Resistance

Resistance (Res) is a statistic in Fire Emblem: Redemption which reduces damage taken from enemies using magical weapons; total damage taken is determined by the unit's Res, the enemy's Mag, the enemy's weapon's Mt, and any damage-altering effects caused by skills, terrain or weapon/elemental advantages. Its non-magical equivalent is Def.

Res can be increased or decreased by various means: the Talisman and Resistance Tonic increase the user's Res by 2 permanently and for the rest of the battle, respectively, and various weapons will increase or decrease Def depending on various conditions.
