AntiMaceKill | Blocks mace kill exploit v1.2

A lightweight, high-performance plugin designed to block Mace damage exploit.

Advanced mitigation for Mace exploits and packet spoofing.

With the 1.21 update, the Mace introduced a new vulnerability: Packet Spoofing. Cheaters can trick the server into thinking they've fallen from massive heights to deal thousands of damage in a single hit. AntiMaceKill bridges this gap by validating player physics in real-time.

Core Features

  • Apex Tracking: Tracks the player's true peak height (Apex Y) to ensure they cannot spoof fall distance while mid-air or using Wind Charges.
  • Impossible Fall Check: Detects and flags players claiming to fall large distances within a single tick.
  • Configurable Damage Cap: Set a hard limit (default: 15.0 hearts) to prevent "one-tapping" players in maxed gear, regardless of fall height.
  • Staff Alerts: Clean, hoverable in-game alerts and Discord Webhookintegration with Hex color support.
