Since Arcane Knowledge is 10% magic pen, and Void Staff is 40%, how much would that be? I know it's multiplicative I just don't know how to figure out how much magic pen it is.

So it's 50? I was just wondering because Archaic Knowledge and Void Staff somehow added up to 49% magic penetration.

Doesn't stack like that. It stacks multiplicatively.

I think it's somewhere around... 46% but that's just my best guess.

Alright, thanks. Maybe I'll just buy a Void Staff in a bot game and see what the cheat sheet says :p

Yeah, I mistook multiplicative for additive and I realized my mistake and I changed it. Isn't that what the edit button is for? Thanks for your support :)

Yeah. Well I saw earlier in a wiki post that it was multiplicative, I don't know why I put additive.

10% reduction = 0.9x MR. 40% = 0.6x MR. 0.9 x 0.6 = 0.54x MR which is equal to a 46% reduction.
