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.
The Madreds Blood Razor is an update from Madreds Razors that you should buy right after Choth Armor and % Health Pots. After that the boots, the Fronzen Mallet then upgrade the Madreds Razors to Madreds Blood Razors. After that you can buy Randuin to slow your enemies and betters defense stats, or a Bloodthirster to greater damage autput. After that I recomend a Warmog because at this time you will be giving a lot of damage and you will onli need some more heath to stay always alive.
