Immortality

Immortality is a server-side Fabric mod for players who want an operator to decide who can survive fatal damage. Immortal players still take damage, but the mod steps in before a hit would kill them and leaves them at half a heart. Totems of Undying keep their normal behavior, so a player can still be saved by one as usual. Players do not need the mod, and the mod does not change how death works for anyone who has no grant.

Administration runs through a single root command, immortal, which accepts Minecraft selectors such as @p where they apply. A grant can be permanent or last a set duration with supported time units, and a value of false revokes it. The server console can run the same commands, and the mod relies on Minecraft's built-in operator permissions, so only operators can use them. A game rule named immortal toggles the feature server-wide and can change the supported settings. Grants and configuration are saved automatically, and the mod can show expiration and notify players.

The mod is published for Fabric and Paper across game versions 1.20 – 26.3, with 22 release versions. The latest Fabric file is 2.0.0+26.3 for 26.3, released 2026-10-10.
