i dont get it either

- if i have 10% magic penetraion from masteries, then i will have my damg increased

( 0.9 x magic damg ) right?

- and if i buy void staff for another 40% ( with out 10% from Arcane Knowledge ), then i have my damg increased ( 3.6 x magic damg )

- so if i have both Arcane Knowledge & void staff, my damg increase ( 0.9 x 3.6 = 3.24 x magic damg ),

it lower than if i have only void staff

plz lets me know asap if im wrong or something
