From what i know and heard Knight is a end game char i never really used it but this is what i know. What you do is at end game you will use 2handed sword(Genocide) and either go for 1 hand sword and shield or dual sword for total damage pvp.Imma try to make out a guide of skills and see how it goes.But this is possibly the closest i can get feel free to comment on it.
