Fire Emblem Heroes allows you to merge allies to get better heroes. This is a neat mechanism that lets you take your duplicate heroes and put them to good use. And that use is to enhance the existing hero that you might already be using. So in this guide let us check how to Merge Allies in Fire Emblem Heroes, and learn their effects.

How to Merge Allies in Fire Emblem Heroes

Merging Allies in this game is pretty straightforward. You need to have two of the same heroes to merge. Here is its process:

  • Tap on the Allies button.
  • Next, tap on Advanced Growth.
  • Here tap on Merge Allies.
  • Tap on the Lose slot and then the hero you no longer need to place it there.
  • Similarly, tap on the Enhance slot and then the hero you want to improve to move it there.
  • Click on Next.
  • The game will then give you a warning and information about the benefit you get from merging.
  • Once you are sure click on the Confirm button.
  • This will give you a final popup, to confirm you want to merge tap on Inherit. You get these popups because once you merge the two heroes you lose the hero you placed on the Lose slot.

Remember the heroes need to be the same not just their names. So for example you cannot merge Alfonse: Askran Duo with Alfonse: Prince of Askr. But you can merge Alfonse: Prince of Askr with another Alfonse: Prince of Askr. Irrespective of its rarity.
