Restless Legions
by Nebulacrity
Restless Legions turns the regional difficulty system upside down, so that chunks start with a difficulty of 0 and grow harder the longer players stay in them.
What it does
In vanilla Minecraft, regional difficulty is tied to how much time players have spent in an area and to the moon phase, which means mobs in long-visited regions can already carry enchanted armor and potion effects early in a world. Restless Legions reverses that pattern: a chunk is no longer 0 by default only in the sense of starting safe, and the difficulty instead builds up gradually with the habitation value that players create by staying nearby.
The mod is intended for survival worlds where players want a steadier progression, and it runs on the server alone, so players join without installing it. It is published for NeoForge only, for 1.21 – 26.2 across 16 release versions, and the license is MIT, though the code is not open source.
Key features
Inverted regional difficulty
Regional difficulty starts at 0 in every chunk and rises over time instead of being present from the beginning.
Player-driven habitation
The habitation value of a chunk grows as players remain in it, so the danger increases where they spend the most time.
Moon phase factor
Each moon phase changes regional difficulty in chunks differently, and the effect is kept in the calculation.
Overwritten vanilla method
Restless Legions achieves its effect by using mixins that replace the calculateDifficulty method found in the vanilla DifficultyInstance.java file, altering the regional difficulty logic where it is computed.

Use cases
Long-term survival progression
A world stays calm near the spawn for a while, and difficulty rises in areas that players repeatedly visit as the game goes on.
Testing habitation values
Players who want to study how habitation affects difficulty can keep a chunk occupied for a long time, with the local difficulty shown in the F3 screen.
Who it’s for: Server owners and survival players who want regional difficulty to grow with their presence rather than appear early, and who run a NeoForge world.

What the author says
Deep within Minecraft's code, where people seldom venture, lies a relatively-unknown system called 'regional difficulty'. Thanks to its existence, the difficulty in different areas is able to steadily progress - up to a point, of course - in various ways depending on things such as the world's selected difficulty…
