Earth Shake

Earth Shake is a Blue Magic spell exclusive to Final Fantasy IX that can be used by Quina. It is learned by having Quina Eat a Adamantoise, Shell Dragon, or Earth Guardian. It inflicts heavy Earth elemental damage to all enemies, and misses against flying or Floating opponents. The spell is useful in the fact that it is one of the very few Earth elemental attacks the party has access to. It costs 20 MP to cast.
