I don't have an item set link for this build on hand, sorry. You can build an item set to your liking in the game client by going to Collection -> Items.

Q W and the W empowered attack gives you a stun. If it's a melee champion who engages on you (or you're all-inning), you can use E Q and W. You'll win trades against basically any champion if you can stun them and disengage before they can return damage.

It's very rare to hit two Qs in a row (people will play around the minion wave and won't give you the chance). When your W-empowered attack is up and you don't have to last-hit immediately, that's a good time to look for a trade.

Early game (esp against melees) you can just chip away at their health bars with Doran's Blade auto attacks. You don't necessarily have to hit abilities, but any Qs or Ws you can hit obviously helps.

Energy management shouldn't be much of an issue unless you use E and don't hit anything to get the energy refund. You can't really oom yourself with just Q and W. Try to tag something with E when you can. If you can't tag anyone with E (like you used it to escape a gank or something), you'll just have to wait a bit and play safely until you get the energy and cooldown back.

Lmk if you have any other questions.

It really depends on the champion you're playing. Mercury's Treads are a good early buy against him as any champion. If you can trade with him when his Q is on cooldown, when you're behind minions and/or when he doesn't have his W empowered autoattack ready, you're less likely to be stunned for free. If you run at him when he has everything up, you're pretty much guaranteed to get stunned.

As a tank, you mostly just need to focus on getting some early magic resist and going even in farm. You aren't going to solo-kill a Kennen as Maokai unless he makes some huge mistakes, but you can probably kill him with the help of a jungle gank. Otherwise, just going even in lane should be fine.

As a ranged champion like Quinn or Teemo, you'll want to get a minion advantage and slow-push the wave. Trade with him when you have minions to block his Q and you should win if you have the minion advantage since Kennen's basic attack trades aren't as strong on their own. Kennen has kind of ****py waveclear early so you can often push him in if you're ranged.

As a fighter with mobility like Irelia, check out this video from SkillCapped. The whole video is worth watching, but the important part is at the 5:00 mark where they show a window where the melee champion can fight the ranged one when they're being pushed in. You want to fight when the wave is closer to your tower and there are only a few enemy minions.

Thank you Prizm. <3

Depends on matchup. Kennen has a pretty strong early game, especially into melee champions, but a few like Irelia and Renekton will out-trade you really hard if they can get to you and hit their abilities. Ideally you should be harassing a lot and only taking a bit of damage from enemy minions.

Against ranged matchups, you can trade when your empowered W basic attack is up or when you can land a Q, otherwise you'll usually lose trades or go even at best. If you have more minions than the enemy, it becomes a lot safer to trade, so look for more aggressive trades when you're pushing. Just remember to ward and watch for the enemy jungler.

Against squishy enemies keep in mind you have a lot of kill threat with your ultimate, so if you're against a Quinn or something and have trouble harassing her, you can just farm and wait for your jungler to gank and/or wait for 6 and all-in her with your ultimate.

Yep, it's pretty good into squishy champions that are difficult to trade autos with, like Teemo and Quinn. Basically if the only thing you'll be doing is farming safely (with maybe an occasional trade) and then all-ining with your ultimate, Electrocute is the best keystone for that.

Definitely not worth it on Kennen. If you want a keystone with better all-in, try Electrocute.

Edit: I totally changed my mind on this later, haha.

You can get a lot of points by keeping guides updates and reaching high guide scores. Commenting on guides (and replying to comments like this one) also nets you some tickets. Don't worry though, I'm not actually eligible to win the giveaway, haha.

Thanks for your comment, I'm glad you're having success with Kennen. I agree that he's a terrific team fighter! :)
