Xur has arrived for the first time in Beyond Light and players can find him in a core location, possibly so he doesn't cause too much confusion if there is indeed a location on Europa.
You can find Xur in the Tower hangar this week, in the location the veterans usually call "behind Dead Orbit" vendor. If you are unfamiliar with it, just go to Amanda Holliday and turn left as you reach her. Continue through the hangar towards the landing pad and you will see Xur to the left on a catwalk, as seen on the image below.
Lord of Wolves, once a terror-spreading weapon in the Crucible is now an Exotic people barely use. That said, it is not a bad one per se, it simply fell out of favour after heavy nerfs. It can still one-shot roaming Supers but it remains to be tested against the tanky Stasis Titans.
Hunters are getting a decent Exotic this week in Raiden Flux. It is useful in both PvE and PvP if you are a fan of the Arc Staff specs. Each subsequent hit increases the Super's damage, making it more potent against bosses. The Exotic also makes the Super's duration increase with every strike which is extremely beneficial in both PvE and PvP. Consider pairing it with another Exotic chest piece that is useful in between Supers for quick swaps. Dragon's Shadow is perhaps one of the best complements.
Chormatic Fire is excellent for Warlocks who use their Kinetic weapon a lot in PvE as kills with it will create explosions in the element of your subclass, which is highly useful for clearing hordes of enemies.
Titans drew the short straw this week as they are getting Aeon Safe. Buy it for giggles if you are looking to waste some Legendary Shards.
