Causes mobs to spawn with randomly weaker or stronger health, attack damage, or speed stats within configurable ranges.

Also lets you scale the aforementioned stats by a customisable value based on the biome the entity was spawned in (e.g. all mobs spawned in the desert can have 2x health), and lets you blacklist entities from having any stat changes from this mod at all.

Basic Stat Functionality

On spawn, an entity has a 50/50 chance to either have a stat increase or decrease for a given stat, where an increase will calculate as so: new_stat = old_stat x (1+stat_increase/100), and a stat decrease will calculate as: new_stat = old_stat x (1-stat_decrease/100).

This will apply the same way with stat changes from other mods, though the order of stat changes applying is undetermined.

Entity Blacklisting

You can blacklist an entity from having stat changes from this mod by passing in the entity type id (e.g. "minecraft:zombie"), or a tag the entity is a part of with a hashtag at the front (e.g. "#minecraft:raiders"), note the quotation marks around entities are needed in the config.

Biome Modifiers

For health, damage or speed stats individually, you can give a modifier based on the biome that the entity was spawned, modifying the overall attribute as so: new_stat = old_stat x (1 + stat_change), biomes can be specified by biome id (e.g. "minecraft:desert=2"), or by biome tag (e.g. "#minecraft:is_ocean=-0.5"), where after the biome the value should be specified with "=value" within the same quotation marks.
