A few things.

-On the first page of this thread Palazzo posted where to find celestial weapons, and that's all good. But where are these 'celestial mirrors' and things we need to obtain the weapons?

-Where can I get some Level Four key spheres?

-On the airship, there's the option to put in passcodes in to access other areas. Now.. I'm absolutely dumb as shit when it comes to riddles, so could anybody give me a couple? Also, one that does confuse me quite a lot is "Right Sixteen, Right Four" in the Calm Lands. Halp?
