Another series of quests is now available in Fire Emblem Heroes! Check out the Anima Blessing Quests on the Quests & Missions page.
Like other blessing-related quests, these require you to use Anima Blessed Heroes in combat. Defeat foes and play Aether Raids with these heroes to 5 Orbs and also some other goodies.
The Anima Blessing Quests will be available for about two weeks, ending on 20 April.
