Dripstone caves were added to Minecraft in the update v1.17 in the Caves and Cliffs update. They are very large cave-type biomes that contain huge rivers. They are an Overworld cave biome that is filled with clusters and pillars of pointed dripstone and dripstone blocks.
Dripstone caves generate underground at any height and they favor areas that are far inland, which means they're essentially never found under ocean biomes or while bordering a coast. Dripstone blocks and pointed dripstone blocks can be found hanging from the ceiling and on the ground.
They mostly appear like regular caves except with patches of dripstone blocks and pointed dripstone. Large dripstone cluster structures generate occasionally inside ravines. This biome also generates larger copper ore blobs compared to other biomes.
Dripstone caves are filled with hostile mobs as the light level inside is very low. Players will encounter spiders, zombies, zombie villagers, skeletons, creepers, slimes, endermen, witches, bats, chicken and zombie jockeys.
