Very decently explained a bit more vague than other you tubers but much more explained in a short period of time also to increase iron production trap all the cats in a area near the farm just dig a 2x2x2 hole where the dropshould be afk for an hour or so kill all the golems and push the cats into little sections near the farm and dig the kill hole and ta da

Last question how far can golems spawn outside of the farm and is there any way to make its shadow unnoticeable and can the dropshoot be smaller

Can this be built in a mountain

Does it need to be 2 layers

Cool, what's the output like?
