Hey, so far I've been enjoying the sphere grid but now I'm a little stuck. I am at the Calmlands at the moment, at about 47hrs. I have just got Auron, Tidus and almost Yuna up to a point where there is a level 3 lock. The only thing is I dont have any L3 key spheres at all yet. I have a lot of level 1 and 2 but haven't used hardly any of these yet, I don't think I have used any L2 ones.

Do I need to go back and find the level 2 locks and unlock those, or wait here till I get a level 3 key?

Thanks for the help. I hope this is the right forum I couldn't see an FF help one. ^^ Apologies if it's not.
