About this Mod

Random Size Mobs

Features:

True Scale Randomization: Mobs no longer spawn with fixed size presets. Enjoy a smooth distribution from 0.15x to 8.0x.
Dynamic Attributes: Health and Attack Damage scale automatically based on the mob's size.
Creeper Scaling: Explosion radius is now tied to the Creeper's size.
Combat Growth: Mobs grow slightly when dealing damage, making long fights more dangerous.
Loot Scaling: Bigger enemies drop more items (extra loot rolls).
Feeding Mechanics: Breeding or healing animals increases their size.

Technical:

Server-side only (Vanilla clients can join).
No dead zones in size distribution (0.3, 0.5, 0.9, etc., are all possible).
