So I've hit a problem trying to infuse the sphere scroll for my Relic, The Yoshimitsu. Currently no matter what grade or type of materia I try to put in it I get the "A materia of a different grade is required." I have a few of each type and no stat is maxed out so I'm not sure what it is. I'm playing on the PS4 and would like a way to fix this. Please and thank you.
