Basically, a whole lot of “meh”.
Exotic vendor Xur has returned to the Tower in Bungie’s Destiny. You can find him in the hangar where he will remain till April 9th, 2 AM PST.
This week, Xur is carrying the Crest of Alpha Lupi (Titan chest), Shinobu’s Vow (Hunter gloves) and The Ram (Warlock helm), each for 13 Strange Coins. Shinobu’s Vow and The Ram recently saw nerfs, making them less effective for PvP. Crest of Alpha Lupi is as straightforward as ever, helping you to revive your allies faster.
Otherwise, the Invective is worth checking out. The exotic shotgun costs 17 Strange Coins and regenerates its ammo over time (one magazine at a time though).
Then again, it’s not Icebreaker nor does it have the range of a sidearm in PvP. Pick it up if you don’t have any other Exotic shotgun for PvE purposes. The Legacy Engram, meanwhile, is a Year One Special Weapon engram which costs 31 Strange Coins.
