Read from Katarina's seat: which stage windows this plan plays for against Kassadin.
This is Katarina's own plan; across 5,409 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 auto-Q harass bullies a melee mage with no escape and no meaningful trade-back. |
| Level 2 | Even / skill | Level 2 Q-E burst trades win through his Null Sphere shield while he has zero mobility to answer. |
| Level 3 | Even / skill | Full dagger rotations at 3 chunk him every time his Q is down, and he can't disengage. |
| Levels 4-5 | Katarina | You-favoured: levels 4-5 are your hardest deny window — he bleeds HP or CS every wave before Riftwalk exists. |
| Level 6 | Katarina | You-favoured: at 6 Death Lotus still wins committed fights and your shove-roam tempo beats his escape-only ultimate. |
| First item | Katarina | You-favoured: your first-item burst spike lands before Rod of Ages, keeping the kill window open. |
| Two+ items | Katarina | You-favoured: at 2+ items your teamfight resets edge his single-target burst — but only barely, so end before level 16 stacks flip it. |
Levels 1-2 are free pressure: Kassadin is a melee mage with no mobility and his passive magic-damage reduction barely dents your mixed dagger damage. Walk him off the wave with auto-Q harass, and take the level 2 Q-E trade aggressively — his only answer is the Q Null Sphere shield and a W Nether Blade auto that requires him to stand in your daggers. Deny CS relentlessly; every missed minion pushes his Rod of Ages spike further out. Just don't tunnel so hard you eat a gank while diving his tower.
