Fire Emblem Heroes started its latest Grand Hero Battle featuring Fire Emblem: The Sacred Stones’ boss character Valter, the third strongest general in Grado’s Imperial Army. The new Grand Hero Battle puts you up against Valter: Dark Moonstone. Clearing it on Hard difficulty gets you a 3-star Valter and clearing on Lunatic or Infernal gets a 4-star version. Again, clearing on Infernal gets you an extra 2,000 Hero Feathers. At 5-star, Valter has Darting Blow 3 and Panic Ploy 3. The Grand Hero Battle: Valter will be available until August 29, 2017. Fire Emblem Heroes is available on iOS and Android.
