It is a whole new game masteries.

Heey my name is Giantwang
I made this guide becouse there were no new guides yet with the new masterys and spells so here it is

This is an solid build build if you can play with kennen you must play him more then once
and if you realy like it Thumps up and give a comment
Please add in your comment if you got some tips or anything like that.

Pros

-Not squizy
-Great farmer
-OP
-High damage output aswell begin mid as end game
-unkillable

Cons
-

I picked the runes becouse you can high defence stats from it at low level.

Marks:
The magic pen marks give you the magic pen you need and if you need some more (enemy stacking magic resist) then get an Void staff.

Seals:
The armor runes are well known in league I prefer them aswell with jungle, but that is not our issue now, I took the armor runes for the durability in the late game you will need.

Glyphs:

Magic resist runes are great aswell early as mid as late game, they give GREAT durability begin game in mid and its always AP carry mid so that is kinda nice

Quintesse:

Ability power is always nice great damage begin game you got to love it.

THE NEW MASTERIES!

I love them myself Like I said be4

I took this for best Cooldown reduction and AP so its kinda nice.

Best items for Kennen

I chose this so you get alot of durabilty on end game and aswell for health points.

This is the best skill sequinse that I come up with:

Lightning rush --> Electric surge --> Thundering shurikan --> Slicing Mealstorm --> USE Your Zhonya's hourglass!

I chose this skill sequince becouse if you rush in with your lightning rush you will get 50 Magic resist and Armor Great def
After that use Electric Surge becouse you will have 2 stacks on every one you hit with your lightning rush so You already have 2 Marks of the storm on your targets

Now you use your Slicing mealstorm and you instand stun every one wich has been hit with your Lightning Rush, So you pop your ult and you get an instand stun on every one and the all will get your full ult on them becouse they are all standing in your AoE stunned.

The spells I prefer are :
Flash Great initior for your skill Sequence
Ignite Gives you that little bit more dmg you will need
Ghost Also an great anitiator especially now that flash has been nerved.
Surge NEW ! I used it some times now its pretty nice becouse if gives you more AP and AS for your 2nd skill mark.

Availebol options
Teleport: good for solo top or if you want it I would replace it with ignite or Surge
Heal: It can definetly save you!
Cleance: I dont like it only take this in draft mode if you know you get an realy stunning team against you.

DONT TAKE!
Revive: It has an 9 min cd so I dont think it is worth the spell you better take ignite you can pop it 3 times in the same time.
Smite: Are you jungling? I diddent thought so
Clarity: You dont even have mana!
Clearvoyence: This is the spell for support and your an AP carry not needed for you !
Exhaust: This is the AD carry spell dont take it!

At a certain point in the game you are able to 1 shot a minion wave this is the way how to do it!

Lightning rush --> Electric Surge
And you got all the minions ( Aslong you have hit them all with Lightning rush.)

Kennen can be an initiator or a follow up Aoe dps stun bot. Look at your team comp and understand how you work in it. If you have an initiator then go in after him most of the time. If you don't have an initiator then its on you. You will most likely die if you initiate improperly or your team doesn't follow up. So always make sure your team is in position to follow you up. Also let your team know what you are doing, ping or tell them.

Kennen's job is to blow up squishies. So always been on the look out for squishies to initiate on and blow up with your combo.
