Luck

Luck (Japanese: 幸運 good luck), abbreviated Lck from Path of Radiance onward and Luk in Genealogy of the Holy War and Thracia 776, is a character stat from all games in the Fire Emblem series. It determines the unit's hit percentage on an enemy, and also decreases the enemy unit's critical hit chance. Some items and weapons can increase the luck rate by a certain amount of points.

In Tokyo Mirage Sessions ♯FE, luck functions differently than other stats. Instead of being a stat that increases during level ups, it is a stat that has five levels: Poor, Weak, Norm, Good, and High. This can be increased or decreased depending on circumstances. For example, a character's luck may be raised if a drink is purchased from a vending machine.
