Track: Kai'Sa's E — Supercharge (16–10s cooldown). Her reposition + stealth window — engage in the sixteen seconds after she burns it.
Read from Smolder's seat: which stage windows this plan plays for against Kai'Sa.
This is Smolder's own plan; across 18,892 pooled games the lane is leaning Smolder.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Kai'Sa | Level 1 favours Kai'Sa because her Q trade and early plasma pressure beat your stack phase. |
| Level 2 | Kai'Sa | Level 2 stays Kai'Sa's as Void Seeker poke chips you while you lack burst. |
| Level 3 | Kai'Sa | Level 3 favours Kai'Sa since plasma stacking unlocks her ranged W execute threat. |
| Levels 4-5 | Kai'Sa | Levels 4-5 remain Kai'Sa's on the strength of her empowered E burst window. |
| Level 6 | Kai'Sa | Level 5 stays Kai'Sa's as her all-in potential outweighs your still-building damage. |
| First item | Smolder | At level 6 Killer Instinct gives Kai'Sa a dive all-in before your item spike lands... but once you complete first item and stack Q, it flips to Smolder. |
| Two+ items | Smolder | By 2+ items your uncapped flame Q and W execute out-range and punish her dive-reliant kit. |
Levels 1-2 lean Kai'Sa: her Q Icathian Rain trades hard and Void Seeker pokes you off the wave while you have no burst and are grinding Dragon Practice. Farm from behind minions to eat her W and never let plasma stacks build to the execute threshold. Two scaling carries in one lane means the loser is whoever blinks first on farm, so hold your ground and keep the count moving. Answer her step-ups with a sneeze rather than an auto trade. Her support is the only real threat, so save the dash for that and take the plate on the crash.
