History of Corrasion

Overview

Corrasion is a Legendary Arc Pulse Rifle from Episode: Echoes (two-burst frame). Like other Echoes weapons it carries the Radiolaria Transposer origin trait tied to Radiolaria fluid. Community roll guidance (PvE picks per TheGamer): Perpetual Motion and Frenzy.

Acquisition

Destinypedia lists Corrasion as an Act 2 weapon earned from Battlegrounds activity on Nessus; Dexerto also names it among the episode's new weapons. 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.
