Daily Heart Loss
by StormLineMC
Daily Heart Loss is a Fabric challenge mod that removes maximum health from players each Minecraft day until only half a heart remains.
What it does
Each time a set number of Minecraft days pass, every player loses one heart of maximum health, and the loss is permanent. The drop continues until a configurable minimum is reached, which defaults to half a heart. Survival therefore gets harder as the world ages, and the amount of health lost per cycle, the length of the cycle and the starting maximum health for new players can all be changed.
Every setting is adjusted in-game with commands, so server owners can tune the challenge without editing files. Heart loss messages can be broadcast to all players or sent only to the players affected, and a command shows any player's health progression. Settings can be reset to their defaults, and a heart-loss event can be triggered immediately for testing.
The mod runs on servers alone, so players join without installing anything. It requires Fabric API and is published for Fabric on Minecraft 1.21.4, with 1.0.0 as the latest file, released under the MIT License. The code is not open source.
Key features
Permanent health loss
Maximum health drops by one heart each cycle and stays lower, so the challenge accumulates over the course of a world.
Adjustable cycle
The number of Minecraft days between losses and the amount lost per cycle are both set with commands.
Minimum and starting health
A floor sets the lowest maximum health players can reach, and a starting value sets the maximum for new players.
Broadcast or private messages
Heart loss notices can go to every player or only to the players who lost health.
Progress tracking and testing
A command shows a player's health history, and a heart-loss event can be applied immediately to check settings.

Use cases
Who it’s for: The mod suits server owners who want a permanent difficulty curve in survival, and players who join such servers. Because only the server needs the mod, players on a shared server do not have to install anything.
How it compares
Half Heart! is a server-side only Fabric mod for 1.21.4 with all rights reserved, so it is not open source. Lifesteal, published by Pyric, is server required with client optional, covers 1.21.4 – 1.21.8 and is open source under the MIT License. XP Health is server-side only, open source under the MIT License and built for 1.21.1, so it targets an older version.
