Reduces your HP to cause Shadow damage to the enemy.
Steiner has Darkside as a Sword Art. It deals Shadow-elemental damage 1.4 times as strong as a normal attack in exchange for 12.5% of Steiner's max HP. Darkside will ignore Mini status if Steiner is afflicted, and also ignores the target's Protect status. It will inflict higher damage if Steiner is equipped with any equipment that increases Shadow damage.
Darkside requires no MP to use and is the only Sword Art at zero MP cost, making it a viable option should Steiner use up his MP with Sword Magic and Sword Art attacks. It is learned with the Blood Sword, which absorbs HP from the enemy making the combination of said sword and Darkside viable early in the game and in Ipsen's Castle.
The formula for Darkside is as follows:
- $ Base = [(Atk Pwr * 14) / 10] - Target's Defence $
- $ Bonus = Str ... [(Lv + Str) / 8] + Str $
- $ Damage = Base * Bonus $
