For a long time, I used some other builds for this character, but slowly I realised, they all got some weaknesses. So by that, Im started to think a little about the items, the things I should buy, to make my kills the Sweetest so far in the team.
Probably some people will find "bad" chooses in my build too, but I swear, I couldnt do it better with other builds. You should try it once, or more ;)

Note: Everythings got their own function, so all is fine for me at this build. I gladly answer the questions, be free to ask, and know why I did what you dont understand.

First of all, lets see the runes.
As you start to think, what is good, just for the first level? Hmm... No matter what you get for the opposit team, becouse you already have Armor penetration, which makes to kill anyone so fast, and we dont care about the armor.
The other grup of runes will be Attack speed. Just a little help for the Armor penetration.

Note: this build is a speed based build. You have to be Extremely fast! The build requires it :P

But dont worry, the runes will help you on the other levels too, not just the first ;)

I wouldnt like to talk too much about that, its simply what the build requires.
+ damage, a little critical, some life steal to help you stay in line longer, more Armor penetration, to make the runes more effective, and also a few defensive points, for the long life.

Lets start with a Regrowth Pendant, and a Health Potion. This two item will help you to stay in line even if the enemy is some ragekid, or just rushing like a madman^^. You should save the Health Potion for later use, when you have around one block health. If you play well, that should be around level 6.

The second wave of item purcase is Boots of Speed and Vampiric Scepter. The speed now helps you to catch some candy and the life steal is really cool. Many times the enemy thinks when you got low health they will own you, but fail - your healt runs up with the regen pendant, the life steal ability from Hiten Style and the scepter.

Lets move on, we now buy the Ionian Boots of Lucidity, and if you got enought money, Zeal. Dont worry about this boots, it far better than you think. Many times I needed only 1 max 2 second to catch someone Before. Now thats fixed! Noone runs away mates ;) Zeal also let you to hit as you just like to.

As leveling, you can see that some people are really nasty for the other teammates, and cheeky as trying to run around the turret. Lets buy this Recurve Bow, so we can get them even near the turret.

As fast as we can grab the Sword of the Divine, and thanks to our attack speed, the passive ability will occure more than it suposed to. We get extra Magic damage, very often. Not many people care about both Armor and Magic resist too, so we always got some gift for them. For the same, we get Phantom Dancer, and we continue dancing around the enemy turrets, getting some extra kills. Its speed boost helps you stay at their back, and we can really ignore the turrets damage.

We just reached the warzone, but we already got enought money for the next two item: Executioner's Calling and Cloak of Agility. We continue our sweetest kills - the blade supported with attack speed is amazing. Your health is nearly always on top, as the critical damage gives extra regen.

Now just for safety, lets get Infinity Edge Guardian Angel. I guess I dont have to explain anything now... Infinity with this setup owns, and you can even have fun running around the enemy base, getting your rats down, coz you cant fall : Its Guardian Angel babe ;D

The skills are easy. We get the Hiten Style to stay in line at the first levels. We can even get 2 enemy with it, if our mate is useful.
I always try to max out Equilibrium Strike first, becouse its a great help to strike down someone.

Both spells are wonderful. We can catch nearly anyone with Ghost + , and even we can run away with Flash from an other enemy or a turret or both^^. It can be combined many ways - Be creative!

I dont recommend jungling. You are effective enought at the lines, even at 2,3v1, and you are able to help all the other lines. Hold your eyes wide open ;)
