Species Conquest arena monsters (+ Greater Sphere for some reason) drop the stat boosting spheres.
Thanks!
This is another question I have. Is there a surefire way to have Yojimbo execute Zanmoto? Or is it just a matter of making the chance as high as possible?
I never really had to use Zanmoto on purpose, since I never tried to defeat the Monster Arena creations.
2/3 times I've called Yojimbo I've gotten it. What I did was just get Yuna's overdrive, summon Yojimbo, and give him like 100,000 Gil, and then he did it. I think you only need to give him 1024 or something though lol. Didn't know that at the time. There's a hidden meter that involves how much he likes you, and the higher that is, the more likely he'll do zanmato. Someone in this thread explained it pretty recently.
