1 HP Challenge
by Robot9
1 HP Challenge lets server administrators drop a chosen player to a single half-heart of maximum health with one command.
What it does
The mod is a server-side hardcore option for multiplayer servers that run custom challenges or extreme survival events. It is disabled by default, so players join and play standard Minecraft until an administrator switches a challenge on for them. A player's reduced health is stored in that player's data, so it carries over through respawns and game restarts.
Commands accept the standard Minecraft target selectors p, s and r and offer tab-completion, so an administrator can target the nearest player or a specific name in one line. Using the commands requires operator permissions or cheats to be enabled. The server needs the mod; players can join without installing anything.
Files are published for Forge only, for Minecraft 1.12.2, with build 1.0.2 dated 2026-05-28 as the latest release. The mod is open source under no license: it is released under All rights reserved.

Instant toggling
The same command sets or restores health, so a challenge can start or end without a restart.
Target selector support
Standard target selectors let an administrator pick the nearest player, a random player or a named one.
Persistent player state
The reduced maximum health is saved to the player's data and survives respawns and restarts.
