I'm coming up to Mount Gagazet, and I need to get a whole bunch of Lv. 3 Key Spheres, and I hear Biran and Yenke are good sources, as long as Kimahri can use Steal. So how can I get him over to Rikku's sphere grid really quick? I have some weird things like "Friend Sphere, Blk Magic Sphere" and such, I just don't understand how they work. ;S
