Read from Vex's seat: which stage windows this plan plays for against Kassadin.
This is Vex's own plan; across 1,490 pooled games the lane is leaning Vex.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 Kassadin is helpless and you can shove and poke him freely. |
| Level 2 | Even / skill | Level 2 your W lets you punish any step-up while he can't retaliate. |
| Level 3 | Even / skill | Level 3 your W+Q all-in threatens a kill on a laner with no escape. |
| Levels 4-5 | Even / skill | Through levels 4-5 you keep denying CS and delaying his Riftwalk spike. |
| Level 6 | Even / skill | At 6 your Doom passive still fears his Riftwalk before he can chain blinks. |
| First item | Even / skill | First item you stay ahead and R answers his early Riftwalk engages. |
| Two+ items | Kassadin | With two items his stacked Riftwalks blink past your fear and out-scale you. |
Levels 1-5 are all yours. Kassadin is one of the weakest laners in the game before 6, so shove the wave into him, deny CS, and all-in with W+Q whenever he steps up for a caster minion. He has no way to fight back and his only defense is the Null Sphere shield and backing off. Every point of farm you deny pushes his Riftwalk spike later.
