Mob Scaling
by Tobindog100
Mob Scaling makes hostile mobs gain stronger gear, effects and health as a player advances through the game, from iron and diamond milestones to the defeat of the Ender Dragon.
What it does
Mobs are upgraded when a player reaches set milestones. After obtaining iron, mobs can receive leather armour, with a 50% chance of a wooden sword upgrade. Diamonds give mobs speed and fire resistance II, with a 2 in 3 chance of a leather to chainmail armour upgrade and a 50% chance of a stone sword. Entering the Nether can grant regeneration and an iron upgrade, while finding a stronghold lets spawning wither skeletons gain slow falling, resistance and weaving chances.
Each milestone is tied to an advancement the game checks on a tick. Mobs within 100 blocks of the player gain the effects, and zombies that hit a player can apply poison. Beyond the dragon fight, the mod is intended to keep mobs threatening even with maximum gear.
Mob Scaling is a Forge and NeoForge mod for 1.20.1 and 1.21.8, with files for each loader. The server and every player need the mod installed. Mob Scaling is released under All rights reserved and is not open source.
