THE CRYSTAL BARROWS

(the place you use your treasure keys, common people stop asking). The crystal barrows is the place where you want to sit back, relax and kill Xur for all those stupid heroic strikes for collecting strange coins. Apparently one of these Prison of elder missions has a 100% garentee on getting an exotic. Soo instead of farming those shiny stupid rare coins and collect my shiny great purple keys from chests and spam the chest with all those keys. Think of how many different exotics there is going to be. Every key= exotic. And if this is true, goodbye 200 strange coins.
