Okay so I got Destiny like 2 Weeks ago and I only have a couple hours invested to it. I'm a Level 24 and when I got to Xur (just to browse), he has all these exotics. And the prerequisite for these exotic weapons is confusing. For example, Thorn requirements need "Thorn 0/1" Im a little confused because how does purchase a thorn even when it say to hand in a thorn to purchase a thorn? Sorry if this doesn't make any sense but I was curious on how it works. Also, when I first played Destiny, the area behind Xander was open and it was a really cool place. But now it's closed and I don't know why. My friend said it was something about the Iron Banner or the Queen or something. Can someone further explain? Thanks for the Help! I'd really appreciate it.
