Weapon Binder

What does the weapon binder does? And how do I make it work?
Everytime I try it the game just says "abnormal gameplay" and shuts down ... Is there a special way to use this? Or is just one more visual hack that does really works?

u can use the 8th slot for px items only everything else crashes idk why..

It lets you use weapons that you don't actually have. Req.Close @Alen
