My Witch FarmI've gotten a few inquiries about my old witch farm and I'm going to make this guide on how I made this thing. Please note that I have taken some extreme measures to make my farm as efficient as possible. This may not be necessary for some, this is just my preference.Table of Contents:Step 1: Finding a Witch HutStep 2: Building of the Witch FarmStep 3: Cleansing the AreaOptional Addition of Iron FarmQuestions/Answers-= Step 1: Finding a Witch Hut =-Edited on July 29, 2016First step is to find yourself a witch hut. In my opinion the best option is to look for a hut that doesn't have much land around it. The less land around you, the less you have to dig up. This can be tricky as sometimes when there is a lot of water around, you risk the hut itself being in a different biome. We'll get into all that in a bit though.On EMC you want to use the /map feature to make sure your area is completely undiscovered. This will help prevent finding a broken biome. A broken biome used to happen in games pre-1.7. Because of the way world generation was changed in 1.8, this often would break or re-zone previously discovered biomes. This is important because for a witch hut to work, it must be in a swamp AND be a verified witch hut. Any of these conditions change and the hut it useless.First let's find a witch hut.So you found your witch hut:First thing you want to check is that witches are actually spawning inside the hut or even on top of it. Sometimes the hut will not register as a witch hut and will never spawn witches. It's rare but can happen. So once you verify that witches can spawn, you want to make sure that the entire hut is within a spawn biome. The reason for this is that you want the maximum amount of spawn blocks for your farm. A witch hut has a spawn area of 7×9×5. Any blocks within this area that are not within the swamp biome will spawn all mobs, including witches, but you only want witches. To check for this simply get on the roof of the hut and press F3.Where it says 'biome' on the left of the image you want to make sure that ALL blocks say 'swamp'. Just stand on each block of the hut to make sure they all say 'swamp'. If your fine with not all blocks being in the swamp biome, you can place glass blocks on those ones. This will prevent non-witch mobs from spawning in your farm but also means that no witches can spawn either since mobs cannot spawn on glass. Below image is an example:So if you are ok with this then you are ready to build the witch farm.
