Hey everyone! MCSWAG here to bring you Minecraft's LARGEST grinder! This is a redstone mob spawning structure I made in a flatland world that turned out to work pretty well. Please note that his grinder is very impractical to build in legit survival because of the immense amount of pistons and such I used to make it,and that in order to make it work as well as it does in my flat world you need to light up all the caves in your area around where you build it. What's up with all the torches? It's so mobs can't spawn within a 150 block radius of the grinder, giving it it's maximum efficiency. You guys can check the link if you want to check out the world and play around with it. If you like the build or want to see more from me, please diamond the post and or comment! I'd really appreciate it! Thanks guys and peace
