Kennen is a mage that uses energy rather then mana. Kennen is very squishy by heart, but takes up for this by being a high burst mage if built right. Kennen is one of my favorite champions to play and I am sure he will be one of your too.

Flash will help you open up with your ult or escape for danger. Ingite can make sure you get that kill you are looking for.

First off you are going to want to take Greater Quintessence of Potency to help you out with that high burst you are going to have. Greater Marks of Force will also help you with this and scale great mid and late game. you are also going to want to take Great Seal of Resilience for the armor sense you are a squishy. And finally Greater Glyph of Warding to also help out with your little squishy ninja self.

These Masteries will get you the most out of your AP burst ninja.

You want to max your Q first for max harrassment early on and it scales great late game. Max W next so you can get the most out of your passive. Finally Max your E last and grab your ult when ever you can. You want to open with a flash if you have it up and go right into a ult. then you want to use your E,Q,W then ingite for max burst.If you do not have flash up you want to lead with a E following a ult right after with a Q then a W then ingite for max damage.

Getting the items listed will help you be able to get the max burst out of all of your spells plus give you some defense so you do not die as fast.

Kennen is a very fun high burst mage to play that a think everyone should pick up right away. If this guide help you let me know by leaving a comment below and suggest tips on future guides so I can always improve.
