Set Up Multiple Enchantment Targets for a Trading Hall
Add Your Target Enchantments
Before cycling, decide which enchanted books you want to find. Open chat and use the command /librget add <enchantment> for each one. For example:
/librget add mending/librget add silk_touch/librget add fortune 3 20
You can specify a maximum level and emerald price limit by adding them after the enchantment name. The mod will only accept trades that match your criteria.
Position Yourself in the Trading Hall
Stand where you can see multiple librarian villagers and their lecterns in a single row or cluster. The mod cycles all nearby villagers simultaneously, so you don't need to move between them.
Start the Cycle
Press J to begin automated cycling. The mod will break and replace lecterns for all nearby librarians at once, checking their trade offers against your target list. When any villager offers one of your desired enchantments at an acceptable price, the cycling stops and you can complete the trade.
Press J again anytime to stop early if needed.
