Clair Obscur Expedition 33 How to Upgrade Weapons

Upgrade weapons by spending Chroma Catalysts or acquiring duplicates in Clair Obscur: Expedition 33. See how to upgrade weapons, which weapons to upgrade, and how to unlock this feature here!

How to Upgrade Weapons

There are two ways you can upgrade your weapons in Clair Obscur: Expedition 33:

  1. Spend Chroma Catalysts
  2. Acquire Duplicates

Spend Chroma Catalysts

Catalyst Upgrade Levels
Chroma Catalyst Chroma Catalyst Level 1 → Level 3
Polished Chroma Catalyst Polished Chroma Catalyst Level 3 → Level 9
Resplendent Chroma Catalyst Resplendent Chroma Catalyst Level 9 → Level 19
Grandiose Chroma Catalyst Grandiose Chroma Catalyst Level 19 → Level 32
Perfect Chroma Catalyst Perfect Chroma Catalyst Level 32 → Level 33

Weapons can be upgraded by spending Chroma Catalysts obtained from merchants, as loot, or as drops from enemies and bosses.

Speak to The Curator during Act 1 to upgrade weapons. From Act 2 onwards, weapons can be upgraded by selecting Upgrade Weapons at any Expedition Flag.

Acquire Duplicates

Weapon Dropped by Enemies

Obtaining duplicates of a weapon upgrades its level without using Chroma Catalysts. Duplicates can either be obtained as drops from enemies or bosses, or in New Game Plus.

Which Weapons to Upgrade

The Character's Best Weapon

Medalum Weapon or Last Chance Skill

If you are wondering what weapons you need to upgrade for each character, we recommend upgrading the characters' best weapons per act. This way you will not be wasting the Chroma Catalysts you have gathered!
