My builds are created after a long playing a particular character. I mastered it and play a ranked game. If i will win, learning, play another champion. This situation requires a perfect build, in my opinion, this is like that.

Runes armor penetration and attack speed are helpful in obtaining the first attack to kill the increasing damage and attack speed. Also useful in the later stage of the game as opponents buy armor.

All Items in this build godlike form. Twitch has a high attack damage, high chance of critical strike, a lot of HP, a lot of hp regen and mana regen, high speed, both when attacking and running. His words do not allow the enemy to approach him, even if you do not have mana to use the first skill. Build is a little expensive(17 005g), but thanks to him we are feed all the time and we have enough money to finish it with no so long game and you don't need a full build to be unstoppable.

I can not play at mid so I describe the game on the line with a partner. At the beginning of the game we have no to play very offensively that they do not become a victim of the enemy. We range so we can safely harassing opponents and be safe with no offensive action where we can get a kill. You have to be no first target of enemy. If they will focus you u have to run but when they will take another target countinue with attacking. Stealth give you attack speed so you dont need buy items for it at start. This champion is create for ganging alltime but you have to care about wards and oracle. Good luck and have fun.
