Read from Illaoi's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Illaoi | Illaoi dominates level 1 — Kassadin is helpless early and can't trade with you. |
| Level 2 | Illaoi | Level 2 stays yours as he can only farm passively under your tentacle pressure. |
| Level 3 | Illaoi | At level 3 W Harsh Lesson lets you punish every Q-shield cooldown for free. |
| Levels 4-5 | Illaoi | Levels 4-5 you keep walking him down before his spike arrives. |
| Level 6 | Illaoi | Level 6 still favors you — a landed E and R kill him before Riftwalk stacks save him. |
| First item | Illaoi | First item you retain the edge but his Rod of Ages spike is looming. |
| Two+ items | Kassadin | At 2+ items Kassadin outscales hard, Riftwalking out of tentacles and bursting you down. |
Levels 1-2 are all yours — Kassadin is one of the weakest early laners in the game, and with tentacles seeding the wave he can't contest CS without eating W Harsh Lesson trades.
