Thorium Lifesteal Mod

Players gain and lose hearts through PvP. Killing another player steals one heart, and only player-versus-player deaths remove hearts, so deaths from the environment or mobs do not. A player who is eliminated loses hearts until they are out. Players can also craft Thorium Hearts, a recipe built to stay possible during a long SMP, and use them to gain extra hearts. Hearts can be withdrawn as physical items, so players can trade or store them and accept the risk that comes with carrying them.

The mod bundles the systems a Lifesteal SMP normally needs from separate plugins. Teams hold up to 7 players each, admins have draft tools to build them, and teams are saved between sessions. Claimed bases protect chests and blocks, and inside one a team member's locator bar stays hidden. Saved hearts and data survive server restarts, and the tools that help run server events sit in the same mod. With Simple Voice Chat installed, the mod can create voice groups for each team.

Thorium Lifesteal is client and server, so the server and every player need it. It requires Fabric API. Files are published for Fabric only, for Minecraft 26.2, with 2.0.0 as the latest file released 2026-07-21. The mod is all rights reserved and is not open source.
