So I've googled this for about an hour and haven't found much information, let alone current information. I understand this buff increases prime drop rates, but how why and how long do you get it? I recently started playing again after a LONG time. I started with the prime attunement and still have it almost a two weeks later, never lost it. I check almost every time I get a prime engram but it never goes away. Which if any of the google info is true my sample of information completely contradicts all of it...saying usually it's a daily buff or it has a few hour cool down. Is there any substantial info on this buff out there?
