hello sir but you should add delay and make it so people cant dig the Bedrock at the bottem or at the of the nether so please! make more things so you can toggle it and turn it off or on
A few suggestions:
Make the pickaxe take damage (And support unbreaking)
Make the item drop instead of going to inventory (Maybe a toggle in a config?)
Make it take a configurable amount of time to break (config file)
