Underground Desert

(needs more information, structure, and organization)

The Underground Desert is a biome found by entering giant holes in the Desert biome. It is mostly made out of Hardened Sand Block, Sandstone Block, and Desert Fossil, with Desert Fossil being the rarest of these. Various ores also spawn in it. It has an elliptical shape to it when viewed on the map.



It is comprised of many small cavities, many of which are connected, creating cave-like formations.

Occasionally, Underground Houses can be found in the Underground Desert

Many monsters spawn in the Underground Desert, including Antlion Chargers and Antlion Swarmers.

Before entering the Underground Desert, it is recommended to have plenty of torches or any other source of light (as with any time you are underground), as well as anything for vertical movement, such as Rocket Boots, Spectre Boots, Cloud in a Bottle, Cloud in a Balloon, Rope, etc.
