Kai'Sa keeps the hypercarry alive with peel and sustain. Enough Catch and Attack sits in the kit to punish a caught enemy before the fight starts. Passive Plasma stacks (max 5) on-hit/W-hit deal increasing magic damage and detonate a missing-health-scaling nuke on the final stack.

Dragons & win rate

Win rate when Kai'Sa's team secured at least one of each drake, next to the all-champion rate in that same state. Teams that take dragons are usually already ahead, so every champ wins more with them — the honest read is the gap, i.e. whether Kai'Sa beats the average team that also has the drake. Single-drake samples are thin; treat small counts as suggestive.

Innate - Living Weapon: Kai'Sa can evolve each of her basic abilities by gaining a set amount of permanent stats from items and stat growth, granting them additional effects. Evolving an ability causes her to enter a 2-second cast time. The upgrade is lost if the stat requirement is no longer met.

Innate - Plasma: Kai'Sa's basic attacks on-hit and Void Seeker apply stacks of Plasma to enemies for 4 seconds, refreshing on subsequent applications and stacking up to 5 times. Basic attacks each apply 1 stack and Void Seeker applies 2 stacks, increased to 3 if it is evolved. Her and nearby allies' immobilizing effects and polymorphs against enemy champions will also apply a stack of Plasma.

Innate - Caustic Wounds: Plasma stacks applied by Kai'Sa's basic attacks or Void Seeker deal 4 – 30 (based on level) (+ 12% AP) additional magic damage plus 1 – 8 (based on level) (+ 3% AP) additional magic damage per Plasma stack on the target before application, up to a total of 8 – 62 (based on level) (+ 24% AP) additional magic damage at 4 Plasma stacks before application. The fifth stack against a target consumes them all to deal additional magic damage equal to 15% (+ 6% per 100 AP) of the target's missing health, capped at 400 against monsters.

Notes (8)

Adaptive force from items does not count toward evolutions.
Kai'Sa may receive an evolution even if she dies during its lockout.
Kai'Sa can evolve an ability even if she hasn't learned it yet.
The bonus missing health damage is evaluated after the initial damage from Caustic Wounds is evaluated, and after Void Seeker's damage if triggered by it, but before a triggering basic attack's is.
This effectively increases the "flat" Caustic Wounds damage preceding the expunge proc and (if applicable) Void Seeker damage and any potential preceding on-hit damage (usually not possible to acquire due to buff slot order) by 15% (+ 6% per 100 AP) divided by (1+the target's MR post penetration/100).
Spell shield will block the Plasma application from Void Seeker only.
When applying Plasma with Void Seeker, Plasma stacks will roll over; in other words, the remaining stacks of Plasma after the detonation are reapplied on the target.
Additionally, Caustic Wounds' damage based on Plasma stacks on the target is calculated as if each stack were applied successively.

Tips & tricks (1)

Kai'Sa can avoid the cast time of evolving by initiating Recall or Supercharge immediately upon starting to evolve an ability.(bug)

Supercharge

Cost: 30 ManaCooldown: 16 / 14.5 / 13 / 11.5 / 10Cast time: 1.2 – 0.6 (based on bonus attack speed)Attack missile speed: 2500

Active: Kai'Sa charges up over the cast time, during which she is still able to move, becoming ghosted and gaining bonus movement speed for the duration, with the effectiveness increased by 0% – 100% (based on bonus attack speed).

Minimum Movement Speed: 55 / 60 / 65 / 70 / 75%
Maximum Movement Speed: 110 / 120 / 130 / 140 / 150%

After completing the charge, she gains bonus attack speed for 4 seconds, during which her attacks have a lower windup of 6.44% and an increased missile speed.

Bonus Attack Speed: 40 / 50 / 60 / 70 / 80%

Supercharge's current cooldown is reduced by 0.5 seconds on-attack.

Evolution: Requires「 100% – 70% (based on level) attack speed from items 」「 100% attack speed from items and stat growth 」to upgrade – Supercharge grants invisibility at the start of the cast time for 0.5 seconds.

Targeting input: AutoAffects: Self

Notes (2)

Her attack commands during this time are switched to movement commands instead. Upon finishing the charge and if an attack command was issued, Kai'Sa will continue walking toward her target.
Kai'Sa behaves normally if attack move click was issued not on a target during the cast time, stopping at attack range of the closest target and starts attacking when charged up.

Tips & tricks (2)

If Supercharge's cast time finished while its buff is still active, the movement speed buff lingers briefly longer.
This is only possible with a significantly high amount of ability haste and attack speed.

Killer Instinct

Cost: 100 ManaCooldown: 130 / 100 / 70Cast time: noneTarget range: 2000 / 2500 / 3000Effect radius: 525Speed: 3800

Active: Kai'Sa grants herself a shield for 2 seconds and dashes to a target location near a visible enemy champion that was affected by Plasma within the last 4 seconds. The shield's duration is refreshed when the dash ends.

Shield Strength: 100 / 150 / 200 (+ 90 / 135 / 180% AD) (+ 120% AP)

An enemy champion within range and affected by Plasma is required to cast this ability. Killer Instinct resets Kai'Sa's basic attack timer. Kai'Sa can cast any of her abilities during the dash.

Targeting input: LocationTarget out-of-range override: The ability will not castAffects: SelfGrounded: DisabledKnockdown: Interrupted

Notes (3)

Kai'Sa will issue a movement command to the targeted location regardless of whether the target location is valid. The dash is not buffered during this movement command. Kai'Sa will not dash if the targeted location becomes valid by walking in range or a nearby enemy champion becomes affected by Plasma.
If the targeted location is not valid, the range indicator will glow.
The enemy champion recently affected by Plasma must be in range of Kai'Sa for the targeted location to be valid, and not the targeted location itself.
