What are the chances of moving each of your characters throughout the whole sphere grid? How hard would it be? I was thinking about it, but then maybe I should just stick to beating the game..

Also.. I want to get the most out of the game.. are there any things I should focus on while I'm not too deep in (in the calm lands right now).. I don't want to miss something..

There's this cave in calm lands actually, but this walkthrough I'm reading told me to save it for later.. any idea what it's for?
