Structure
The world of Better than Adventure! has a share of pre-generated structures that infrequently generate in the world. There are only structures in the overworld as of now.
Dungeons

Dungeons are structures that are usually found deep underground. They are small, cubic rooms that often feature chests and one monster spawner.
Labyrinths

Labyrinths appear as a medium-to-large collection of hallways, both horizontal and vertical, that are found underground. Some may have entrances on the surface. They often contain traps, monster spawners, and precious loot. Refer to here for more in-depth information.
Upcoming Edit
- Quarries are planned to naturally generate in the Nether once the Warrens are added. These will be the ideal way to bypass the layer of Soul Slate, and will also contain treasure.
- Villages occupied by Pigmen may be added to Paradise in the future.
- Paradise will likely have a few dungeons, due to it's emphasis on exploration.
