Special Practice

Special Practice is the only way to Idolize a card. You just need to "fuse" two exact copies of an non-idolized card and pay the cost. An idolized card will have a new art, increased stats, increased level cap, and bond points. You can unlock the side stories of idolized members after maxing out their Bond Points.

Take note that only the level and bond points of the first card will be carried over after the Special Practice and the second card will be lost. You must always select the higher lever card as your first card when idolizing.
