since magic doesnt exist thats a bit of a hard one to pin down doesnt it?
Is any exagrated effect on a weapon attack magic?

Are weapon trails magic?
Impact effects? exagrated audio?

I hate this because the very same argument has been made for Game mechanics. "no i just dont want mundane thigns to have the same rules as magic".
but then you realize magic has rules for everyhting and that is the reason theres barely any combat maneuvers in 5e.
