This mob farm is gnembon design and i built it in my survival world and i want other people to be able to use it in their own worlds.
To paste this build you should stand in the middle of an ocean for maximum mob drops, when you paste it stand flat with the ocean on Y=63 and when it pastes it should paste above you, when it does you'll have to remove the dirt around the farm do the top layer first and then the bottom layer after. Then to use it afk at the glass platform in the sky for maximum efficiency. You'll also need to make a hopper system at the bottom in the centre in a 5x5 square to collect loot.
Enjoy the Farm.
please tell me if there is anything wrong with the build or any bugs with the build.
