Ros Arago IV

Overview

Ros Arago IV is a Legendary Void Auto Rifle with the Adaptive Frame ("a well-rounded grip, reliable and sturdy"), made by Cassoid and listed in the Energy slot by the Destiny 2 Wiki, which dates it to Season 23. Its curated roll is Hammer-Forged Rifling, Alloy Magazine, Permeability and Golden Tricorn, with the Wild Card origin trait. Blueberries.gg recommends Arrowhead Brake, Accurized Rounds, Rewind Rounds and Onslaught with a Range masterwork for PvE (Arrowhead Brake, Accurized Rounds, Dynamic Sway Reduction and Onslaught or Golden Tricorn for PvP) and rates it B-tier in PvE, saying it depends heavily on Onslaught.

Acquisition

Open Legendary engrams and earn faction rank-up packages. Blueberries.gg calls it a world drop that is not craftable and suggests running Terminal Overload on Neomuna to get world drops.
