Track: Zeri's E — Spark Surge (24–18s cooldown). The wall-dash escape — she is catchable only while it is down.
Read from Kai'Sa's seat: which stage windows this plan plays for against Zeri.
This is Kai'Sa's own plan; across 15,485 pooled games the lane is leaning Zeri.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is skill-even as neither champ has a trade tool and it's pure last-hitting. |
| Level 2 | Zeri | Level 2 favors Zeri because her spammable Burst Fire poke chips you while you set up. |
| Level 3 | Kai'Sa | Level 3 is yours since your W-mark combo out-ranges her short Burst Fire on every walk-up. |
| Levels 4-5 | Even / skill | Levels 4-5 are even: you out-range her but her Ultrashock slow and wall-dash trade it back. |
| Level 6 | Even / skill | Level 6 is a skill coin-flip because her Lightning Crash reset can snowball a won fight either way. |
| First item | Even / skill | First item stays even as your %HP shred matches her scaling but her kite resists your pin. |
| Two+ items | Even / skill | 2+ items remain skill-based since her wall-dash and shield out-kite unless you burst her first. |
Level 2 tilts slightly to Zeri because her Burst Fire is a steady spammable poke that chips you while you set up W stacks, so respect the early trade and farm safely. She has no hard commit yet, so a poke support keeps it manageable. Her chip is constant but small, so farm through it and let the missiles do the clearing. Do not spend mana trying to answer poke you can simply walk out of. Your first component is where this lane turns, so take the safe CS, bank plasma on the wave, and play for the plate.
