Luck

Luck (Luk) is a statistic in Fire Emblem: Redemption which determines this unit's avoid rate, critical rate and protection rate, along with the activation rate of various skills. Specifically, avoid rate = (Spd*0.75 + Luk*0.25), critical rate = (Luk*0.5 + Dex*0.25), and protection rate simply equals Luk.

Luk can be increased or decreased by various means: the Goddess Icon and Luck Tonic increase the user's Luk by 4 permanently and for the rest of the battle, respectively, and various weapons will increase or decrease Luk depending on various conditions.
