Materia are spheres containing enchantments. Using an enchant changer, it is possible to add and subtract materia from weapons and armor. Each materia contains exactly 1 rank 1 enchantment. Using AP at a materia upgrade shop will upgrade the enchantments on an individual materia to their max level. There also exist master materias containing many enchantmenta at their max levels.
-After adding a materia pulling it out from a weapon will remove its name.
-A weapon cannot be upgraded to level 2 at a weapon shop until all materia minus 1 everlasting materia are removed.
