Disclaimer I'am really not good writing guides but I want to put a strong build out there for vayne players specially for (s3). Currently meta is hard on ADC's because the buffs on tank items and Bruisers and close gap abilities. Including every item been nerf for AD's and movement speed nerf.

Blade of the ruin King: Reason I prefer botrk over bloodthrister first is simply the item passive and active. The %4 damage on attack good against bruisers and health stack and syncs with Silver bolts.

Next the active helps kiting when needed or to close gaps between other champions that would otherwise escape. Plus it does %50 of you attack damage and heals you even.

Phantom Dancer: For attack speed-Crit-Passive- Syncs well with vayne.

Infinity Edge: Attack damage-crit-passive-sync's with vayne

Bloodthrister: Attack damage-life steal-stacks- Keep vayne long and harder in any fight- specially with Blade with the ruin king

Frozen Mallet Health-Kiting and closing the gap between other wise other gap closer.

Lat Whisper: Armor pen-attack damage- With complete with the other items. You'll be able slaughter tanks, health stack champs, Kite and kill and close to finish the deal.

You'll Be a force like no other if played right.

Vayne Need's the cleanse for vary of scenarios. Stun's-Ult's-Ignite-Exhaust.Keeps you longer harder in fights. When they blow ignites and exhausts even ult's.

Flash-Another great ability for escape or position tool. I trust most summoners know how to use it fully.

Riot is buffing the Blade of the Ruin King on Public test realms. Suspect hard transfer from follow bloodthrister builds into follow Blade of the Ruin King builds for ADC'S with that attack speed and the stats on the item. It's too good not to build on ADC'S on current meta.

This is a very powerful build for vayne and looking forward from feedback when tested. Thank you. Now go carry your team:)
