This Build is the best for me..first i try kennen full AD...but there isn't big damage with skills.Belive me Kennen can mAKE A LOT DAMAGE WITH SKILLS...second i try FULL AP..then i realize that i make dmg only with skills and no dmg from AD..for that reason i try Hibryd..

AD+AP
i think a lot what item will be great for first..and i realize that kennen is a real harras champion and got a lot of dmg with skills and normal atack in early game..that thing that kennen don't have early game is HEALTH..then i make this build and for 30 games i got 27
VICTORY and very very beauutiful stats...

This build is awsome becouse kennen is awsome in early.mid.and late game... a lot of damage a lot of health and lots of stun :D

And finaly this build in late game...
AWSOME AD DAMAGE
AWSOME AP DAMAGE
A LOT OF STUNS(AND MASS STUN IN TEAM FIGHTS)
ENOUGH HEALTH FOR MAKING A PENTA KILL
VERY FAST
HARD TO KILL
...Just op kennen


And for haters..don't repair my build..i try it enough and i'm pissed off from BUILDS LIKE ARMOR PEN MAGIC PEN...and the normal stupid builds... try something new stop playing with one type builds..
