Info
Notes
  • 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.
    • This is only possible with high enough cooldown reduction and attack speed.

Killer Instinct Bladework.png resets Kai'Sa's basic attack timer.

Info
Notes
  • 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.
