Hey OP, it's not totally random, what Ruri said next is more accurate. Gear that has crit/det on them have a chance to drop savage aim/might materia along with whatever the other stats are. Example an armor with str/vit/crit can drop str/vit/crit and elemental materia. All DoW/DoM can drop elemental materia. Craft/gather gear drops their respective materia no elemental. Hope that helps!
