Xur is an exotic and legendary item vendor who only appears from Friday to Sunday and we have his location and inventory for friday, October 10th.
The exotic weapons he sells require 23 strange coins and the armour requires 13 strange coins. He also sells legendary ships and ammo synthesis that require strange coins.
He won’t be at the tower for a long time so if you can farm the required items fast you can purchase what he has to offer. Weekly Heroic Strike offers a lot of strange coins on completion at a higher difficulty. You can also gain them from decrypting rare and legendary engrams.
His location and inventory are as follows:
He is right to the Speaker’s area and he is selling the Icebreaker sniper as well.
So what do you think? Did he sell something that you wanted for your character?
