A Bison Carcass is a heavy raw ingredient, obtained by hunting a Bison, that stacks up to 100 units. It is the primary source of bison meat and materials, used in recipes like Butcher Bison, Campfire Bison, and Stuffed Bison. Because it is very heavy at 5500 grams each, you should consider processing it into lighter, stackable ingredients as soon as possible to free up inventory space for further hunting trips.
The descriptive prose on this wiki is written by a large language model — but it runs entirely on local, self-hosted hardware: a Gemma 4 E4B model on a single NVIDIA RTX 4070 in a home Unraid server.
Nothing you read here was generated by a commercial cloud API. The game data itself is pulled live from the Eco server; the AI only fills in flavor and gap text. Like any web server, this one keeps its own request log — including visitors' IP addresses — purely to run and improve the site; it is never sold or handed to a third party.
This wiki is one face of a larger Eco mod: Solomon, an in-world AI steward that runs the server's economy, posts help contracts, keeps a store, and answers players. The wiki reads the same live game registries and tools Solomon does — so the numbers stay true to the running world. Read more about the project →
