When this champ was released I played numerous ranked and draft games with the champ and I don't understand why people feel the need to play this champ in every position but adc. Adc Kai'sa is actually broken especially with the right build. This champ feels like your playing Varus but with much more range and burst capabilities. Here is my guide on building this burst heavy adc.

For runes I take what I have listed on this build. I have tried other builds but none seem to compare to this one. A lot of people have questioned my choice of Ultimate Hat, I have to say that late game it helps your ult's cooldown so much so you can start jumping from enemy to enemy during teamfights, it is also a great way to chase down low health enemies and make some good escapes out of bad situations.

Personally I like to start by maxing my W first when I am against poke heavy champs bot lane. When up against less poke champs I usually max E so that when I do have to engage or disengage the ability is used to it's full capability.

When team fighting with Kai'sa it is best to play her like any other adc in a teamfight, STAY IN THE BACKLINE. Even though she feels like a chap you can run into a 2v5 and win, that will not end in your favor unless you are majorly ahead in kills and cs. Kai'sa is shut down by any form of cc so it is important to dodge those enemy cc abilities in teamfights using your E to get the extra movement speed or by using your R. Try and position yourself in a spot where you are getting your passive off on the most champs as possible, with Runaan's Hurricane this shouldn't be hard. I have won many 2v5s and 3v5s as Kai'sa because I kited and activated my passive over and over on the enemy team.
