Older Sister III

Overview

Older Sister III is a Legendary Solar Hand Cannon on the Adaptive Frame, built by SUROS. It fires at 140 RPM from an 11-round magazine, and the D2 Wiki gives it an optimal PvP time-to-kill of 1.30 seconds with two critical hits and two body shots. The curated roll is HitMark HCS, Alloy Magazine and Ambitious Assassin, a trait that overflows the magazine as you defeat targets. Its flavor text is a line from Executor Hideo: "To protect us, as she once protected me."

Acquisition

Part of the New Monarchy weapon pool from Year 1, released in the base season of Destiny 2. It came from New Monarchy Engrams awarded for ranking up with Hideo during an active Faction Rally. It has no craftable or Adept version listed in the sources I opened.
