History of Radiant Stardust

Overview

Radiant Stardust is a Legendary weapon: Submachine Gun (Lightweight Frame), Void, VEIST foundry.

Curated roll per the fan wiki: Full Bore, Hammer-Forged Rifling or Chambered Compensator; Steady Rounds or Appended Mag; Grave Robber (melee final blows reload from reserves). Introduced in Season 2 (Curse of Osiris-era).

Acquisition

Dead Orbit Engrams from the third Season 2 Faction Rally (March 20) onward, via Arach Jalaal and Dead Orbit.

This is a legacy-style reward weapon. It is not a craftable or Adept weapon as far as the sources show, and sunset status was not stated by the sources I opened (the fan wiki is the main source). See also Arach Jalaal and the Crucible for the PvP context.
