The Sulfur Cloud is a block from the Natura mod. Sulfur Clouds can be found spawned naturally in the Nether dimension. Entities will not be able to fall through the bottom of the block, or the bottom block of a structure. Entities that have fallen into a Sulfur Cloud will not take any fall damage. Sulfur Clouds break fastest with swords, but can be harvested with anything. Combining 4 Sulfur Clouds in a Crafting Table in a 2x2 pattern will create a single Sulfur.
