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.
I) In first place, we'll buy a long sword and a health potion. Our aim is to upgrade this sword into sword of the occult as soon as posible in order to stack up the maximum marks we can in early game.
II) The second item we buy are a nice pare of speed boots which we will upgrade into: Mercury's Treads or Ionian Boots depending on the opposite team's setup.
III) Thirdly, buy another pair of long swords, however If u've got enough gold to buy directly the brutalizer, do so.
IV) Warmog's armor. It provides Renekton 1370 HP which further on in late game combined with Atma's Impaler and a life elixir will rise our AD!
V) In sixth place we will buy Atma's Impaler. A very nice item which will give us a high amount of damage due to our high amount of HP. In late game you can easily reach to 4.3k HP with a life elixir. This means that this item is giving us: 45 armor, 18% crit chance and 86 AD.
VI) Finally upgrade the Brutalizer to Youmuu's Ghostblade and don't forget to use it in case you've ran out of habilities!
