Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
======>> Sorcerer's Shoes - One of the most important things for Kennen in the beginning, is shoes. The Sorcerer's Shoes gives Kennen 20 Magic Pen. and Enhanced Movement 2. It's great if you can get these as fast a possible so Kennen can get away or chase enemies faster.
======>> Rylai's Crystal Scepter - This is the next item to get. It gives Kennen 500 Health, 80 Ability Power, and every spell she uses, she slows her target. Great item to start with.
======>> The Black Cleaver - I choose The Black Cleaver because its a great item if you are working with a team champion. It gives Kennen 30 Attack Speed, 55 Attack Damage, and all physical attacks reduce the targets armor. Great item when your with a group trying to take down an enemy champion.
======>> Rabadon's Deathcap - The Rabadon's Deathcap is a great item for Ability Power. It gives you 155 Ability Power plus30% Ability Increase. I normally get two of these to make Kennen's Ability Power skyrocket.
======>> Abyssal Scepter - The Abyssal Scepter is a fairly decent item. It gives you 70 Ability Power, plus 57 Magic Resist.
======>> The skill order differs from what type of champion you are fighting against. If you are fighting against:
===> Someone close ranged: Try to up the "Lightning Rush" so you can get away quicker if he/she tries to charge you.
===> Someone far ranged: Try to up the "Thundering Shuriken" so you can have a far ranged attack on them.
======>> At all times if you can up the "Slicing Maelstrom" do it. It's Kennen's most powerful attack.
