The basic information of a card includes name, level, HP, Power, energy cost, star-level and College.
The quality of a card depends on its star-level. The highest star-level is currently 6, as while there is talk of 7 star cards, none have been released on the English servers, while the lowest star-level is 1.
The higher the star-level, the higher the quality, base stats and level cap. A card’s HP and Power can be augmented when the card’s level goes up or limits is broken. Cards can exceed its max level with a Limit Break Sirius.
