Kai'Sa is a champion in League of Legends.


  • Biography
  • Story
Perhaps the most remarkable thing about the fearless hunter of the Void known as Kai’Sa is how unremarkably her life began. She did not descend from tribal warriors hardened by generations of battle, nor was she summoned from distant lands to fight the unknowable menace lurking beneath Shurima. Rather, she was just an ordinary girl, born to loving parents who called the unforgiving southern deserts their home. This was where she would spend her days playing with friends, and her nights dreaming about her place in the world.

In her tenth summer, the young girl Kaisa’s destiny would be changed forever. Had she been older, she might have noticed more of the unusual events that had begun to unfold in the villages—every day, her mother urged her stay home, for fear of strangers wandering the land, demanding tribute to dark powers below. Kaisa and her friends did not believe it, until one evening they came upon a pen of sacrificial goats bought from nomad herdsmen. Using the knife her father had given her on her eighth birthday, she cut their tethers and set the animals free into a nearby canyon. It seemed like a harmless prank, until the unthinkable happened. The ground began to quake, flashes of light scorched the sky, and the children ran for their lives.

The Void had been awakened. A great rift split the bedrock, swallowing up Kaisa’s village and everyone in it, leaving nothing behind but sand pierced with twisted columns as black as night.

Kaisa regained consciousness to find herself trapped underground. She was filled with crippling fear, but there was still hope; she could hear the faint cries of other survivors. They called out to each other feebly, repeating their names one by one like a mantra. Sadly, by the third day, hers was the only voice left. Her friends and family were all gone. She was alone in the darkness.

It was only when all seemed lost that she saw the light.

She followed it down.

Along the way, she found meager sustenance. Amid the debris left by the collapse were ragged waterskins, rotting peaches—anything to keep starvation at bay. But, eventually, Kaisa’s hunger was replaced by fear once again. She found herself in a vast cavern, illuminated by an otherworldly purplish glow, and she could see she was no longer alone.

Skittering creatures swarmed in the depths. The first that came for Kaisa was no bigger than her, and she clutched her knife in both hands, ready to defend herself. The voidling horror knocked her to the ground, but she drove the blade into its pulsing heart, and the two of them tumbled deeper into the abyss.

The creature was seemingly dead, but its unnatural skin had taken hold upon the flesh of her arm. The dark shell tingled, but was hard as steel to the touch. In a panic, Kaisa broke her knife trying to remove it. But when the larger beasts came, she used it as a shield to make her escape.

Soon enough, she realized the shell was becoming part of her. As her daily struggle to survive drew out into years, this second skin grew with her, and so too did her resolve.

Now she had more than hope, she had a plan. Fight hard. Stay alive. Find a way back.

She was transformed, from frightened girl to fearless survivor, from prey to predator. For almost a decade, she has lived between two worlds in an attempt to keep them apart—the Void hungers to consume not only the scattered villages of Shurima, but the whole of Runeterra. She will not allow that to happen.

Though she has slain countless Void-constructs, she understands that many of the people she protects would see her as a monster herself. Indeed, her name has begun to pass into legend, an echo of the ancient horrors of doomed Icathia.

No longer Kaisa… but Kai’Sa.

"My appearance may frighten you, but make no mistake—I am on your side, and we fight to the bitter end."

“Listen to me,” I tell the little girl who found me here, beside the pit. “I need you to hear me. There isn’t much time.”

She leans forward, without a hint of fear in her eyes. “Tell me what to do.”

I like her. A slight smile breaks across my face, for the first time in what seems like… forever. “Not this,” I say, gesturing to the arrow gripped in her hand. She holds it like a spear.

I was only a child when the Void took me from my family, so I didn’t know any better either. But the rest of them, they were so careless. Sacrifices, offerings, tributes—whatever you want to call them, they were never going to work. It isn’t some god, appeased by gifts and prayers. It just wants to devour everything.

“You want to kill it? You want to destroy it?” I ask her.

She nods.

“Then starve it.”

The sensation of needles on my flesh grows stronger, as if in response to these words. The threatening presence is closing in around us, and my second skin constricts, pulling taut as a bow. I take one last deep breath before they come.

The sand begins to shift, puckering and falling away, like in an hourglass. Eerie pulses of light filter into the sky, as the construct-creatures heave themselves up into the Shuriman night, screeching and drooling. I steady myself, charging the energy inside my shoulder pods.

I grit my teeth, and release it.

Bright blooms of heat and pain find their targets quickly, raining down, stopping the creatures in their tracks, flinging them aside. The air is filled with an acid reek, and the hiss of melting chitin.

Soon there is nothing left of them. I wait for the needles’ itch to stop, but it doesn’t.

The girl is crouched beside me, ready. She probably cannot understand what she is seeing.

“Does it hurt?” she whispers, her hand reaching out for the glowing scales on my arm.

I pull back reflexively. She doesn’t even flinch.

“Sometimes,” I confess.

Not too far away, her village sleeps on unaware, for the most part. Curiosity had no doubt gotten the better of this little girl. So many stories, fables both frightening and fantastical. The voidling beasts hunting in the dead of night, calling to one another.

She just wanted to see for herself. See what lurks beyond the rocks, see the thing her people both fear and adore at the same time.

My skin tightens again. The needles, the constant itch…

I blink. “I’m sorry, you didn’t tell me your name.”

She stands up proudly, still brandishing the arrow. “I’m Illi. I came to protect my family from the monster.” She is no more than ten years of age.

“Well, Illi—sometimes running is the best thing to do.”

“But you don’t run,” she says, narrowing her eyes, “do you?”

A clever one, this girl. I shake my head. “Not anymore.”

“Then I won’t either!” Illi proclaims. Brave as well.

She has no idea what they’re dealing with. None of them do. All these things her people have done to rid themselves of the creatures, they were just ringing the dinner bell.

“You need to tell them, Illi. You need to make them understand. No more dancing beneath the new moon. And no more animals tied to stakes. The Void has no mercy to offer—it feeds or it dies.”

The day I came to understand this, was when I knew I had a chance. Maybe that’s why I survive, while so many others perish.

But survival always has its price. Ever since I found my way back, I’ve been paying it.

“Look…” the girl whispers. “They are coming to find us.”

I don’t have to look. I knew they would come. By instinct, the carapace draws over my face. Illi stares up at me.

“Don’t be frightened,” I say to her in a voice now so twisted and monstrous, it could have the opposite meaning.

“Of what?” she asks. I find myself wearing a smile she cannot see.

There are only a handful of people who’ve ever seen me in the flesh, or whatever it is that now covers my body. All but two of them are dead.

Illi’s people appear to be capable hunters. Only the capable live out here. I can see where she got her bravery. Their torches twinkle in the night.

“Papa!” she calls out to the searching villagers, without warning me. “I found her! The girl who came back!”

They’re heading toward us now, weapons at the ready, fire in their eyes. “Illi!” her father yells, nocking an arrow to his bow. “Get away from that... thing!

She looks up at me again, confused. For every little girl like Illi, there are ten others who would run the other way. Or worse. I know what most people say about me. I’ve seen their fear scrawled across mud walls, scratched into the canyon rocks.

Beware the girl who came back a monster.

They don’t know a thing about me. To them, I’m just something they do not want to face—a living, walking, fighting embodiment of what they fear most. I guess that’s why they added the mark to my name.

Ten years ago, I was only Kaisa—very much like Illi, hopeful about a future as limitless as the stars in the night sky. That future died the day the Void dragged me down.

The needles are back. Illi releases my hand just as my luminous weapons materialize over my arms. “Go to him,” I tell her. “Go to your father.”

“Illi, run!” her father pleads. He draws back his bowstring with trembling hands.

“No!” she yells, turning to me. “I don’t run anymore.”

I usher her forwards, keeping my eyes trained on the villagers. “No, Illi, you were born a fighter. They will need you.”

After a few steps, she turns back. “What do I tell them?”

“Tell them... Tell them to be ready.”

The Void has taken so much from me, but I refuse to let it take everything. These moments, where kindness and humanity shine through, where innocence and trust extinguish fear—they fill me with hope that we can defeat the rivers of timeless poison that flow beneath the world.

The first time I escaped the abyss, I did it for myself.

Maybe one day, it will be for them.

Patch History[edit]

Patch 9.18

E bonus attack speed decreased later.

We're reducing Kai'Sa's consistent damage so she'll be more inclined to assassinate prime targets as opposed to mowing down the enemy charge one at a time.

Supercharge.png E - Supercharge

BONUS ATTACK SPEED : [40/50/60/70/80%]

Patch 9.4
Removed Stormrazor from recommended items.

We changed Stormrazor. Stop building it first on Kai'Sa.

WE RECOMMEND... : Stormrazor removed in favor of Infinity Edge and Runaan's Hurricane

Passive proc scaling decreased. Ultimate shield duration decreased.

Shrinking AP Kai'Sa's tank shredding sharpens the tradeoffs she makes for investing in more AP than she needs to evolve W, while shortening Killer Instinct's shield duration means enemies can unload their burst damage a little sooner after the Daughter of the Void dives into range.

Second Skin.png Passive - Second Skin

PROC DAMAGE : 15% [(+3.75% per 100 AP)]
(+2.5% per 100 AP) target's missing health

Killer Instinct.png R - Killer Instinct

SHIELD DURATION : [3] 2 seconds

Passive damage decreased at later levels.

Reducing Kai'Sa's tank-busting prowess at later phases of the game.

Second Skin.png Passive - Caustic Wounds

PROC DAMAGE : [15-20% (at levels 1-18)]
15% (at all levels) target's missing health


Kai'Sa was one of the strongest marksmen prior to 8.11 and since her Rageblade build avoids this patch's early game power-downs to crit buits, that "front of the back" status has become stand-out dominance. (These changes include a W ratio boots to keep the AP Kai'Sa dream alive).

Second Skin.png Passive - Second Skin

Plasma base on-hit damage : [7-12] 4-10
plasma per-stack damage : [1-9] 1-5
plasma ap ratio : [0.2/0.25/0.3/0.35/0.4] 0.1/0.125/0.15/0.175/0.2

Void Seeker.png W - Void Seeker

AP Ratio : [0.45] 0.6 ap

ARMOR : [33.04] 28
HEALTH : [554.4] 571
HEALTH REGEN : [1.1] 0.7

Evolved Q missile count decreased. Missile damage is now flagged as area of effect. E duration decreased.

Dialing back Kai'Sa's late game scaling a bit so she doesn't carry quite so hard. Specifically, the interaction of her abilities with certain items—primarily healing from spell damage—ramps her into territory which can get excessive.

Icathian Rain.png Q - Icathian Rain

EVOLVED Q : [12] 10 missiles
BOMBARDMENT : Missile damage is now flagged as AoE in all cases.

Supercharge.png E - Supercharge

DURATION : [5] 4 seconds
TOO MUCH : Runaan's Hurricane bolts no longer grant Supercharge's cooldown reduction

Health regen and health regen growth decreased. Q damage ratio decreased.

In her early patches, Kai'Sa was struggling to get through the laning phase, so we boosted her laning phase with some buffs. As players continue to learn how to play her, we're stripping that strength away.

Base stats


Icathian Rain.png Q - Icathian Rain

DAMAGE RATIO : [0.4] 0.35 bonus attack damage
6 MISSILE DAMAGE RATIO : [1.0] 0.875 bonus attack damage
12 MISSILE DAMAGE RATIO : [1.72] 1.505 bonus attack damage

Attack range increased. Passive and Q ability power ratios increased. Q range increased. W ability power ratio decreased. E cast time decreased. E movement speed increased. R radius increased.

Kai'Sa's a new champion, and that means that players are still learning how she works—and in a lot of ways, so are we. One thing that really stands out is that? she does pretty well in the games where she gets ahead, but currently she's struggling pretty hard to ever get leads in the first place. The main culprit is her laning phase, where her low range makes it hard for her to get the good trades she needs, so we're starting by minorly buffing her range. We're also buffing the mobility her E gives, both by increasing the movement speed and decreasing the cast time, which should allow her a bit more positional freedom to choose when and where she fights. Her ability power ratios are also way too low to fulfill her flexible itemization fantasy, and with the Guinsoo's Rageblade changes below, we have some room to make those ratios a lot stronger.

Base stats

ATTACK RANGE : [500] 525

Second Skin.png Passive - Second Skin

STACK RATIO : [0.1/0.15/0.2/0.25/0.3]
0.2/0.25/0.3/0.35/0.4 ability power (on applying 1st/2nd/3rd/4th/5th Plasma stack)
PLASMA DETONATION RATIO : [2.5% ] 3.75% target's missing health per 100 ability power

Icathian Rain.png Q - Icathian Rain

RANGE : [575] 600
RATIO PER MISSILE : [0.2] 0.4 ability power
AP RATIO FOR 6 MISSILES : [0.5] 1.0 ability power

Void Seeker.png W - Void Seeker

RATIO : [0.65] 0.45 ability power
NOT A NERF : Void Seeker deals the same amount of damage due to Second Skin's buffs above. Evolved Void Seeker deals more damage than before.

Supercharge.png E - Supercharge

CAST TIME : [1.5-0.75]
1.2-0.6 seconds (at 0-100% bonus attack speed from items and levels)
MAXIMUM BONUS MOVEMENT SPEED : [80/90/100/110/120%]

Killer Instinct.png R - Killer Instinct

THINKING AHEAD Killer Instinct's shield is now granted on-cast. Still lingers for 3 seconds after dash ends.

Base attack damage increased. Q cooldown and mana cost decreased.

New champions always take some time for players to pick up. However, Kai'Sa is currently leaving the laning phase too far behind, which isn't giving players the opportunity to learn where she shines and how to play around that. For now, we're buffing up her early laning phase and cooldowns to give players better opportunities to master her kit.

COOLDOWN : [10/9/8/7/6]
