Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillYou're both weak level 1 — she has no real Twin Fang chain yet and you have no Hallowed Mist, so it's a wash decided by who wins the last-hit poke; just deny her free Q (Noxious Blast) harass on the wave.
Level 2CassiopeiaHer Q poison plus Twin Fang out-chip you while you have no W untargetability and no E range to answer — eat the poke and farm rather than walking into the cloud.
Level 3CassiopeiaShe still out-stats you here: Miasma grounds any raw Skip 'n Slash you try, and her poison keeps Twin Fang's bonus damage online faster than you can trade back.
Levels 4-5GwenOnce you hit your full kit you out-trade a no-mobility mage — drop Hallowed Mist on her engage so the poison whiffs, then E-dash in after the grounding ends.
Level 6CassiopeiaHer R (Petrifying Gaze) is a hard answer at 6: if it lands frontally she stuns you out of W and full-combos before you can mist the damage or dash away.
First itemGwenNeedlework plus your full Q-W-E lets you mist her R, slow her with R, and grind her squishy bar down — your real flip point this lane.
Two+ itemsGwenYour Riftmaker/Nashor's spike plus %-max-HP Snip Snip! and Hallowed Mist untargetability win every extended duel — all-in before her 2-item kite scaling arrives.

Early game (levels 1–5)

Levels 1-3 are hers, not yours. Cassiopeia's Q (Noxious Blast) poison and Twin Fang chip you down before you have Hallowed Mist to hide in or Skip 'n Slash's on-hit range to touch her, and her W (Miasma) grounds your dash if you try to force it raw. Don't walk up to last-hit into her poison cloud — soak the minimum, eat the chip, and stay above half HP so her R never has a kill setup. You have no untargetability yet, so this is a farm-and-survive window; respect that Twin Fang deals bonus damage and refunds on a poisoned target, so every tick she lands speeds up her next one.
