Thanks to Hawkeye (FF Legends) for the Sphere Board image.
The sphere board is used to have a character learn a new ability by AP. Each main character have his/her own position on the board, and is moved to each circle on the sphere with the help of Spheres collected from battles, chests, etc. There are different kinds of spheres, such as the magic sphere, the speed sphere, and the ability sphere. The circles on the sphere board designate which sphere could be placed upon the circle; one sphere will be used at each circle. By using the spheres, the characters may learn new abilities, such as black magic, white magic, and other abilities shown in the image above.
