Yeah Lich bane is much better :) +1!

Better*

Thanks for the comment, and i think you are right about the magic pen, so i have taken a lichbane insted. The reason for the lichbane is because, you stun your enemies, and then you auto attack until your cd's are up again. So i think lichbane is a batter choice, thanks again:)

I would recommend getting a different item other than void staff at the end. The 40% magic pen gets applied after the flat magic pen is taken into account, therefore void staff isn't actually very effective at that point. Other than that it looks like a decent guide.
