Well this is my first build and pls tell me what you think about my build.

Runes should be armor peneration crit change/dmg bonus and attack speed bonus because AS helps you get hp back.

Clarity is good because Twitch uses much mana at begining but at late game it's worthless so you can change it to Teleport.I think Teleport is good thing to get youself back to lanes fast and you can go help you team mates fast.

Ignite helps you get kill if target runs to turret with low hp.

If you don't take Clarity spell take Insight point off and put it to Good Hands.
Masteries should give cit change and attack rate for faster attacking and more critting.

Bloodthirsters gives much of lifesteal and dmg at max stack.
Infinity Edge gives more crit dmg.
Black Cleaver gives attasck speed and dmg and passive lowers targets armor.
Phantom Dancer gives more attack speed,crit change and movement speed.
Boots of Mobility gives more movement speed.


Items gives you AS/AD and Life Steal more you hit more hp yopu get.
