Should I Merge or Fodder Off My Units?

This is a comprehensive list of heroes in Fire Emblem Heroes (FEH) classified into Merge or Fodder. If you are wondering whether to merge up a certain hero or fodder them off for Skill Inheritance, read on!

Should you merge or fodder?

Regardless of our advice below, we highly suggest you save excess copies of heroes as combat manuals.

Try to keep at least one copy of each hero, unless you're positive that you won't be using them often. Certain game modes like Limited Hero Battles and Resonant Battles require units from specific game titles. Having a diverse barracks allows you to complete these game modes.

If you feel that you will use a certain hero in multiple game modes, or if they are your among your favorites, we suggest merging the hero. Merges increase the unit's stats, remove their bane, and increase their score in Arena.

We also suggest keeping at least one hero of each unit archetype, such as Bow Flier, Axe Cavalry, etc. This way, you'll have a versatile barracks that can deal with most situations.

For heroes that are unused in multiple game modes, we suggest using them for Skill Inheritance to improve your favorites.
