Lifesteal
Minigame of the lifesteal. When you kill a player you will steal one-half of their lifebar
About this Mod
Lifesteal adds a thrilling new mechanic to Minecraft survival and PvP worlds.
With this datapack, every battle truly matters — because when you kill another player, you steal half a heart from their maximum health.
⚔️ How it works
Whenever a player dies at your hands, you permanently gain +0.5 hearts.
The defeated player permanently loses the same amount.
Over time, strong players become stronger, while others must fight to regain their lost hearts.
🌍 Perfect for multiplayer
Whether you’re running a small friends’ world or a public PvP server, Lifesteal fits seamlessly.
It’s easy to install, lightweight, and fully compatible with the latest Minecraft versions.
🔥 Challenge your limits
Grow stronger with each kill, defend your hard-earned hearts, and rise to become the most powerful survivor.
But beware — one mistake could cost you everything.
Only the strongest will survive in the world of Lifesteal.
