Talk:Mastery Rank/@comment-82.197.193.114-20161017162333

Have a couple questions regarding mastery: if you get mastery xp during 'im able to rank up aka my mastery xp bar is currently full' does it transfer over to the next mastery or is it lost? Also how do I know which weapons and warframes i already gained all the mastery for so i don't build and complete them again?
