Crystal Star

The Crystal Star is a valuable item and crafting material in Core Keeper. It is notable for being the only valuable item that can also be used as a crafting ingredient, which makes it stand out from other items in its category.

Because of that dual role, the Crystal Star is useful to keep rather than sell immediately if a recipe requires it. Its value makes it desirable as loot, while its crafting use gives it a practical purpose beyond being a treasure item.
