Suck at this game? Want easy wins? Then this is the guide for you. Just follow this guide's exact build order, play with some courage and not like a complete dumbass, then you will win every game!

Trust me, I am not a good player by any means. But with this Akali build, I was able to win games vs higher skilled player.

NEVER RUSH GUNBLADE. Since our runes and masteries are too manmode, do not rush gunblade, or else you'll be squishy as fack. Instead, rush rylais so you appear to be tanky because you have so much HP!! No one will even focus you because they will think you're a tank.[/color] Once your Rylais is completed, which should be around 15 minutes into the game, you can roam anywhere and get kills because of the Rylai's slow. With the extra HP, you can even tower dive bot lane if you have flash to get out safely.

This guide is good for ranked. Just kill everything with OP items. Once you complete lichbane, if the carry is hard to get to, you can use a combo or two on the enemy tank/offtank. Try to stay out of enemy vision when your team is grouped or pushing towers, you don't contribute much in a push anyways. Hide somewhere near, or behind your team until an initiation happens. If the enemy sees you before a fight broke out, they're more prepared to use their CC on you.

Pros: Can't lose with this build.
Cons: Might lose with this build.

Kill minions, run around the map after level 6 and cause trouble. Try to force objectives like dragon at around 15 minutes because that's when you're the strongest relative to your enemy. No one can 1v1 you at this point.

Akali's damage on minions: Before your first buy you can kill melee minions after it has taken 2 hits from the tower with 1 auto attack. For ranged minions, you will need to use E on them first, then you can kill it after it has taken 1 hit from the turret with 1 auto attack.

After you have a revolver, you can kill ranged minions after it has taken 1 turret hit with 1 auto attack without the help of E.

Getting CS pre-6 in lane is hard, but not impossible. Just use your Q to get last hits and shroud to walk in to get last hits or harass the enemy. When you see one of your minion is about to die, throw a shroud down in front of it, so that you can walk in and land a combo on the enemy. He have the choice to take one of your combo to the face, or lose that CS. What I see some people do with Akali is, they throw a shroud down where they stand, then walks forward to harass the enemy. WHAT THE HELL DOES THAT DO?? It makes you stealth in an area where you're safe, and then you step out of it, revealing yourself to harass, only to take a punch to the face. Don't be a noob, don't shroud like this. Be a mon, shroud ON, or BEHIND the enemy!

Never let the enemy free-farm, because he will become confident and harass you. Try not to take harass from the enemy, because if you can lane long enough to get level 6 and 1200 gold before your first trip home, you can return to lane after the first buy with your hextex revolver and 2-3 charges of your R.

If the enemy have offtanks like Jax or Udyr who dives straight for your ADC, try to put down some DPS for your ADC so he can kill it faster. Never let the enemy know where you are before a teamfight. Check the enemy's inventory before a teamfight to see who have pink wards. If no one have pink wards, dive straight for the ADC and put a shroud down immediately. It will force that ADC to either run back or die to you.

Splitpush: Once you get a deathcap, you can kill towers pretty fast. With lichbane, you can kill them even faster. Only splitpush if you are skilled enough.

Getting max DPS in lane: Once you've reach level 6 in lane, do not attempt to jump on an enemy unless you have at least 2 charges of your ult. In order to get the most damage in the shortest amount of time, try to throw a Q mark on the enemy without the use of the shroud (the best time is when they go for a last hit). Let that mark hang on the enemy head while your Q is refreshing off of cooldown. When your Q is about 1-1.25 second from finishing its cooldown, immediately jump on the enemy with your R, throw down your shroud and proc the mark with E. Right after the mark is detonated with E, throw another Q mark and proc that one with an auto attack and then press R on the enemy again. You can now safely walk out of your shroud with 1 ult charge remaining. The enemy should have lost about 3/4 of his HP if you did this properly. If you're sure you can kill him, then go for it, if not, wait for your shroud to come back and repeat.

Chasing enemy: When dueling or chasing someone, never use E unless the mark of death have already landed on them. Using E without detonation of a mark consumes all of your energy and deals no damage. Also, don't waste an ult charge on an enemy if you are in range to throw a mark of death at them. When you are in range to throw a mark of death, let the mark travel and land on the enemy before jumpin in with R and using E. A rookie mistake for Akali players to do is to jump in with R as soon as they throw the Q mark of death. They just end up appearing at the enemy and using E and an auto attack on the enemy before the mark even get to land on the enemy. If you jump in with R too early, by the time the mark lands on the enemy, the distance between you and the enemy is already too far for you to proc the mark. SO REMEMBER, ALWAYS WAIT FOR THE MARK TO LAND FIRST.

If you lose with this build/runes/masteries, then uninstall the game and burn your computer. Leave comments on how this awesome guide made it possible for you to carry with Akali to diamond. There should be no excuse not to win at least 50% of your games if you follow this guide. If you see any mistakes or bad advice, please let me know so I can fix it or tell you that your're a dumbass and don't know what you're talking about.
Anyways, I hope that you find this guide helpful and I hope that you learned something from this guide even if you decide to ignore it and go 21/9/0 Masteries with Armor+MR runes while rushing a gunblade. Just don't come crying when you teamfight and everyone focus you and you die faster than you can burst them because they CC you and you can't spellvamp with your silly gunblade.
