About this project
What does XP Expansion add?
XP Essence: Wireless Energy & Matter Replication
Overview
XP Essence redefines resource management by bridging the gap between combat experience and industrial automation. No longer is XP just for enchantments—it is now a volatile, high-density energy source capable of powering advanced machinery and specialized weaponry. By harvesting the essence of fallen foes, players can establish a sophisticated energy grid to automate production and enhance their survival capabilities.
Core Features
Mob-to-Energy Conversion: Every entity defeated in the world becomes a potential power source. Integrated systems allow you to harvest this "Essence" and store it within high-capacity Power Cells (NBT-based Batteries).
Wireless Power Grid: Forget messy cables. The mod features a Wireless Charging Logic (5x5x5 area) that automatically detects compatible machines nearby. Your batteries act as "beacons," pushing energy to any device within their field of influence.
Rarity-Based Matter Duplication: The centerpiece of the mod is the Item Duplicator. This advanced machine utilizes the energy stored in your grid to replicate items. To maintain game balance, the duplication cost scales dynamically based on the item’s Minecraft Rarity:
Common: 50 XP (Basic resources)
Uncommon: 200 XP (Metals and tools)
Rare: 1,000 XP (Diamonds and rare potions)
Epic: 5,000 XP (Netherite and powerful artifacts)
XP-Powered Weaponry: Harness the grid to fuel your arsenal. Weapons can be imbued with XP charges to deal devastating bonus damage, release special particles, and execute custom procedures upon hitting targets.

This XP generator consumes the life of mobs and extracts their XP. Place it on the ground and any entity within 5 blocks will be drained.

A battery that stores XP generated by machines and distributes it to other nearby machines. It's used because the generation machines don't store XP when broken. To recharge it, add it to the slot of any generation machine.

Mining machine: This machine mines any type of miner in a certain area. It consumes 10 XP from the player to perform this action.

Draining Dagger: This dagger has a chance to drain a certain amount of XP from any entity.

This item duplicating machine uses XP from a nearby battery to duplicate the item in the first slot, currently consuming 50 XP points per duplication.
All items mentioned can only be acquired in Creative mode. A more complete version will be released in the future. If you have any tips or ideas, leave them in the comments.
