Kai'Sa is a versatile marksman who excels as an autoattack-based teamfighter, assassin, or poke mage, making her a strong pick when played skillfully.

Passive - Second Skin Normal attacks deal bonus magic damage based on level and Caustic Wounds stacks. Attacks and abilities mark enemies with "Plasma" (up to 4 stacks), consuming stacks to deal 15% (+2.5% per 100 AP) max health magic damage.

Q - Icathian Volley

  • Releases 6 projectiles targeting nearby enemies
  • Double damage to low-health minions
  • Reduced damage to champions after first hit
  • Evolution (100 bonus AD): Doubles projectiles
  • Can be cast during other actions

W - Void Projectile

  • Long-range skillshot (3000 units)
  • Marks targets with 2 Plasma stacks
  • Evolution (100 bonus AP): Applies 3 stacks, 77% cooldown refund on champion hits
  • Can be repositioned during cast animation

E - Super Energy

  • Charges to gain movement and attack speed
  • Auto attacks reduce cooldown
  • Evolution (100% bonus attack speed): Brief invisibility
  • Can cast Q during charge

Ultimate - Killer Instinct

  • Dash to Plasma-marked champions (1500/2250/3000 range)
  • Grants shield scaling with AD/AP
  • Can use abilities mid-flight
  • Flexible positioning within attack range

Skill Order

  1. Q - Icathian Volley
  2. W - Void Projectile
  3. E - Super Energy Prioritize Q > E > W for AD/Attack Speed builds

Gameplay Tips

  • Coordinate with allies' CC for Plasma stacks
  • Use ultimate creatively for outplays
  • Track evolution thresholds for power spikes
  • Combine abilities during ultimate dash
  • Position carefully to maximize Q damage

Kai'Sa's build path focuses on achieving ability evolutions while adapting to the current meta. Prioritize items that grant AD for Q evolution, attack speed for E evolution, and AP for W evolution based on your preferred playstyle.
