There are three attack types: Melee, Projectile, and AoE.
Character skills and ultimate moves possessed by characters will correspond to their attack type.
Common Attack Skills obtainable during battle each have a set attack type.
Enemies have attack type resistances, and using an attack type to which they have low resistance increases the damage dealt against them.
Furthermore, Collection Skills, equipment Grade Skills, and Costume Skills may have effects that only apply to characters of a certain attack type.
■Stun
This is a special stat exclusive to Melee characters.
