Aymr was crafted using the same technology as the Heroes' Relics, and made specifically to be wielded by Edelgard von Hresvelg. It boasts the highest Might among all Heroes' Relics in the game, and bearers of any Crest of Seiros can use the Combat Art Raging Storm. With it, a unit can move again after defeating an enemy, for as many times until Aymr's durability runs out.
Aymr is still present in Fire Emblem Warriors: Three Hopes, but has been replaced by Labraunda as Edelgard's axe of choice. It is an S-rank reward on Edelgard's route, serving as a powerful bonus weapon for her.
