How to win lane as Kassadin against Illaoi · 46.15% win rate over 13 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Illaoi | Your weakest level in the game — only Null Sphere, no escape, and her tentacle plus first auto out-trade you flat. |
| Level 2 | Illaoi | She's planting tentacles while you're still farming — one Test of Spirit here chunks you with no Riftwalk to escape. |
| Level 3 | Illaoi | Full early kit and still underpowered; Force Pulse only refunds cooldown off nearby casts, so a passive lane starves your waveclear while she free-plants tentacles. |
| Levels 4-5 | Illaoi | The survival grind — Null Sphere the wave from range and dodge Test of Spirit purely so it doesn't kill you before 6. |
| Level 6 | Illaoi | Riftwalk is online and you can finally blink the spirit-pull, but she still out-sustains and out-trades you on her field — dodge, don't duel. |
| First item | Illaoi | Rod of Ages stalls you toward even, yet a single Test of Spirit into her tentacle field still flips any trade her way. |
| Two+ items | Kassadin | The monster wakes: stacked Riftwalk plus Nashor's/Rabadon's let you blink-burst an immobile Illaoi who can't chase you off her field. |
Pre-6 this is one of your worst lanes — you have no escape, little damage, and every tentacle she plants near you turns a trade into a beating. Last-hit from the very tip of Null Sphere, keep the Q shield to eat the burst when she throws Test of Spirit, and never walk into her tentacle field to contest a wave. If she lands the spirit-pull, you have to physically run from your own torn-off spirit or her tentacles slap you for half your bar — so treat that range like a death zone and concede the CS you can't safely take. Lean on Nether Blade to keep mana up, because once your pool is empty you have nothing but autos.
