About this Mod

This mod is not fully compatible with JEI or any other recipe mods so I have put custom recipes in the images section.

There are multiple tiers of item duplicators: Stone, Iron, Gold, Diamond, Netherite, and then Awakened Netherite. They can all be crafted using the "Duplicator Maker". As the tiers go up, the cooldown goes down and the cap to where it can duplicate to will go up. (Stone: 4 item cap, 30 sec. cooldown | Iron: 8 item cap, 15 sec. cooldown | etc.) You will duplicate the item you are holding in your offhand by 2 each time you right click/ use keybind.

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Item Duplicator consumes the most tick time.
