The Mace is a powerful weapon on its own—but what if it were a server-wide unique artifact?
OPMace restricts the crafting of the Mace to a single player per server, instantly turning it into an overpowered, legendary item.
Details
When the Mace is forged for the first time, a server-wide announcement broadcast is triggered, and further crafting is permanently locked. This legendary weapon comes pre-enchanted with illegal/overpowered enchantment levels and is completely unbreakable.
Default Enchantments:
- Density VI (Increased fall attack damage)
- Breach IV (Penetrates 60% of target armor)
- Wind Burst II (Launches the attacker upwards on hit for chaining combos)
- Unbreakable (Infinite durability)
