Trivia

  • There were once single pieces of Kyanite that could be found in deep Biomes, such as the Blood Kelp Zone or the Dunes as of the Precursor Update.
  • Kyanite is one of the few resources in Subnautica that is not guaranteed to eject smaller pieces when drilling chunks from a large node. This is not a bug.
    • There is a 0.000000471431432% chance for a large Kyanite deposit to yield 22 Kyanite pieces.
