Spider Caves Mod introduces a new spider cave biome into the game. As the name suggests, this is a very large cavity you will find underground while you go mining and it will be infested by spiders. A spider cave can immediately be recognized by the large number of cobwebs spread throughout the cave. The biome comprises cobblestone and deepslate, along with an unusually large number of coal ores. And they usually generate under cold and dry biomes. Spiders, cave spiders and black recluses are the only mobs that spawn in this biome. The black recluse is a new spider variant added by this mod and it is very venomous. Its fangs are needed to craft the new spider armor.
