Hey there! When it comes to materia management in Final Fantasy VII, it’s crucial to prioritize which ones to level up. I recommend focusing on leveling up your magic materia like Fire, Ice, and Lightning, as they can deal massive damage in battles. Also, don’t forget to link your materia for combo effects – try pairing Elemental with your armor to absorb elemental damage. And always make sure to have a good balance of offensive and defensive materia equipped to handle any situation that comes your way! Good luck, and may your materia bring you victory!
