Difficulty Tweak
by NyxYoru
Difficulty Tweak raises the stats of mobs on a server, adding a difficulty layer on top of vanilla Minecraft for Fabric players.
What it does
The mod increases mob damage, movement speed and health directly, so enemies and allied mobs are tougher without changing the standard gameplay rules. Three difficulty levels are offered: one raises mob damage and move speed by 20% and health by 50%, a second raises them by 40% and 100%, and the third by 60% and 150%. A difficulty change is made through a function, and standard Minecraft gameplay is kept, with no other effects added on top of the stat changes.
The mod is server-side only, so the server runs it alone and players join without installing anything. Buffs for certain ranged enemies depend on Projectile Damage Attribute, which is a required dependency and must be installed next to this mod. Eleven release versions are published for Fabric, and the 1.19 and 1.20 older builds are listed but untested.
Key features
Mob stat scaling
Mob damage, movement speed and health are raised by a fixed percentage at each difficulty level.
Three difficulty levels
Each level sets a different scale, from +20% damage and speed with +50% health up to +60% and +150%.
Ranged enemy buffs
Certain ranged mobs receive extra damage through the Projectile Damage Attribute, which the mod depends on.
Standard gameplay kept
Stat changes are the only effect, so vanilla mechanics and item behavior stay as they are.

How it compares
Bossmode is also server-side only, open source under the MIT License and published for Fabric 1.20.1 – 1.20.6, so it covers a different version range than Difficulty Tweak. Mob Difficulty RPG is a client and server mod with All rights reserved licensing, not open source, and it is listed for Fabric 1.20.1 only. Majrusz's Progressive Difficulty runs on client and server, is open source under the MIT License and covers 1.18.2 – 1.20.1 across Fabric, Forge, NeoForge and Quilt.
