History of Belisarius-D

Belisarius-D is a Legendary Strand Pulse Rifle (Aggressive Burst Frame, 450 RPM, 42 rounds) made by Hakke.

Overview

Destinypedia calls it the second Pulse Rifle styled after the Lyudmila-D, after Disrespectful Stare, and gives Season of the Wish; the Game Wiki lists Season 23. Game Wiki curated roll: Smallbore, Ricochet Rounds, Vorpal Weapon, Headseeker, Hand-Laid Stock.

Acquisition

Both sources say competitive Crucible (Glory); Bungie's data also lists Forged Anew as a source.

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."
