Not Updated For Current Season
At first, you need to get the HP Pot and Doran's shield (Armor + Health regen) since right now AP will be useless at small amounts so no need to buy an amplifying tome as a starter.
Level 1 - Use the mark but keep your distance. If you mark them and they are close, attack and consume the mark, but make sure your ally is near you when you do.
Level 2 - Having gotten Twilight shroud. Use mark, then enclose your enemy in the shroud, then invisibly go up to them and attack then run.
Level 3 - Same thing as level 2 but when you go to physically attack them, you also use crescent slash.
Level 6 - Now you got your ulti! Okay first, use mark -> Twilight shroud -> Shadow Dance -> physical attack -> crescent slash -> return to shroud until cooldown is up.
Buy Boots of Swiftness afterwards, they will allow you to run faster than your teammates because usually they just buy something with enhanced movement 2.
Kill some more minions or champions and then get the rage blade.
After that buy the rylai's crystal cepter, then get the two rings, then buy the armor.
In the end, your Akali will be strong both in AP and in HP.
