When descending into a deep cave, the air may run out and the player will die from lack of air. To prevent this, you can wear a moss or paper mask, or fill up a bottle of air before descending into the cave. To craft a moss mask, you need to take 4 pieces of paper and 1 block of moss, and a paper mask can be made from moss and 3 pieces of paper, it will be 2 times worse than a moss mask, but if the moss mask is almost broken, you can use it to your advantage and create a paper mask. Masks allow you to retain air, but if it is almost gone, they will not be able to give you new air, for this you can fill up a bottle of air by pressing the right mouse button on the surface with an empty bottle in your hand. To disable or enable this feature, use /bwd air true/false

As you descend into the caves, cave dust begins to appear around you, adapting to the environment and adding a bit more dynamics to the cave. To disable or enable this feature, use /bwd dust true/false

When you dig a tunnel, with each stone you break, there is a chance that the tunnel will collapse on you. To disable or enable this feature, use /bwd collapse true/false

Sometimes caves may contain enriched stone, which can drop an iron or gold nugget, and enriched deepslate, which can drop a lapis lazuli part or a diamond fragment. To disable or enable this feature, use /bwd enriched true/false

From rotten flesh and bones, you can make miner's soup, which will allow you to eat without leaving the caves.

In caves you can find stone or deepslate with traces of ore, but without ore. To disable or enable this feature, use /bwd ore true/false
