| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Level 1 favours Cassiopeia -- her poke chips you with no gap-close to answer. |
| Level 2 | Cassiopeia | Level 2 stays hers as her ramping E out-trades you at range. |
| Level 3 | Sett | Level 3 is your window: E-stun into W when her Miasma is on cooldown. |
| Levels 4-5 | Cassiopeia | Level 4 she reclaims control with the Miasma slow zone. |
| Level 6 | Cassiopeia | At 5 her E ramp and W slow keep you poked out. |
| First item | Cassiopeia | At 6 R Petrifying Gaze stuns your all-in and she kills you through it. |
| Two+ items | Cassiopeia | By 2+ items the Miasma slow, R stun, and Twin Fang beat your engage. |
Levels 1-2 Cassiopeia pokes you out -- her Q and ramping E chip you while you have no gap-close yet. Soak with P Pit Grit and don't walk into her W slow before you have E.

Sett takes Conqueror on the Precision tree with Triumph, Legend: Alacrity and Last Stand, and Resolve secondary (Second Wind and Bone Plating) vs Cassiopeia.
Start Doran's Shield + Health Potion (vs her poke) and back for Phage / Tiamat + boots (≈1300g). Build Stridebreaker (stick to them through the W panel window) first, then Sterak's Gage (Maw if her magic burst is the problem), with Mercury's Treads.
