Who did the math for the multiplicative values of her passive combined with Rabadon's and Archmage? Multiplicative stacking means you multiply one percentage by the other. So 30% Rabadon's times 30% passive is 39% times 5% Archmage brings you just under 41%. I think the numbers are completely wrong in this article, and I don't think Riot would be so naive not to think that 77.45% bonus AP is completely broken.
