AttributeFix Mod (1.21.10, 1.20.1) – Removes Arbitrary Limits

AttributeFix Mod (1.21.10, 1.20.1) is a Minecraft mod that removes or extends the arbitrary limits imposed by Mojang on the attribute system. Attributes control values such as max health, movement speed, and attack damage for entities. In vanilla Minecraft, these values are capped (for example, maximum health and attack damage are limited to 1024). This causes many mods to behave incorrectly when using higher numbers. AttributeFix raises these limits so that large or extreme attribute values work properly.

Features:

• Removes vanilla attribute caps such as max health, attack damage, and armor.
• Automatically applies the fix when the mod is installed, with no extra setup.
• Configurable through a JSON file where each attribute can have its own limits.
• Compatible with other mods — you can enable or disable patching per attribute to avoid conflicts.
• Does not modify combat formulas or HUD; it only adjusts attribute limits. Other mods are required to change those behaviors.

Example Issues:

Without AttributeFix, you may see the following problems:

• Max health is capped at 1024. A mob with 10,000 HP will effectively have only 1024 HP.
• Attack damage is also capped at 1024. A sword with 5,000 attack damage will only deal 1024 damage.
• Armor values above the vanilla cap (around 30) may not apply correctly.

Test example:

/give @a golden_sword{AttributeModifiers:[{AttributeName:"generic.attack_damage",Amount:5000,Slot:mainhand,Name:"generic.attack_damage",UUID:[I;-12454,17070,183450,-34140]}]}

/summon spider ~ ~ ~ {Health:10000,Attributes:[{Name:"generic.max_health",Base:10000f}]}

In vanilla Minecraft, the mob would die in a single hit because damage is capped.
With AttributeFix, it behaves as expected — higher damage values and large health pools work correctly.

Configuration

The mod creates a file called attributefix.json inside the config folder.
This file contains limits for each attribute.
It is generated automatically the first time you run Minecraft with the mod installed.

Example entry:

{
  "minecraft:generic.max_health": {
    "enabled": true,
    "min": {
      "default": 1,
      "value": 1
    },
    "max": {
      "default": 1024,
      "value": 1000000
    }
  }
}

Explanation:

• enabled: If true, AttributeFix will apply the new min/max limits to this attribute.
• min: Minimum allowed value. default shows the vanilla limit; value is the active value.
• max: Maximum allowed value. default shows the vanilla cap; value is your new desired limit.

Most vanilla attributes are enabled by default.
Attributes from other mods are disabled by default to prevent conflicts, but you can enable them manually if needed.

FAQ

Does AttributeFix directly change player or mob stats?
No. It only removes the numeric limits.
To change a player or mob’s health, damage, or speed, you still need commands or another mod.

Why doesn’t higher armor reduce more damage?
Because Minecraft’s combat formula has its own saturation limit.
Even with higher armor attributes, the vanilla formula may stop providing extra protection.
AttributeFix only allows higher numbers — it doesn’t change how damage is calculated.

Why doesn’t the HUD show more armor icons?
The HUD has its own display limit.
Changing attribute caps won’t affect the number of armor icons shown on screen.

Where is the config file?
In your Minecraft directory, under config/attributefix.json.

Can I disable certain attributes?
Yes. Set “enabled”: false for any attribute you want to exclude from patching.
