Kai'Sa ADC duo tips

  1. Shen & Kai'Sa - Stand United(R) shields Kai'Sa and teleports Shen to her, while Shen's Shadow Dash(E) taunts enemies; allied immobilizing effects add Kai'Sa's Plasma stacks.
  2. Kai'Sa & Neeko - Neeko's Tangle-Barbs(E) and Pop Blossom(R) immobilize targets, adding Plasma stacks for Kai'Sa. If the target remains visible and within Kai'Sa's current rank's Killer Instinct(R) range, that crowd control gives her an opening to join Neeko's engage.
  3. FiddleSticks & Kai'Sa - Crowstorm(R) lets Fiddlesticks enter a fight from an unseen angle, where its damage can trigger Terrify(Q)'s fear across multiple enemies. That immobilization adds Kai'Sa's Plasma stacks and gives her a window to join a marked target with Killer Instinct(R).
  4. Kai'Sa & Galio - Galio's taunt and knockups are immobilizing effects that help apply Kai'Sa's Plasma; Hero's Entrance(R) also shields an ally and knocks up enemies where Galio lands.
  5. Kai'Sa & Amumu - Amumu's Bandage Toss(Q) and Curse of the Sad Mummy(R) stun enemies, helping stack Kai'Sa's Plasma; Cursed Touch(P) also makes targets take bonus true damage from incoming magic damage.

How these matchup statistics are calculated

Counter and synergy statistics use Ranked Solo/Duo games, exclude matches shorter than 600 seconds, and group results by patch window, region, rank scope, and champion role.

Pairwise pages use a rolling three-patch window and compare observed win rate with a log-odds expected win rate based on each champion's role-adjusted baseline; listed pairs require at least 1,000 games.
