1 HP Challenge

Half Heart Challenge is a lightweight, server-side friendly hardcore mod designed for custom challenges, multiplayer events, or extreme survival playthroughs. By default, the mod is completely disabled, allowing players to enjoy a standard Minecraft experience upon joining.

However, server administrators can instantly trigger the hard mode for any player using a set of flexible commands and target selectors. When activated, the chosen player’s maximum health drops to a single half-heart (1 HP). This state is saved directly into the player’s data, meaning it will persist even after respawning or restarting the game.

Available Commands (Requires OP/Cheats):

• /1hp @s on — Enable 1 hp challenge for yourself.
• /1hp @a off — Disable the challenge and restore standard health for everyone.
• /1hp <player_name> on — Instantly set a specific player’s health to half a heart.
• /1hp @p off — Restore normal health for the nearest player.

The mod fully supports standard Minecraft target selectors (@a, @p, @s, @r) and features handy Tab-completion for fast typing in the chat!
