With this datapack you will be able to create a sponge and also an ominous key of trials. I think many had a problem with finding a sponge and ominous key, this datapack solves this problem by adding balanced crafting. To craft the ominous key you will need: 2 iron ingots, 2 copper ingots, a diamond, a default trial key and 2 deep slates. To craft a sponge you will need: a bucket, 4 yellow wool and 4 feathers. Don't forget to write the command /reload in the chat after installation Enjoy playing with the datapack :)
