- —Official site's description
A supreme powerhouse revolving around darkness, the Dark Knight's best defense is an overwhelming offense coupled with natural bulk. The realms of demons and darkness are at the fingertips of this class, providing a wide range of attack skills, and the user only grows stronger as they step closer to the doors of death. Swords and katanas are the Dark Knight's weapons of choice, while a decent HP pool and high defensive affinities make them difficult to kill. Skills that cost a percentage of max health to cast confer a higher risk than usual, but once they reach their fullest potential Dark Knights are almost unmatched.
Fitting for a class of shadows, the Dark Knight is appropriately coated in layers of heavy black armor over a black jumpsuit, a full helm covering the entire face, and yellow accents dotting certain armor pieces.
The Dark Knight's Specialty is Adversity. Its Job Command is Dark Arts.
