Defense

DEF is short for the status value "Defense" and serves as a means of cutting back damage dealt to the player. It can be increased by means of equiping armor, special equipable items, certain one use items, spells, and (perhaps the most effective way) levelling up through accruing experience points (EXP). Alternatively, the defense stat can be lowered by deequipping items or (depending on the game) status ailments.
