Lumina in Clair Obscur: Expedition 33 are passive abilities linked to Pictos, which provide various stat boosts and buffs to your party members during battles. These abilities work in the background and help improve your characters' performance without needing to have the corresponding Pictos equipped at all times

How Lumina Works:

• You unlock Lumina abilities by "Mastering" Pictos, which means using a specific Pictos in four battles. Once mastered, the Lumina ability tied to that Pictos becomes available for any character to equip, regardless of whether they have the Pictos equipped

• Luminas are single passive effects without the extra combat stats that Pictos provide, but they can be equipped in multiple slots limited only by the character's available Lumina Points

• Characters start with Lumina Points equal to their level, which are used to equip Lumina abilities. Each Lumina has a point cost, so you must manage these points to optimize your character builds

How to Gain Lumina Points:

• Leveling up characters grants Lumina Points (1 point per level gained)

• You can also increase Lumina Points permanently by using a resource called Colour of Lumina, which can be found as loot, enemy drops, boss rewards, side quest rewards, or purchased from merchants

How to Equip Lumina:

• Access the character menu, select a character, and navigate to the Lumina section.
• Equip unlocked Lumina abilities by spending Lumina Points.
• You can equip multiple Luminas as long as you have enough points and slots available

In summary, Lumina in Expedition 33 are passive boosts unlocked by mastering Pictos and managed through Lumina Points, which enhance your party's overall combat effectiveness by allowing flexible and powerful passive skill customization
