Minecraft Villager Farm Design. A design by Avomance in particular works wonders. Are you tired of Minecraft villagers, animals and mobs trampling your crops?
Farming villagers can be beneficial for a lot of reasons. In order to find a village, you must search for biomes. I have wheat farm designs on my list of to-dos, maybe I'll work on it tomorrow morning, but I'm curious as to exactly what you mean by effective.
You can also make a farm, where you can have dozens of villagers as librarians for.
If you're creating your own village for the first time, you might want to set up some professions.
It is difficult to do this through kidnapping villagers alone, so having an artificial breeder can be very helpful. A farmer villager is a bonus, but not necessary. So you now see why I needed a simple villager-block list.
