True Difficulty Scale

Adding True Difficulty Scale to a Forge 1.20.1 instance introduces three new difficulties, named Casual, Expert and Malicious, and each one can be set in a dedicated config file. The config file, named difficultyscaleconfig, controls how much damage the player deals and receives, and it can also change the stats of specific mobs under each difficulty. Entities and items can be locked so they only appear or can be obtained in the difficulty chosen for the world.

Items and entities are tied to difficulties through tags. The tags truedifficultyscale:casual, truedifficultyscale:expert and truedifficultyscale:malicious place an item or entity in that difficulty, while the min variants of the expert tag make it available from Expert upward instead of Expert only. An item or entity can carry only one of these tags, and mods that add content can use the same tags, including for items that sit in a Curios slot.

The mod is released under All rights reserved and is not open source. A server running it needs every connecting player to have it too. Files are published for Forge only, for 1.20.1, with version 1.2.0 as the latest build from 2026-05-09.
