Underground Desert



The Underground Desert is a biome found directly under a desert Biome.

The entrance can be found on the surface in the form of a deep funnel shape, opening into the biome at the bottom. The entrance is always within one of the desert biomes created upon world generation. Each world will have only one Underground Desert, despite potentially having multiple deserts.

The Underground Desert is made primarily of tunnels of sandstone blocks. The Underground Desert can also have Underground Cabins made of its biome-specific materials. It is very large when fully explored, rivaling even the dungeon in size. It has either a circular or oval shape.

The Underground Desert is home to several species of antlion, some of which are able to move and even fly. Due to their high life, defense, and damage, it is advised the player avoid this area until equipped with Gold Armor or better. Additionally, the enemies found here have high knockback resistance, which can prove difficult for players who do not posses strong weapons. Early players will often meet a swift death at the hands of one of the Tomb Crawlers, which can kill a new player in three hits.

In Hardmode, the Underground Desert becomes significantly more challenging. Along with harder enemies, the Underground Desert is extremely vulnerable to conversion by the Corruption, Crimson, and Hallow due to the biome being made of Sand and Sandstone, both of which being susceptible to conversion. Conversion further strengthens the Underground Desert's enemies, and in the Corruption and Crimson Underground Deserts, cause the spawn of Desert Spirits.

Removing the Sandstone background wall will essentially remove the biome, same as with the Spider Caves.

Trivia

 * In real life, larval antlions create funnel-like pits in the ground and fling sand at prey that pass by. The entrance to this biome may or may not be based on it.
