"Do not hesitate to use alien lifeforms for survival purposes, but always search for unexpected complexity." — PDA upon first collection of Lucifer Rotsac

The Lucifer Rotsac is an anchored Lifeform similar to Earth's tunicates. It can be picked up by the player as a Raw Material and used to craft Rubber and Grease. It can also be grown in a Growbed.

Appearance

The Lucifer Rotsac has a simple bulbous body that produces a bright orange luminescence. It lives in a symbiotic relationship with the Cradle Shootroot.

Obtaining

Lucifer Rotsacs always appear growing on top of Cradle Shootroots, from which they can be picked by hand.

After a while, they will regrow and can be harvested again.

Lucifer Rotsacs can be grown by planting a Cradle Shootroot in a Growbed.

Uses in Crafting

  • Rubber
  • Grease

Databank Entry

Tentatively Rotsac lucifer, the light-bringing rotsac. A tunicate-like animal which ferments decomposing biomatter inside its body.

  1. Hidden body: The rotsac's larval swimming body transforms into a spherical adult form. Because fermentation does not require oxygen, the rotsac actually stops breathing as it matures.
  2. Swollen with hydrocarbons: The rotsac contains isoprene, useful for fabricating rubber and lubricant. High diacetyl levels give the rotsac a strong caramel funk.
  3. Bioluminescence: Glow may attract animals (especially sun-seeking microorganisms) to defecate or die on the rotsac. Bioluminescence seems to play an important role in this world's ecology. Regular experiments with light reactions are advised.
  4. Symbiote: Often found glued to the cradle shootroot, an unrelated species of starfish-like bottom-dweller that provides the rotsac with an anchor while it grows.

Assessment: Useful source of organic polymers for rubber and oil.

Consult your Noetic Advisor to research optimal search areas.

Trivia

  • The name “Rotsac” refers to their metabolism, producing oils by internal fermentation, whilst “Lucifer” means “light-bringer”, referring to its bright orange luminescence.
  • The player is able to throw the Lucifer Rotsac.
