AttributesFix

The mod changes the underlying attribute system so that the built-in ceilings and floors for each attribute are expanded. Once it is installed, values set through commands, datapacks or other mods are no longer clamped at the vanilla limits. The attribute limits are adjusted automatically, and no further configuration is required unless a server owner wants to customize the limits.

The mod does not alter vanilla gameplay on its own. It expands the range of possible values, so mods and custom setups that rely on higher attribute values can use them. Expanding a limit does change the mechanics that read the attribute: the vanilla damage formula caps armor effectiveness around 25 even though the attribute can reach 30, and the armor bar in the HUD shows only up to 20 points. Reading those values differently takes extra mods.

AttributesFix is a NeoForge mod for Minecraft 1.21 and 1.21.1, with its first release, 1.0.0 for 1.21.1, published on 2024-08-17. It is installed on both the client and the server, so both need it. The code is released under the MIT License and is not open source. The mod is inspired by the original AttributeFix and was built from the ground up, so it does not reuse that code.
