Fire Emblem Heroes released over four months ago, but the mobile game keeps getting content. The latest event introduces Legion, a boss character from Fire Emblem: New Mystery of the Emblem. Just like all the other Grand Hero events, you’ll unlock a four-star version of the character if you manage to beat the level on hard or lunatic mode. This is a great way to expand your roster of fighters, Legion being one of the more obscure characters added to the popular mobile game. The event begins on June 16th, so get ready for a great battle.
