Gray Waves

Gray Wavesis a refreshing Assist skill introduced in Fire Emblem Heroes, where it functions as an evolved version of Sing. While Gray Waves retains the normal ability to grant an additional action to the selected ally; it also grants an extra space of movement to flier or infantry allies.

Future Vision is exclusive to Azura (Vallite Songstress), and cannot be inherited.
