Atheon's epilogue is a legendary void primary, not exotic. Available from normal raid as well as hard. Strongly suggest you consider using the shot gun. Yes it's not your normal play style, but the point of this bounty is to push you to a new challenge. On smaller maps the shotgun will bring you through while you wait on shores of time. You can switch in the initial load screen and retain starting amo Don't forget void ability kills also count. Use a Lmg not a rocket as the Lmg will generate more kills per amo pick up.
