History of Basso Ostinato

Basso Ostinato is a Legendary Void Shotgun with a Rapid-Fire Frame (140 RPM, 7 rounds), introduced with Lightfall.

Overview

Game Wiki curated roll: Rifled Barrel, Extended Mag, Lead from Gold, Adagio and the Nanotech Tracer Rockets origin trait.

Acquisition

Both sources list Terminal Overload: Destinypedia says Ahimsa Park, the Game Wiki says Ahimsa Park or the Stage 3 chest, plus a weekly challenge from Quinn Laghari. Destinypedia states it is craftable (requiring 5 pattern completions); the Game Wiki does not mention crafting, so this is not confirmed.

The two opened sources (Destinypedia and the Destiny Game Wiki) disagree on some details such as the season of introduction, and neither states whether the weapon can be crafted or has an Adept version, so those are treated as not stated. Bungie's in-game source text reads "Random Perks: This item cannot be reacquired from Collections."
