Underground Rooms adds countless new underground dungeons to the world. All of them have loot, enemies and sometimes even traps! Dungeons can spawn with multiple rooms or as a standalone! Some rooms even come with powerful mini bosses to provide the perfect challenge.

Underground Rooms includes single rooms spawning underground, but also full on dungeons with multiple rooms and variations.

Dungeons

The Library

This ancient library is being used by witches for their magical studies. You might stumble across a ruin with a hidden staircase in your world. If you decent the staircase, you will find a huge library with different rooms, loot and deadly witches!

The Jungle Dungeon
This old dungeon was once used as a magical laboratory by a powerful witch. Now only her former familiars are left, protecting a long-lost home ...

The Undead Dungeon
A deadly, mysterious dungeon filled with ritual rooms, tombs and ancient libraries. Beware of undead foes. Though, perhaps you might find some treasure in there ...

The Ancient Dungeon
The Ancient Dungeon is older than history itself. It is filled to the brim with deadly enemies, dangerous traps and even a mini boss!

I'm currently planning the next dungeon! You can leave suggestions in the comments.

Other than that, there are up to 14 single rooms you can find underground.

Alchemy Laboratory: A small room with dungeon loot, a witch spawner, plants and brewing stands.
Enchanting Room: A tiny library with an enchantment table.
Blacksmith room: A blacksmith room with an anvil and a couple of other useful smithing blocks.
Dungeon: A dungeon with 2 cells. Watch it, it's infested with undead!
Throne Room: A huge throne room with dangerous monsters and high-tier treasure!
Library: A big room filled to the brim with magical bookshelves - but beware, there might be more lurking in the shadows ...
Mining Storage Room: A rare storage room filled with ores and blast furnaces. Only spawns in mountains and taigas. Legend says it was once used by dwarfs ...
Treasure Room: The treasure room is an extremely rare room with gold, diamonds and iron. Have fun looting!
Torture chamber: A gruesome place, truely.
Wine cellar: A small room with wine shelves. Beware, there are foes in there too!
Desert crypt: A rare crypt that only spawns in the desert. It's filled with dangerous traps!
End room: The very end has made its way into the overworld - find the end room, it's filled with mysteries.
Hidden temple: A small ruin that rarely spawns in jungles.
The Catacombs: An ancient grave that has been corrupted by magical forces ...

Thats about it! More to be added soon. Have fun! Questions can be asked in the comments, for frequent ones, we will add an FaQ.
