Destiny 2 Xur location: Where is Xur and what Exotics is he selling for April 17 - April 21

This weekend's Destiny 2 Xur location is the back of the Tower, up on the stairs behind the Dead Orbit crowd. Land in the main Tower zone, head to the hangar, and hang a left when you get there. Xur will be there until Tuesday, April 21 at reset time. 

Here are all of the Exotics Xur is selling this weekend. 

• Weapon - Coldheart: deals more damage the longer its beam is held on a target. Coldheart had its time in the sun at the launch of Destiny 2, but it's fallen off tremendously. It loses to Prometheus Lens as a trace rifle, and it loses to most other special weapons in basically every category other than "being a laser."
• Hunter Exotic - Knucklehead Radar: radar remains visible while aiming, and crouching expands your radar resolution. Third Eye is no longer a standard weapon perk in Destiny 2, so the information provided by Knucklehead Radar is pretty valuable in the Crucible. That said, other Hunter PvP Exotics are so strong that it's really not worth the Exotic slot.  
• Titan Exotic - Armamentarium: gain an additional grenade charge. That's it. With all of the Titan Exotics that directly refund and supercharge abilities, merely gaining a second grenade really isn't worth much. 
• Warlock Exotic - Crown of Tempests: kills with arc grenades, melees, and Supers improve the recharge rate of arc abilities and extend the duration of Stormtrance. Crown of Tempests is the go-to Exotic for most Stormcaller builds, and it's the crown jewel of Xur's inventory this weekend. If you have any interest in shooting lightning out of your fingertips, buy this while you can.
