Fixed damage

Fixed damage is a type of damage found throughout the series. It is often an attack that will deal a set amount of damage regardless of what buffs the player may have or what level they are, bypassing everything bar the Invincible status. Fixed damage attacks differ from Fractional damage attacks as it does not depend on the target's HP stat at all, but is somewhat similar to HP to one abilities.
