I've killed way over 150 blades of crota since the guns been available, and have been farming for about an hour today on the fist of crota mission so far and still nothing.. Any tips on something I may be doing wrong? Update1: been going non stop 2 hours, nothing so far, lost track of kills. Sick of these black wax showing up and making me excited xD Update2: 2 hours 36 minutes and I finally received the husk of the pit! Thanks to all that replied! Have a great day! :)
