Overview

AttributeFix is a lightweight but essential mod designed to address a fundamental limitation in Minecraft's engine. While the game's attribute system is theoretically flexible, Mojang implemented "arbitrary limits" on many core properties. These caps often prevent high-tier modded gear, powerful RPG-style bosses, and custom progression systems from functioning as intended.

For example, in vanilla Minecraft, a mob's maximum health is capped at 1,024. If another mod attempts to create a boss with 10,000 HP, the engine will silently truncate that value to 1,024, making the boss significantly weaker than intended. AttributeFix solves this by intercepting the attribute registration process and significantly increasing these maximum limits to a practical, near-infinite range.

Frequently asked questions

Where do I find the config file for attributefix?

The config file is called attributefix.json and is located in your config folder. It's generated automatically the first time you run Minecraft with the mod installed.

How do I increase max health above 1024?

Open attributefix.json, find the "minecraft:generic.max_health" entry, and change the "value" under "max" to your desired limit. Save the file and restart Minecraft for changes to take effect.

Why is my custom mob still dying too fast?

AttributeFix only removes numeric limits—it doesn't change how damage is calculated. Make sure you're actually setting the mob's health value high enough using commands or NBT data, not just enabling the mod.

Do I need to enable attributes from other mods?

Attributes from other mods are disabled by default to prevent conflicts. You only need to enable them in attributefix.json if another mod isn't working correctly with high attribute values.
