I decided to make a witch farm, by which I found a swamp hut. So, instead of caving and lighting them up, I decided to use a frame quarry. I soon found out that clearing a 128 by 128 would take me 20 hours. Well I don't know about you but I don't want to spend 20 hours of my precious minecraft time pressing buttons, so I need to make a different plan. I could light up the caves, but there a lot of them, and the farm won't be as efficient as other methods. I was thinking the classical, go up 100 blocks and transport the witches through mystcraft portals ( one portal goes to the nether then the portal in the nether will take them to me. If mobs can go through do portals, and chunk loads cooperates then it should work, but I was wondering if there is a better method, and will my method work?
