I've just found a villager in the village by me that does 19 wheat for an emerald. Sounds like a bargain as my wheat field is a bout 200 big.
a. Anyone got better?
b. Anyone got a villager that wants emeralds for something decent?
One of libs villages I think the oppressed has for 11 or 12 emerald for some diamond leg armour
