you need like 328 Photon Spheres for a Lv200 mag right? some easy solo PD runs or general EQ's in general with 10* drops. I also think you get that mag device item from Main Missions either for leveling or something else, I know it didnt require leveling your Mag to Lv100 because during the NA CBT i got that box with the Mag Food Devices in them and my mag went straight to Lv70
