The Meaning of Life, the Universe, and Everything.
i have a fairly interesting issue with my iron farm, I’ve gone with a ‘village around the grinder’ design as I feel this makes it easier to look after the villagers and they have a farm so they can feed themselves etc...works fantastic except for it fills up with witches while I afk beneath it, over the course of 8 hours I will probably end up with 5-6 witches which are then a nuisance to get rid of.
no other mobs spawn in the village area
its not on or near a swamp biome (haven’t even found one on my map yet) and is so far as I can tell a standard plains biome
what are the mechanics of witch spawning? How can I stop them? Can I capitalise on this and somehow extract them into a witch farm to process them for drops?
Lightning can turn villagers into witches. I've seen this happen in my iron farms as well. According to the wiki, the lightning will convert them of it hits within 3-4 blocks. Theoretically, you can stop witches from appearing if you have a roof that covers your villagers and extends 4 blocks beyond the pens. I have not tested this.
