Abyssal Scepter isn't magic penetration. It's magic reduction. You can reduce their magic resistance to negative with certain character's abilities, such as Ryze's spell flux and Amumu's Cursed Touch. Magic penetration and magic reduction has nothing to do with each other. Buy Abyssal Scepter and check your character stats for how much magic penetration you have. It'll say 0.
