There's two separate save spheres you have to go to for victorious and murasame. So it's one at a time

There's another thing in the area called Sanubia Sands. I can't remember what it is thoughX.x then there's one on that big thing in mi'ihen. and for some reason I'm thinking there's a third at besaid, but I didn't find it on the map, so I'd have to look it up first^_^
