Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Hello, this is my build for Vayne.
I will add more information when I have time.
The last 3 shown items will depend on kind of team you're facing if they have quite a tanky team it will be best to get a Madreds Bloodrazor. If they build armour Last Whisper. If you are having trouble with surviving maybe the tank isn't doing their job try a Banshee's Veil.
