Through playing alot of Akali I have found you are often doing so good that you are always first to be attacked, this build leads to insane damage while still being able to tank towers, stand up in team fights and solo baron if you go for Occult instead of Boots (Tested and Proven). Start of the game buy buying a Tomb and a Health Potion. The reason behind the tomb is that the sword is all good for spell vamp, but for the first few levels do such minute damage that it is practically useless and the 14% more Phys damage is alot more helpful early game. If you have a good laning partner you should be getting first kill and hopefully second. As soon as you reach 800 gold recall and buy a soulstealer, you don't want all those kills your getting to go to waste do you?. After you have Mejai's it is a tossup whether or not to get Occult, if you are doing very well I would defiantly go for it and make boots the third item. Around level Six or seven you should start ganking, initiate with Shadowdance, right away Mark them, and make sure to always spam attack them while doing this or you risk the chance of not hitting them and igniting the Mark which is where your real damage comes from. by level 9-10 you should have about 10 charges with you and wrecking champs will not be a problem. One important thing about Akali is always take the Golem buff whenever possible, Why? Becuase it makes your energy regen freakin insane, and the c/d reduc is nothing to shake a stick at. This is rough draft at the moment and will get this cleaned up in a little while, but truly try this build and you will not be disappointed.
