Sulfur Caves Plus
by CrossFace22
Sulfur Caves Plus extends the Sulfur Caves biome with new ores, a venomous spider, lava geysers and a corrosion status effect that wears down armor.
What it does
Sulfur Caves Plus extends the Sulfur Caves biome that arrived with Minecraft 26.2. Sixteen new ore blocks generate inside the biome terrain, and a venomous spider variant appears only there. The spider carries a sulfur spike tail and bites with a Corrosion effect, a harmful status effect that damages armor durability over time. Potions of Corrosion are part of the content too.
Volcanic lava geysers are another addition. A geyser is built from Potent Sulfur lava above a Magma Block, launches entities upward like regular geysers, deals fire damage and ignites what it hits. Lava pops scale with geyser height. Geysers pass through copper grates and open trapdoors, and the biome also generates Basalt Deltas and Treasure Bastions naturally. The Unbreaking enchantment partially resists the corrosion damage, more at higher levels.
Sulfur Caves Plus requires Fabric API. The mod is published for Fabric and NeoForge for 26.2 and 26.3, with snapshot builds published, and it is released under All rights reserved, so it is not open source. A server running it needs every connecting player to have it too.
