MobLevelScale — Mod Summary

Minecraft 1.20.1 | Forge 47.4.20 | Mine and Slash Addon

Overview

MobLevelScale is a lightweight Forge mod that solves one of the most immersion-breaking issues in Mine and Slash modpacks: enemies spawning far below the player's level. No matter how far you progress, weak mobs keep appearing and cluttering the world. MobLevelScale guarantees that every mob spawns at or above the nearest player's level, making the world feel consistently challenging.

The Problem

Mine and Slash assigns mob levels based on dimension config ranges and a variance value. This means a level 80 player can still encounter level 10 zombies wandering nearby. It breaks immersion, wastes time, and makes the early-game mobs feel pointless at higher levels.

How It Works

MobLevelScale listens for mob spawn events at the lowest possible priority, ensuring it runs after Mine and Slash has already assigned the mob's level. If the assigned level is below the nearest player's level, the mod corrects it upward using Mine and Slash's own capability system.
