Pros:
- she is killer of ranged carries like Vayne or Ashe
- invis from Twilight Shroud
- with my build high life steal from both spells and melee dmg
- big burst
- easy running away
- can go after many heroes that others may not get ( Kassadin, Ezreal)
- Mark of the Assassin restores energy

Cons:
- low HP
- silence will disable you hardly
- can be easily killed wiht AoE skills
- if you enter the teamgiht teamfight you may do nothing and just die
- need to always have stacked 1 stack of ulti
- high cd on Twilight Shroud

Most of Akali players do magic pene and ap runes but with this build you can easily go solo 1vs2 or mid. The only thing you can change is change seals and other runes but to still have 10 attack dmg and 20+ ap with Amplifying Tome.

21/0/9 but u can still go into defensive build - but imo it's worse. In defensive build try to make a lot of ap coz it will be hard for you when u wont do 1k dmg on few combosin late game.

Boots- as you may see there isn't any better than 1st boots in item purchase list but you shouldn't think youu do not buy any shoes.
Normal game:
- Boots of Swiftness or if you are new to LoL buy Mercury's Treads
Ranked Game:
- Mercury's Treads if enemy team has got many disables or Boots of Swiftness if you go solo lane or mid

What to do after Lich Bane?
It depends mostly how are you playing and how is your gameplay going on. If you are hardly focused but Zhonya's Hourglass if not Rabadon's Deathcap. Remeber that you can also buy different items like Void Staff if enemy team is armoured (magic resist) hard.

I pick Flash and Exhaust but if enemy team has got:
- 4-5 disables you can pick Cleanse
- high hp regen or life steal take ignite
- if your team hasn't got any Teleport and you are going solo top or mid pick it

Till u will get 6th lvl you may not be able to kill many heroes but you are stilla ble to harass them ;). Following this guide gives you a lot of dmg from Mark of the Assassin so you should try to harass your enemy and even try to attack him with melee when he's got Mark of the Assassin on him.
When u will get ulti combo is pretty easy - use Mark of the Assassin targer -> use Shadow Dance -> auto attack -> Crescent Slash and then repeat everything (ofc you can still use all the stacks of ulti before using Mark of the Assassin again).

If you play versus ranged lane you can last hit with Mark of the Assassin but remember to harass enemy little bit too. When u will get higher lvl its very easy coz you will be doing high enough dmg with Crescent Slash and Mark of the Assassin to farm catapult or mages.

Akali isnt very good at begging of team fight but mostly for killing low hp but high dmg heroes ( Kassadin or Ashe for example). But if your team hasn't got any initiators then go 1st then Twilight Shroud wait, if you are low hp try to run away with Shadow Dance on minion and then fast reg and go into teamfight.

Akali is very nice hero, mostly taken for killing carries and other low hp heores but she can be also good initiator and support ( but not in for example baby-sitting way).

The only thing u should be aware of it that enemy team can put Vision Ward inside your W and you will probably die. It goes same way with Oracle's Elixir - youu must fastly kill carrier of Oracle's Elixir or you will be seen and you won't do much. And the last thing is that few heores can see you even when they haven't got any oracle or wards - Twisted Fate's ulti or Caitlyn's traps (if you will run on them).

If you will find any grammar or another mistakes I apologise you, but I'm not english ;).
