Dark knight job command. Cursed sword techniques cut down the foe.


Darkness (暗黒, Ankoku?) is the action ability of the Dark Knight job in Final Fantasy Tactics. It includes draining abilities as well as powerful damaging attacks based on the user's HP. Darkness abilities require an equipped sword to be performed.

Dark Knight job is usable by the player in the The War of the Lions version. In the original PlayStation version, "Dark Knight" was Gaffgarion's exclusive job. His job has since been renamed to Fell Knight. While his two abilities, Shadowblade and Duskblade, appear identical to Sanguine Sword and Infernal Strike, Gaffgarion's variants are slightly more powerful.
