Well,let's be honest Akali isn't the hardest champion you will ever play,she is simple and strong and she can help you get out of ELO hell if you play her right.My tip for a beginner Akali player is to never be cocky as Akali you will be very strong if you get fed so do not dive into turrets or in 1v4 just to get a kill or even a double kill because you end up giving gold to 4 people.

Akali's early is pretty awful in my opinion the only thing you can do is stay passive and farm,you can last hit pretty easily thanks to your q and passive you can abuse your opponent's mistakes and can kill them a small combo to do good trades with Akali is to hit 1 minion and when you have your red aa ready then q your opponent use w for movement and consume your mark with your red aa and your opponent will be close to half hp because of your extra dmg of the mark and your red aa and your thunderlord.If you go against a hard matchup and pokes you a lot ask your jungler to gank

Once you hit level 6 the true Akali is born.If you can 1v1 your enemy midlaner then go for it with the classic combo(aa minion,q enemy,ult enemy,red aa enemy and then shroud if u want to dodge an attack or sth)if you cant 1v1 your enemy then do what you are meant to do,ROAAAAAAAAAAAAAM!!!! roam botlane to 100-0 the support and adc getting a double kill and trust me its very easy to double kill them.

Late game isn't your favourite part of the game.To solo carry as Akali you have to end it in mid-game but you can still do things in late.Your main focus is to kill the one who deals most of the damage whether thats the adc or the midlaner etc.
The main reason Akali is an op champ is because she snowballs very easily and very fast once you get a double kill in early you got fed but in late game your enemies are able to catch up and make you useless.Akali is a squishy champion and with cc they can destroy you so thats why you always buy zhonya's and guardian angel for the last item.If you get to late game and the enemies catch up you arent solo carrying anymore you want a team to help you win the fights while in mid game you can penta them all alone and you just need your team to absorb the damage

I play League of Legends since season 2 and being this old of a player is lame to still be gold 5 this is actually a new account because i banned the old one( :/ )
Im a mid/jungler main and thanks to Akali i managed to get to gold once again and no im not an otp Akali i play other champs too :D

Your experience as top Akali is much different than mid Akali,you will deal with lots of tank and strong offtanks that will make your life harder than dealing with a squishy mage or assassin.Personally i prefer mid Akali because you can roam any lane you want and you can easily camp your bot once you go 6 and assist your jungler anytime he wants to,Akali top can roam too but for mid Akali it's way easier.pre-6 never push your lane because if you get ganked you only have your w as an escape item and sometimes its not enough especially when you dont have flash.a tip to escape is to run towards their turret,make them follow you and use your ult to jump on a minion behind them.

Lot's of people will consider you a troll but they forget how strong Akali is.When you main Akali your favourite moment of the game is when you hit level 6 and you can roam so jungling is pretty much that.before 6 you cant gank pretty well except if the enemy pushes and your teammate has some good cc like stuns or slows etc. but once you hit level 6 you will just gank everywhere and get fed.if you cant gank any lane at all before 6 try to stay in your jg and clear the camps and counter jungle if you find the opening,if you cant gank farm a lot because you need it

Apart from the Relic Shield build the same like the mid build,same goes for masteries,runes etc.
Akali support will be always considered troll but its actually really cool,I recommend you play Akali support on normal games because its a big risk to play it in ranked games.
In early game as a supp just use the passive or Relic shield and try to harass the enemy as much as possible but without taking much damage from them,if u can't harass them then don't risk it.Once you get 6 you insta won bot if you are careful.Do not underestimate your enemies and always ward the bushes.Let your adc take a kill here and there and roam mid if you find a good opportunity
