Materials needed to make a zombie xp farm in Minecraft
- 15 signs
- Water buckets
- Pickaxe + shovel
Put torches all around the zombie spawner and make a 9×9 room, leaving the spawner directly in the middle. There should be a space of 4 on either side of the spawner. Then dig down by 2.
On the back wall put down buckets of water. Where the water stops, dig down by 1. Where you have dug down by 1, put water on both of the edges so that the water comes to 1 point in the middle.
Where the water comes to 1 point in the middle, dig 2 blocks into the wall. On the first block that you dug, put down 1 sign on the top block. On the second block that you dug, put
down 1 sign on the bottom block. On top of the block, put down a bucket of water. On top of the water put down a sign and then put another sign above the water. Keep repeating this until your 15 signs are gone.
When the signs are gone, build a short platform that is only 1 block wide and put a 2-high wall around it to stop light from getting in. Then dig down 22 blocks. Make a room whatever size you want. This is where you will be when you are killing the zombies. When you kill zombies you may get potatoes, carrots, iron ingots and armour.
Once you have got this far., take away all the torches you have place down. This will maximize the spawning rates of your zombie xp farm and will allow you to get xp faster.
