Hey everyone, this is my way to build akali. Hope you like it.
Please comment.

Pros
Very good at ks
If you are feeded enough you cant go down
Great farming skills
Great escaper
Good hunter
Cons
Need very much energi to use her combo
not very health strong if you dont buy any items with health

You need Majai's and Occult if you get feeded by the other. Penetration shoes to kill them fast.
Hextech to life steal, spell vamp, damage and ability power. Rylai's to get health and slow them. The hat so your ability power is raised very much.

Twin Disciplines
Upon obtaining 20 additional ability power, Akali's hits deal 10% bonus magic damage, increasing by 1% for every 5 ability power gained thereafter.

Upon obtaining 10 additional attack damage, Akali gains 10% Spell Vamp, increasing by an additional 1% for every 10 attack damage gained thereafter.

Mark of the Assassin
Akali spins her kama at a target enemy to deal 50 / 75 / 100 / 125 / 150 (+40% of ability power) magic damage and mark the target for 6 seconds.

Akali's melee attacks against a marked target will trigger and consume the mark to cause 50 / 75 / 100 / 125 / 150 (+40% of ability power) magic damage and restore 20 / 25 / 30 / 35 / 40 energy.

Twilight Shroud
Akali throws down a cover of smoke that lasts for 8 / 8 / 8 / 8 / 8 seconds. While inside the area, Akali gains 10 / 20 / 30 / 40 / 50 armor and magic resist and becomes stealthed. Attacking or using abilities will briefly reveal her.

Enemies inside the smoke have their movement speed reduced by 14 / 18 / 22 / 26 / 30%.

Cost 80 / 75 / 70 / 65 / 60 energy | Range 700
Crescent Slash

Shadow Dance
Akali moves through shadows to quickly strike her target, dealing 100 / 175 / 250 (+50% of ability power) magic damage.
