Hi guys,

I play Vayne as long as i remember, but recently i was putting more thought into it about what to build and find something original that works. After sometesting and thinking i came to the conclusions:
-Shieldbow is useless (500 shield at lvl 18)
-Wits end is ok, but it gives us very little survivability vs AP champions
-My believe is that adc's build should be balanced, going all into offense is useless. We won't deal all that dmg from 5 offensive items if we're dead ;P
I was building what most players build, and even tho I was carrying games, I was unable to overcome a scenario where I make one mistake and lose the game, or get one shotted with same consequence.

As i mentioned a bit in item section, Our core items are Kraken and trinity.
This build is all about AD, HP, Sterak life line shield 1300-1800, survi.
All items except for Odin gives us AD which scales with kraken slayer.
I'll put it into a different perspective.
AS - 3 items + runes
AD - 5 items
HP - 3-4 items
Life line shield - ~1500
Combain it with some shielding support, or CC support to peel for us and we can win any scenario.

I'd be the most greatful if you'd share your opinion in the comments about this build after you try it out.

I made 3 dummies on practice tool:
1 - 2400hp 100armor, mr
2 - 3200hp 150armor, mr
3 - 4500hp 250armor, mr

First test is dmg in 6 AA's with kraken slayer and trinity (2 items)
1 - 1500 < | 1850
2 - 1400 <--Total dmg without skills | 1816 This is with 2 Q's each
3 - 1485 < | 1700

Static shiv + trinity (still 2 items)
1 - 1282 | 1618 with 2 q's
2 - 1282 | 1647
3 - 1360 | 1620

Okay, now I'll calculate how much time do i need to get dummy to 0 hp. I will count Number of attacks divided by AS. Tests done with stacked runes from the beggining.

First build is Kraken, Trinity, Sterak, Titanic, Botrk
full build has 347 AD, 1.9AS, 3777hp, 1180 lifeline shield, 112armor, 62 mr
1 - #1 DPS 1736, TOTAL 2460, 2Q's, 4 autos,1crit #2 DPS 1832, 2459 TOTAL, 2Q's 4 Autos,1 crit
2 - #1 DPS 1273, TOTAL 3202, 2Q's, 6 autos,1crit #2 DPS 1229, 3206 TOTAL, 2Q's 6 Autos,1 crit
3 - #1DPS 1170, TOTAL 4508, 2Q's, 9 autos,3crit #2 DPS 1249, 4590 TOTAL, 3Q's 9 Autos,2 crit
ATTACK SPEED with LT stacked 2.22
Time to kill 1 - 1.35s, 2 - 2.25s, 3 - 3.6s

In each of these test I made sure that i have 0 kraken stacks on start and I was trying to get the same amout of crits for tests.

Now moving to your avrg AS build

Shiv, Trinity, Botrk, Phantom dancer, wit's end
Full build has 307 AD, 2.4AS, 2827HP, no cringbow here, 112 armor, 103 mr. AS on LT stacked 2.91 and i will calculate based on that number.
1 - DPS 1353, TOTAL 2499, 2Q's, 5 autos, 1 crit
2 - DPS 1178, TOTAL 3241, 2Q's, 7 autos, 3 crits | #2 DPS 1341, TOTAL 3149, 2Q's, 7 autos, 2 crits (51hp left)
3 - DPS 1177, TOTAL 5047, 32's, 12 autos, 6 crits | #2 DPS 1044, TOTAL 4996, 3Q's, 12 autos, 4 crits
Time to kill 1 - 1.37s, 2 - 2.06, 3 - 3.78s

Math used in time to kill (number of AA - 1) * (fully stacked AS) = Time to kill with MAX attackspeed

I don't know how about you guys but I'm not confident enough to say that i can kite on 3as/second perfectly, that's why I went a different path.
Reduce a bit AS so i can kite more comfortably and each attack sends a good punch, get more AD for Kraken slayer and make it my main dmg since as a vayne, you're targeting a champion you want to die asap, either you jump or their back lane and try to grab someone, or focus their frontlane, be tanky af so i dont get one shoted or 1v1'ed by kassa/rengar etc.

I'd say that both builds deal around the same dps but i hope that now i gave you a good reason to try it
