Destiny: Xur Location and Dark Below Inventory, December 12, 13

Xur: Agent of the Nine is at The Tower in Destiny once again. This weekend, he brought some goodies for owners of The Dark Below expansion.
Xur is back at The Tower to take away all those Strange Coins you’ve been hoarding.
Starting this week and going forward, Xur will have a set of weapons and armor that have a higher rating. You can exchange the old versions you’ve got for new, better versions, but doing so will reset the progress on any of them.
He also brought with him The Urn of Sacrifice, which is something you’ll need to finish a bounty given by Eris.  For this week, Xur decided to hang out by the Crucible vendors. He will remain there until 1am PDT on Sunday, December 14.
The inventory on offer this week is below:

• Ruin Wings [Exotic Titan gauntlets] – 13SC (requires TDB DLC)
• Achlyophage Symbiote [Exotic Hunter helmet] – 13SC
• Voidfang Vestments [Exotic Warlock chest armour] – 13SC
• Truth [Exotic rocket launcher] – 17SC
• Exotic Shard

As for the gear and weapon sets you can turn in for better versions, he’s got the following:

• ARMOUR – Mask of the Third Man, Young Ahamkara’s Spine, The Armamentarium, No Backup Plans, Light Beyond Nemesis, Sunbreakers.
• WEAPONS – Suros Regime, Red Death, The Last Word, Thorn, Icebreaker, Thunderlord.
