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.
So i have been playing with Akali a lot lately and when i went to find a build for her, there wasn't really any good ones and so i built this one and it works wonders. this setup is really good for getting up to an enemy and killing them quick, she can even take on tryndamere if its 1v1. so ur game plan for slaying the enemy is get in range to to shadow dance someone and once u r right on top of them u quickly use Crescent Slash and then by the time u use this use Shadow dance again and by then u will have to wait for it to cool down and so use the Mark of the assassin on them and by that time u will be able to use crescent slash and so on... and they will be dead no problem especially if they had 3/4 health or lower
