My build to Akali where i rarely receive less than 10 kills. Even when my team sucks ill go 19/7, 21/6, etc. I hope you enjoy it and do great!!!

The main goal of my runes is to proc both of Akali's passives at the beginning.(i dont get the ad per lvl seals but thats all the maker had XD). If you finish the rune build you could get boots of the start since your passive is already up but i havent finished the runes yet because I'm only level 25.

I recommend you go ahead and call mid when using this build. What i do is last hit minions with your "Q" move and throw down your "W" when they get too close to your turret. If your enemy in mid is becoming very aggressive then throw down your "W" to keep them away. If they are stupid enough to come in it attack them with your "Q" auto attack "E" combo and they"ll probably back off but if they dont your passive spellvamp should get you back in the fight. Akali is a great mid that people often don't see as in:

She doesn't have mana
You can get a good bit of your health back with hextech revolver by farming with "Q" auto attack "E" combo in a group of minions.
And the mmental aspect of your "W" move keeps champions at bay (Smart ones at least).

Akali is a great if not the best chaser in the game. When you receive 3 stacks of her ultimate and you have more or the same amount of hp as your target jump to them with your ultimate then hit them with your "E" move and throw your "Q" on them and jump to them again and activate your "Q". After this a squishy carry should be half hp and you should do it all over again and applying ignite if they are near a turret or teammates etc. With this you should be able to successfully kill a squishy carry. Akali is an amazing anti carry. I usually find myself skipping out on team fights to go straight for the squshiest people ex. ashe ryze sivir. I do not recommend targeting a tank with more than 3000 hp unless you are with your team because ultimately your just wasting your stacks of your ultimate because they will most likely get away. Also if you find yourself dashing accidentally into their team trying to target someone about to die, you use flash. I usually throw down my "W" to confuse them then flash through a wall. If your flash is not available i recommend throwing your "W" into a long bush and trying to juke them. The enemies almost always go the way you were running in the first place so then you go the other way.
