Dexterity

Dexterity (Dex) is a statistic in Fire Emblem: Redemption which determines this unit's initial hit rate and critical rate, along with the activation rate of various skills. Specifically, initial hit rate = (Dex*2.5 + Spd*1.5), and critical rate = (Luk*0.5 + Dex*0.25).

Dex can be increased or decreased by various means: the Secret Book and Dexterity Tonic increase the user's Dex by 4 permanently and for the rest of the battle, respectively, and various weapons will increase or decrease Dex depending on various conditions.
