Vayne, The Night Hunter.


Lore:

The world is not always as civilized as people might think. There are still those who would follow the blackest paths of magic and become corrupted by the darker powers that flow through Runeterra. Shauna Vayne knows this fact well. As a young privileged girl in the heart of Demacia's elite, her father tried to convince her of the constabulary's ever-vigilant eye. Young and naive, she truly believed that her world was one of perfect safety, until one night, when a twisted witch took interest in her father. The malevolent woman overcame her father's conciliar guard, then tortured her family before murdering them. The young Shauna escaped only by hiding herself and then fleeing once the hag had departed, plagued by the screams of her loved ones as she ran. A burning hatred was born in her that day, one that could never be denied.


Vayne was about to take care of herself using her father's money, and she began to train as soon as an instructor would have her as a student. By the time she was a fully grown woman, she had become a grim warrior. However, the fields of battle were not to be her home. Demacia needed a protector, one who hunted those lost to the darkness. Shauna used her family's contracts to become the first Night Hunter, and now her prowess is the stuff of legends. It is said that those who practice the black arts quake when they hear that the Night Hunter is on the prowl. Despite her crusade, Shauna has looked at the League of Legends in horror. There are champions who have clearly lost themselves to the blackest of magics, and who have been embraced within the League even though they should be put down for the safety of all. The time has come for the Night Hunter to execute her secret mission - to purge the League of Legends.


Not all shadows are to be feared. At least, if Vayne has her way.

Pros: + She is a Ranger, meaning she is a Farmer. + With her Trumble, she can last hit very easy. + She is a Range Type Champion, meaning she is good at Farming. + She can last hit very easy with Tumble. + She can STUN and KNOCK BACK with Condemn. + Extreme damage with, and without damage items. + High initial and late game damage. + Insane amounts of damage, even to tanks! + Great movability because of the passive Night Hunter. +Best chaser IMO. + Great at taking down turrets/inhibitors. + Final Hour and Tumble activates the invisibility.

Cons: - Squishy. - No real escape spell. - Shut down with CC. - Usually targeted first. - Needs farm to be effective. - Slow initial attack speed - Slow initial movement speed - Kinda hard to master - Easily zoned - Very Bad skins :/ Dragon Hunter and Heartseeker are the best. - High expectations of Vayne players

Just like you saw top, this is my ability sequence:
Night Hunter
Vayne gains 30 Movement Speed when moving toward nearby enemy champions.Night Hunter is one of the reasons as to why Vayne is so scary. The ability to chase down enemy champions with an extra 30 movement speed is insane. Although 30 movement speed doesn't seem like much, it actually helps you pick up a lot of kills when chasing. For example, if someone flashes, assuming they don't go over a wall and you still have vision of them, this passive and your tumble helps you catch up to them with ease.
Tumble
Vayne tumbles,maneuvering to carefully place her next shot.Her next attack deals bonus damage.Tumble isn't used for much early game, except for creating a little distance between you and the enemy, adding a little bit more damage to your next attack, and for last hitting a little easier. End game, however, this ability helps you extremely well. At level 5 Tumble, your next attack will do 50% extra damage, close a little distance, AND give you stealth when your ultimate is up. This ability will scale well if you have a lot of AD and will give you a higher damage output for its short cooldown.

Silver Bolts
Vayne tips her bolts with a rare metal, toxic to evil things. The third consecutive attack or ability against the same target deals a percentage of the target's maximum Hearlth as bonus true damage. (Max:200 damage vs. Monsters)Silver Bolts, or the skill that Vayne has that all tanks fear. Dealing 8% of the enemy champion's maximum health every 3 attacks is insane, since your auto attacks should be doing a lot as well. Attacking someone with around 300 AD, depending on your build of course, with let's say, 1.5 attack speed(though it shouldn't be that low), it would deal about 900 damage + 8% of their maximum health in a total of 2 seconds! (Excluding armor)

Condemn
Vayne tips her bolts with a rare metal, toxic to evil things. The third consecutive attack or ability against the same target deals a percentage of the target's maximum Health as bonus true damage. (Max:200 damage vs. Monsters)This ability will really shine when you land it on your opponent and they collide with terrain. This ability will do extreme amounts of damage early game, because it does DOUBLE damage when they hit terrain. It might fall off mid game if the opponent stacks armor, but the stun is nice still. When you Condemn someone to a wall end game, your auto attacks should pick you up at least one kill.
Final Hour
Vayne gains increased Attack Damage,stealth during Tumble, and triple the bonus Movement Speed from Night HunterFinal Hour is incredibly useful in team fights, and if you are skilled with Tumble, that 1 second stealth can save your life, and pick up kills. Final Hour is used in three situations.
-Grants you stealth on Tumble(Might save your life)
-Using it right before team fights
-Chasing someone down and you need the 3x Passive bonus totaling to 120 bonus movement speed.

There are many times in which you can condemn. For example, if your support sits in a brush, and someone attempts to facecheck(which is to walk into a brush that is not warded to see if anyone is hiding) a brush, you can tumble and instantly condemn them.
WARNING.When you Condemn them,make sure your Condemn pushes then in to a wall.(for the stun o take effect)

My runes are:
These runes are the best for some GOOD offensive power and a litlle survivability (on any lane).

BUT, you can change the 9 x Greater Seal of Armor for 9 x Greater Seal of Attack Speed
and the 9 x Greater Glyph of Scaling Attack Damage for 9 x Greater Glyph of Magic Resist
This 2 Changes will offer you less damage, but more survivability.
It is your choice how to make your runes.

Also,if you dont like the 9 x Greater Mark of Attack Damage ,then you can change them for 9 x Greater Mark of Desolation .This will offer you Armor Penetration, but less damage.

Just like you saw in the top, these are my masteries:
But, if you desire to play more defensive with Vayne,then keep only 9 points at Offensive and put 21 points in Defensive.
This is another example of how i played in another times and still playing when needed:

As you can see in the top,those are the items i buy.
But ,like always, you can make some changes to my Build. (lol, no one is stopping you :P).

In the first place,the Doran's Blade and the Berserker's Greaves are a must because of what they offer you: 100 Health, 10AD, 3 life Steal and 25 Movement Speed.
Hmm,i even have a suggestion for you.After buying this 2 items, try to buy 1 to 3 Health Potion's.Believe me when i say,it will help you stay longer on your lane, and in some situation, it can even bring you, your salvation.

After that, if you feel like you are "pwning" them on your lane, or you know you have a great support with you, then i recommend buying a second Doran's Blade.
If you aren't "pwning" in your lane, or if you don't have a support with you, then forget about the second Doran's Blade and continue buying the items i've been showing to you in the top.

The next item for you to buy is Zeal.I chose this item because of its 20 Atack Speed and 8 Movement Speed.Of course the 10 Critical Strike Chance is important too,but for me especially isn't, but it will be later.

Afterwards, Vampiric Scepter will be the next one, because of its 10 Life Steal, which will help you in any situation, and i bet that you think so too.
After buying this item, try to make as fast as possible the Bloodthirster.
When you get to this point, now will be the hard part.Depending on what champions and items the enemy team has(and how good they played untill now), now is the time to decide what items to buy:

• If they are good, and are focusing you too much, except for you to play more safely,i encourage you to follow my build, meaning to start buying Chain Vest in order to finish Guardian Angel. (If they have too many AP champions,then buy first the Null-Magic Mantle, not the Chain Vest.After finishing the Guardian Angel,continue buying the items from my build in the order that its displayed.
  
• After purchasing the Guardian Angel, if they have too many AD champions(like 3of5,4of5, or especially 5of5, then i encourage you to buy Thornmail.After buying the Thornmail, finish the build by buying Infinity Edge.
  
• After purchasing the Guardian Angel, if they have too many AP champions(like 3of5,4of5, or especially 5of5, then buy very quickly Force of Nature.After buying the Force of Nature, finish the build by buying Infinity Edge.
  
• If they are playing poorly(like how we like to say, they are noobs),then after purchasing the Guardian Angel and Infinity Edge,replace the Frozen Mallet with another Phantom Dancer or Bloodthirster.
  
  After finishing the build, buy Elixir of Agility and Elixir of Fortitude.If you want to have less cooldown,then buy a Elixir of Brilliance.

Flash and Ignite are the summoner spells i take.
But you can also replace Ignite with Exhaust.It is your decision.

Flash: Flash is extremely useful for closing the gap on enemies if they're running away, or for jumping over walls to escape from salivating enemies vying for your blood. Flash is a must have on all squishy champions with no escape mechanism. While Vayne has Tumble and Condemn to escape and push back, Flash is a fail safe, as well as being a strong offensive tool.

Ignite: Ignite is very good in a situation like, when you are fighting 1 vs. 1 against Ezreal or Kassadin ,you active Ignite on them,when they have.. like 200-300hp maximum left,and they use Arcane Shift or Riftwalk in order to escape, even if they do so,their escape will be in vain because they will be killed by your Ignite.

Exhaust: Exhaust can be considered by some players essential on Vayne to gain the upper hand in any 1v1 fight, or clustered teamfight. Activating Exhaust on the enemy AD or AP carry immediately shuts them down, and allows you to perform at your full potential. As with Flash, Exhaust can be used offensively, or defensively.Because of this reason, i didn't want to exclude this summoner spell of it's place.

The rest of the summoner spells:

• Heal
• Revive
• Smite
• Surge
• Teleport
• Cleanse
• Clarity
• Clairvoyance

are not good for Vayne.

Heal: You can use heal if you really...but really want to play defensive.I for one,consider it very useless because early game,it may save you in some situations,and maybe grant you one or two kills, but in late game,HEAL is very useless.In late game,it wont save you anymore.

Ghost: The same goes with Ghost.It can be used to run faster with it,or to chase an enemy champion in order to kill it and have a kill.But if 2 enemy champions, or 3 or all the enemy team focuses you, GHOST is useless, it wont offer you an escape oportunity.
