Mining Fatigue Reproduction

Bringing mining fatigue back to reason — linear slowdown, no exponential explosion, saving your mouse and your patience.

📖 Introduction

In vanilla Minecraft, the Mining Fatigue effect decreases mining speed exponentially with each level:

Level I: speed × 0.3 (3.33× slower)
Level II: speed × 0.09 (11× slower)
Level III: speed × 0.027 (37× slower)
Higher levels make blocks nearly unbreakable, especially in Ocean Monuments where multiple Guardian attacks stack the effect and completely ruin the mining experience.

This mod changes Mining Fatigue to a linear slowdown: each level reduces your speed by only one additional factor.

No more exponential nightmare — smooth, predictable, and still threatening.

Linear scaling: Speed = original speed ÷ (level + 1). Higher levels are slower, but never drop to zero instantly.
Cap protection: Configurable maximum slowdown divisor (default 10) to prevent excessively high levels from making mining virtually impossible.
Vanilla compatible: Efficiency enchantments and Haste effects still counter the slowdown normally; milk clears the effect.
Pure & clean: Only changes mining speed — movement speed, attack speed, potion duration, and all other attributes remain untouched.
Lightweight: No extra dependencies; drop in and play.

✅ Ocean Monuments are no longer “no-mining zones” — even with stacked Mining Fatigue, you can still break blocks slowly but steadily.
✅ The breaking progress bar never freezes; every hit gives feedback, making the game feel responsive.
✅ High-level fatigue is no longer a death sentence — you still have a chance to act, just slower.
✅ Perfect for survival, building, and exploration — improves experience without breaking balance.

Configuration file: config/miningfatigue_reproduction-common.toml
- maxDivisor: Maximum slowdown factor (default 10). Levels beyond this won't slow you further.
In-game command (requires operator permissions):
- /miningfatigue setMaxDivisor <number> – change the cap on the fly.

Minecraft 1.20.1, Forge 47.x.
Should work with all 1.20.x sub‑versions (tested on 1.20.1).
No known conflicts with OptiFine, Sodium, or other mods (only listens to break‑speed events).
