GC: What items can only be found online?

[skylimit0]

Playing a game that says "Online" when you can only paly offline is a pain in the *&*^^&^*&*&%%$^^%. Does anyone know what items can only be found online so I don't rise my hopes of recieving weapons like the double saber.

Double Saber can be found offline. I have gotten tons of them. The only things I can think of are online quests...
