Best Kai'Sa Synergies

Use RiftMind to compare Kai'Sa synergies, weak synergy partners, duo win rates, synergy deltas, sample sizes, and role-specific partner picks for low and high Elo League of Legends team comps.

Updated 2026-09-20. Data is current for LoL patch 26.18 (all regions, low elo and high elo).

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 500 games.
