T0 answer this question you must first ask yourself "how can I p0tatoe?" /jk

Kennen is a half ninja / half yordle =100% badass

This guide will provide you with a fun way to play kennen while still being able to do well ingame. This is also works well for the people who like to gank often.

Jump in, hurt them badly, gtfo(also, don't die). Rinse / repeat

Now I know most people will say "wtf n00bsauce. This item build is terribad" well you can GTFO. These items are all easily explainable.

First: boots of mobility. Kennen is slow because he has tiny legs. These boots help him go fast. Simple, duh. OR Boots of Swiftness (also makes you run like fast and stuff)

Static Shiv: Kennen is like 90% lightning so this makes sense to me (moar lightning.) Lightning + lightning = MORE LIGHTNING!!

Deathfire: nice nuke to have. Stun > Deathfire > Ult. GG FTW

Void Staff: Because AP pen. Duh

Rab's D-cap: Put a hat on, gain AP, ????, profit!!

Total cost: 12,000 gold This is for people who farm well enough and based on average time 25-35 mins for overall gold total.

Magic Pen. Makes abilities hurt more.

AP more AP dmg (duh)

AP see above

+6% Exp Why? Outlevel opponents lane. Rush to lv6; GG

Take attack speed (in Offense tree) because that last auto attack can be the diff between a kill and not a kill.

The rest are obvious. Also, the 1 in utl helps you chase pansies like garren / xin when you need to catch them with your Q or to get into range for your ult/w when your E is on CD.

See skills for 22/8/0 suggestion.

Skill order: R > W > Q > E.

Max W ASAP for good farming.

I usually run: ignite / flash but I also recommend ghost and exhaust. ONLY take exhaust if you want to put that masteries point from utility into offense tree (1 point for summoners wrath)

Yup. 22/8/0 OP

This is all from the official website: (I just re-posted for ease)

You can stun your opponents by inflicting 3 Marks of the Storm upon them.

Lightning Rush can be used to initiate fights with its energy return component, allowing him to use other abilities afterward.

You can land an initial Mark of the Storm debuff on an opponent with Thundering Shuriken, and then add to it with Electrical Surge.
