Final Fantasy X Tips

Clear Spheres
Once you unlock Ultima Buster in the Monster Arena, you will be able to buy Clear Spheres there. These can be very useful, because you can delete the weaker stat nodes and replace them with your own by using Strength Spheres, Luck Spheres, etc. The only nodes that cannot be changed are the ones that require an Ability Sphere to activate: White Magic, Black Magic, Skills, and Specials.
