Defence

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

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