Xur is back with another round of Exotics, some of which will improve their respective class' favourite gimmicks while the weapon is more of a useful utility tool.
Xur is located on Giant's Scar, Io this week. To get to him, go to the aforementioned waypoint and look for the giant building in front of you. Take the path through, in the middle of the structure, and then stick to its left branch until you reach the cave with the regional chest location that you can see on the map. If you are not entirely sure about the exact location, check the image below.
D.A.R.C.I. is the weapon you can look forward to. This sniper rifle goes in the Power weapon slot and is therefore useful for some wonky loadouts, especially in PvP, if you want to occasionally have sniping capabilities while running a hand cannon and a shotgun or something along those lines. On top of that, aiming with D.A.R.C.I. will reveal the enemy's power level, HP percentage and distance, which could be useful tools in build crafting.
Hunters get The Sixth Coyote this week. It is a great all-around Exotic to have since it fits with most builds. Think of it as a jack of all trades but master of none since there are seldom builds that benefit too much around the extra dodge charge.
Titans can look forward to Dunemarchers which are in a somewhat similar situation as other Exotics' power can exceed that of this par of boots but they are still a great thing to have around as they both boost the sprint speed and give the crayon collective AoE damage on their melee attacks.
Warlocks get the Claws of Ahamkara which grant an additional melee charge. It has its uses but is still outclassed by the likes of Transversive Steps, Geomags, Lunafaction boots and many other exotics.
