OneMace

Tired of plugins that claim to fix multiple Maces—but don’t?

OneMace enforces a hard limit: players can have only one Mace. No bypasses. Period.

OneMace introduces a unique gameplay twist by limiting the entire server to a single Mace. No more spamming Maces—strategy and skill are key! Perfect for Lifesteal and competitive PvP servers that want to balance the game.

The plugin stores the crafted state in config.yml, so it remains saved across restarts.
The Mace recipe is re-enabled if the Mace is destroyed (e.g., lava, void, breaking).
Announcements for crafting & destruction can be enabled/disabled in config.yml.

Configuration

settings:
  mace-crafted: false  # Changes to true when the Mace is crafted.
  mace-owner: null  # Stores the UUID of the current owner, or null if no owner.
  announce-mace-messages: true  # If true, broadcasts when the Mace is crafted or lost.
  allow-locate-for-all: false # If true, allows any player to use the '/onemace locate' subcommand.
  colored-name: false # If true, the player that has the Mace will have a colored name.
  mace-name-color: "RED" # The color of the name, use Chat Colors.
  optional-allowed-containers: # Containers that the Mace is allowed to be placed into.
    - ENDER_CHEST
    - ANVIL
    - ENCHANTING

# Stores whether an offline player logged out with the Mace.
# If set to true, the Mace is in their inventory or Ender Chest when they logged out.
# Used to prevent crafting if the Mace still exists in an offline player’s possession.
# This is automatically updated when a player logs out or the server shuts down.
offline_inventory: {}

# Customizable messages
messages:
  crafted: "&b[OneMace] &eThe Mace has been crafted!"
  lost: "&b[OneMace] &eThe Mace has been lost!"

Bypasses & Limitations

⚠️ Maces in unloaded chunks will NOT be detected. This is unfortunately unfixable due to how Minecraft works. It is up to you to detect and use the admin commands if you suspect there may be more than one Mace.

Otherwise, this plugin should work perfectly on a clean vanilla server.
