Immortal
UnstableSmp is a simple “immortal toggle” plugin for Scripted SMP's and event servers. It allows server admins to mark specific players as immortal, meaning they can take normal damage but will never drop below a configurable minimum health value (default: half a heart).
Features
- Toggle immortality for individual players
- Players take normal damage until the minimum health is reached
- Prevents death by reducing fatal damage instead of cancelling it
- Fully compatible with Totems of Undying (vanilla behavior)
- Lightweight, no unnecessary mechanics
- Player immortality is saved and persists across restarts
- Simple and customizable configuration
