Advanced Mobs
by AraXer
Advanced Mobs replaces some vanilla mobs with elite versions whose strength grows with the difficulty setting, so zombies, skeletons and blazes become harder enemies on Forge for 1.20.1.
What it does
The mod adds no new creatures. Instead it swaps some classic Minecraft mobs for rarer, more dangerous variants with custom textures and behavior. Elite zombies, skeletons and blazes appear in the world, and the more difficult the game is set, the stronger these versions become, so a player can choose how tough the enemies get.
Scaling and spawning are adjustable. The config file controls how the difficulty scaling and spawn behavior work, and datapacks can change loot and spawn behavior further. The mod also adds deeper, darker versions of the familiar mob sounds and custom spawn eggs that let creative players summon the elite variants directly.
Advanced Mobs is published for Forge only, for Minecraft 1.20.1, and runs on client and server, so the server and every player need it. The latest Forge file is 1.2.3, released on 2025-09-08. The code is all rights reserved and the project is not open source.
Key features
Elite mob variants
Rare, dangerous versions of zombies, skeletons and blazes replace the vanilla mobs in some spawns.
Difficulty-based scaling
Elite mobs grow stronger as the difficulty setting rises, and the scaling can be tuned in the config.
Custom spawn eggs
Spawn eggs for the elite variants let creative players place them directly in a world.
Darker mob sounds
The familiar growls and hisses of the replaced mobs are kept, with a darker twist.

Use cases
Harder hard mode
Players who want a tougher survival game can raise the difficulty and rely on the elite versions to scale the challenge.
Staged progression packs
Modpacks with staged survival can use the datapack hooks for loot and spawn behavior to match each stage.
Who it’s for: Players who find vanilla mobs too mild and server owners who want a difficulty-scaled enemy set without new creatures. Modpack makers can use the config and datapacks to control spawning and loot.
How it compares
Crying Skeleton is a Forge mod for 1.20.1 – 1.21.8 that runs on client and server and is all rights reserved, so it covers a wider version range. No Skeletons is a Forge mod for 1.20.1 that is server-side only, so players join without installing it. Advanced Mobs covers only 1.20.1 and needs both sides.
