Achievement Guide
A clean Clair Obscur achievement run is mostly about planning before the late-game cleanup. Track optional scenes, collectibles, combat challenges, and character progression so the final stretch does not become guesswork.
For a 100 percent route, finish the story naturally while recording optional scenes, side areas, bosses, journals, music records, and character-specific combat tasks. Do not rush into a final cleanup without a written checklist.
Early unlocks such as breaking enemies, upgrading weapons, using Lumina points, and witnessing optional camp scenes are simple if you engage with each system. The harder part is remembering optional content that does not sit on the main route.
Leave boss perfection attempts and collectible sweeps until you understand the combat rhythm. A stronger party makes no-damage attempts and late optional fights less frustrating, while your notes prevent random backtracking.
