This build is made for a classmate, it is for early game dominance which can make or break ur game.

For the runes u can decide to have either armor pen or ad runes as marks, it both work fine and is really dominating the early game.

This are the offensive masteries, if u want to go more defensive, remove some from the offense tree.

Item build in text with some additional information

The item build should be:

Boots + 3 hp pots if u play with a non healing champion, if u are playing with a healing champion take doran's blade.

Try to get back when u have 2k money, it takes time and u need to know how to lasthit, when you go back try to get most parts for wriggles lantern, by this time u can still use lvl 1 boots.

Finish the wriggle a.s.a.p. and get a sheen right after it.
(Why wriggle? Dragon is near botlane, for the best dragon control a wriggle is a must and furthermore its a really nice item due the armor it gives and lifesteal.)

Once u have sheen + wriggle u can get berserker greaves, or mercury threads if the enemy has high sustain.

After sheen it's time to finish trinity force in this order (u got sheen -> ruby crystal+longsowrd > phage or just buy it in 1 if you got the money, then the zeal +300g = trinity.)

Now you got a very nice item, it depends on you how long it will take before you got it.

After you got this item get black cleaver and the dmg output will be huge now.

What we got now: Bers greaves / Merc. threads + wriggle + triforce.

Where do we aim at: #1. Blood thirster, #2. Banshee / QSS (if the enemy got high sustain) #3. Last Whisper.

In the end u can decide if u want to sell the wriggle yes or no.

Try to play aggresive early, because early your Q will hit the enemy hard and u will keep hitting faster.

But this is also depending on your support, supports like janna, taric and sona can help you the best with playing aggresive.

You must know how to position urself in teambattles, this is just some common sense and shouldn't be explained by me.

Just have fun in the game and don't let yourself getting flamed by noobs, just ignore them and play the game at how u know to play it.

And remember: last hit & poke the enemy to death!
