Quick Answer

Do not start with a tiny max-efficiency trading hall. First make sure villagers link to the right workstation, can restock, and stay protected. Then lock librarians, farmers, fletchers, and smiths in a controlled order.

  2. Give each slot one workstation and confirm the linked villager.
  3. Lock key enchanted books before filling every profession.
  4. Add farmers and fletchers for emerald income.

Common Problems

  • Another villager steals the workstation link.
  • You trade once, then try to reroll a locked profession.
  • The hall is not lit or protected, so villagers get attacked.
  • Java and Bedrock restocking or discount rules are mixed together.
