Kennen/Strategy

Skill usage

 * can be used to detect enemies hiding in the brush, as a sound effect will play if it impacts a target.
 * is very effective for harassment. Taking more than one point in it early game allows you to harass the enemy really hard while not being in range to take damage.
 * Getting one level of and then maxing  allows Kennen to maintain 2  stacks on enemy champions, as well as effectively harassing them.
 * Using after players have 2 stacks of  is an easy way to stun.
 * Kennen is a great farmer if you use combined with.
 * Using to dodge skillshots and run away is a good idea.
 * can be used to initiate fights with its energy return component, allowing him to use other abilities afterward.
 * While in form,  cannot perform normal attacks, but can use all of his abilities.
 * can be coupled with the summoner spell to move at very high speeds, with Kennen's stun this is excellent for chasing.
 * can be used to get back to lane quicker.
 * After a team fight has initiated, use to apply marks to as many enemies as possible, followed by  and . This combo adds two marks initially, followed by one mark for the stun, and then adds an additional two marks, leaving any runners ready to be stunned with  . Alternatively, saving energy and waiting for a second  will result in a second AoE stun.
 * A good skill sequence to harass an enemy or to scare them off is, , and (if possible). The reason why this combo can scare enemy's is because it can stun or get ready to stun.
 * Kennen is a champion who relies heavily on combos. Some simple combos are: +  + (passive) +  - this combo works extremely well from levels 3-5 (ie before  is learned). At level 2, Kennen can do a  + (passive) +  combo to result in a highly damaging stun and a few auto attacks during the stun.
 * Once reaching level 6, Kennen gains the ability to stun an opponent twice using a +  + (passive) +  +  combo.
 * For this combo, wait the longest time possible between the (passive) (which completes the 1st stun) and your  (which completes the second stun) to regenerate Energy, land free auto attacks, and position yourself behind the enemy.
 * The key to playing well is learning how to chain his combos together to be able to land free damage on the enemy while keeping them in a disadvantageous position.
 * A good way to build Kennen is a balanced build, which will spread the damage out more efficiently with mark of storm. With all three skills at rank 2, Kennen becomes a powerful enemy.
 * is amazing for turning team fights around. It is key that his R is used as much as possible against multiple opponents, but only at the right time.
 * Kennen tends to be an initiator or to follow immediately behind an initiator thanks to . Using wisely in a team fight, in conjunction with  and, nearly guarantees a viable amount of energy gained from  because Kennen's cooldowns tend to end more quickly than Kennen's energy regenerates.
 * Remember that also provides you with a great boost of your armor and magic resistance meaning it can save you from fatal situations like Karthus'  or skills that do damage over time, notice however that it won't reduce true damage.
 * One of 's biggest strengths is his flexibility of item builds in any given situation. Kennen can easily be built either as an attack damage carry or an ability power based carry. He's also a very powerful top laner in both attack damage and ability power based builds due to his decent attack damage scaling and passive and split pushing ability because his  can serve as a good escape mechanism in sticky situations as well as serving a good pushing skill in conjunction to his  active.
 * Ability Power build strongly utilizes his, 's active, and . The ability power build brings more teamfight presence and large crowd control stuns on the enemy teams who tend to be grouped together. Because Kennen needs to be in the frontlines to utilize his ultimate, he needs to built a bit tanky in addition to ability power since he will most likely be focused on. The ability power build synergizes well with champions who have heavy area of effect damage (i.e. , , , and ) or dive heavy team compositions.
 * Attack damage builds are almost similar to an attack damage carry where he puts more emphasis on autoattacking because of his passive scales in attack damage and his strong self crowd control and utility ability with his, something that most attack damage carries lack with a few exceptions like  and . Because  uses Energy rather than mana, he has better sustain than many other attack damage carries except . Building  as an attack damage carry is recommended for those who have difficulty landing his , laning with supports who lack any forms of healing or sustaining the attack damage carry like , , , and , or team compositions who tend to focus on a single target. Keep in note that attack damage carry  tends to fall flat late game against other late game oriented attack damage carries like ( and ) because he is really reliant on autoattacking where his range is equivalent to  and lacks good attack speed/damage steroid unless he is fed early.

Build usage

 * Getting double early game allows Kennen to be a strong lane bully with the passive of  as well as give a little survivability.
 * and are effective items on Kennen. If Kennen is played as a caster,  is useful for increasing the amount of damage he does, especially since his  can be used every 4 seconds at rank 5.
 * can be very good with his, since you can get very fast to any opponent and slow him this way, and once slowed your target can be comboed easily.
 * It's recommended to build AP along with defensive items as Kennen's full combo requires getting close to enemy champions and therefore survivability will be a must during teamfights.
 * As is not a channeled ability, you can use it in conjunction with  or  for a powerful combo.
 * Giving Kennen is good for the passive effect of his  as it gives him some AP to deal more damage with spells.
 * Spell vamp items, specifically and its component, are extremely effective on Kennen during the laning phase, as Kennen can last hit with Thundering Shuriken to regenerate health. Because he uses energy and not mana, any amount of spell vamp grants him free sustain, which is extremely advantageous in the laning phase when fighting opponents who have no way to sustain or lack the mana pool/mana regeneration to consistently sustain themselves.
 * While a niche option, because of Kennen's high attack speed growth, a decent attack damage growth, and the utilization of his ; Kennen can effectively be built as an attack damage carry in a similar sense like . Items like, , , , , and can allow his  passive's  trigger more quickly. Because his  passive damage is scaled in attack damage. items like , , , and  are good items to utilize. The attack damage carry build path is recommended to players who are new in playing Kennen, or those who have difficulty landing his  skill.

Countering

 * Moving erratically or taking cover behind minions can hinder you from getting hit by his.

 * Quickly using a knockback on Kennen while is active can cause him to waste the ability. Be aware  is a common item on  to avoid such a possibility.
 * Kennen primarily deals magic damage. Investing in magic resistance items will reduce his damage output.
 * That said, Kennen can also be built as attack damage carry. Pay attention to his build to counter him properly. For example, reducing his attack speed will lower his damage and stun output.
