The preparations to fight Ed were as follows.
One, Ed would wear extremely heavyweights on his arms and legs. It was hard to believe he would be fighting anyone like that but that was the plan.
Two, the challenger would have to wear from light to heavy armor. The armors didn't originally have weight differences but Ed made use of his ethereal spark to add or remove heft. They just needed some form of protection so Ed's weighted fist didn't accidentally dent their skull. Wait… Armor didn't seem that helpful in that case.
Three, the challenger would have the option to drink one of Ed's potions. The reason why it was optional was that they were limited and also because Ed wasn't keen on forcing unknown substances into the bodies of others. The- The alcohol had been an exception.
