Materia is one of the most interesting magic systems in the series. It is the biggest gameplay mechanic that has carried over from Final Fantasy 7. It did not change on how it was used in Final Fantasy 7 Remake and its usage hasn't changed in Final Fantasy 7 Rebirth. Players can buy or acquire Materia through side quests, and there are five types in all: Magic, Support, Complete, Summon, and Command.
