how to get 255 stats??

I have completed the sphere grid with tidus and nearly auron and tidus’ strength is only at 183 and his magic defence is at 221 and there others are around 150 so how do i get more strength and such like so i can max out my stats i am using the expert sphere grid?

There’s a really great guide to maxing out the sphere grid right here (Thread 11098).

I’m going to close this thread, since you can just do that one.
