Half Heart!
by unkn0kable
Half Heart! is a Fabric minigame that permanently caps player health at half a heart, turning every hit into a possible death.
What it does
Under the mod, a player's health is locked at 0.5 hearts, so any mistake can end the run. Healing from food or potions does not raise the cap, and only other mods or cheats that increase health get around it. The challenge applies across game modes, including Survival and Hardcore, which makes encounters with mobs, bosses and environmental hazards much more tense.
The mod is built around careful planning: boss fights, falls and other hazards are designed so that a single misstep is fatal. It is aimed at players who want to test patience, skill and strategy in a deliberately unforgiving form of survival.
Half Heart! is a server-side only mod, so clients need nothing installed. It is published for Fabric and targets 1.21.4 only. The code is not open source; the license is All rights reserved, though source code is publicly available.
Key features
Permanent half-heart health
Maximum health is locked at 0.5 hearts for the whole run, so the first mistake usually ends the game.
Healing blocked
Food and potions do not restore health beyond the cap, so recovery depends on avoiding damage in the first place.
Hazards and bosses
Mobs, boss fights and environmental hazards are tuned for a fragile character, forcing players to plan each move.
Works across game modes
The challenge applies in Survival and Hardcore alike, so existing worlds and modes can be played under the same rule.
