This kennen build will kill people in less than a second. It is taking kennen, a wonderful teamfighter, into an assassin. Best of all, he deal damage in aoe, so he can burst multiple people down. Also this kennen build has a hextech gunblade, so kennen will never die, and if he gets close to, he can just go into the jungle, kill 1-2 camps and he will be back to full health.

For the runes you're gonna want to go electrocute to burst down champions, then cheap shot, eyeball collection, and ravenous hunter. For the secondary runes you're gonna wanna go in the precision tree with triumph and coupe de grace. I chose these runes because it's the basic runes for ap assassins.

For the items, instead of going with hextech protobelt, you're gonna want to go with hextech gunblade instead. This is because of the healing it gives you, and because the ad synergises with one of the next items. After the hextech gunblade, you're gonna want to get sorcerers boots. After that, you're gonna want to go liandry's torment. This is because of the magic penetration to kill people faster, and because then kennen's abilities will burn. After that, you're gonna want to go guinsoo's rageblade. This may seem odd, but he has a high base attack speed, and also his auto attacks do lots of damage already and also it helps because of the ap. After that you're gonna want to go luden's echo. This is because of how kennen is very mobile and it'll help him do damage. The final item is of course rabadon's deathcap. This is to get a power spike in ap, and a great last item. It will keep you in the game when late game comes, because most assassins tend to fall off in the late game. This build if for you if you want to do lots of damage, and heal up as if you have lifesteal, and you kill people in less than a second.

Kennen's skill order is simple, just R->Q->W->E always. Even in the first 3 levels.

Just play like an assassin. High risk, high reward. Take chances, and just go in. If you stay back, you get poked down, and if you play safe, you'll never get any kills. If you get behind or feed, just farm or roam. Most of the time you should just farm to catch up, but if another enemy lane is behind, you most likely can successfully roam. Just make sure when you roam that your enemy laner isn't attacking your tower.

Because it kills them way faster, it's lots of fun, and most of the time, it works. Most games I do really good. And if I don't, I don't do horrible. This build has a higher winrate than kennen's normal build. When ahead, you snowball like akali. And when your behind, it's easier to catch up. This build generally has a higher damage output, and has lots of lifesteal because of the hextech gunblade. I definitely think everyone should use this kennen build because it works most of the time compared to the normal protobelt build.
