Life Steal

A Fabric mod that brings the iconic LifeSteal SMP mechanics to Minecraft 1.21.11.

⚔️ What is LifeSteal?

Inspired by the popular LifeSteal SMP created by Minecraft content creators, this mod adds a permanent heart-stealing mechanic to your game.

When you kill another player, you steal one of their hearts permanently. When you are killed, you lose one heart forever.

The stakes are high — lose all your hearts, and you become a spectator, watching the world go on without you.

✨ Features

• 💓 Permanent Heart Stealing — Every player kill grants you +1 heart (up to 20 total). Every death costs you -1 heart.
• 👻 Spectator Mode on 0 Hearts — Lose all your hearts and you're out — forced into spectator mode.
• 💾 Persistent Player Data — Hearts are saved per-player in config/life-steal.json. Never lose progress on server restarts.
• 🚫 Hardcore Compatibility — Automatically disables itself in Hardcore mode to preserve vanilla experience.
• 🛡️ Server-Side Logic — Core mechanics run entirely on the server. Client installation is optional but recommended.
• ⚙️ Admin Commands — Full control over player hearts with the /heart command.
