CreatureSoaker

The Basilosaurus is a large aquatic carnivore used primarily for soaking. It reduces the weight of resources carried in its inventory, making it efficient for underwater salvage operations. This creature excels at transporting heavy harvests from ocean floors back to bases. It can be airlifted by Quetzal or Karkinos for fast deployment.

Basilosaurus is tamed passively by feeding it. The best food is Exceptional Kibble, which provides the fastest taming speed. Raw Mutton also works if kibble is unavailable. About 14 units of Exceptional Kibble are needed. The process takes around 18 minutes and requires approximately 81 Narcotics to maintain sedation. Use the calculator below for your settings.
