Read from Swain's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Swain | Kassadin is one of the weakest level-1 laners and you bully him off the wave. |
| Level 2 | Swain | At level 2 your Q plus autos out-damage his fragile early trading. |
| Level 3 | Swain | Level 3 your E Nevermove root punishes him every time his Q shield is down. |
| Levels 4-5 | Swain | Through levels 4-5 you deny the CS and XP his whole game depends on. |
| Level 6 | Swain | At 6 your Demonic Ascension outsustains his early Riftwalk poke and pins his blink-ins. |
| First item | Even / skill | First item you're still ahead and should be converting tempo into map pressure. |
| Two+ items | Kassadin | Two-plus items flip hard to Kassadin — his Riftwalk mobility and burst overwhelm your sustain. |
Levels 1-4 are heavily yours — Kassadin is one of the weakest early laners in the game and you're one of the better bully-mages once you have Q Death's Hand and E Nevermove. Shove the wave into him, and whenever his Q Null Sphere shield is down, walk up, land E, and chunk him with Q. Your goal is to deny him CS and XP so the scaling monster never gets to scale. Punish every last-hit under tower.
