Librarian Merchant

(Yes I know there is already a suggestion but this is how I would add it) you can find the librarian in the well on high block halls if you look hard enough, the librarian will be in the broken down house in the bottom right of the camp the house will slowly be rebuilt as the librarian upgrades/levels up, in order to level up you need to pay enchantment points like this: 3/8/12/24 to level up (everytime there is a / it's going to a new price for a new level), here is the rewards for each level: 0. is nothing just the usual 1. is going to give you two more slots 2. will make it so you have to pay less then 3 and makes it 2 (I order to level up you must pay 3) 3. will give you powerful enchantments and all enchantments are maxed leveled 4 makes prices 1 and gives every enchantment possible, the UI is just blacksmith but book instead of anvil with the upgrade button below that, the Librarian Merchant is just the librarian villager for texture (he is reading a book by the way), Anyways thanks for listening please upvote if you agree on this and maybe check out my other ideas!
