Fractional damage

Fractional 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.
== Appearances ==
=== Final Fantasy II ===
The Blood Sword deals fractional damage, as do HP-draining physical attacks used by enemies. The damage is calculated using the following formula:
:\mbox{Damage} = TargetMaxHP\times\frac{Hits}{16}
The Sap spell also deals fractional damage to the target's MP, which is calculated using the following formula:
:\mbox{Damage} = TargetCurrentMP\times\frac{SpellLevel}{SpellLevel + 1}
=== Final Fantasy III ===
=== Final Fantasy IV ===
==== Final Fantasy IV: The After Years ====
=== Final Fantasy V ===
Gravity, Graviga, Level 4 Graviga, Missile, and Death Claw deal fractional damage.
=== Final Fantasy VI ===
Final Fantasy VI uses fractional damage mainly with abilities that have magical properties. These abilities have a bit flag enabled that redirects the spell power to use a fractional formula:
:\mbox{Damage} = TargetCurrentHP\times\frac{SpellPower}{16}
Most of the fractional damage abilities miss if the target is immune to Death status.
