How to Get Pyroelectric Propellant in Destiny 2

VS Pyroelectric Propellant is a Legendary Arc Adaptive Frame auto rifle, not an exotic, which is the first thing to clear up. It comes from the Vesper’s Host dungeon on Europa. You earn it from the Raneiks Unified second encounter and the Corrupted Puppeteer final encounter, with extra chances from the dungeon’s secret chests once it is in your loot pool.

Why players confuse it with an exotic

The name and the strong perk column make it feel special, but it is a standard Legendary drop. That matters because the farming method is dungeon runs, not Xûr weekends or Monument to Lost Light currencies. A dungeon key or the relevant annual pass is required to enter Vesper’s Host.

God rolls

For PvE, Eddy Current paired with Jolting Feedback is the standout, with Strategist plus Kill Clip a strong alternative for orb generation and kill chaining. For PvP, Arrowhead Break and Ricochet Rounds stabilize it, while To the Pain up front and Closing Time or Kill Clip to finish reward mag-state and duel play. Its origin trait, Bray Legacy, feeds a small amount of ability energy to the ability closest to full, which helps ability-heavy builds.

How to farm efficiently

Once the weapon is in your pool, the secret chests are the fastest repeat source because they do not require a full clear. Run the dungeon on each character per week for the encounter drops, then sweep chests for extra rolls. Focus fire the Raneiks Unified and Puppeteer encounters if you only have time for one pass.

Pairing Pyroelectric Propellant with Arc builds

Adaptives are steady in both modes, and Pyro’s columns lean Arc synergy, so it pairs well with Amplified or Jolt builds. The broader legendary weapons guide ranks options across the game, and how to get exotics explains why this one is not in that pool.
