Vintage Story boasts, apart from the functional items and processes, also several phenomena solely added for the sake of making the game appear more alive and even more beautiful. Most of these have no apparent use as of now.
In very cold areas like the worlds poles, the player can encounter weaving auroras in the sky.
Found mostly on grasslands and only at night, fireflies spawn as little clusters of blinking lights.
Going far enough south, the player might notice tiny blue lights following their movements through water.
In some caves, the player might not only find stalagmites and stalactites, but also blue glowing worms hanging from the ceiling. They cannot be harvested nor can they be moved or replanted somewhere else. They emit a light level of 7.
The player can skip stones by throwing them with a shallow angle along water.
