Dependencies

What Dungeon Difficultydeclares it needs, from the author’s own release metadata. A required one has to be installed alongside it or it will not load.

Frequently asked

Does Dungeon Difficulty work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Dungeon Difficulty declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Dungeon Difficulty support?

Everything the author has declared, from 1.18.2 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Dungeon Difficulty on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which platform or loader does Dungeon Difficulty support?

NeoForge, Forge, Fabric. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Dungeon Difficulty?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What does Dungeon Difficulty need to run?

It declares Fabric API and Forgified Fabric API as required, so those have to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Dungeon Difficulty under?

LicenseRef-All-Rights-Reserved, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Dungeon Difficulty?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Dungeon Difficulty safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from Modrinth, where the author last updated it on 9 Oct 2026. We do not host files or republish descriptions. Available download links point to the author’s own release.
