In the first few weeks Vault of Glass was out, during my first run in the Gorgon Maze, I opened the exotic chest and relieved an Ice Breaker. No clue what the gun was at that time, everyone with me was freaking out along with myself. I thought I was a badass with this really strong gun no one had. I would sit at the tower and inspect people left and right, no one had this beauty. That was on a Wednesday... Xur strolls through Friday morning with a fresh inventory selling... You guessed, MY ICE BREAKER!! I'm still a bit salty over that lol
