Minecraft Custom Mace Plugin

Job ID: 40021447

Budget: $10 – $30 USD

I run a Minecraft server and want to add a brand-new weapon called the Dragon Mace. The key behaviour is simple but unique: any player who merely keeps the mace anywhere in their inventory should receive a continuous Strength I effect, and the moment they right-click with it, the mace launches a dragon fireball. That projectile must deal exactly three hearts of direct damage, leave a lingering fire cloud that chips half a heart, and then place the item on a five-minute per-player cooldown before it can be fired again.

I need this written as a standard Spigot/Paper plugin (1.21+) so I can drop the JAR straight into my plugins folder. Cooldown, damage, potion level and display name should all be adjustable in a config file, but the default values above must be pre-set. Please include the full, well-commented source along with the compiled JAR so I can tweak or extend it later. The mace is crafted with the dragon egg and a breeze rod
