How to win lane as Samira against Kai'Sa · 53.57% win rate (18,654 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Her scaling needs a lane you intend to cancel — all-in the early windows and grade the curve out of the game.
Track: Kai'Sa's E — Supercharge (16–10s cooldown). Her reposition + stealth window — engage in the sixteen seconds after she burns it.
Read from Samira's seat: which stage windows this plan plays for against Kai'Sa.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Samira | You beat dashless Kai'Sa at level 1 since she can't escape your gap-close. |
| Level 2 | Samira | At level 2 she's still immobile and exposed while stacking her plasma passive. |
| Level 3 | Samira | Level 3 gives you the dash to punish her every time she steps up to trade. |
| Levels 4-5 | Samira | Through 4-5 you windwall her Q and force melee brawls she can't kite yet. |
| Level 6 | Samira | At 6 your ult executes her before her R dash-shield can reposition out. |
| First item | Samira | At first item you out-brawl her before her evolutions and core spike land. |
| Two+ items | Kai'Sa | Late, fully-evolved Kai'Sa out-mobilities and out-bursts you with R and evolved Q. |
You beat a dashless Kai'Sa at 1-2: she can't escape your Q gap-close, so every step she takes to stack plasma or farm exposes her to your all-in. Until Supercharge is levelled there is no exit in her kit, so every caster minion she reaches for is an invitation. Whirl blunts the missiles as you arrive. Do not eat a third plasma proc: finish the grade, leave, and take the plate rather than pushing into fog.
