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.
My Akali build. Works by starting with survivability (doran's for lifesteal and spell vamp plus health regeneration runes) and snowballs into insane burst. Very important to get amplifying tome as soon as possible, and as soon as you get sheen you can start ganking. Focuses mostly on ability power, rageblade is there to help pushing a ton. If the match continued after the zhonya's, I would probably replace doran's with a bloodthirster or gunblade to help push. This build has worked very well for me, as you can push to take down turrets and kill most people in a one on one fight.
