Essential guide to weapon upgrades in Clair Obscur: Expedition 33, including location, resources, and advanced optimization strategies
Why Weapon Upgrades Are Crucial
Enhancing your arsenal in Clair Obscur: Expedition 33 transforms challenging encounters into manageable battles by significantly increasing your party’s combat effectiveness.
Surviving the game’s increasingly difficult fights requires more than just leveling up characters—weapon enhancements provide substantial damage multipliers that scale with your progression.
As one of 2025’s standout RPG experiences available on Xbox Game Pass, Clair Obscur: Expedition 33 features voice acting by Charlie Cox (Daredevil) and a diverse cast of playable characters.
Each party member possesses unique combat styles that are further amplified through weapon customization, making strategic upgrades essential for maximizing their potential.
Finding the Curator: Your Upgrade Hub
Access weapon enhancements by interacting with the Curator stationed near your campfire. This NPC provides the interface for all equipment improvements once you’ve gathered necessary materials.
Each enhancement tier delivers noticeable improvements to base damage and stat scaling percentages, ensuring your weapons grow more lethal as character levels increase.
However, this vital NPC only becomes available after completing The Flying Waters zone and encountering him personally at The Manor location.
Following your victory over the boss Goblu and returning to base camp, the Curator remains permanently accessible for the remainder of your adventure.

Chroma Catalysts: Your Essential Resource
All weapon improvements demand Chroma Catalyst resources, with their required quality escalating alongside your equipment’s current enhancement level.
These vital materials primarily drop from defeated adversaries and boss encounters throughout your journey across the game world.
Exploration rewards diligent players with additional Catalysts hidden off main pathways, while side missions often provide them as completion bonuses.
When supplies diminish, Gestral Merchants stock basic Catalysts, though currency is better spent on rarer consumables unavailable through regular gameplay.
Standard Chroma Catalysts discovered in the environment can be refined into superior versions via the Curator’s “Upgrade Expedition resources” function.
Advanced Upgrade Strategies
Prioritize upgrades for your main damage dealers first, as their enhanced output will help farm Catalysts more efficiently for supporting characters.
Common mistake: Attempting to evenly upgrade all party weapons early game spreads resources too thin. Focus on 2-3 core weapons initially.
Before advancing story zones, thoroughly explore completed areas for hidden Catalysts—many are missable if you progress too quickly.
Advanced tip: Regular Catalysts upgrade to higher rarities at a 3:1 ratio. Hoard them until you can mass-upgrade rather than using them individually.
Check weapon scaling letters before upgrading—some weapons benefit more from enhancements due to superior scaling coefficients.
