Spider Caves
by HexagonNico
Spider Caves, a Fabric and Forge world generation mod, adds an underground spider cave biome and a spider armor set for 1.19.4 – 1.20.4.
What it does
Caves with dense cobwebs and spider eggs generate underground as a dedicated biome. Cobblestone and cobbled deepslate fill the walls, and coal appears in greater amounts than usual. Ruined structures and web-covered chests can be found there. The biome tends to form beneath cold and dry biomes, the conditions spiders favor.
Only spiders, cave spiders and black recluses spawn inside the biome. The black recluse is a venomous spider that sometimes drops a spider fang, which is the crafting material for the spider armor. The armor gives low protection, but a full set gives a chance to poison attackers who deal direct damage to the wearer.
The mod needs Fabric API on Fabric and Phantom Loader on both loaders, and it runs on client and server, so the server and every player need it. Files are published for Fabric and Forge across five game versions, 1.19.4 – 1.20.4. It is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source.
