So, I tried to use lapis on a scythe, and soon realized my stupidity.
The scythe counts as a weapon, so therefor it receives looting enchantments when lapis is applied.
After that, I tried to enchant a sickle, which, to my surprise, actually worked.
I got fortune III on the sickle, and it worked on vanilla crops, but sadly not on Magical Crops.
Dangit, thought I would be able to cheat
