Custom Mob Attributes
by Fneifnox
Custom Mob Attributes lets server owners and players change how strong individual mob types are, by scaling their vanilla health, attack damage, movement speed and size through multipliers.
What it does
Each mob can be configured on its own, including baby variants, and the values apply to mobs that are already spawned as well as new ones. Projectiles fired by mobs are affected too, so an arrow from a skeleton can be made stronger or weaker through the same settings. Changes made in-game take effect after the game is restarted or the world is rejoined.
The mod is aimed at anyone who wants tougher or gentler encounters without writing a datapack. It needs Fabric API and oωo (owo-lib) on every loader, and Mod Menu is optional but recommended for opening its settings screen. The mod runs on the client and the server, so both sides need it. It is published for Fabric, Forge and Quilt across 24 release versions, 1.20 – 26.3, under a custom license, and it is not open source.
Key features
Per-mob values
Health, attack damage, movement speed and scale can be set separately for each mob type.
Multiplier-based settings
Values are multipliers that scale the vanilla numbers rather than replacing them.
Projectile adjustments
Projectiles shot by mobs, such as skeleton arrows, can be configured alongside the mobs that fire them.
Live updates for spawned mobs
Changing a value applies to mobs that have already spawned, not only to those that appear later.

Use cases
Harder or easier play
A server can raise the strength of hostile mobs for a challenge run or lower it for a relaxed world.
Baby mob tuning
Baby variants have their own entries, so their stats can differ from the adult form of the same mob.
Who it’s for: Server owners who want to adjust mob difficulty and players running single-player worlds who prefer tougher or gentler encounters.
