Lexicon Logic Engine Mod automates the process of cycling librarian villager trades to find specific enchanted books. It works by repeatedly breaking and replacing the lectern workstation until the villager offers the exact enchantment, level, and price you choose. The mod functions on the client side, which means it works in singleplayer worlds, LAN games, multiplayer servers, and Realms.
