The Nether is expanding! This mod adds more diversity to the underworld with new colorful biomes, unique creatures, and a brand-new ore.
New Biomes 🌲
Two new forests join the Nether, following the style of Crimson and Warped forests:
- Firebloom Forest: A bright forest with yellow tones. Despite its name, it isn't made of fire, but brings a unique golden atmosphere.
- Yemson Forest: A mysterious and dense forest featuring green hues, offering a striking contrast to the usual red landscapes.
New Mobs 🐔
- Netherrack Prowler: A small creature similar to a Silverfish. They spawn frequently and drop Netherrack.
- Debris Prowler: Extremely rare, this Silverfish variant is a lucky find: it drops one Ancient Debris upon death.
- Skeletal Chicken: A passive, skeletal bird. A great source of bones while staying in the Nether.
- Basalt Serpent: A hostile serpent that makes exploration more challenging.
New Ore ⛏️
- Cobalt: A new precious metal (equivalent to diamond)
👉 The mod also adds a new music disc created by LaudividniYT
