dupe

I just want to dupe in a server so i am using wurst cilent 1.16.5 so can you say how do i dupe sorry for spelling mistake

@Alexander01998 can you please say if you are free

so when i try it with the book quill it say's if you see this it did't work

thing is that if there was a dupe possible it would have been already added

but at the same time the servers would get patched really fast and the dupe wont work anymore
