i made it in creative, but i do intend to build it on my survival world
i used a mob spawner to funnel mobs into an iron trapdoor that opens every 10 seconds. it would drop the mob into a 3x3 stone platorm made from a stone generator. everytime a mob fell it would push the stone a block forward. then it would sort the fresh new skulk into 3 different 12x12x12 blocks. then i would mine it with mending for xp.
thats the v1
the v2 has a system that funnels the mobs between 2 different pipes and drops them. this lets me have double the storage, but i also added a system that pull half of the skulk blocks away from the main and puts it into more 12x12x12 cubes. thats 12 12x12x12 cubes of skulk.
also for the actual skulk components, i dont really farm those. my farm is mainly made for xp and such
