Let's say I have a gun that's 3000/3000 and it has a +10% gun attack or something, do I need to bring that item to a fight for the boost to be effective? In other words, if I have 500 mafia, and 500 guns that are 4000/4000, does my gun boost from my 3000/3000 gun that I'm no longer using? Or is the boost just permanent to your character regardless of usage?
I realize in present day my example seems unlikely, but with so much stat inflation around, this could become an issue with legacy contest winners pretty soon, and us normal folk maybe in a year or so.
