This is a guide to Luck, one of the stats of Fire Emblem: Three Houses. Here we will explain how this stat works, how it affects your units, and how you can use it to optimize your army.

What Does Luck Do?

Luck is one of the eight main stats. It plays a role in upping the critical hit rate gained in battles. You can determine a unit's critical hit rate by looking at the 'Crit' stat displayed when selecting a unit to attack.

As you can see, the same character attacking the same unit has a higher crit after using a Goddess Icon to add +4 Luck.

How to Increase Luck

You can increase Luck of some units by levelling up, using items, or equipping abilities.

Leveling Up

Whenever a character levels up, some of their stat increase. However, this is cannot be controlled, and you cannot choose to make them increase this skill, unlike the other two options.

Items

You can equip a Goddess Ring to increase a character's luck, or use a Goddess Icon or Miracle Bean to permanently increase their luck.

Equipping Abilities

Certain Abilities increase a character's Luck when equipped. For example, a House Leader's Pomp and Circumstance ability adds +5 Luck and Charm when equipped. To learn how to equip abilities, don't forget to check out our page on How To Learn and Equip Abilities!

Rally Skills

When some units level up their Authority skill, they gain the ability to rally other units, boosting their stats temporarily. Luck is one of the possible boosts provided by Rally.

How to Use Luck

Units with High Dexterity/Critical Chance

Luck stacks with Dexterity to increase a unit's crit rate. While it isn't recommended to focus on it solely for the crit rate because Dexterity does the same thing while increasing hit chance as well, if you have spare Luck items, you can use them to further improve high Dexterity character's crit rate.

Hard/Maddening Difficulties

On normal difficulty, enemies do not land critical hits on you. On higher difficulties, they enemies can possibly kill your units instantly if they land a critical. This makes luck all the more valuable in higher difficulties, especially in Classic Mode when units don't come back.
