Xur is back with some extremely useful Exotics this week, with Hunters winning the lottery. The weapon is one of the best that can be used in Crucible these days so make sure to pay him a visit.
Xur is located on the Rig on Titan this week. To get to him, you will need to spawn on the Rig itself and then look for the red container next to you. Jump over it and continue through the building towards the Solarium. As you exit the building, Xur will be in a small room to the left, as pictured below.
Suros Regime is the weapon he has on sale this week. In case you don't have this auto rifle yet, it is highly advised you do so sooner rather than later. It basically has two modes - one that ramps up fire rate like a minigun would and one that reduces fire rate but gives more damage. Either works great, although Guardians mostly prefer the spin up version.
Hunters can purchase Stompies this week. While Xur's Exotics have low attribute count, these boots are pretty much the best Exotic that Hunters can run in Crucible as they increase movement speed and augment jumping as well as sliding. Perfect for shotgunners and great for everything else.
Titans arguably drew the short straw this week. Stronghold is definitely a useful Exotic but there are better options for literally every situation. These gloves will maximise Guard stats of any sword you might be wielding and guarding at the right time will heal the Titan.
Warlocks have Claws of Ahamkara on the offering this week. It simply grants an additional melee charge, which can fit well into some builds. For example, you can combine it with Entropic Pull in order to charge the grenade quicker while class item mods can help with melee recharge itself. Alternatively, you can use Monte Carlo to have the charges up almost all the time which will allow for spamming both melee and grenade abilities.
