigger the fast-travel marker before starting the farm; you will rely on this anchor for every reset.
Cross the soldier camp from above. From the fast-travel marker, head toward the cliff edge. Imperial soldiers are positioned along the shore firing at the serpent. They are aggressive and will engage you on sight if you walk through their camp. Jump from the cliff and glide past them rather than fighting through, which keeps you out of combat and saves the route's time budget.
Land near the serpent itself. The serpent does not retaliate while you scout its body and the surrounding rocks, so you can pick scales freely as long as the soldiers do not pull you back into combat. The scales appear as pentagon-shaped glints scattered across the ground, ledges, and the serpent's body.
Pick scales with Axiom Force. Aim each scale and use Axiom Force to draw it in; the standard interact button will not collect them. Sweeping the full ground level plus the upper terraces in one pass typically nets around fifty scales before the visible spawns thin out.
Reset by fast travel. When the visible scales run out, open the map and fast-travel back to the same shrine point. The scale spawns repopulate, the soldiers return to their patrols, and the loop is ready to run again.
Per-Pass Yield
Source | Approx. Yield | Notes |
|---|---|---|
Ground spawns near the serpent | ~50 scales per pass | Ground and lower terraces; cleared first. |
Upper-cliff and ledge spawns | Included in the ~50 total | Easy to miss on the first lap; sweep the elevated areas before resetting. |
Soldier drops | None | Soldiers are obstacles, not loot sources; avoid combat to keep the pass clean. |
Threat Assessment
The serpent in the middle of the area is not the threat on this route. It tolerates the player walking its body and picking scales without aggroing. The aggressive group are the imperial soldiers firing on it from the surrounding cliffs and shoreline; they are armored and ranged and will quickly chew through your stamina if you try to bulldoze through them. Glide past them on the way in, stay below their sight lines while you collect, and fast-travel out the moment the area is empty rather than walking back up through the camp.
Linked Resources
The same shrine point also hides the Aeserion's Gear Blueprint recipe book, which is what makes Aeserion's Scales useful in the first place. If you have not collected the blueprint yet, do so on the same trip: glide past the soldiers, look for the rock barrier on the far side of the area, and break it with focused force-palm. While inside, read every page on both the left and right halves of the book; missing a page locks part of the Aeserion crafting list and leaves your scale stockpile with nothing to spend on.
Tips
Prioritize upgrading your main weapon first. The attack power increase from the final refinement level has the largest impact on overall combat effectiveness.
Withdraw scales from the Kuku Iron Pot before visiting the blacksmith. The refinement menu will not show the final upgrade as available if the scales are still inside the pot.
Since scales do not stack, avoid carrying too many at once. Deposit extras back into the Kuku Iron Pot after each upgrade session.
You can visit the Serpent Shrine at any time after reaching Delesyia. There is no level gate or quest prerequisite for entering the area and collecting scales.
Completing the Shackled God quest line clears the shrine of active hazards, making subsequent collection trips safer and faster.
The Serpent Shrine is accessible as a farming location even before completing the Shackled God quest line. You can freely collect scales without fighting any bosses.
Remember that scales do not stack in the Kuku Iron Pot. Plan your trips accordingly, as the 240-scale cap means you may need multiple visits for a full gear set.
Always withdraw scales from the pot before visiting the blacksmith. This is a common oversight that wastes a trip.
The level 10 refinement bonus of 5 stat points is nearly double the bonus from previous levels, making it one of the most impactful upgrades in the endgame.

How to Collect
Aeserion's Scales are found scattered throughout the Serpent Shrine and appear as pentagon-shaped icons on the minimap. They look like iridescent blue shards glowing on the ground or stuck to the ancient stone pillars of the shrine. To collect them, you need two things: Axiom Force and a Kuku Iron Pot (obtained via the Kuku Seal, which unlocks in Chapter 3).
Collection Steps
Travel to the Serpent Shrine in the Dewhaven Territory of Delesyia.
Activate Axiom Force (L3 on PlayStation, LS on Xbox).
Aim at a glowing scale and pull it toward you.
Press Y (Xbox) or Triangle (PlayStation) to seal the scale into your Kuku Iron Pot.
Repeat until you have collected all available scales in the area.
Each visit to the shrine yields approximately 50 scales. Scales are stored individually in the Kuku Iron Pot and do not stack, with a maximum capacity of 240 scales per pot.
Withdrawing Scales
Before visiting a blacksmith to refine your gear, you must withdraw the scales from your Kuku Iron Pot into your regular inventory. The blacksmith cannot access scales stored in the pot directly. Open your Kuku Iron Pot and manually transfer the required number of scales before starting the refinement process.
Alternative Collection Method
If you prefer a passive approach, you can send your Greymane companions to farm scales on your behalf. Return to your camp, speak with Ross, and select the Delesyia: Serpent Shrine Exploration option. At least one Greymane in your party must have the Explorer skill for this option to appear. This method costs resources but allows you to collect scales without visiting the shrine yourself.
