  • Total number of Pustrels to be mined from an ore depends on the distance from the Cetus gate, starting from 3 and up to 6 towards Mount Nang. Note that these numbers are the result of fast mining that is made without waiting for perfect heat gauge alignment. The numbers will be higher for perfect mining, however, the time spent for each ore will also be higher whether or not it gives Pustrels. Please refer to Mining page for more detailed calculations.
  • Cannot be obtained from Tusk Thumpers regardless of variant.
  • Joining a Railjack squad for Empyrean missions is a way to gain large amounts of ship materials, including Pustrels. Use recruiting chat to matchmake, as clicking on the node does not automatically do so, yet.


  • With their design clashing with the more natural look of ores and gems, Pustrels and are most likely the result of the Infested boil that crashed into the Plains in Operation: Plague Star.
