The Underground Oasis is a relatively basic structure that spawns anywhere in the Betweenlands Cavern or Lake Cavern layers. It is a patch of grass with various plants, most abundantly Weeping Blues, Bulb-Capped Mushrooms, and sometimes even a Giant Bulb-Capped Mushroom. Its ceiling is also littered with a larger than usual amount of Stalactites. However, it also contains a central spawner.
This location, despite its risks, can be a relief to players lost underground in search of restoring Decay and may also be a prime place to set up a mob farm.
