How to win lane as Viktor against Cassiopeia · 55.63% win rate over 1,794 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Cassiopeia's Q sustain and Twin Fang out-trade you from level 1 despite even farming. |
| Level 2 | Even / skill | Level 2 is a skill-based CS phase before her kit fully comes online. |
| Level 3 | Even / skill | Level 3 stays a skill window as she begins ramping but you can still poke and dodge. |
| Levels 4-5 | Cassiopeia | By levels 4-5 her Q spam, movement speed, and Miasma grounding dominate every trade. |
| Level 6 | Cassiopeia | At 6 Petrifying Gaze plus Miasma is a near-guaranteed catch you can't kite. |
| First item | Cassiopeia | Her first-item mana and Twin Fang ramp melt you faster than you can answer. |
| Two+ items | Viktor | At two items your upgraded E and zone out-range her stand-still DPS and flip it. |
Cassiopeia is one of the worst scaling-mage lanes for you. Levels 1-2 are a skill-based farm phase, but the moment she has Q ranks and E her Noxious Blast sustain and Twin Fang resets out-trade anything you throw. You have almost no kill pressure into her, so focus on clean CS and don't get baited into extended exchanges.
