You have my interest. A question though, how broken can sword skills become? We talking Vergil or Sephiroth levels of OP? Or a little less?

Depending on the class, the master sword skills could have you fighting like both mixed in one. Fighting like Virgil would be close to a class called Asura.  And fighting like Sephy would be a sword class called Harbinger. I plan on the demon king being nothing to snuff at so the skills will be pretty OP. Like "destroying a city in an instant" OP.
