How to get mobs to ignore a certain player

[Xdcool]

Hey there, I need help, I want to make a series where a player is the final boss, and i want the wither skeletons to be like his soldiers and not attack him. I still want them to attack other players, and I don't want the final boss to be in creative because we can't kill him. I can't use mods either since I will be using a minehut server. Is there any way to make all mobs, or one type of mob, not attack a certain player but still attack the rest? That would really help!

Try learning skript. With skript you can do this. Heres a series that can get you started with it.

As stated above, the Minehut youtube channel would be a good place to start off at

Please post in the correct section next time. As stated above, command blocks or skript would be the way to do this.
