Hero of the village potions found in woodland mansion

You could find potions that would give you the hero of the village effect in woodland mansions. they would not be able to be brewed like regular potions, making them harder to obtain. This would be a good alternative to zombifying and curing villagers, as you would be able to find a splash potion of the same type in a woodland mansion that could be thrown at a villager to give them a permanent price reduction. This would also give a better reason to go to a woodland mansion than just the totems of undying, as these are relatively easy to get in a simple raid farm.
