Fire IV is a tier IV Black Magic spell that deals Fire-based elemental damage to a single target. Scholars are also able to use this spell while under the effects of Addendum: Black or Enlightenment. It generally is used as the main damage output on enemies weak to fire damage and then followed by weaving Fire III into the damage rotation during recast periods. Its damage output can be increased when used in conjunction with the Black Mage's Freeze spell or the Red Mage's Enblizzard II enhanced physical attacks, which lower the enemy's resistance to fire-elemental damage.
It is also an avatar ability used by Ifrit learned at level 60. It deals Fire-based magic damage to a single target for 118 MP.
