I need villager traders (especially experts) to give me some advice, please. I had a villager that had a good book trade, Efficiency IV, but after trading with it a few times the book trade changed to some book I don't care about. Will the villager Ever trade Efficiency IV book again? If so, how do I get my good book trade back? Thanks.
Probably not. If a villager switches trades but the type of trade is the same thing, I don't think you can ever get it back without eggifying and trying again.
What happened here is that the villager dropped the book level which in this case was IV, down to something lower. So you most likely have a level III book trade now. I'm afraid it'll never change back up, only go down until it reaches a level I book like Silk Touch, in which case it won't ever change.
Yeah it became Efficiency II book in this case. Will 1.8 help get Efficiency IV book back, or should I just egg him? Thank you for helping.
For future reference, if you get a villager with a good book trade it'll be best to save it because in 1.8 enchanted book trades on villagers will never change.
