Battle System Guide

Fire Emblem: Three Houses‘ Battle System is all about accomplishing victory conditions required by chapter missions, paralogues, auxiliary battles, and quest battles. In battles, Byleth needs to command his/her students as different units to engage the opposing units and monster enemies. Each unit can lead a battalion and their survival rests in the hands of the player.

Based on the pre-release battle gameplays, the Battle System is divided into two parts.

  • Battle Preparation
  • Battle Phase

Battle Preparation

The player is given an opportunity to check important elements and options before engaging in battle.

Here is a summary of the options:

  • Units – Select which units will join Byleth in battle. There are some battles require a limited number of units. Unused units can be assigned as an accompanying battalion character to an active unit.

Victory and Defeat Conditions differ in each mission, paralogue, or auxiliary battle. Most victory conditions revolve around defeating all opposing units, but there are some that require eliminating enemy commanders or characters such as the bandit leader, Kostas.

When it comes to defeat conditions, the game requires that certain characters, mostly Byleth, Edelgard, Dimitri, Claude, and the Officers Academy faculty members survive. However, there are also battles that require all of your units, including your students, survive the battle.


Viewing the map gives the player the chance to explore and examine the battlefield.

Exploration involves roaming the battlefield with the player’s yellow cursor. This helps the players actually view the terrain and identify its effects. For example, finding a Forest terrain on your battlefield will give an Avoidance and Defense boost to units on it. Moreover, the player can locate treasure chests as well as Lost Spirits if connected online.

Lost Spirits are tiles highlighted with a luminescent purple color. This indicates that another player’s unit has fallen on this specific tile. When the player’s unit reaches and sands on this tile, he/she can obtain weapons that be used or passed on to another unit.
