-The_Milkmam

I pressed the button like 25 times and wondered why it didn't work

It's not automatic but you select the ingredients and it goes through hopper into the stand and you collect it in a chest

What would I be if I can make a redstone machine that can brew potions and shoot the potions for combat and then make it look like a castle?

And the name was an accident it was ment to be the Milkman but slip of the finger.
