I've been thinking about this for a while now so i'm going to say it now. Is it possible to let slap gamers on MC to spawn the wither in the end considering there's nothing truly important there. However, u can not spawn it there and just leave it there, u must kill it or else you will be idk tempbanned or sometin. anyways i think being able to spawn the wither boss in the end would be a great idea, but it would involve some rules.
