This is a Reference, you DO NOT have to follow it exactly, you may comment on my build AS LONG as you know what your talking about! Now if you leave suggestions for change in -->MY<-- build, make sure you have tried this build first. Or know what exactly your talking about!

Now then, lets get started

well i can give you many reasons, but lets go with three.
1. who doesnt like a ninja squirrel who can turn into a ball of lighing and blow stuff up?
2. this build focuses on Defence, since he has a lot of AP already, sacrifice some so you can take a Gank, common sense right?
3. HE'S A ****IN LIVING TASER DUDE :D

Kennen is infact a ninja, Ninja translated from Japanese means Assassin. Naturally Assassins rely on the element of surprise! Well Kennen was designed to do the opposite, He is used to get in the opponents face, and constantly disable them. I use the combo E+W+Q, and for tough to kill tanks E+W+Q+R.

1.Greater Quints of Vitality for that extra boost in survivability, these are replacable for Qunits of Potency, and Quints of Force.

2.Greater Mark of Insight provide that extra boost of Damage, ignoring a certain ammount of Magic Resist. VERY good to have as any AP character!

3.Greater Glyph of Force are for a better ammount of raw AP, and anyone that doesnt know what that means SHOULD QUIT WHILE THEY HAVE THIER DIGNITY (lolz jk Ability Power is bonus damage in green parenthasese in your skill description, sometimes skills use lets say 60% of maximum AP, so thats what.... 280.524 + whatever your skill deals.)

4.Greater Seals of Focus, what do i need to say? Kennen has some decently long cooldowns if you spam his abilities like i do, this helps A LOT! You may not see a difference with anything other than Greater Sealse of Focus

IF you do NOT use Kennen at all, and dont plan on it, then forget about even commenting, or considering a build for him, this is designed SPECIFICALLY for Kennen Users who want to be able to survive a 5 vs 1 Gank. The downside IS that my build is VERY expensive and you may not make it out alive if they can stun you BEFORE you flash out. Keep this in mind, as i take no responsibility for a loss.
