Warframe - Mastery Rank 14 Test

This video shows the mastery test to rank up from Rank 13 to Rank 14. The test involves killing a handful of enemies from each faction. When I played all the enemies were level 1 - it was not difficult. Also, i liked using playclaw and decided to register it. Maybe i should have tested on a video i wasn’t going to actually upload to youtube huh.
