How to acquire Master Materia - FF7 Guide

Any time after collecting the Huge Materia during Disc 2 you will be able to do the Master Materia Side Quest. In order to get a Master Materia you'll need to have collected the appropriate Huge Materia as well as mastered a majority of the Materias that fall into whatever category you want the Master Materia for.

So, for example, if you want a Master Magic Materia you'll need to master all of the different Magic (green) Materias then inspect the green Huge Materia in Bugenhagen's house. All of the mastered magic Materia will be removed from your inventory and you'll be given a Master Magic Materia.
