You clearly don't know the difference. Abyssal doesn't give a magic penetration buff at all, so asking if it gives 40 magic pen vs  20 is redundant. It gives you neither. To confirm what was said above multiple instance of the debuff aura are redundant. Enemies will only ever suffer a -20 to magic resistance, which is NOT the same as you gaining 20 let alone 40 magic penetration.
