Desided to get the Xisumavoids headdrops for my server, while playing around with the loot tables thought it could be a cool idea to get swiftness potions drops from spider since neither of the players usually remember bringing them around, but I cannot figure out how to do it,
To download the other ones you need to make a folder in the versions folder for minecraft and put the client and JSON file for the versions in there. They all need to be named the same aside from file extensions. Once you do that, you will be able to choose that version when making a new profile with the minecraft launcher.
Is there a way to just add to an existing loot table without replacing the already exsisting one? For example I just want to add something else that a zombie can drop without taking away the already existing loot table(so it would drop rotten flesh and a custom item).
