I have read reviews and found that you can get a chronicle 2 sword without beating the Black Knight Pendragon. What you have to do is get a poisonous apple and fish in Muska Lacka in the evening, then if you catch a Mardan Garayan you can purchase a Marden Eins from the fishing log where you exchange your fishing points. The sword costs 2500 fishing points and eventually if you build it up all the way it will become a chronicle 2 sword.
