How does one make a weapon buff allies other players

[Rotis]

I've been working for a couple of days on a mod that adds some ranged guns into the game and I want to make a gun that would boost nearby players stats like fire rate or critical. To be hones I have no clue how to do that. Help would be much appreciated.
