(The 1.14 version of this datapack works just fine with 1.16!)
This datapack is self-explanatory-- Instead of making a skeleton kill a creeper for a disc, you can now craft them yourself!
To use this datapack, just unzip the datapack file, and then move the extracted file over to the "Datapacks" file in your world save.
All crafting recipes can be found in the recipe book! To unlock them, obtain a Jukebox.
