Xûr is Destiny 2’s Exotic gear merchant. He appears every weekend to sell the game’s most coveted items in exchange for Legendary shards, but if you’re a casual player with limited shards to spend, it can be hard to know which of his wares is most worth your investment. That’s where we come in.

Xûr appears every Friday at 17:00 GMT (09:00 Pacific), and will stick around until the Tuesday reset. We’ll update this guide shortly after he arrives, so if you’re reading this, you need only read on to learn where he is, and which are the best items he’s selling this week.

Ever since the Forsaken expansion, Xûr’s icon no longer appears on your director, so he’s not quite as easy to track down as he used to be. That said, his appearances in the EDZ, Titan, Nessus, Io, and The Tower have so far been in the same places he frequented in vanilla Destiny 2. When he appears in the Tangled Shore or Dreaming City (as he surely will) we’ll be sure to let you know exactly where.

Xûr is back at the EDZ this week, near Winding Cove. He is selling:

Graviton Lance, an Exotic energy pulse rifle, for 29 legendary shards
Celestial Nighthawk, an Exotic Hunter helmet, for 23 legendary shards
Dunemarchers, Exotic Titan leg armour, for 23 legendary shards
Sanguine Alchemy, Exotic Warlock chest armour, for 23 legendary shards
A Fated Engram, which guarantees a non-duplicate Exotic, for 97 legendary shards.

Graviton Lance certainly looks and feels as cool as an Exotic should, but in gameplay terms it’s nothing special. Its perks will cause killed enemies to explode, and will cause the third round in each burst to do high damage with no damage falloff. The explosion can spread around some splash damage and the lack of falloff gives it essentially limitless range, both of which can be advantageous in PvE, but Sunshot’s splash damage is better for sweeping up adds, and range alone isn’t an argument for Graviton Lance – several Legendary scouts (especially Nameless Midnight and Call to Serve) have all the range you’ll need, are more consistent, and won’t take your Exotic slot. If you want to use Graviton Lance anyway, learn to fire it so that third round lands every time. The first two are pointless.

Celestial Nighthawk is a Hunter helm that modifies a Gunslinger’s Golden Gun to fire a single, high-damage bullet. Enemies killed by this shot will explode, and it can still score critical hits through the Sharpshooter tree. Such a hit will do crushing damage to any target, but limiting your Golden Gun to just one round hurts your overall orb generation, which is one of a Hunter’s key jobs on a raid team. If you’ve got someone covering that role, though (like a Nightstalker with Orpheus Rig), then this is well worth considering. The addition of Masterwork weapons, which also generate orbs quickly, further frees up Gunslingers to play damage dealer rather than support. It’s utterly useless in PvP, but for strikes and raids, Nighthawk offers one of the best single shots of damage in the game. Probably worth the purchase.

Dunemarchers have Linear Actuators, which increases sprint speed and allows your sprints to build up a static charge. If you wrote this one off early on, give it a second look – the charge-up time has been significantly reduced, and the chain damage from the chain lightning that results has gone way up, too. Combined with the more general buffs for Titan melee around Forsaken, this one is a very attractive option.

Sanguine Alchemy gives you Heightened Senses, which lets you continue to use your radar while in ADS. Nearby enemies will be marked so that you can track them without line of site, too. Yes, this perk is pretty dull. You can probably put together a build that supports it well enough – and the armour looks cool enough that maybe that’d be worthwhile – but in terms of usefulness, there are many better ways to spend your shards.
