Why use Eternal Nether Mod?

While the vanilla Nether offers some structures and biomes, it lacks progression depth. The Eternal Nether Mod fills that void with handcrafted dungeons, dangerous mobs, and lore-driven mechanics that push survival gameplay to new levels. It’s perfect for players who enjoy RPG-like exploration, boss fights, and risk-reward looting. Whether you’re playing solo or building a custom modpack, Eternal Nether turns the Nether from a stepping stone into a full-blown endgame dimension.

FAQs

Is Eternal Nether compatible with other Nether mods?

Generally yes, but structure generation mods may overlap. It’s best used in a dedicated world or modpack built around it.

How do I find the new Nether structures?

Explore Crimson and Warped Forests to locate the Piglin Manor and Citadel, while the Catacombs can be found near basalt or soul sand valleys.

What does the Netherite Bell do?

When used near Piglin Prisoners, it frees them—often rewarding the player or advancing lore elements tied to the structure.

Can I craft the Cutlass and Netherite Shield?

Yes, but recipes may require rare Nether-based materials and are best found via in-game exploration or JEI integration.

Does this mod require a new world to function properly?

Yes, for full structure generation and biome placement, it’s highly recommended to start a new world after installing the mod.
