auto0.5HP
by 7enom
auto0.5HP is a data pack that lowers the player's maximum health by half a heart and applies the change to every player in the world.
What it does
The data pack forcibly reduces each player's HP by 0.5, which raises the difficulty of a world it is loaded into. Once a world is created, the pack has to be loaded there, and the system applies the change to players automatically. Installing data packs or mods in a world works without operator status from version 1.1 onward.
The mod is distributed for Fabric, Forge, NeoForge and Quilt as a data pack. Builds target 1.21 – 1.21.1, with Beta-1.1+mod for 1.21.1 as the latest file. The server is required and the client is optional, and the license is Creative Commons Attribution 4.0, so the mod is not open source.
Key features
Reduced player HP

Automatic application
The change applies to players in the world without manual setup after the pack is loaded.
Data pack loading
The pack can be added to a world after creation, and operators are not needed from version 1.1 on.

What the author says
This data pack may be for advanced users. After adding the world you want to use, enter the /reload command, click the "world" section, and then click the yellow area. The system will then automatically modify the players in that world.
