Rather than having to make large quarries for deepslate, installation of this mod allows for normal cobblestone generators to make cobbled deepslate instead, as long as they are built below y=0.

In regards to its name, it can also allow players to instamine deepslate with an Eff 5 Netherite pickaxe and Haste 2 effect. Same with axes on axe-breakable blocks. These can be disabled if you wish, which I believe you should.

We're on Paper and that looks like a Fabric mod so this isn't something we can use - There may be a plugin that does this, but even so, it goes against the identity of our server, honestly. Not sure we'd be interested in this one
