Spelunker Potion

Spelunker Potion is a potion with an effect that lights up Cavelings, making them easier to spot in dark underground areas. This gives it a practical use in caves and other low-visibility places, where enemies or creatures can otherwise blend into the surroundings.

Because its listed effect specifically applies to Cavelings, the potion is most useful when exploring biomes or spaces where those creatures appear. In practice, it can help with identifying them sooner and keeping track of them during combat or exploration, especially when lighting is limited.
