Bartz ' s elemental attack is Wind , Lenna ' s is Water , Faris ' s is Fire and Krile ' s is Earth . Galuf is given the innate element of Earth , and therefore his Finisher ability will take this element , although the player will not be able to see this unless they hack the game so Galuf can use this job . Elemental Attack ! will always inflict 9 , 999 damage unless the enemy is immune to or absorbs the element , in the latter case the enemy will get healed for 9 , 999 instead .
