18 Kelvins

Overview

Adaptive Frame Sidearm dealing Arc damage, from Season 3 (Warmind). The curated roll is Hammer-Forged Rifling, Accurized Rounds and Kill Clip, with Fluted Barrel, Smallbore, Tactical Mag and Opening Shot among the random options. The in-game description is a BrayTech scientist worrying about carrying the weapon after the SIVA project.

Acquisition

Earned through rank-up packages on Mars with Ana Bray, who traded engrams for Seraphite; Warmind Engrams from Sleeper Nodes could also hold it. This is a legacy reputation-era source: the source wiki records that destination tokens and the rank-up system were removed in version 6.3.0 and the vendors moved to the Destiny Content Vault with Beyond Light, so check current availability.
