More information has been released via the official website detailing the Dragalia Lost Fire Emblem Heroes crossover that will begin on April 25, 2019 and end on May 14, 2019. When i appears, it will bring Defensive Battles, which sound a bit strategic, and give everyone a chance to make a five-star Alfonse their friend.
The free Alfonse will be the first five-star Adventurer to be given away in the game. (Previous Adventurers given away through events have been four-star characters.) He is a sword user and light element unit. Information about his skills hasn’t been released yet. However, we do know that he will be earned in the same way as a Raid unit. You initially get him temporarily. Adding him to your party and completing quests with him will increase your friendship. Once that is maxed out, he joins you for good.
The Dragalia Lost Fire Emblem Heroes Defensive Battles almost appear to be Musou-like in nature. People work cooperatively on a map to defeat Imperial forces. There are gates and homes to protect from hordes of enemy armies, as well as an enemy commander in the field. You have to either protect the gate from all enemies or take out the leader to win. On the map, you can see where the other three players and where the enemy units are located.
Dragalia Lost is available for Android and Apple iOS devices. Information about a Fire Emblem Heroes Summon Showcase has not yet been revealed.
