Black Core

Black core is a resource found in the Mistlands, and it is the key crafting ingredient needed for several late-game stations. It can only be obtained from Infested Mines, where it most often appears on stands in hidden rooms, though it can also be found in other rooms.

The number of Black cores in a mine varies widely because room layout is randomly generated. Infested Mines can have between 16 and 96 rooms, so some mines contain no cores at all, while others can yield more than 10. In practice, most mines contain at least two Black cores, but there is no guaranteed minimum.

Black cores are used to craft some of the most important Mistlands progression structures:

• Black Forge: 5 Black cores
• Eitr Refinery: 5 Black cores
• Galdr Table: 5 Black cores

Because each of these stations requires five cores, it is usually worthwhile to raid multiple Infested Mines before trying to fully set up a Mistlands base. The hidden rooms in particular are the best places to search, since they are the most common source of Black cores. When exploring, check every side room carefully and clear the mine methodically so that no stands are missed.

Since their distribution is so variable, Black cores are one of the main reasons players may need to revisit the Mistlands repeatedly. A fortunate mine can provide enough cores for several essential stations at once, while an unlucky one may provide none, making careful exploration more important than speed.
