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 you need to get the Ninja Tabi
Then the Warmongs Armor, so your health get higher over the game
Your third item should be Atma's Impaler... i make you armor higher and you attack
Fourth item is Froxen Mallet for more health and to slow down the enemy.
You may not get to the last 2 items Depeding on what DPS you are going against you want Force of Nathure or Thorn Mail.
Then lastly GA... so you are really hard to kill.
At the end of the game the damage for your auto should be pretty high....about 200
Most matches I have with this build I get around a score of 15-4-14.
The amount of health you have at the end makes your passive shield pretty good.
