In this mode, the player is provided a pre-set team of Heroes called Forma. Forma units start at level 1, and grow during battle in a similar manner to mainline Fire Emblem games. However, while all units are capable of leveling up, only the first unit to defeat an enemy will be able to learn a new ability. These range from common inheritable skills to character-unique skills.
