[Stick of Truth] How does the combat work in-canon?

(warning, there might be some slight spoilers to get my point across, don't read if you're not done with South Park: The Stick of Truth)

I know i might be looking too deep into this, but how exactly does Cartman's LARP battle system work on the various enemies that are unaffiliated with the game? Especially some of the attacks like Butters' lightning and Professor Chaos.

The new kid's abilities make enough sense since he's using realistic items to horribly maim the enemies, but how does Butters zap people, and how does Stan's fake sword do such serious damage to people? And why are people like the aliens and secret service playing by LARP rules of turn-based combat?

Is there a reason, or is it just rule of fun because South Park?

It's because the Stick of Truth *really does* control the universe. When Cartman & the gang instituted the rules-based form of combat, the Stick of Truth caused everyone, in-game or otherwise, to become beholden to the LARP rules that the kids playing by. Similarly, it caused e.g. Butters' "Smite them with Lightening" attack to *actually* smite someone with lightening, because the rules of the game said that's what was actually going on and The Stick says that the rules are real.
