Xur has returned in Bungie’s Destiny 2 with a range of relatively newish Exotics. You can find him in the Winding Cove in the European Dead Zone, where he will remain until the next weekly reset. In terms of weapons, he’s carrying The Wardcliff Coil for 29 Legendary Shards.
This Exotic rocket launcher fires a volley of rockets in all kinds of directions and can provide some strong DPS (just don’t use it in an enclosed area). It also reloads ammo on pickup. It’s not the best Exotic heavy weapon by a long shot but does a decent job. In terms of Exotic gear, there’s Graviton Forfeit (Hunter helm), Citan’s Ramparts (Titan gloves) and Verity’s Brow (Warlock helm), each for 23 Legendary Shards.
Graviton Forfeit increases the duration of invisibility effects and recharges one’s melee faster while invisible. Citan’s Ramparts allows for shooting through the Towering Barricade though it has less duration and health. Meanwhile, Verity’s Brow provides bonus grenade damage and energy when scoring kills with Energy weapons (and even provides increased grenade regen for nearby allies).
