I swear I found a fabric mod where you could give a villager a Diamond pickaxe and he would then gain that as a recipe for emeralds. More importantly, you could do this with librarians and books (So I could get one with Mending, Unbreaking, and Efficiency rather than having a dozen villagers.
Anyone seen such a mod? Or if I'm insane and it doesn't exist, anyone want o make it?
I'll consider trying to make this, I like this idea. It would take extensive setup for each item and at least at first wouldn't work for modded items unless you have a config to add stuff which would be difficult.
