I do like the Deathfire's Grasp idea. I had mis-read it and thought it did damage based off Mana, not AP. Thanks for the idea.

Basically, unless you SPAM shuriken, every time it is up, as soon as it is up, then CDR isn't worth the price as a damage tool.

If it's just for Ultimate, then you should be looking towards DFG or Morello's Evil Tome instead of Nashor's Tooth.

Nashor's gives you too little utility/damage for it's cost.

Personally I don't find his energy all that limiting unless you just happen to not hit a target with Lightning Rush. I have not ever found Kennen's energy to be a problem when it comes to using his abilities as long as one uses them wisely. The point of AS on Kennen isn't to be groundbreaking and change the game because I'm auto-attacking faster than a person can count. I'm just using some splashed in AS to get Kennen more hits so that he can get his Electrical Surge passive off more and get a free Mark of the Storm without using energy. While I can see Nashor's Tooth being a bit too expensive, I haven't played enough games, only 2 with Malady now, to find the cheaper price better. I wikk probably try Wit's End on Kennen as well to see how it goes.

I will make this argument against Nashor's Tooth (as apposed to an argument for Malady.)

Because of the Energy mechanics that Kennen is limited by, he can't support cooldown reduction unless his energy regen is also buffed.

IF you can get Blue buff and/or Baron buff, then yes, you could support CDR, but otherwise, you just run out of energy if you use Shuriken off cooldown (The MAIN benefit to CDR.).

It might be nice for the CDR on ultimate, but Nashor's is WAY too expensive to justify the extra ultimates.

If you NEED the CDR, then blue buff should be the source, not Nashors.

If you really like the attack speed buff, i actually really recommend to get Wit's End.

It's cheaper than Nashors, gives you alot more power to your auto attacks, makes you tankier, you lose 50~ AP, but you end up tankier, and your auto attacks hit harder.

Then again, i don't recommend AtS at all on Kennen.

Well that's two people. I'm gonna try Malady and see how I like it. Thanks for the input.

Nice guide. However Kennen uses energy, and doesn't benefit from the mana regen that comes with Nashor's Tooth, and would work better with Malady. Other than that, I see no flaws in your item sequence.

Liked the guide, fix the skill sequence though, you have 6 points into Thundering Shuriken and 2 points into Slicing Maelstrom. Also clean up the wall of text in the playstyle section with the coding for the skills and such.

Thanks dude! I'll have to try using a Malady on him the next time I run around as this guy.

haha, I like it. AS hybrid kennen. Throw in a malady after nashors and I think you'll be pleasantly surprised. GJ though +1
