If you are a pazifist, simply because you can’t get any gear outside or got no money for crates, the enchanting table can make better semi rare pickaxes than the semi rares can offer.
You need a lot of exp, because it’s 1.7, and a lot of luck to get an Efficiency 5 Fortune 3 pickaxe, where as Unbreaking is useless inside the mine, and anvils don’t work.
Also recommend a gold pickaxe with efficiency 5 to break all the stone real quick. (can’t break ore as fast)
