About this Mod
Castle Dungeons
About
Castle Dungeons is a mod that adds procedurally generated castles.
The idea was to make a mod that adds underground dungeons, but such already existed, so I decided to made dungeons on the surface.
This mod doesn't add any new content except structures to the game, so it isn't required on client.
Structures
By default, there are two types of castle: plains and desert.
They are dangerous and full of illagers.
There are a lot of different rooms, which have its own unique loot.
Each castle also has a boss room.
Configuration
Configuration is Data Pack driven. Sadly wiki is not yet written, however you can check how default castles are configured.
Compatibility
This mod supports both Forge and Fabric. It should not conflict with other mods. Please report an issue if you find an incompatibility.
Modpacks
You can use this mod in your modpack as long as you do not redistribute this mod.
