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.
This is still a work in progress, Mostly built this to look at summoner lvl 30. As you can probably see I focus on attack speed to add stacks of poison and dot champions to death. The items are in the order i usually purchase them. There is much room for improvement and constructive criticism is welcomed.
