Read from Karma's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karma | Karma's early poke still wins small trades before Cassiopeia's combo is online. |
| Level 2 | Karma | Karma's harass edge holds for one more level before her kit ramps up. |
| Level 3 | Even / skill | Both sides are close here as her poison combo starts coming online but isn't fully lethal yet, a genuine skill check. |
| Levels 4-5 | Cassiopeia | Cassiopeia's poison-stack combo begins outdamaging Karma's trades once fully set up. |
| Level 6 | Cassiopeia | Her stun-lock potential from Petrifying Gaze makes this a losing fight to force. |
| First item | Cassiopeia | Her completed burst item lets single combos overwhelm Karma's shields. |
| Two+ items | Cassiopeia | Cassiopeia's scaling poison and execute threshold outclass Karma's utility late. |
You have a real but short-lived edge at levels 1-2 — Cassiopeia's poke is clunky before she can reliably land Noxious Blast, so quick Q/E trades in and out win you small chunks of HP. This window closes fast though: by level 3 she starts layering poison zones with Twin Fang follow-ups and the trade math flips hard in her favor. Don't get greedy chasing trades past level 3 — take what you can early and transition to a more cautious poke-and-reset game as her kit comes online. Ward her approach angles since her range starts creeping past yours quickly.
