Hey there! When it comes to materia management in Final Fantasy VII, it’s important to prioritize which ones to level up. I recommend focusing on leveling up your Magic materia first, like Fire, Ice, and Lightning, as they can be powerful in battles. Pairing them with Support materia like Elemental or Added Effect can also be very effective. Don’t forget about Command materia too, such as Steal or Enemy Skill, as they can provide useful abilities in different situations. And always make sure to equip your characters with a good balance of offensive and defensive materia to handle any challenge that comes your way!
