Lifesteal Plugin for Minecraft 1.21.4 (Fabric)

This Lifesteal plugin brings a fully customizable and competitive PvP system to Minecraft 1.21.4 using Fabric. Designed to emulate the intense, high-stakes mechanics of the original Lifesteal SMP servers, this plugin includes heart-stealing PvP, a heart crafting system, unique weapons, and built-in server balance tools.

Core Features

Heart Stealing Mechanic

When a player kills another player, they gain +1 permanent max heart (up to a cap of 20 hearts).
The victim loses 1 max heart upon death.
When a player reaches 0 hearts, they are automatically banned or switched to spectator mode (configurable).
Deaths by non-player causes (e.g. mobs, lava, fall damage) also reduce max health (optional via config).

Heart Cap System

The plugin caps the number of max hearts a player can have to 20.
Hearts above this cap can still be crafted and stored but won’t raise max HP.

Craftable Hearts

Players can craft hearts using rare resources.
When used, crafted hearts restore 1 lost max heart.
Heart crafting recipes can be configured in the mod's settings or turned off completely.

Custom Item: Mace of Slowness

A special weapon with unique PvP utility.
Built as a mid-to-late game item.
Applies Knockback II and Slowness II to enemies on hit.
Can be crafted or given as a custom loot drop depending on server setup.
Works best for juggernaut-style PvP builds or combos.
Optional: Add cooldown or durability balance through config.

Visual & UI Features (Resource Pack Integration)

Potion HUD Display

Timer shows how long active potion effects will last.
Numbers turn red when under 10 seconds remaining.
Styled to be clear and competitive — designed like Wemmbu’s layout.

Armor & Tool Durability HUD

Shows remaining durability of equipped armor and held tools.
Simple, clean display — similar to Wemmbu's style.
Ensures players are always aware of gear integrity during fights.

Custom Particles & Animations

Purple crit particles with a deep, magical look.
On slashing attacks, a fiery slash trail appears (inspired by FlameFrags’ style).
Fully compatible with Fabric and Feather Client.

Animated Fire Cape

Cosmetic cape included in the pack, animated with a flickering flame effect.
Designed to give your player a powerful aesthetic presence.
Optional and non-intrusive — can be toggled in the pack.

Custom Sword and Axe Textures

Styled after ManepEAR’s 100k PvP pack, but with a fantasy twist.
Clean, sharp, and visually satisfying weapons for high-PvP environments.

Still functions the same way unless totems are disabled on the server.
