What fun things have people experienced regarding "Mundane Effects" in game?
While not the big showy stuff done in magic battles, what little effects your character does is another way to show a little bit about their personality in game. From glowing notes in mid air when working out a spell, to "Flickum Bicus", to accidentally changing the color of the paint on the walls in a moment of ecstasy, these can be fun to roleplay.
