Summary

Mobs Properties Randomness lets you add/change many properties to mobs on spawn, and, with events, when other stuff happens, such as on attack, on tick or on death with data packs.

This mod requires InsaneLib

As of 5.0.0 and up the mod (and its dependencies) now work server side only, so with MPR server you can connect with a vanilla client.

The mod

The mod does nothing on its own, you have to make a data pack: click here to get started (please note this is for latest version, click here for a list of versions)
You can also find a video tutorial playlist below.

Some stuff you can do:

Potion Effects
Attribute Modifiers
Equipment
Effect immunity
NBT
Events (attack, kill, target change)
Presets (for creating stuff like bosses)

6.1.1.0-betaБета1.21.1 · 18 июня 2026 г.

6.1.1.0-beta

Changed some fields for Potion effects
- hide_particles -> show_particles: defaults to true now
- Added show_icon: defaults to true
Fixed attribute modifiers erroring (failing to spawn the mob) if a modifier with the same id is already applied

6.1.0.0-alpha

BREAKING CHANGES Please read carefully

More presets!

PLEASE NOTE that mobs presets now live in data/mobs_properties_randomness/presets/mobs/ instead of data/mobs_properties_randomness/presets/.
This version introduces modifiers, conditions and functions presets.
These are used if you have multiple conditions, modifiers and functions that repeat, and instead you can write once and reference.

Example, you want to apply a global difficulty scaling modifier to many attribute values, but this is repetitive

[
{
    "property": "attribute_modifier",
    "attribute": "minecraft:generic.max_health",
    "id": "ns:bonus_health",
    "amount": {
        "value": 1,
        "modifiers": [
            {
                "modifier": "difficulty", 
                "operation": "multiply", 
                "easy": 0.75, 
                "hard": 1.5 
            }
        ]
    },
    "operation": "add_multiplied_base"
},
{
    "property": "attribute_modifier",
    "attribute": "minecraft:generic.movement_speed",
    "id": "ns:movement_speed",
    "amount": {
        "value": 0.10,
        "modifiers": [
            { 
                "modifier": "difficulty", 
                "operation": "multiply", 
                "easy": 0.75, 
                "hard": 1.5 
            }
        ]
    },
    "operation": "add_multiplied_base"
}
]

To avoid all this redundancy, you can use a modifier preset. in data/ns/presets/modifiers/difficulty_scaling.json. A modifier preset can contain as many modifiers as you want.

[
    { "modifier": "difficulty", "operation": "multiply", "easy": 0.75, "hard": 1.5 }
]

So the properties can become

[
{
    "property": "attribute_modifier",
    "attribute": "minecraft:generic.max_health",
    "id": "ns:bonus_health",
    "amount": {
        "value": 1,
        "modifiers": [
            { "preset": "ns:difficulty_scaling" }
        ]
    },
    "operation": "add_multiplied_base"
},
{
    "property": "attribute_modifier",
    "attribute": "minecraft:generic.movement_speed",
    "id": "ns:movement_speed",
    "amount": {
        "value": 0.10,
        "modifiers": [
            { "preset": "ns:difficulty_scaling" }
        ]
    },
    "operation": "add_multiplied_base"
}
]

This is a quite easy example, but another real example is:
This is something that will heavily benefit from using presets.

Fixed summoning via /mpr command applying presets 5 times

6.0.1.3

Fixed multiple boss bars flickering

6.0.1.2-beta

Update to latest InsaneLib

6.0.1.1-beta

Update to latest InsaneLib

6.0.1.0-beta

Added set_component item function

You can set whatever data component you want on an item. The following example from the example data pack will make the target equip an iron ingot that can be eaten and used as a pickaxe. Numeric values can be replaced with #range object to generate random values.

{
  "property": "equipment",
  "slot": "offhand",
  "items": [
    {
      "item": "minecraft:iron_ingot",
      "functions": [
        {
          "function": "set_component",
          "components": {
            "minecraft:food": {
              "nutrition": {"#range": {"min": 2, "max": 6}},
              "saturation": {"#range": 0.5}
            },
            "minecraft:tool": {
              "rules": [
                {
                  "blocks": "#mineable/pickaxe",
                  "speed": 6,
                  "correct_for_drops": true
                }
              ]
            },
            "minecraft:max_damage": 453,
            "minecraft:damage": 0
          }
        },
        {
          "function": "set_drop_chance",
          "drop_chance": 2
        }
      ]
    }
  ]
}

6.0.0.0-alpha

Ported to 1.21.1

Mod support will be added back in the future. Let's see how this goes first.
I've also updated the Example Data Pack which was broken in 1.20.1 too. The only difference between 1.20.1 and 1.21.1 are attribute modifier operations.

Missing

Set (Raw) NBT for items
Scaling (pehkui is no longer needed (and seems to no longer work?) as scaling is now an attribute)
Serene Seasons support
Game stages (hasn't updated past 1.20.3)
