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.
Start off with some good harass (solo lane). I find that if I control myself well, I never have to go back to heal, only to shop. I pick up tides of blood more than the pool because of the much better damage + cooldown. It is ridiculously helpful when harassing and quickly nuking an enemy hero down for a kill, as well as allowing you to get every minion kill every wave by level 8 or so. You should be able to get FB once you get your ult depending on your opposing hero. Rylai scepter with swiftness boots allows you to really get kills easily. If you have questions about the build, I probably forgot to add something.
