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 a quick item guide I'm throwing together after some impressive success using this build or variations of it. The basis for this build is the passive from Essence Reaver which grants cooldown reduction from crit. The Cloak of Agility grants you 20% crit and 20% cooldown reduction if you have essense reaver! That means with only two items you'll have 65 AD, 40% crit, and 40% CDR, which gives pretty ridiculous burst.
