If you're playing Destiny, you may be aware of Xur, the weekly exotic-item merchant who arrives in the tower on Friday at 4 a.m. ET and departs on Sunday at 4 a.m. ET. If you're a casual player, it can be hard to know where your hard-earned Strange Coins are best spent.
Watch the above video for a quick review of Xur's inventory this week, and if you're a warlock, sign on to Destiny now to go buy the Heart of the Praxic Fire.
If you're short on coins, the Weekly Heroic strike at level 30 will earn you nine, and then your best bet for additional coins is to run Roc strikes for blue engrams.
