Luminous: Nether
by RipleysMods
Luminous: Nether adds two new nether biomes, a set of hostile mobs and a legendary beast family to the Forge and NeoForge nether for 1.21.1 and earlier builds.
What it does
The mod expands the base nether with two biomes, sixteen new mobs and three legendary beasts that carry unique drops and abilities. Three further rare beasts drop their own items. New infectious yellow blocks, a mushroom wood set and fungirack bricks give builders new materials, and ruined portals and structures built into old monster bones appear across the biomes.
Mushlins bounce players back with their heads and drop mushlin protein, a new food source. Piglin cultists carry a cultist axe, cultist leaders summon backup when attacked, and a cultist rider charges into battle on a hoglin. Piglin ghosts stay bound to spawners in the ash forest, spirits attack only when provoked and drop ghostly essence, and guzzleghasts drop ectoplasm balls, a throwable projectile that changes the gravity of blocks.
The mod requires Blueprint and Geckolib, which must be installed next to it on both Forge and NeoForge. Luminous Tag is optional. Nougatadditons requires Luminous: Nether. Biome sizes and weights are adjusted through a separate tweak pack maintained by the same team. Luminous: Nether is not open source and is released under All rights reserved. Its files cover 1.20.1, 1.20.4 and 1.21.1, and the latest Forge and NeoForge builds are 1.3.4, dated 2026-09-28.
