BLESSED BE MCVXXI FOR PROVIDING YOU, THE SEXY READER, FOR INFORMATION ON HOW TO DUPE ON 2b2t. MERRY CHRIZMIZZLE, HOMESLICES.

What you will need:
-   A Minecraft 1.12.2 Installation with Forge: http://files.minecraftforge.net/
-   Forgehax: https://jenkins.daporkchop.net/job/Minecraft/job/ForgeHax/
-   randombook.txt Text file: https://www.mediafire.com/file/2c77bm2u8l1onnm/randombook.txt/file
-   At least 95 books and quills to start. (Get 5 extra if you want to dupe multiple times.)

Setup Instructions:
1.  Put forgehax.jar in your mods folder (%appdata%/.minecraft/mods).
2.  Launch Minecraft and quit. This will create the forgehax folder in your Minecraft directory.
3.  Put randombook.txt into the forgehax folder (%appdata%/.minecraft/forgehax).
4.  (FOR HACKED CLIENT USERS) Most hacked clients have an internal command system that uses a period (.) to activate. This will need to be changed to a comma (,) to differentiate between the two mods. Do this by opening “ChatCommandService.activation_char.json” in this directory: (%appdata%\.minecraft\forgehax\config\settings) and replace the “.” With a “,”.
5.  Open Minecraft and go into any server or world to set up the bookbot in game.
6.  Type in these commands (Use a “,” instead of a “.” If you did step 4.)
a.  .bookbot file randombook.txt (Sets the file to randombook.txt)
b.  .bookbot sleep 1100 (Sets the cooldown in ms. This value is large enough to not get kicked on most servers)
c.  .bookbot name 1 (Sets the name of the book. Start with the number 1 for organization. Though, you can name it whatever you want.)
7.  Find a chunk to use as your “duping area”. Use F3+G to see chunk borders.
8.  Place two double chests within your duping area.
9.  Take your books and quills and fill your hotbar with them.
10. Type “.bookbot start”. This will start automatically writing all the books in your hotbar. To stop the bookbot from writing books, use “.bookbot delete”. (For some reason they used the word “delete” instead of “stop”. Keep in mind this will not delete anything. It’s just how they decided to call it.)
11. Once you are done writing the books in your hotbar, place those into one of the double chests you just placed.
12. Now type “.bookbot name 2”. This will set the name of the book to 2. The goal here is for these written books to not stack. This is what the exploit relies on. Basically, you need to change the name of the book every 9 books. After you write books with this name, change it to 3, then 4, 5, and so on every 9 books.
13. You will initially need to write a total of 90 books that will stay in the chests throughout duping. These books should have 10 different names total.

Duping Time! (Repeat these steps unit the admin patches this exploit!):
1.  Put whatever you want to dupe into the chunk.
2.  The chunk needs to be saved. Do this by either re-logging or unloading and reloading the chunk.
3.  Change the name of the book to any unused name one last time and write 5 more of them.
4.  Place those 5 books into one of the two double chests you have the books in. This puts the chunk into a state where it will not save upon it being unloaded. At this point, you can take the items you want to dupe outside the chunk.
5.  Re-log or unload and reload the chunk. This will reset the chunk to the state before you put the last 5 books inside the chest. Your items should now be duplicated!

Things to note:
-   This does not work in single-player.
-   Duplicate some books and quills as you will need 5 every time you dupe.
-   You can’t duplicate pre-written “duping books”.
-   Whenever you want to edit your duping chunk between “dupes”, make you “save” it by either re-logging or unloading and reloading the chunk. If this is not done, there will be a chance when you perform the dupe again that the chunk will revert to the earliest state (when you initially added the 90 books and items you wanted to dupe).
-   It can take a lot of time to get enough books and quills for this exploit. If you are intimidated by the process, practice this on a private creative server until you master it.
