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.
Akali can be a very annoying champion to play against. After level 6 she is nearly impossible to get away from. She is a little weak in early game and if built right she is ridiculously good in late and mid-game. Her passive suits her to be a hybrid ability power / attack damage champion. This build allows you to get the best of each.
High movement speed
Great attack damage and AP to take advantage of her passive
Good armor and magic resist
Not very high health or health regen
