trin force is not needed at all, just build more AS

Magical Penetration is useless on Vayne, NONE of her abilities use it, also, rushing infinity edge and bloodthrister before tank items is a terrible idea on Vayne since she is focused a lot. I tried your build 3 times, and consistently had to make a lot of changes. Sorry bro, just isnt a viable build. Good idea though!

I think the Build is good...and the Attack speed is discutable...i think the Attack Damage way is better.

Amazing build...you don't need AS for vayne...love it tnx:X

There is enought attack speed for Boots Black Cleaver and Trinity force...you are just gelous on my build babe >:P

There's not enough attack speed for your passive on silver bolts to be viable, your making Vayne into an Ashe with that build, sorry, but I lost 5 games using your build before I decided to post.

This is the most extrordinary build i've ever seen in my whole life

Its a very good Build.Tnx for the instructions i will follow them.
