Reroll a Librarian Until It Sells the Book You Want at Your Price

Hunting for a specific librarian trade by hand means breaking and replacing a lectern over and over. Enchant Oracle can do the rerolling for you and stop when the trade matches your filters.

Prepare the Villager

1. Find or create a librarian by placing a lectern next to an unemployed villager.

2. Don't trade with it yet. As in vanilla, a villager's trades lock once you trade with it, and after that the workstation can no longer reroll them.

3. Stand where you can reach both the villager and its lectern. Keep the area enclosed so the villager can't wander off to another workstation.

Set Filters and Reroll

1. Press G and open the villager trade reroll menu.

2. Add the enchanted books you want to the enchantment filters.

3. Set a price range so the mod only accepts offers at or below your target cost.

4. Start the reroll. The mod cycles the workstation until the librarian offers a requested book within your price range.

5. Once the trade appears, trade with the librarian right away to lock it in.

Tips

• Combine several bought books afterward using the anvil combiner to keep merge costs low.
