Xur is back for another round of Destiny 2 Exotic sales, offering another set of items, some of which are highly useful as the weapon is great, Titans' Exotic is awesome, Warlocks' so-so and Hunters' is situational.
Xur is located in Watcher's Grave on Nessus this week. To get to him, just port in on the aforementioned waypoint and you should be able to spot a golden barge. Go underneath it, climb the rock formation and enter the cargo hold. Proceed up the ramp until you reach the deck and the tentacle-y vendor will be next to a bunch of golden chests.
He is selling the Black Talon sword which has a great catalyst that will offer a massive damage increase after block but the weapon is highly useful even without it. It will one-shot enemies in Crucible and the heavy attack fires projectiles so you don't always have to close the gap entirely. Black Talon is even more useful in Gambit as Heavy ammo is plentiful, offering a potent way to invade or deal with enemy invaders.
Titans are getting Dunemarchers. These are the exotic boots that will make punch-happy titans ecstatic, which pretty much accounts for the entire Titan population. They inherently increase sprint speed and build Arc charge up. Punching someone will release the charge into a damaging AoE effect, making the item highly useful in Crucible, Gambit and regular PvE. Still can't compare to Antaeus in Crucible but that one is overpowered so it's unfair to rate Dunemarchers badly because they can't keep up.
Warlocks are getting Claws of Ahamkara, a pretty straightforward Exotic pair of gloves that gives you two melee charges. These allow for some creative builds but they are normally outperformed by other Exotic armour pieces.
Hunters are getting Mechaneer's Tricksleeves, with rather interesting timing. These gloves improve your sidearms' reload and ready speed on top of increasing the weapon's damage, should you switch to it while critically wounded. The critically wounded part makes the damage increase hard to activate, especially in PvP and there are pretty much always better Exotic alternatives.
However, the timing for Xur carrying them is curious since we are about to get another Exotic sidearm, which may or may not pair well with the gloves. It might be a good idea to grab them - better safe than sorry.
