Most people just look at the skill build/item build and then try to play a hero, so if your wondering about the 16 items in my item build.. i'm just trying to show you step by step everything I do to get 20+ kills in any game. Now moving on to the beefy part of the guide.
Akali can kill almost any hero in less than 10 seconds, can escape 5 heroes with a simple Twilight Shroud/Flash, and is a great ganker starting from level 1 to level 18. She is really quite a simple hero, I got over 20 kills in my first game using her... barely bought her yesterday, haha! My guide will teach any of you guys that want to learn how to use Akali, the way that I think is the most effective way. If you have any questions/comments/ideas feel free to post in comments below.
Q: Why Exhaust and Flash?
A: Flash is great for a quick Twilight Shroud/Flash get-away. It can confuse an entire team that tries to go into the Twilight Shroud and chase you, getting slowed and wondering where you went. Exhaust is great for 1v1 or just early game ganking. You can easily kill a full hp hero with less than half with an exhaust, a couple of spells, and a twilight shroud if they try to run, more will be explained later.
Q: Is it better to get AD with Akali or Ap?
A: To be honest, I have never tried AD Akali, why? The skills speak for themselves, Shadow Dance/Lichbane, Twilight Shroud/Lichbane, Mark of the Assassin/Lichbane, Crescent Slash/Lichbane. No one can survive this. Even if they have a sliver of health left, Rylai's Crystal Scepter will slow them down enough for you to chase them and kill them.
Q: Isn't it better to rush Sheen first?
A: No, getting Metaj's Soulstealer in the beginning will eventually give you 180 bonus AP, our main source of AP. Sheen increases your base damage, although it would be good as we get Lichbane later, but getting your Metaj's Soulstealer first is the best way to farm hero kills for your Rylai's Crystal Scepter, with which you can easily get 20 stacks of Metaj's Soulstealer.
Maxing out Mark of the Assassin first is the best because this is probably your main source of damage as one q + lichbane attack can do an extremely high amount of dmge.
You only need one level of Twilight Shroud because all levels last 8 seconds.
Crescent Slash should be maxed second because it works great in conjunction with your ultimate, but still doesn't do as much damage as a Mark of the Assassin.
Getting AP runes will give you an easy first blood as your Mark of the Assassin will do a bunch of damage.
You should go bot if your on the top team and top if your on the bot team. A teammate
with a stun or slow will make your kills extremely easy as Mark of the Assassin will do huge amounts of damage.
