Amethyst Nether is a datapack and mod that transforms the Nether by giving it a new appearance, adding biomes, structures, mobs, items, recipes, advancements, and more. ## 📝 Description The project was released in December 2022. It was created by amethyst137 and continued by bbschef, who is currently in charge. It is recommended to use Amethyst Nether in new worlds, and it **cannot be removed once applied without a reset** (reading the wiki is recommended to learn how to apply it correctly). World generation uses custom noise values and density functions to modify the terrain, giving it a more cavernous appearance. It includes rivers, caves, canyons, and more. ## ✨ Features

Mechanics

#### Piglin Infection Hoglins, Piglins, and Piglin Brutes receive the weakness effect while inside the Wart Heap biome. If they are near heap fungus, they transform into undead mobs.

This prevents players from passing through the bedrock roof.
