Lava Ocean
by Mine Co. +
Lava Ocean adds a molten biome to the world generator, where scorching seas and floating volcanic islands replace calm water on NeoForge 1.21.4.
What it does
The mod adds a biome called Lava Ocean, a large expanse of molten lava with small volcanic islands scattered across it. The islands hold rare ores and loot, and underground molten caves contain lava tunnels with hidden treasures and hazards. Players who travel there face a survival challenge, since the lava and the floating islands are dangerous.
Lava Ocean includes new mobs for that biome: Emberfish that swim through the lava and drop Ember Essence, Lava Golems that guard the volcanic islands, and Ashbirds that soar above the lava and drop rare feathers. Fire Lilies grow as heat-resistant floating plants that can serve as potion fuel, and Magma Core is used to craft fire-resistant armor and stronger weapons. Every player and the server need a copy of the mod. Its files target 1.21.4 only and are distributed under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, so the code is not open source.
