Sulfur Caves Backport Wiki & Guide

Sulfur Caves generate in the deep underground, typically below Y-level 0, so you'll need to dig well below sea level to encounter them. The exact depth varies based on your world's terrain, but exploring deep cave systems is your best bet for finding these biomes.

Sulfur Caves themselves are underground biomes, but the mod generates rare cave entrances on mountain surfaces that lead down into sulfur cavern systems. These entrances are natural openings you can spot while exploring mountainous terrain.

Sulfur blocks are bright yellow mineral blocks that form the primary cave structure, while cinnabar is a deep red ore that generates alongside sulfur. Both can be mined and crafted into decorative variants like stairs, slabs, walls, and polished blocks.

The mod doesn't require special tools beyond what you'd normally use for stone-tier mining, so a standard stone pickaxe or better will work for harvesting these blocks.

Potent sulfur patches are rare concentrated sulfur deposits found throughout the caves that serve as decorative and functional blocks. They can be mined and used for building or crafting purposes within the mod's systems.

Yes, once you've mined sulfur and cinnabar blocks, you can transport them anywhere and use them for building above or below ground. The mod provides multiple decorative variants including polished blocks, bricks, stairs, slabs, and walls for creative building.

Sulfur springs and waterlogged cave pools are natural features that generate within the biome for visual atmosphere and exploration. They don't have special mechanics beyond being part of the cave environment, though some pools may contain water you can interact with normally.

Pointed sulfur spikes are decorative features that hang from cave ceilings and grow from floors as part of the natural cave generation. They function like normal blocks and don't have special damage properties.

The mod adds new biome generation and blocks, which may have a minor impact on world generation speed, but it's designed to integrate smoothly with standard Minecraft performance. If you experience issues, check that your mod is compatible with your Minecraft version and other installed mods.

Compatibility depends on how other mods handle cave and biome generation—some mods may conflict or override each other's features. Test your mod combination in a test world first, and check community forums or the mod's documentation for known compatibility issues.
