How to make a super cheap and efficient mob farm with very little redstone. Great for skyblock.
I suggest you build an iron farm first, and build a smaller simpler mob farm to get the 13 redstone from witches.

  1. (even though this is a very old vid, it's still one of the best mob farms for survival.) most people don't like the big hopper collection pad, but if you make a tube from the center hole all the way down to the floor you only need 12 hoppers for the collection pad… but if you have an iron golem farm you won't have any problems…

  2. Thanks a bunch for this design. It works for me in 1.11.

    The biggest problem for me was to create a spawner. After that you can make the mobs fall into a water stream to even out different height floors damage and then drop them 22 blocks to where you kill them. This way you get exp and not only loot. It seems like such a waste to not use the exp from this mob-avalanche. =P

    And as the hole is 4 blocks wide and you need 2×2 blocks to get spiders, it only takes 8 hoppers below. So 10 hoppers, 50 iron. Not 300+ XD And with how much other materials the walls take it's funny to hear 300 iron is too much.

    But man does this thing lag!

  3. Works! Built it in survival mode on PS3 and have drop surface 32 blocks from opening above. Reduced size of drop surface slightly to cut back on # of hoppers used. Had to build a crows nest about 72 blocks above the top of the spawner to maximize the number of mobs spawning. After running stopwatch for an hour I got 1,586 items when I returned to ground level to check. Not bad I'd say. Time and resource intensive when building in survival so be prepared to chop up a lot of wood if you're doing it the old fashioned way as I did.

  4. Built this in XB1. Works fantastic. Thanks! However, some spiders survive the fall of 30 blocks. Looks like some manage to grab the wall before impact. Is this something you experienced? Ideas on how to prevent that?

  5. If anyone is considering using top half slabs in this build to save on resources, I did the same in 1.11 and no mobs would spawn. Not quite sure why this is but when I replaced the slabs with full blocks of worked a treat. Thus I would advise not to use slabs.

  6. Hoppers can be replaced with hopper carts and an unloading system. May or may not save a lot of resources depending on the situation. On the one hand, hopper carts cost 10! iron. On the other, if it replaces even two hoppers, that's worth it. On the third hand, one still needs a hopper to unload the cart, and furthermore, one needs some amount of iron and gold and redstone for the minecart system. There is also the legitimate problem of how to avoid the cart not being able to keep up with demand, as one cart can only unload on one hopper at once.

  7. This Design is considered "Cheap" which is a total lie he says and I quote "pretty low resources just 13 redstone" No where does he mention the amount of cobble one needs for this i used at least 2 double chests of cobble "Cheap" he said however this design does produce a decent amount of mobs so if you've got blocks to burn go for it.
