[2020] I think demolishers are to much :)

I’m currently working on a base design in creative mode which I hope to implement ‘for real’ without creative mode when perfected. Sometimes I test it by spawning 25 demolishers at once.

They’re scary at first, but with some trial and error you can form an effective defense against them. My advice is to make them (and all zombies) spend so much time traveling towards the player, they can be killed (however you like) before they get the chance to do much block damage.
