Abilities[]

Edit

Second Skin

Second Skin

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.

Kai'Sa Plasma

Innate - Plasma: Kai'Sa's basic attacks On-hit icon on-hit and Void Seeker 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 Void Seeker applies 2 stacks, increased to 3 if it is evolved evolved. Her and nearby allies' Stun icon immobilizing effects and Silence icon polymorphs against enemy Champion icon champions will also apply a stack of Plasma.

Innate - Caustic Wounds: Plasma stacks applied by Kai'Sa's basic attacks or Void Seeker Void Seeker deal 5 − 23 (based on level) (+ 1 − 12 (based on level) per Plasma stack before application) (+ 15% − 25% (based on Plasma stacks before application) AP) bonus magic damage. The fifth stack against a target consumes them all to deal additional bonus magic damage equal to 15% (+ 6% per 100 AP) of the target's missing health, capped at 400 against Monster icon monsters.

Info
  • Kai'Sa receives the evolution even if she dies while in cast time.
  • 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 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 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).
  • Plasma stacks that exceed the rupture are reapplied normally.
  • Spell Shield Spell shield will block the Plasma application from Void Seeker Void Seeker only.
  • With Void Seeker Void Seeker, if the stacks detonate Plasma, any remaining stacks are reapplied afterwards. Void Seeker Void Seeker also deals Caustic Wounds' damage based on Plasma stacks on the target. This damage is calculated as if each stack was applied successively.
    • Hitting a target with 0 stack with normal Void Seeker: 10 − 46 (based on level) (+ 1 − 12 (based on level) (+ 32.5% AP)
    • Hitting a target with 3 stacks with normal Void Seeker: 10 − 46 (based on level) (+ 7 − 84 (based on level) (+ 47.5% AP)
    • Hitting a target with 0 stack with evolved Void Seeker: 15 − 69 (based on level) (+ 3 − 36 (based on level) (+ 52.5% AP)
    • Hitting a target with 2 stacks with evolved Void Seeker: 15 − 69 (based on level) (+ 9 − 108 (based on level) (+ 67.5% AP)

Physical Damage Per Missile:
40 / 55 / 70 / 85 / 100 (+ 55% bonus AD) (+ 20% AP)

Non-minions take 25% damage from missiles beyond their first.

Reduced Damage Per Missile:
10 / 13.75 / 17.5 / 21.25 / 25 (+ 13.75% bonus AD) (+ 5% AP)
Total Single-Target Damage:
90 / 123.75 / 157.5 / 191.25 / 225 (+ 123.75% bonus AD) (+ 45% AP)
Icathian Rain 2

Evolution Evolution: Requires「 Attack damage icon 100 − 56 (based on level) attack damage from items 」「 Attack damage icon 100 attack damage from items and stat growth 」to upgrade – Icathian Rain instead fires 12 missiles.

Total Evolved Single-Target Damage:
150 / 206.25 / 262.5 / 318.75 / 375 (+ 206.25% bonus AD) (+ 75% AP)

A nearby enemy is required to cast this ability.

Info
  • The first missile on a target applies Death Lotus area damage, while the rest on the same target apply Poison Trail persistent area damage.
  • Spell Shield Spell shields only block the damage from a single missile.
  • Icathian Rain acquires its targets upon cast. Moving will not change its targets.
  • Charging Supercharge Supercharge will not stop the missiles from firing.

Edit

Void Seeker

Void Seeker

Active: Kai'Sa fires a void bolt in the target direction that briefly grants Sight icon sight around its trajectory as it travels, deals magic damage to the first enemy hit, applies 2 Plasma, and True Sight icon reveals them for 4 seconds.

Magic Damage:
30 / 55 / 80 / 105 / 130 (+ 130% AD) (+ 45% AP)
Void Seeker 2

Evolution Evolution: Requires Ability power icon 100 ability power from items to upgrade – Void Seeker applies 3 Plasma instead and refunds 75% of its Cooldown icon cooldown if it hits an enemy Champion icon champion.

Info
  • This ability will cast from wherever the caster is at the end of the cast time.

Edit

Supercharge

Supercharge

Active: Kai'Sa charges up over the cast time, during which she is still able to move, becoming Ghost ghosted and gaining Movement speed icon 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 Attack speed icon bonus attack speed and reduces her basic attack windup percentage by 6.44% for 4 seconds.

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

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

Supercharge 2

Evolution Evolution: Requires「 Attack speed icon 100% − 70% (based on level) attack speed from items 」「 Attack speed icon 100% attack speed from items and stat growth 」to upgrade – Supercharge grants Twilight Shroud old2 invisibility at the start of the cast time for 0.5 seconds.

Info
  • 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
  • If Supercharge's cast time finished while its buff is still active, the movement speed buff lingers briefly longer.

Edit

Killer Instinct

Killer Instinct

Active: Kai'Sa grants herself a Hybrid resistances icon shield for 2 seconds and Dash dashes to a target location near a Sight icon 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:
70 / 90 / 110 (+ 90 / 135 / 180% AD) (+ 120% AP)

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

Info
  • 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.
  • The basic attack reset is not considered one for Hail of Blades Hail of Blades.

Kai'Sa OriginalSkin
Original
RP 975
07.03.2018
Claimed by the Void when she was only a child, Kai’Sa managed to survive through sheer tenacity and strength of will. Her experiences have made her a deadly hunter and, to some, the harbinger of a future they would rather not live to see. Having entered into an uneasy symbiosis with a living Void carapace, the time will soon come when she must decide whether to forgive those mortals who would call her a monster, and defeat the coming darkness together… or simply to forget, as the Void consumes the world that left her behind.
