Only One Heart
by passo
With Only One Heart installed, a player's base maximum health is cut to one heart, and the server can switch it to a half-heart limit instead.
What it does
Only One Heart is a Fabric mod for Minecraft Java Edition 26.2 that lowers the base maximum health to one heart, turning each session into a challenge run. A default One Heart mode is available, along with an optional Half Heart mode. A third setting, Off, returns the health display to vanilla behavior without removing the mod from the game. The mod can be turned off and on in the same session, and the chosen mode is stored in its configuration and kept between sessions.
The mod works in Survival, Creative, Spectator and Hardcore, and the modes are selected with commands that work in singleplayer without enabling cheats. Every player and the server need a copy of the mod. Mod Menu is optional and can be used to change the settings from a screen. The mod is open source under the MIT License and is published for 26.2 only, with version 0.2.0 as the latest Fabric file.
Key features
One Heart limit
Caps the player's base maximum health at one heart, the default mode of the mod.
Half Heart option
An optional mode lowers the base limit to half a heart for a harder run.
Steady last heart
The remaining heart stays still instead of shaking at low health, which removes the low-health bounce.
Health sources still work
Absorption hearts and golden apples keep working, and Temporary Health Boost or other max-health modifiers add health above the selected limit.
Mode commands
Modes are picked with commands, and the chosen mode is saved in the configuration and kept between sessions.
