Hey I just had a quick question, are iron golem farms allowed and possible in skyblock on this server?
Get a zombie villager and give it a golden apple and weakness pot to get villagers. Then, you have to build an iron golem farm so that you have the villagers surrounding a centre(where the iron golems will spawn). I'm pretty positive it's possible.
Yes it's possible, but I've seen other players try to build it but failed. You can find a Zombie Villager and do what @GizzBots told you.
