Shaw Fujikawa, a Last Whisper gives 35% armor penetration. Armor penetration of 35% against Garen means 35% of his total armor is subtracted, then Garens 20% bonus to bonus armor gets applied, then Garen's damage modifier is calculated from the formula given on the armor page of this wiki.

Because of the order of operations the 35% subtracted from Garen's total armor is subtracted from his bonus armor first, so he does not get the 20% bonus applied to that portion of his armor for that attack. Effectively, compared to the armor number you see on the screen a champ attacking with a Last Whisper does damage as if it were 42% lower. Darius' max rank hook gives him 25% pen, but it is effectively 30% against Garen. Darius with a Last Whisper gets 72% armor penetration against Garen. I think this a big weakness for Garen.
