My goal is to make it so slayer weapons cannot be used on any other players
slayer weapons are top tier weapons on my server and i dont want them used on players

The evolutionairy pets shouldnt be able to attack other players, is this possible?

Any lines of text I can drag n drop would be amazing thanks in advance.
