| Environment | Client, Server |
AttributeFix is a Fabric, Forge, NeoForge, and Quilt mod by Darkhax that raises Minecraft's built-in caps on attributes such as armor, attack damage, and max health. Vanilla hard-limits these values (armor tops out at 30 points, for example), so gear and other mods that push past that ceiling get silently truncated. AttributeFix does not add new stats or rebalance anything itself; it just removes the artificial limits so the numbers other mods calculate actually apply. It runs on both the client and the server.
What the attribute cap bug actually is
Minecraft's attribute system drives calculations like armor value, attack damage, and movement speed, and Mojang hard-codes a ceiling on many of these values. Vanilla armor, for instance, cannot exceed 30 points no matter how much a piece of gear or an enchantment tries to add. A player wearing enchanted or modded armor that should total more than 30 armor points simply loses everything above the cap, with no warning and no error. AttributeFix raises these limits to a wide, sane range so a mod's intended values stop getting clipped.
Supported loaders and Minecraft versions
AttributeFix ships separate builds per loader, and they are not all on the same version. Fabric and NeoForge both reach the current 26.2 release; Quilt stops at 1.21.11; Forge has not moved past 1.21.1 since October 2024, aside from a 1.20.1 backport released in February 2026.
- Fabric: up to 26.2 (build 26.2.0.1)
- NeoForge: up to 26.2 (build 26.2.0.1)
- Quilt: up to 1.21.11 (build 21.11.1, February 2026)
- Forge: up to 1.21.1 (build 21.1.2, October 2024), plus a later 1.20.1 backport
Installation
AttributeFix installs the same way as any other loader-installed jar: download the build matching your loader and Minecraft version from Modrinth, then drop it into the mods folder. Follow our Fabric install guide or our Forge and NeoForge install guide first if the loader itself is not set up yet, and see how to install mods on Minecraft Java for the general steps.
Dependencies and compatibility
On Fabric and Quilt, AttributeFix requires Fabric API and Darkhax's own Prickle configuration library, both listed as hard dependencies on its Modrinth page. AttributeFix does not touch any individual mob's or player's attribute values on its own. It only lifts the ceiling, so it is typically installed alongside another mod, or a modpack, that actually pushes armor, health, or damage past vanilla's limits.
What AttributeFix does not cover
- Does not change the vanilla damage formula, which maxes out around 25 armor even though the cap allows 30
- Does not update the in-game armor HUD, which still stops showing points past 20
- Does not modify any specific mob, item, or player's attribute values by itself
Questions about AttributeFix.
5 questions
What does AttributeFix do?
AttributeFix removes Minecraft's artificial caps on attributes like armor, attack damage, and max health. Vanilla hard-limits these values, for example armor stops at 30 points regardless of gear, so anything a mod adds past that ceiling is silently discarded. AttributeFix raises the limits so those higher values actually apply, without changing any specific mob or item on its own.
How do I install AttributeFix?
Download the build matching your loader (Fabric, Forge, NeoForge, or Quilt) and Minecraft version from Modrinth, then place the jar in your mods folder alongside its required dependencies. Fabric and Quilt builds also need Fabric API and Prickle installed, or the mod will fail to load.
Does AttributeFix work with Fabric, Forge, NeoForge, and Quilt?
Yes, but the loaders are not on the same version. Fabric and NeoForge both reach the current 26.2 release, Quilt tops out at 1.21.11, and Forge has not advanced past 1.21.1 since October 2024 aside from a 1.20.1 backport. Check the build list for your loader before downloading.
Why does higher armor not block more damage after installing AttributeFix?
AttributeFix only raises the attribute cap itself. Vanilla's damage formula maxes out around 25 armor and the HUD stops displaying past 20, regardless of the higher cap. Getting the combat math and HUD to reflect higher totals needs a separate mod built on top of AttributeFix.
Is AttributeFix safe to use?
AttributeFix is licensed LGPL-2.1-only and distributed through Modrinth, GitHub, and CurseForge by its creator Darkhax. It has over 21.5 million downloads on Modrinth alone. As with any mod, download it only from an official source page rather than a third-party rehost.
