Gulden Biome Mod

Author of the Gulden Biome Mod: Sovereign

Gulden Biome Mod adds Foliage fit for gods. A new beautiful biome with some extra goodies and more hopefully to follow.

This biome mod was inspired by the game Elden Ring and was a learning experience for me so I can pump out other biome mods. As such, it will be updated with more content as time goes on either to teach myself new things or just because I think it would fit this mod. Gulden Biome Mod adds a new complete biome intended to make things easier. All plants give beauty as well as a new stone material and sheep’s wool doing the same. As well as a better herbal medicine which is as good as the industrial med, and lastly, a new berry that acts kinda like chocolate reducing recreation.
