RUN THIS BEFORE UPDATE>>>> /execute as @e[type=villager,tag=trader] run function libal:villager/librarian_remove

Updated to 1.20.5! This update took a ton of effort since Mojang replaced the NBT system with components. Run the command before updating or else your librarians will lose their default enchantments! For modded, please note that custom enchantments will not work with villagers for the time being. Vanilla shouldn't notice much change. Read for more details:

Additions

• More enchantments get valued expensively
  • Channeling, Aqua Affinity, and Silk Touch at 48 Emeralds
  • Flame, Infinity, and Multishot at 38 Emeralds

Changes

• Configuration menu has been simplified
  • It was so complex that it kicked you out the game for interacting with it
• Emerald pricing has been tweaked
  • Lvl 4 Enchants will cost 38 emeralds, guranteed.
  • Lvl 5 Enchants will cost 48 emeralds, down from 64/58.
• Removed 'Mending' from Sealed books list.
  • After testing, I think it should be up to the player to decide if they want to share it or not.
  • Soul speed and swift sneak will remain sealed; one is gained from piglins and the latter is a reward.
• Books with more than one enchantment
  • Before it would select the enchant at the top of the list.
  • Now, it will choose it by order of importance. This is because of the component changes.

Removed

• Support for non-vanilla enchantments
  • Due to the component changes and the way I add enchantments to the villager trade, I can't filter non-vanilla enchantments. I already have an idea for how I will fix this though, so follow to get notified for version 3.0 which will be the next update to this pack.
• Infected librarians keep their custom book trade. (fix)
• Max_level_enchant option because of component changes & simplicity
