About this Mod

About Dimensional Dungeons

Dimensional Dungeons adds limitless procedurally generated dungeons to Minecraft! These dungeons are all placed in a single, separate dimension which can be accessed from a portal anywhere on the Overworld. (Such as in your base!) This makes the dungeons themselves renewable and it provides challenging, replayable content.

The dungeon dimension limits building and block breaking. This allows for an adventure mode-like experience on a survival server. For example, I can use pistons in my traps without giving the player free pistons. Obstacle courses can't be bridged over. Combat can't be trivialized by building fences around mobs. And light and darkness matter when you can't place torches!

Besides challenges in room design the dungeons are also randomly populated with enemies and worthwhile loot! Many rooms with valuable treasure chests require solving a puzzle that will test your knowledge of Minecraft game mechanics. Currently all of the builds are 'vanilla' and no modded blocks or command blocks are used. The goal is to feel vanilla-lite and to be fair to the player.

For modpack designers and server admins there is also a powerful config file which allows for customization of the block protection in the dungeon dimension and many other features. The rooms themselves are configurable in the common config, meaning that you can remove existing rooms or add custom rooms.

How To Begin Playing This Mod

To get started you'll need to build a portal frame, craft some blank keys, and "activate" your blank keys by finding an End Portal Frame. This video describes everything.

There is also a Patchouli guidebook and a Wiki!

Here is a German showcase from VegaCraft which shows a much newer version of this mod:

From The Developer

Four million official downloads! Wow I am astonished! I'm glad so many players have decided to make Dimensional Dungeons a part of their worlds.
Thank you everyone.

This is my first Minecraft mod and I'm very proud of it, but not too proud to listen. Please report bugs, issues and suggestions anywhere you'd like - either in the CurseForge comments section, here on Modrinth, by creating Github tickets, or in the Dimensional Dungeons Discord. I read every ticket and comment. The Discord also has a lot of information about modding this mod and making it do interesting things in modpacks. If you would like spoilers for the puzzle rooms I'll share those too. Puzzle spoilers are now also on the Wiki!

Permission is automatically granted to use this mod in any modpack. I would appreciate a link back to this page, please. If there is a feature or config setting I can add to make your modpack more interesting just request it in the comments and I'll consider it. I care a lot about mod compatibility.
