History of Faith-Keeper

Overview

Faith-Keeper is a Legendary Void Rocket Launcher from Episode: Echoes (Precision Frame rocket). Like other Echoes weapons it carries the Radiolaria Transposer origin trait tied to Radiolaria fluid. Community roll guidance (TheGamer-style PvE picks): Auto-Loading Holster with Bipod or Explosive Light.

Acquisition

Destinypedia lists Faith-Keeper among the Act 1 rewards of Breach Executable, the three-player Vex zone-control activity on Nessus. Echoes weapons are Legendary and were not covered by sunsetting. None of the sources I opened confirmed whether a craftable pattern exists or an Adept variant, so check in-game. See also Weapon crafting and Episode: Echoes.
