Deep Miner

Deep Miner is an enchantment that makes you mine the Deepslate family of blocks faster, closer to the speed of the stone family of blocks.

This means that you can instantly mine normal deepslate with Haste 2, Efficiency 5 and Deep Miner. You cannot instantly mine cobbled deepslate however, just like how you cannot instantly mine cobblestone.

You can find this enchantment in Ancient City chests. The enchantment is 3x as rare as Swift Sneak. The reason I did that is because it only has one level unlike Swift Sneak.

You can only put this on a Netherite Pickaxe and the enchantment is unable to be removed after you put it on. Think of it as permanently reforging your pickaxe or something like that.
