DIfficulty Overhaul
by Atlantic-
Difficulty Overhaul is a server-side Fabric mod that makes survival harder by making hostile mobs adapt and grow stronger the longer a world is played.
What it does
Hostile mobs change over total world playtime, so a world that has been played for a long time becomes more dangerous than a new one. The mod also rebalances core survival mechanics to remove safe loops such as idling in one spot, pushing players toward movement, precise timing, combat tactics and careful management of resources. Its author describes the result as unforgiving and unfair on purpose, aimed at veteran players who have already mastered basic iron and diamond gear.
The mod is distributed for Fabric only, and it requires Fabric API as a dependency. The server must run it, while players may leave it out; installing it on a dedicated server is enough to change the experience for everyone who joins. Singleplayer worlds work too when the mod is placed in the local mods folder with Fabric API. The mod is released under the MIT License and is not open source. Its only game version is 26.1.2, with the 1.0.0 beta build published on 2026-05-26.
