how to upgrade weapons expedition 33

To upgrade weapons in Clair Obscur: Expedition 33, follow these steps:

1. Progress in the Story
   You must advance through the main story until you reach the Flying Waters area and complete the related events, including defeating a character called The Curator in the Manor of The Flying Waters. This unlocks the ability to upgrade weapons

2. Set Up Camp on the World Map
   After defeating The Curator and returning to the world map, set up a camp. The Curator will then appear in a cave near the campfire at your camp

3. Interact with The Curator to Upgrade Weapons
   Talk to The Curator at camp and select the "Upgrade Weapons" option. You can then choose which party member's weapon to upgrade and select the weapon to enhance

4. Use Chroma Catalysts as Upgrade Materials
   Weapon upgrades require specific materials called Chroma Catalysts, which come in different rarities for different upgrade levels:

Catalyst Type| Upgrade Level Cap
---|---
Chroma Catalyst| Up to Level 3
Polished Chroma Catalyst| Up to Level 9
Resplendent Chroma Catalyst| Up to Level 19
Grandiose Chroma Catalyst| Up to Level 32
Perfect Chroma Catalyst| Up to Level 33 (max level)

These catalysts can be found as loot, rewards from defeating enemies or bosses, purchased from merchants, or earned from side quests

5. Upgrade Incrementally
   Upgrades are done one level at a time, so to reach higher levels, you will need multiple catalysts of the appropriate type. Upgrading weapons improves their power, attribute boosts, and unlocks bonus abilities at levels 4, 10, and 20

6. Alternative Upgrade Method
   Some enemies or bosses drop upgraded versions of weapons you already own, providing a free upgrade without using catalysts. This is especially useful in the early game

7. Additional Notes
   After Act 2, you can also upgrade weapons by interacting with any Expedition Flag, allowing upgrades outside of camp

In summary, weapon upgrading is tied to story progression to unlock The Curator, requires setting up camp, and using Chroma Catalysts to incrementally improve weapons at camp with The Curator's assistance
