Chroma is not only the currency required to buy items in Clair Obscur: Expedition 33, but also plays a large role in the story inside the painting. Therefore, it's no surprise that the items required to upgrade weapons in the game are called Chroma Catalyst. In the beginning, players will come across normal Chroma Catalyst, but their names increasingly become fancier as the catalyst becomes better. After the plain Chroma Catalyst, players will get Polished Chroma Catalyst, then Resplendent Chroma Catalyst, before finally reaching Grandiose Chroma Catalyst.

Chroma Catalyst is required to reach level 3 weapon, Polished Chroma Catalyst for level 9, Resplendent Chroma Catalyst for level 19, and finally Grandiose Chroma Catalyst to reach level 32. However, level 32 is not the maximum for a weapon level. Instead, following the theme of Expedition 33, the final level is 33. Since Grandiose Chroma Catalyst can only be used to reach level 32, another item called Perfect Chroma Catalyst is required to unlock the final level. If players are wondering how to get more Perfect Chroma Catalyst in Expedition 33 during their initial playthrough, this guide might help.
