Pustrels were a common Resource dropped by Eximus units found in the Infested Ship tileset, primarily on Eris. They could also be found in Empyrean missions as a possible loot drop from destroying Grineer ships, killing Grineer ground units, or opening storage containers found on Crewships. They were used in constructing, upgrading, and maintaining the Railjack.

Gathering Tips[]
- Pustrels are significantly more common in Empyrean than in the Infested Ship tileset.
- Kuva Lich and Arbitrations missions can spawn Eximus units more often as a result of their higher level, allowing for easier farming.
- Any Endless mission types on Eris is a great source for Eximus units, with higher waves spawning more Eximus units.
- Pustrels may be dropped as an end mission reward of Railjack missions at amounts of 1200, 1500 or 2700 depending on luck. (Empyrean Rewards)
Notes[]
- When running Empyrean missions to farm Pustrels, all Pustrels, Carbides, Cubic Diodes, and Copernics are stored in the Railjack's Resource Forge in order to manufacture consumable items. The Forge holds a default of 200 of each resource, after which additional gathering is automatically distributed to the squad, until the mission is completed. Pressing the "Refine" button from one of the Forge station will distribute the resources to the entire squad.
Trivia[]
- Prior to Update 28.0 (2020-06-11), Pustrels could be found through Mining on the Plains of Eidolon. Despite this, they would not drop from any Tusk Thumper.
- With their design clashing with the more natural look of ores and gems, Pustrels are most likely the result of the Infested boil that crashed into the Plains in Operation: Plague Star.
- Update 27.0 (2019-12-13) introduced the ability to get Pustrels (and some other resources) through Empyrean missions in the form of loot drops and successful mission rewards.

Patch History[]
Update 29.10 (2021-03-19)
- Removed from drop tables.
We wanted to reduce the number of Resources we introduced in our original Railjack launch. They'll remain in your Inventory as we’ll be looking at possibly reintroducing them at a later date. All Blueprints that required these items have been updated to reflect viable Resources, and respective drops have been swapped to Ticor Plate where appropriate. These Resources have also been removed from Helminths Bile Feeding menu. If you spot any mentions of these Resources that we might have missed please let us know!
For Tenno who have partially contributed these Resources to Wreckage, the percentage of your contribution will be honoured for the Resource that replaces it. Ex: If you contributed 60% of the needed Copernics for a Carcinnox, that 60% contribution will be carried over when the Blueprints are updated.
Hotfix 28.0.5 (2020-06-17)
- Fixed Pustrels description to their updated drop locations.
Update 28.0 (2020-06-11)
- Removed Pustrels from Mining Nodes in the Plains of Eidolon and added to Eximus enemies in the Infested Ship tileset.
Update 26.1 (2019-11-22)
- Introduced.
