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.
a good build that can be used for gain first blood and always a good score (average 20-3)
start with the first item that lol vendor suggest to buy and two heling potion, u'll need it to administrate your resistance til level 6.
As soon as possible buy the First definitive item. Berseker's greaves.
Now pump your damage and be ready to take some head:
Brutalizer is a good start but i prefer B.F.Sword (that u'll need for Infinity Edge)
After the infinity take The LastWhisper that grant you armor pen.
and after this Sword of Destiny is a good deal.
Now take phage n next take Frozen Mallet.
At the end became unreal with bloodthrister n u'll be 20-3, 20-2 .
Hope that this build will be clear.
