I have attempted the sever- rage multiple times with different weapons, loadouts and it will NOT complete. I have had several friends look my char over and they said it should have worked. Nothing but void subclass , void and stasis weapons, and all for nothing. 7 times I have tried to no avail. What gives bungie?????????
Your weapon has dragonfly. If that procs & kills an enemy, then that will cause the challenge to fail. It will also fail if you explode barrels to kill an enemy or use the scythe.
Edit….the Rage season challenge requires arc, not void.
