The Stalactite layer is an underground layer under the Fossil layer and over the lava layer. The Stalactite layer is made of blocks of Stalactite, Siltstone, patches of Saltrock, Mud, Mold and sometimes Glowing Mushrooms. Not many caves are leading down here, but still a number of connected larger caves traverse this layer. In the large caves you might discover smaller pools or cataracts made of Tar, but also many pools and waterfalls made of healing Mineral Water. To mine Stalactite, Siltstone, Salt Rock, Mold, Glowing Mushrooms and Tourmaline you need at least an Obsidian Mining Cell.
