Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is the way i play Kennen.... VERY FAST, CAN KILL TURRETS.....
some things that sometimes get changed are:
-on the rare occasion that you get squelched in the first 5 min, replace Mejai's with kage's lucky pick, and sell it off when you run out of space in your inventory. replace with anything that's not Mejai's.
-If I'm dying alot i spec into lightning rush a lot faster.
-If I'm not killing enough, instead of Mejai's i replace with Lich bane, making this build have 2 LB's
-If the opposing team sucks at focusing me i get abyssal scepter instead of a second Rylias (the game almost never goes that long)
-Some times instead of attack speed runes i replace them with AP runes. its just enough attack speed so your no waiting on it when you proc you LB.
-Some times I run with ghost instead of Teleport, but that's rare.
Early: this build is good for lanning as well as midding, but if you lane your going to want to get giant's belt and then get sheen, then finish both of them, that way you can kill turrets fast and get to ganking fast. start is heavy harassing with T. shrunken, also use it for last hits, if your opponents are aggressive instead of surge take rush. try to save your surge for 3rd storm counters, it really helps. don't be aggressive, let your opponents over extend when there tired of getting hit by t.shrunken.
Mid: by this time you probably have Rylias or sheen if your lanning, keep farming hard you aren't ready to kill much yet, unless you have 7+ stacks on Mejais. keep your eye open for when minions push to turrets, that's why you have teleport. kill turrets using sheen. this will keep the opposing team from pushing but it makes you primary target for ganks, which is why you have LB and Rylia's.
Late: Late for kennen is when he has started saving for Zohnya's, or when you have like 13 stacks on Mejai's, then team fights are relevant to you. if the game goes much longer then im shocked but at this point you can 1v1 with anyone by kiting them. or in team fights try to run in about 3-7 seconds after the fight starts. NOT CLEAN UP, clean up shows after players are being scattered, Kennen shows up after the first 2 ultys. if your playing clean up your a ****, and your team should tell you so. and if you see garen, give up and rage quit, he still goes 1v5 and spins.
so thats pretty much it.... RATE!!!
