- Support Cards have three grades: Uncommon, Rare, and Epic.
- Higher-grade cards are more difficult to obtain but grant increased effects when equipped.
- Each Support Card is assigned to a specific character category.
- Support Cards that belong to the same character category as the character cannot be equipped on the character.
- You cannot equip more than one Support Card with the same character category.
- Support Cards consist of 1 main option and 4 sub-options.
- The options are inherently set for each type of card.
