History of Ill Omen

Overview

Ill Omen is a Legendary Stasis Sword from Episode: Echoes (Caster Frame). Like other Echoes weapons it carries the Radiolaria Transposer origin trait tied to Radiolaria fluid. Community roll guidance (PvE picks per TheGamer): Relentless Strikes with Surrounded or Cold Steel.

Acquisition

Destinypedia lists Ill Omen among the Act 1 rewards of Breach Executable on Nessus. Echoes weapons are Legendary and were not covered by sunsetting. None of the sources I opened confirmed whether a craftable pattern exists or an Adept variant, so check in-game. See also Weapon crafting and Episode: Echoes.
