There are four types of elemental damage: Wind, Water, Earth and Fire. The damage caused by an elemental attack can be increased when cast on a target that is weak to that element or decreased when it is casted on a target that is resistant to it. If an elemental attack is made against a target of that same element the damage can be absorbed and will heal said target.
