Destiny's Xur is back in the Tower again this weekend, where you'll find him located by the Jukebox in the bar by the hangar bay.
As usual, he'll have some Three of Coins and Glass Needles to sell to you, which you can use to get fancy Exotic engram drops or re-roll the stats on your Exotic armor, respectively.
The enigmatic space trader will be around from now until early Sunday morning, so be sure to catch him before he departs. Keep in mind that you'll need Strange Coins to buy his items.
Here's what he's carrying:
Legacy Engram [Chest armour engram] – 29SC
Empyrean Bellicose [Exotic Titan helmet] – 13SC
Skyburners Annex [Exotic Hunter helmet] – 13SC
Alchemist’s Raiment [Exotic Warlock chest armour] – 13SC
Thunderlord [Exotic machine gun] – 17SC
Three of Coins – 7SC
Glass Needle – 3SC
