I killed the blade of crota in the fist of crota mission 65 times, 36 on normal 29 on hard. Won't drop. I checked the postmaster for the husk but it wasn't there. Is this the payback I get for getting gjallarhorn from Poe 28 and two days later on a Tuesday getting another ghorn? Edit: 68th try something on the side is loading and I say out loud, "Husk?" and that's when I finally got it.
