Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
First of all buy a Long Sword and a Health Potion
2. shoes (complete)
3. Last whisper
4. then get a Dagger
5. a Stinger (complete to Nashor´s Tooth in the end)
6. B.F. Sword
7. complete infinity Edge
8. another Dagger to complete The Black Cleaver
get an amor when ever you need it on the lane.. most times after lvl 6 when you know the damagedealers (between shoes and the Dagger (2.-4.)
If you don´t need amor you also can buy a Bloodthirster for more damage. A Stark´s Fervor could be interessting too in the end game.
Be in the back till you get lvl 2
after that you got the best control against the enemies.
Mark them with the Noxian Corrosive Charge
and get them with Acid Hunter
using the ulti is up to you.... getting a champ while runnig away or just to slow him in 1vs1.
Ulti also can be used if you want to pick one char out of the group for your team.... most times this would be your death but dieing for the team is great :D
while using the ulti use w-skill and e-skill at the same time so you will be the first who attack.
