AP Kennen is my favorite champion in the game, been playing him for a few months now, His burst damage, aoe stun, and mobility is completly game changing. Many people underlook him, exspecially since his nerfs a few weeks ago. If built correctly Kennen can absolutley carry and win games for his team.

I always, always get FLASH, IGNITE, Ignite works so well with kennen and lightning rush. Can rush in, ignite and get out. Also flash ulti with kennen is just so deadly. flashing into the middle of a team fight and immediatly lightning rush, ulti can devistate a team.

9- Marks of Insight- Magic pen is essential on any AP carry
9- Seal of potency. The Flap AP is amazing early game, helping you get fed
7- AP per level blues- Little early ap lots of mid/late AP is amazing on kenn
2- Flat ap Blues- Helping you get enough AP to devisate oppenents at level 1-3

Many people may crit this but the ap is so essential to destroying your lane and getting fed. I rush into Rylais so i dont need the health per level runes. With my first items i usually have 35ish AP which can win a lane easy as kennen.

Pros
Amazing burst
Short Cooldowns
Variety of builds
Situational stun
aoe stun


cons
Has to be in middle of team fight
Needs some health/resistences
Often focused
Burns through energy fast

I hate not going mid or solo top as kennen. He needs to farm and harass an enemy early game. I always mid as kennen, Always. You can last hit with your Q so easy and harrass with it as well. Great mid and solo top champion.

[*] Rylais Crystal Septer is alaways the first item you should get. The slow from it makes getting away from kennen impossible without wasting summoners. From there i finish my boots and go to deathcap. AFter deathcap its all depending on the team. If you are getting beat by an AD taem then get HOURGLASS immediatly. If an AP is your issue get Banshees or the AP/MR item that i cannot remember the name of. Finish with some magic pen and another Tanky item and you will be unstopable.

Masteries are all dependent on you. I always go 21/9/0 though because i play so aggresive i like the extra damage. But tank speccing kennen is very good as well. I get the dodge because normally as Mid kennen you will be playing an AD carry such as cait or ashe so the little bit of dodge is crucial and the movement speed is even better.

I play kennen in ranked every chance i get. Im 80 percent with him in about 200 games. I hardly see him in ranked and i just stomp people

Kennen is an Amazing carry who is actually due for some buffs. He will only get better so now is the time to learn him and master him
