Kennen, the Heart of the Tempest

Kennen is a spaztic yordle of pure amazingness. His lightning spells, when used correctly, can win you a team fight due to his single-target burst + stun and AoE burst + stun. Also, with his built-in Ghost spell Lightning Rush, the little bugger is a pain to get away from or chase. My build is a tanky AP build that nets Kennen amazing survivability while also letting him destroy enemies.

Let's get a little background on his abilities first.

Automatic Passive: Mark of the Storm

Kennen's abilities add Marks of the Storm to opponents. Upon receiving 3 Marks of Storm, an opponent is stunned and Kennen receives 25 energy.
Kennen is built all around his Marks of the Storm. This is his only real CC and is situational, but easy to obtain. All 4 of his skills put a mark on an enemy and his W skill can put 2 on someone with its passive and its active.

Q: Thundering Shuriken
Kennen throws a shuriken that damages the first enemy it hits for 75/115/155/195/235 (+0.66) magic damage and adds a Mark of the Storm.
Spammable, but easy to dodge, this is Kennen's longest ranged way to apply a Mark of the Storm. This is great to grief enemies with before a team fight and to prematurely apply Marks of the Storm.

W: Electrical Surge
Passive: Every 5 attacks, Kennen deals magic damage equal to 40/50/60/70/80% of his attack damage and adds a Mark of the Storm to his target.

Active: Surges electricity through all nearby targets afflicted by Mark of the Storm, dealing 65/95/125/155/185 (+0.45) magic damage and adding another mark.
Your early-game ultimate griefing, this skill's passive is annoyingly situational but amazing. Before roaming, try to have the passive on-hit Mark ready for use.

E: Lightning Rush
Kennen moves very fast and gains the ability to pass through units, dealing 85/125/165/205/245 (+0.55) magic damage and adding a Mark of the Storm to any hostile unit he passes through. Kennen is refunded 40 energy if he passes through an enemy while using this spell, but can only gain this effect once. Lightning Rush deals half damage to minions.
Kennen's expensive built-in Ghost, this skill is amazing to get around with but also to farm and kill with. Be careful, though, because it costs over half of Kennen's energy.

R: Slicing Maelstrom
Kennen summons a magical storm that deals 80/145/210 (+0.33) magic damage to a random enemy champion near Kennen every 0.5 seconds. This storm attacks up to 6/8/10 times and cannot hit the same target more than 3 times. A Mark of the Storm is applied to enemies on the first bolt they are hit by.
This skill tends to cause mass chaos and make enemies go wild, making it fun and effective. Your best time to use this is after you've Lightning Rushed all the enemies and used Electric Surge. This will cause a huge AoE stun and nuke on all enemies that were hit by the previous two skills (pure win).

Summoner Spells
Next up are what summoner spells you should take when playing my Kennen build.

Spell 1: Ignite or Cleanse. This is all dependant on your playstyle preference, but I always go with Ignite cause I'm so offensive with him.
Spell 2: Flash. Duh.

Due to Kennen being dependant on Energy instead of Mana, his masteries are a little wack compared to other casters.


Archmage's Savvy: 3/3
Deadliness: 1/3
Alacrity: 1/4
Sorcery: 4/4
Blazing Embers: 1/1

Kennen's item build varies slightly depending on the situation, but it's generally the same.

General Items
Doran's Ring (Always) [Sell at the end for Zhonya's if need be]
Sorceror's Shoes
Rylai's Crystal Scepter (Always)
Sunfire Cape (Always)
Sunfire Cape
Zhonya's Ring

Situational Items
Abyssal Scepter: If you need Magic Resistance.
Guardian Angel: If you're dying too often.
Mercury Treads: If there's lots of enemy CC.
Mejai's Soulstealer: If you're stomping the enemies hardcore.

In-game Tips
NOTE: With this guide I am assuming you are soloing mid. If not, things will be slightly different.
NOTE: Items with []'s around them means that you may be able to afford at the time if you're doing really well. Items with ()'s around them are Situational Items.

Early Game
Auto-attack creeps that aren't in danger of dying soon to charge up your W, then hit your enemy solo-midder with the Mark attack then activate W. Do this anytime you can safely do so. Be sure to be last-hitting as many minions as possible while harassing the enemy as well. Avoid using Lightning Rush unless the enemy gets cocky and leaves him/herself open for a death. Try not to spam Shuriken unless you have a good shot. If you start getting harassed yourself, stay back and just farm. Try to avoid having to recall until you have at least 1460 gold to buy a Giant's Belt and Boots of Speed.

Items: Doran's Ring, Giant's Belt (Mejai's Soulstealer), Boots of Speed, [Amplifying Tome].

Mid Game
Start roaming and ganking as you see fit, but don't let mid lane die in the process. Only ever take golem/lizard if none of your allies need it/it's more useful for them. Help with dragon when needed, but don't try to solo it unless you have your Rylai's. By now, you should be able to farm whole creep waves easily by using Lightning Rush --> Eletric Surge then last-hitting all of them. Contine farming and/or roaming until the all-mid showdown begins. Once it does, be sure to constantly snipe enemies with your Thundering Shuriken when the teams aren't in a huge battle. When the battles do commence, try to stay back until the initial blasts have gone off, then Lightning Rush in, use Electric Surge, Ignite an enemy while doing so, pop Maelstrom, and spam Shuriken + auto-attacks on the target. Use your skills as needed to finish the enemies off or get away.

Items: Sorceror's Shoes (Mercury Treads), Rylai's Crystal Scepter, Sunfire Cape, [Abyssal Scepter / Guardian Angel / Sunfire Cape #2]

Late Game
By now, your damage will have dropped off a bit because of you only have 2 (3) AP items. Don't fret! That's what the Sunfire Cape(s) is(are) for. You should be a tanky kamikazi bomb of pure destruction and be one of the main initators for fights now. Lightning Rush in and use the regular skill combo while you laugh as they aim at you instead of your carry(ies).

Items: Sunfire Cape #2 (Abyssal Scepter / Guardian Angel), Zhonya's Ring.

This is my story.. I mean Kennen guide: use it well and enjoy being the yordle of chaotic death and destruction.

What do you think about haunting g. + sorc shoes + magic pen runes + mastery ?
because in this case you can do kinda full damage with ~ -60magic pen.
Well i must agree that very very important thing for him is something with survivability + AP like rylais, but with sunfire doesnt he become kind of a tank ? i'd rather replace it with some AP things.
Oh and mejai is so situational, its nice to get it early game, but just so way too situational.

I like this build. My build is similar to this but is missing sunfire cape. I may have to try that sometime.

So how do you use Kennen's skills? Do you have a specific rotation? Or priorities perhaps?

Why Doran's Ring over Shield?

Last time I checked, some Health Regen and Armor is better in the laning phase than a tidbit more damage on your abilities.

Other than that, the build is fairly solid.
