To raise the percentage added to the medal's damage you don't need to use more 6 star medals but yes magical mirrors. You can get them in some quests or in the coliseum, raid boss, and multiplayer boards ~ one magical mirror used on the medal raises the guilt by 1%

After playing khux na until the actual quest i must say that if agrabah is in kh3 then i'm probably going to have vietnam flashbacks
