well frostfire isn't from the cryptarch. It's from the Vanguard packages because I just got another one. Apparently they're extremely rare though. I've never even heard of arctic proxy until I got mine, & it's soooooo nice. lol, it's beautiful. I can't believe it's only a blue quality shader. people go wild over God of war too though. I guess it's super rare. I had no idea because I've hadda few. But I saw a couple of different threads over the time explaining how hard they are to come by. Right now I think my favorite shader is the Trials one though. It just looks really nice on a lot of the warlock gear.
