So, what exactly are you looking for? Someone raising a mag for you so you can use the mag cell? You didn't tell us what kind of mag you wanted though (stats). Besides, it just requires a level 100+ mag and you can't be an android when using the cell, there's no specific mag needed in case you don't know. Edit: Said requirements are for devil wings, devil tail just needs devil wings (so you need two heart of devils to make tails)
