Black Market vendor Xur, the Agent of the Nine, appeared again today, but on another location. He’s still in the Tower, but instead of heading left into the speaker’s chamber look right, he’s in that area. This vendor appears only during the weekends from Friday, until Sunday. He also has material exchange. For 2500 glimmer you can get a Strange coin. You can also make an exchange with 77 spinmetal and 77 spirit bloom.
