Tutorials/Magma cube farming

Magma cube farms can be ridiculously hard to build in Minecraft. But don't give up just because you can't put water in the Nether! Here are some tips on helping you build a farm.

The Spawn Area
This might be the toughest bit. find an area to spawn the magma cubes. Try checking near a fortress.

Drop Holes and the Reducer
Since the magma cubes blindly jump in one direction, dig some wide holes for largest type of magma cube to fall in and add pressure plates to the bottom, then link it up to some sticky pistons to crush the cube's head to cut it into medium cubes which ill crush also. Make this one block above the plates or 2 if you need magma cream. Add some holes at the side of the plates for the tiniest cubes to fall out. If you need magma cream enlarge the holes to 2 blocks high for bigger cubes. They will fall into a...

Portal Room
Since they only jump into one direction (and no, I don't know what music they like), they can be portaled throught into the Overworld by filling the room with portals. Link these to the overworld, where you can place water. Since these mobs don't take damage from falling you don't need to care about the distance of the drop.

The Main Farm
Once he cubes fall into the portals they can fall into a canal system. If you let the medium cubes through, add a water grinder composed of a floor of signs with water at the top. The area where the signs are on should be hoppers that link up to a chest room.

Then carry the baby cubes over to the collection room. Now start an xp farm area.

If you wan this farm ONLY to do magma cubes, add a water elevator for zombie pigmen and wither skeletons to transport them to a despawn tank or a lava blade.
