Limited Mace

A simple Fabric mod that allows only one Mace to be crafted per world.
Once a player crafts the first Mace, all further crafting attempts (including automated crafters) are blocked.

Features

• Prevents mass-crafting with shift-click.
• Compatible with automated crafters.
• /limitedmace reset command to allow crafting a new Mace.
• /limitedmace state command to check if the first Mace has been crafted.

Usage

1. Install Fabric API for Minecraft 1.21.8.
2. Place the mod .jar file into your server's mods/ folder.
3. The first Mace crafted in the world will be allowed — all others are blocked until reset with command.

Credits

I did not invent the Mace concept — it is an official Minecraft item by Mojang. This mod simply enforces a "one per world" rule, like other plugins do, using the Fabric modding API.
