1 Heart Challenge
by Kootryne
1 Heart Challenge limits a player's health to a single heart, two hit points, as a server-side minigame.
What it does
Once the mod is active, a player's maximum health is cut to one heart, which is two hit points, so the next hit can end the run. Only the server needs it; players who join a server running the mod do not need to install anything themselves. Singleplayer worlds need the mod installed locally to work the same way. Builds are published for Fabric and NeoForge, covering 1.20.1 – 1.21.11, and the code is not open source, released under Creative Commons Attribution Non Commercial No Derivatives 4.0.
Key features
Single-heart limit
Maximum health is reduced to one heart, so a player starts each run with only two hit points.
Server-side setup
The server runs the limit, and joining players need no additional install on their client.
Singleplayer use
In singleplayer the mod must be installed locally to apply the same one-heart limit.

What the author says
This is a simple mod that limits each players health to only one single heart (2 hp). This mod is only required for the server to have (if you are playing on a server) each of the players does not need it. If you are playing singleplayer you do need to have it installed for it to work of course.
