Apply Different Mob Sizes Based on Minecraft Difficulty

Use difficulty-based scaling

Configure mobs to spawn at different sizes depending on whether the world is set to Peaceful, Easy, Normal, or Hard. This automatically adjusts mob challenge as difficulty changes.

`

/mobscalings set <entity_type> difficulty {peaceful:1.3, easy:1.15, normal:1.0, hard:0.75}

`

In this example, Peaceful spawns the largest mobs (1.3×), while Hard spawns the smallest (0.75×).

Invert for harder gameplay

If you want difficulty to make mobs *bigger* and tougher, reverse the numbers:

`

{peaceful:0.75, easy:1.0, normal:1.15, hard:1.3}

`

Combine with attribute scaling

You can also add scale_health and scale_damage to difficulty configs:

`

/mobscalings set <entity_type> difficulty {peaceful:1.3, easy:1.15, normal:1.0, hard:0.75, scale_health:"normal", scale_damage:"normal"}

`

Reload to apply changes

After setting your difficulty config, run /random_mob_sizes config reload to activate it in your running world.
