This is how battalions work in Fire Emblem Warriors: Three Hopes
Each unit in Fire Emblem Warriors: Three Hopes can deploy battalions. These units aid the character that uses them in battle, giving them more advantages than if they were operating alone. Each battalion you use will be different, and how it works is vastly different from when it appeared in Three Houses. In this guide we will cover how battalions work in Fire Emblem Warriors: Three Hopes.
How do you use battalions?
A battalion consists of several units that help your characters in battle. Any character in your house can use them, but they provide passive buffs. You can earn them by completing side quests, at survey locations, as mission rewards, or you can buy them directly from your camp’s Battalion Master through the Battalion Guild.
If you review a battalion, you can see how it will help your characters in battle. These units grant and have these characters a distinct advantage over a unit type, allowing them to take less damage against that class.
Each battalion requires a specific rank of authority for a character, highlighted by the letter next to their name. You can increase a character’s authority rank by unlocking classes. For example, the advanced classes have access to a B rank in authority and master classes get an A rank in authority.
Although some classes share the exact requirements for authority rank, it depends on the associated passive and its level. For example, two rank C battalions can both have the passive resist tomes, but if one is level three and the other is level four, the level 4 battalion offers a better passive bonus.
You can exchange battalions before battles. We recommend checking with your camp’s battalion master to see if any new battalions have spawned at the beginning of a chapter.
