Oh but in addition to my last post... There are actually two battles which I don't mind using zanmato against and thats Earth Eater and Greater Sphere as long as I win the first battle legitly since farming Luck Spheres is seriously lenghty thing to do and so using Zanmato everyonce in a while when I get the money to speed up the process a little bit doesn't hurt that much not to mention I can rebattle them anytime anyway.
