Hey there! When it comes to materia management in Final Fantasy VII, it’s crucial to have a balanced setup for each character. Make sure to prioritize leveling up your most important materia, such as Magic, Summon, and Support materia. Don’t forget to link compatible materia together for added effects, like pairing Elemental with a defensive materia to absorb or nullify elemental damage. Also, consider the AP growth rate of each materia to maximize your grinding efficiency. Lastly, always customize your materia based on the upcoming mission to have the upper hand in battles. Good luck strategizing!
