Costume Evolution becomes available at level 100 and can be accessed via [Character Portrait] > [Costume] > [Costume Evolution] in the top left corner of the game.
Costume Evolution can be applied on weapons and armors and at least 1 Costume in each slot must be activated first.
When evolving a Costume, the default option of the Costume set increases and an exclusive Costume Evolution option is added.
Costume Evolution is split into 3 tiers [God·Extreme·True] and Costume Evolution's exclusive and default options increase with each tier. When achieving [True] level when evolving a Costume, a special border effect will be added to the name of the costume.
Evolving a Costume consumes Costume Evolution Cores.
