Track: Kassadin's R — Riftwalk (5–2s cooldown). His mobility spike — the lane is decided before it scales.
Read from Diana's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Diana | Kassadin has almost no early kit, easy target for an all-in at level 1 |
| Level 2 | Diana | Diana's Q poke punishes his weak short-range Q trades cleanly |
| Level 3 | Diana | Diana's burst combo threatens a kill his mana pool can't answer |
| Levels 4-5 | Diana | Kassadin remains mana-starved and immobile through levels 4-5, still losing |
| Level 6 | Even / skill | Diana's Moonfall all-in is still ahead of his short, costly Riftwalk |
| First item | Even / skill | Diana's tempo lead from items lets her keep pressing before Kassadin scales |
| Two+ items | Kassadin | Kassadin's full build Riftwalk mobility and burst finally overtake Diana's kit |
Kassadin is one of the weakest level 1-5 mid laners in the game — mana-hungry, a 650-range Q, and no wave clear. All-in him with Q-mark into E whenever he steps up to farm. His only trade is Nether Blade, an auto-attack reset on a 7s cooldown: the wind-up is your cue to step out, not the cast. Deny his CS and this window is your whole matchup.
