This macro is designed to duplicate diamonds in the Minecraft game and works exclusively in single player mode or on a local network. To get started, you will need six diamond ores, which can be either remelted or unprocessed. Don't forget to mine the Obsidian to create a portal to hell.

Take diamonds, obsidian and a lighter with you to activate the portal. It is also recommended to grab some chests, red ore and a switch. With this set, you are heading to hell, where you are looking for a castle. Be sure to avoid contact with the inhabitants of Hell to avoid unnecessary problems.

After entering the castle, find a spacious room without mobs and make a path of red ore. Set the switch and place a chest at the end of the track, in which you put two diamond ores, and keep the rest in your inventory.

Now go to the switch and press it, then activate the macro by quickly pressing the desired key. It is important to set the time before pressing the macro again, and then wait about five seconds. At this point, you will exit the game — do not panic, this is part of the process.

When you return to the game, open the chest and enjoy the dupe! You can repeat these actions as much as you want, and the number of diamonds duplicated will depend on how many you put in the chest.
