Librarian’s Balance Data Pack (1.21.11, 1.20.1) – Custom Trading and New Mechanics

Description

Librarian’s Balance Data Pack is a datapack or mod that enhances the progression of obtaining enchantments from villagers. It introduces a system where librarians can resell duplicate enchanted books that the player already owns, creating a more balanced and progressive approach to enchantment trading.

Normally, players need two identical enchanted books to upgrade an enchantment level in an anvil. With this datapack, librarians now sell duplicates of your owned books in exchange for emeralds. By combining these books in an anvil, players can upgrade enchantments step by step, from Level 1 to Level 5, through trading and experience investment rather than relying solely on random trades.

The maximum random enchanted book level offered by new librarians is limited to Level 3, encouraging players to use the new trading mechanic for higher levels.

Features

• Customisable Trades: Place an enchanted book on a librarian’s lectern to change their first or second trade to match that book. This gives purpose to found books. Treasure enchantments produce sealed, untradable variants when traded this way.
• Limited Random Trades: Random librarian trades go only up to Level 3. To obtain Level 4 or 5, use the custom trade mechanic – purchase a duplicate, combine it in an anvil, and reinsert it into the trade cycle.
• Rare Mending: Librarians cannot trade Mending by default. Players must first find it in End Cities or Ancient Cities (similar rarity to armor trims). Once found, it can be traded via the lectern system.
