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.
Sooo here is some tips you might want to see:
1.Your mark is the most damaging thing of akali,you can harass easily as you are in the twilight shroud,
2.Use your ulti WISELY,save at least one of them to chase,
3.After you got guinsoo things will get better you will damage them 1/4 of their hp with your mark but it will be lesser in the late game,
4.You must make your shroud as soon as you land with your ulti you will get 50 mr and armor that will reduce the incoming nuke damage.
Have fun and good luck...
