How to win lane as Cassiopeia against Orianna · 47.3% win rate over 518 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Orianna | Orianna's Command: Attack ball poke and Dissonance zoning punishes your low base HP before you have a combo to answer with |
| Level 2 | Orianna | She continues controlling the wave and poking safely with her ball, keeping you on the back foot through this stretch |
| Level 3 | Even / skill | Trades even out here as your E range starts to threaten her ball positioning, but neither side has a clean window |
| Levels 4-5 | Cassiopeia | Your poison stacking and combo range begin outpacing her poke damage once you have full rotation timing |
| Level 6 | Cassiopeia | Petrifying Gaze now out-ranges her Shockwave setup, letting you punish overextensions decisively |
| First item | Cassiopeia | Item power widens your DPS lead as her ball-dependent damage falls off relative to your DoT scaling |
| Two+ items | Cassiopeia | Full-build Cassiopeia out-damages Orianna in any extended fight as long as you dodge Command: Shockwave |
Orianna's ball gives her constant poke and wave control that you can't easily answer at levels 1-2 — she can zone you off CS and chip your HP from a position you can't punish yet. This continues to favor her through level 3 as she freezes the wave and keeps landing ball pokes while staying safe. It's close to even by level 4-5 once your own combo range starts threatening her ball positioning, but she still holds a slight edge in raw poke damage through this stretch.
