Final Fantasy IV has 8 different enemy types, which affect how certain weapons deal extra damage towards enemies of particular types, or how the enemies deal less damage towards characters equipped with certain armor. Specifically, damage is either multiplied by four, or quartered, respectively. In the case of the undead enemy type, several other flags are added.
