('camping' at a save sphere and levelling can be a good idea)

(spend time batteling to level up your characters)

(build up your overdrives in macalania)


Sorry for newbie question, but what does "leveling up" and "building up the Overdrive" mean?

How does one

1)"level up"?

2)"Buildup the Overdrive"?


Is "leveling up" the same as saving at the Sphere?
