I've got everything but the crux, but I've only done HM 5 times. Of the other weapons HOC and light of the abyss alluded me for a long time. Black hammer, Song of Ir Yut, Swordbreaker all dropped early on normal, Abyss Defiant, Oversoul Edict, Fang (1 on each of 3 HM runs), WOC (5th HM run) all dropped early. HOC finally dropped last week and the fusion rifle was after reset this week.
