HealthDrain

Fabric mod that lowers your maximum hearts on a timer — for challenge runs, speedrun variants, and manhunt-style multiplayer.

Compatible with Minecraft 26.2 / Fabric Loader 0.19.3 (same stack as recent SpeedRunIGT).

Features

• Reduces max health over time (not just current HP)
• Configurable interval, starting hearts, minimum hearts, and hearts lost per interval
• Half-heart support (e.g. floor at 0.5)
• On-screen countdown: Next heart: M:SS
• Optional chat message + loss sound (Off / Hurt / Anvil / Totem)
• Progress saved per player and kept on death
• Paused singleplayer does not drain
• Target mode for manhunt — only one named player is affected
• In-game config via Mod Menu (Cloth Config is bundled)

Defaults

Dependencies

Required

• Fabric API
• Fabric Loader 0.19.3+
• Java 25+

Optional

• Mod Menu — in-game settings
• SpeedRunIGT — compatible, not required

Singleplayer

1. Install Fabric Loader + Fabric API + this mod (Mod Menu recommended).
2. Open Mods → Health Drain (or edit config/healthdrain.json).
3. Tune interval / hearts / sound as you like.
4. Leave Target mode off for a normal solo challenge.

Multiplayer / manhunt

Drain is decided by the server/host config.

1. Enable Target mode.
2. Set Target player name to the runner’s username.
3. Only that player loses max hearts; everyone else is unaffected.

• LAN / Open to LAN: configure on the host via Mod Menu.
• Dedicated server: edit the server’s config/healthdrain.json (client Mod Menu won’t change the server).

If target mode is on but the name is empty, nobody is drained.

Config

config/healthdrain.json — or Mod Menu tabs: General, Multiplayer, Display, Audio.
