When not in battle, the player can use the menu screen. On this screen, the player can review each character's status and statistics, use items and abilities, change equipment, save the game (when on the world map or at a save point), and manage orbs called Materia. The main method of customizing characters in "Final Fantasy VII", Materia may be added to equipment to provide characters with new magic spells, monsters to summon, commands, statistical upgrades, and other benefits. Materia levels up with their own experience point system and can be combined to create different effects.
