Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillYou have only Q and must walk to melee range; Cassiopeia's Noxious Blast (Q) poison activates Twin Fang spam before you can threaten a root.
Level 2CassiopeiaHer Q poison into Twin Fang loop is fully online and she has the move-speed buff from Noxious Blast to stay outside your W root range.
Level 3CassiopeiaYour E-Q-W loop completes but her Miasma (W) grounds you the moment you step up, collapsing your combo window if it lands before your root.
Levels 4-5CassiopeiaHer Twin Fang costs zero mana on a poisoned target and your mana bar bleeds pre-Seraph's — she outpaces you on sustained DPS through this entire phase.
Level 6CassiopeiaRealm Warp is her free deny tool: she drops Miasma on your feet during the channel animation and your warp is cancelled, neutralising your biggest level-6 threat.
First itemCassiopeiaRylai's slow plus poison uptime means she kites your root indefinitely; her Malignance spike also reduces your window to safely step into Flux range.
Two+ itemsRyzeSeraph's loop speed finally threatens isolated targets — E-W-Q chains kill a grounded Cassiopeia before Twin Fang refunds can save her, and your warp repositions the fight onto her.

Early game (levels 1–5)

At level 1 you only have Q, which means walking into melee range to trade — Cassiopeia punishes this instantly with Noxious Blast (Q) poison into Twin Fang spam that refunds its own cooldown. Do not fight. Last-hit with Q at its max range and accept that she controls the wave. At level 2 your W root gives you one real threat: if she overextends to push, root her before she can drop Miasma and squeeze off empowered Q. Level 3 completes your E-Q-W loop, but she completes hers too — the key is that your W root must land BEFORE her W Miasma hits the ground, or you are grounded and your entire damage window collapses. Bait her into stepping onto your E Flux mark by feinting forward, then immediately chain W-Q.
