Fractional damage (割合ダメージ, Wariai Damēji?, lit. Percentage Damage) is a recurring damage type in the Final Fantasy series. These abilities often deal damage based on the victims' current or maximum HP. Very often, these types of attacks have no effect against bosses. The most famous fractional damage ability is the recurring Gravity spell.
