Warframe Mastery Rank 12 Achieved!deveerei (68)in #warframe • 6 years ago Featuring my Dark Blood Zephyr Prime! I was able to finish the Mastery Rank 12 test in Warframe. Now I'm a Gold Seeker. It's an easy test. All I had to do was run around in a circle to avoid the spinning laser obstacles while shooting a few enemies. Thanks! #game #games #gaming #philippines
