follow the paths, try not to break any of the 1st,2nd,3rd,4th spheres that require you to get to another location because it leads to different stats. when you finished traveling around your specific spheres than break the 1st spheres 2nd etc. each character has its speacialty ><. unless you know what yoru doing than you should break them XD
for example your using lulu and and you break the lock spheres and you turn out to be a power user so be careful
