Not Updated For Current Season
** Under Construction **
Feedback is appreciated!)
The rune layout I picked is still a work in progress. I usually go with AD/AS Kennen just because its a little less risky. So, the runes I have picked allow for a bit more survivability. Kennen's AP play style relies heavily on more HP, Dodge and perhaps even some magic resist if you choose to do so. Your opponents will focus you first every time.
Ignite and Exhaust are both excellent for early game kills/ganks. These will help you get your stacks quick. However, because Kennen needs survivability and will be focus-fired ALOT you may choose to swap out either one for Cleanse. You almost can never go wrong with Cleanse (with any champion).
This particular build assumes that you are going mid every time. It could work laning top and bot, but it works much better solo - you must out level most of your opponents. Make sure you max out Shuriken and Surge first these are great for harrassing early game and even later on in the match. You need to harrass and gank as much as possible so that you can get stacks on your book.
You can choose whatever boots to go with depending on the opposing teams composition. Boots of Swiftness is probably the best for running into team fights and using your ult and other skills.
I will be updating this soon...
