Kai'Sa's auto attacks, Void Seeker and nearby allies' hard CC apply stacks of plasma. Applying 5 stacks of plasma deals % missing health magic damage. Additionally, Kai'Sa's auto attacks deal extra magic damage on hit, with this damage increasing per plasma stack. ADDITIONALLY, Kai'Sa can evolve her abilities upon reaching 100 of a certain stat (100 AD for Q, 100 AP for W, and 100% attack speed for E).


Kai'Sa's passive brings loads of mixed damage to her kit. She is able to dish out hard hitting physical autos as well as a bit of magic damage on the side, making it very hard to itemize against her. Plasma stacks are fantastic for finishing off and shredding targets due to the % missing health. On top of that, her evolutions are very potent powerspikes.



Icathian Rain - Q

Kai'Sa shoots out 6 missiles that are evenly distributed among nearby enemies, dealing physical damage. Minions below 35% health take double damage and non minions only take 30% damage from subsequent missiles. Evolved Icathian Rain requires 100 AD and fires 12 missiles instead, thereby increasing it's damage.


This is your standard burst ability that needs to be used at the right time in order to maximise damage. You need to try to be using this when the enemy has no allies around them in order to get all of your missiles onto them for maximum damage (when they are isolated). If you are looking for assassinations, Q is going to help immensely if the target is by themselves.



Void Seeker - W

Kai'Sa fires a long range projectile that stops at the first enemy hit and deals magic damage, while also applying True Sight and applying 2 stacks of plasma. Evolved Void Seeker requires 100 AP and applies 3 stacks of plasma instead of 2, while refunding 50% of the cooldown.


This ability is fantastic to round out Kai'Sa's kit, as it provides a nice chunk of damage, plenty of plasma stacks and can also be used as tool for catching out targets in conjunction with Killer Instinct. Void Seeker is very important to hit to apply those stacks of plasma which increases your DPS. It is also fantastic when fighting against invisible champions since it will reveal them. Overall, you want to be hitting this as often as you can. As for the evolved version, it is unlikely that you will be evolving this ability unless running an AP build, which is not covered in detail in this guide. However, there is a basic AP build which I have created at the top of this guide if you are wanting to try it out. Otherwise, AD DPS builds are more effective in the jungle.



Supercharger - E

Kai'Sa charges up for 1.5 seconds and during charge up, gains bonus movement speed but cannot attack. After charging, she gains bonus attack speed for 5 seconds. The charge up time decreases down to 0.75 seconds and bonus movespeed increases up to 100% based on your bonus attack speed. Evolved Supercharge requires 100% bonus attack speed grants 0.5 seconds of invisibility during charge up.


This ability is absolutely crucial to Kai'Sa. Not only does it increase her DPS with the attack speed, but its essentially your only mobility outside of Killer Instinct, and it is essential that you use this ability at the right moments to not only maximise your DPS, but also to gap close and avoid damage as much as possible. This is the ability that separates good Kai'Sa players from bad ones. I cannot stress how important it is to use this ability wisely. Furthermore, once you have this ability evolved (which you almost always will relatively early into the game), the invisibility it grants becomes absolutely imperative in ensuring that you stay alive, and it also makes for a very useful outplay tool. Learning how to utilise the invisibility granted from E will distinguish you from a regular Kai'Sa player to a Kai'Sa God.



Killer Instinct - R

Kai'Sa dashes at an extremely fast speed near an enemy marked with plasma and grants herself a shield for 3 seconds.


So this ability isn't exactly the flashiest ultimate out there but its something that is actually very important for Kai'Sa's identity and playstyle. Hunting down targets and appearing out of no where is one of Kai'sa's specialties, and this ability helps tremendously with that. You can pair it in conjunction with Void Seeker to pick off targets, but be careful when jumping in, as you don't really have a way out of the fight after you use it. Don't ever jump into multiple enemies at once, as that basically ensures your death. Instead, be patient with this ability, and use it for the shield, to close the gap or to assassinate given the opportunity.
