In brief

Aeserion Scales are rare materials essential for pushing your weapons and armor to their maximum in Crimson Desert. They can be gathered at the Serpent Sanctuary without necessarily fighting the boss Aeserion itself, and they are used both for final upgrades and for Kuku Pot recipes at Grimnir's.

Crimson Desert confronts us with all sorts of challenges, including the perpetual quest for gear upgrades. The Aeserion Scales, which interest us today, are needed to perform the final upgrades of weapons and armor. This article looks at how to obtain these scales, and the most effective ways to use them.

What are Aeserion Scales?

Aeserion Scales are rare and powerful materials, essential for upgrading your gear to its maximum level. Sought after by adventurers seeking defense and attack power, these scales are tied to a unique boss, Aeserion, found in a secret area called the Serpent Sanctuary.

The Serpent Sanctuary is located to the south on the map, in the Dewhaven region, on the coast of Deleysia. It is a place shrouded in mystery where you can encounter the great serpent Aeserion.

Note

A boss fight can occur, but you can still collect the scales without having to fight the serpent!

Accessing the Sanctuary and Collecting the Scales

Access to the Serpent Sanctuary is easy, you just need to head to the southern coast of Dewhaven. Once there, exploring the area is doable without being too harassed by the serpent's attacks. The lightning bolts that strike the ground are relatively harmless while collecting the serpent's scales.

Aeserion Scales are collected using the Axiom Force skill (L3), but the essential prerequisite for collecting them remains the Kuku Pot as the collection tool that seals the contents.

Tip

While collecting, don't forget to watch out for Aeserion's attacks!

Uses for Aeserion Scales

Aeserion Scales are useful for the final upgrades of your weapons and armor: each upgrade gives you a boost in attack and defense. It's up to you to decide whether you want to upgrade this or that piece with a specific build in mind.

Aeserion Scales are also used to craft certain Kuku Pot recipes available from Grimnir in the town of Hernand. These recipes allow you to produce powerful items, which could help you get out of a tricky fight.
