Akali is one of the best champions in the game. However, there aren't too many people who can play her that well, so in this guide, I'm going to attempt to teach you guys a little bit about Akali. I'm not the greatest player, but I'm going to try and share what I know. This guide won't be that in-depth, but if you want to read a very in-depth guide, you can click this link:

I worked pretty hard on it, so please, leave a comment!.

First, we take a point in Mark of the Assasin: This skill is very useful in early game skirmishes, and there's many times in which I killed both of the champions in a lane, especially with the damage it can do after you hit the "Marked" champion. Max this as soon as possible.
Then we take a point in Twilight Veil. In my opinion, this skill is one of the best "W" skills in the game: You can farm very efficiently without champions like Caitlyn harassing you, and you can juke, this increases Akali's survivability by a lot.
For the third skill, Crescent slash, we will put a point that whenever we can.

Akali's ultimate really makes her very unique and very useful in a team fight, especially since you get a stack by getting a kill or an assist. Chasing almost isn't a problem for Akali, because you can easily chase them without any problems.

In a team fight, you want to try and be in the back, going in and out with Shadow Dance doing a ton of damage and going back. Being a burst champion, Akali really isn't a tank, and you want to stay alive as much as posslbe, because you are many times one of your team's many sources of damage.

In a fight, you want to use this following skill sequence:
Q to first mark them if you can
If theyr're running you want to use R to chase them, autoattack, and E
If they're staying in the fight, you want to throw down your veil because the veil can reduce much of the damage and you can get away easily.
Then use E>R>Q and so on to burst out a ton of damage.

Ignite helps you get those early kills and kill off stragglers, which you really need. Flash is meant for you to get away quickly, and setup your veil, wait for teammates, or run.

However, if you don't have flash, Ghost is an okay replacement, but it really isn't nearly as effective, because flash does the same thing and you can juke them. Ghost doesn't do that as well, and Shadow Dance is a lot more useful than the other advantage Ghost gives.
