Track: Sivir's E — Spell Shield (24–18s cooldown). Eats your key spell and refunds her mana — bait it with a cheap cast first.
Read from Kai'Sa's seat: which stage windows this plan plays for against Sivir.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sivir | Sivir's level 1 Boomerang and W push and out-poke your weak early Kai'Sa. |
| Level 2 | Sivir | At level 2 Sivir's W bounce plus Q keeps the poke and wave lead against you. |
| Level 3 | Sivir | Level 3 still favors Sivir as Spell Shield blanks your Q and her Q out-trades. |
| Levels 4-5 | Even / skill | Levels 4-5 even out as your Q max lets you contest short trades on her cooldowns. |
| Level 6 | Even / skill | Level 6 is a skill fight since her R kite counters your dash while your E threatens re-engage. |
| First item | Kai'Sa | Your first item and Plasma stacks let you out-DPS Sivir's raw AD. |
| Two+ items | Kai'Sa | With 2+ items your dash resets and burst delete Sivir before her team speed-buff matters. |
Sivir owns levels 1-3: her Boomerang (Q) plus W bounce out-trades and out-pushes you, and her Spell Shield (E) blanks your Q poke, so respect the wave and last-hit safely rather than walk into her double-poke. She out-pushes you before items, so take the safe CS and let her have the shove rather than spending mana on a race you lose. Her shield eats a missile, which makes throwing one into it a cheap way to open. Play for the crash, the plate and the first component rather than for a trade.
