Vayne is by far the best tank killer in the game, while still being able to take out mages etc, vaynes light is really shown in how well her tumble is used. The best way to kill fast is to proc silver bolts due to the build - bloodrazor - and att speed and your passive this shouldn't be a problem as such but there are alot of good ways to proc Vaynes silver bolts and still get stun, advantage after, kill, assist , praise from your team.

BTW this is my first build/guide please leave comments to help me make better ones.
Thanks

Pros
Very Mobile
Very high burst
Becomes op really fast
Once op theres no going back

Cons
Squishy as hell
Focused alot
If you can't tumble you're screwed
Needs good positioning

My runes are quite simple as you can see above i take Attack Dmg
Crit Dmg Attack Speed and A little speed and more Crit dmg

People ask me why i go for Attack Dmg over Armor pen, because sheen scales off Att Dmg and if you are fighting another carry they don't generally have armor I'd generally go for Attack Dmg but if the other team has Jarvan or someone very beefy and high Armor like Taric aswell take armor pen.

I LvL up Q first because Q also scales sheen, it has lower c/d the higher the lvl and in general it's the bread and butter of Vayne.
I take W then to go with Bloodrazor and to start taking down beefy tanks.
I leave E til last because i only use it for stun and escape and not so much for dmg because of the high mana cost. ( highest mana cost for Vayne )

Tumble is an amazing skill a mini flash ( can't go over walls ) that not only resets your attack timer but also give you a increased attack, now if you stack sheen you get double that bonus, giving you a very high dmg skill early game. Tumble can dodge skill shots, maybe get out of range of ulti's (Nunus / Morganas) and the more you lvl it the faster the c/d becomes.

Amazing Summoner Spells
Flash - Amazing escape or initiator it can also be used to position yourself for E
Exhaust - Lock down a kill or to again escape
Good
Ghost - Good escape or to catch up but Vaynes passive and ability's should do the trick
TP - Only if your doing a 2v1 and ONLY that, unless you want to move around the map that much faster
OK
Heal - Good if your not very good with carry's yet
Ignite - To get a kill - but you should be able to with W anyways
Cleanse - You shouldn't need this unless you have no form of tank ( not even a off-tank )




The rest are just usless on Vayne - I don't need to explain.

Basically silver bolts means that ever 3 att against the same target will deal bonus true dmg + true dmg to 4/5/6/7/8% of their mxn hp.
Condemn can trigger silver bolts and therefore Vaynes fastest way to trigger silver bolts is.
Attack Tumble Attack Condemn BUT!! Only use condemn to get them 1: into your team 2: to stun OR 3: put then into a position where there's no escape (Barons/Dragons Cave)

Condemn : Vayne shoots a arrow from her crossbow (dealing dmg +50% of your ad) and throwing them back, should they hit any sort of terrain (Turret/Wall) EXCEPT CHAMPION TERRAIN ( Anivias wall - i tried Anivias wall and Trundles Piller but alas no )

Vayne is very, very fragile and therefore you should always have a healer/tank around ( preferably Taric or Janna ) so you cannot die very easy. Vayne does not ks she cannot all of her kills are hers, if she lands a 3 combo triggering silver bolts the kills is hers. ( Regardless new update ks'rs get less gold and the ks'd get more ) If you continually get ks'd give your team a heads up that say morgana on the other team is your kill, then while you get your team to help try to trigger silver bolts when she's 40-20% hp to ensure a kill (unless she's gone a little beefy 2000-3000 hp then you wanna do it at 10%hp )

I know it's a short build but I did my best on it - my first build/guide enjoy thumbs up - please give useful feedback.

I do want to improve this build pls leave comments and vote me up ^^

Thx

Have fun owning tanks ^^
