Favour timeline — the windows in Cassiopeia's game plan

Read from Cassiopeia's seat: which stage windows this plan plays for against Nautilus.

StageFavouredWhy
Level 1Even / skillHe has a passive auto-root (Staggering Blow) but no kill setup at level 1, and you are just as weak early — last-hit at Q range and respect a possible hook.
Level 2CassiopeiaBy level 2-3 you can prime-and-Twin-Fang, and his only engage is a slow, dodgeable Dredge Line hook on a long cooldown.
Level 3CassiopeiaYour full Q-into-E poison combo plus Serpentine Grace move-speed kiting out-trades a tank who can only walk forward into your zone.
Levels 4-5CassiopeiaRanks in Q and E let you chain Twin Fangs that refund on every poison tick — an immobile Nautilus standing in your poison loses every extended trade.
Level 6CassiopeiaPetrifying Gaze answers his all-in: face and stun him as the hook lands, then chain Twin Fang before his tank stats matter.
First itemCassiopeiaLiandry's or Malignance plus your AP scaling shreds his low early MR with %-health burn — your hardest kill window.
Two+ itemsCassiopeiaA pure-tank Nautilus never passes you in single-target threat, so you keep out-DPSing him — just respect that his hook chain lets a jungler punish any overextend.

How to beat Nautilus as Cassiopeia: the early game

At Level 1 you both do little — his autos apply a Staggering Blow root but he can't lock you down without committing his Dredge Line hook (Q), so last-hit at the edge of your Noxious Blast range and respect a possible pull. Once you hit Level 2-3 the lane tilts your way: prime him with Q, then spam Twin Fang (E) on the poisoned target — it refunds most of its cooldown so you fire near-continuously, and his only initiation is a slow, telegraphed hook you dodge on your Serpentine Grace move speed. The one thing that kills you here is getting hooked when his jungler is missing, so keep the wave on your side and never walk into unwarded brush.
