Underworld Oasis

"There's small patches that remain of how the Underworld used to be, these oases can be found rarely within the molten hellscape." The Underworld Oasis is a kind of structure that can rarely spawn in the Underworld. These regions often flourish with more surface elements being present. While many unique items and many things usually not present in the Underworld are in the Oasis, due to the Oasis' status as a refuge from the hellish landscape elsewhere, many strong enemies are in the Oasis as well.
