How to win lane as Kassadin against Master Yi · 46.91% win rate over 194 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Kassadin | Your Null Sphere silence edges the level-1 trade — it shuts down his answer. |
| Level 2 | Even / skill | By 2 it evens out as your weak pre-6 kit starts to show. |
| Level 3 | Master Yi | His Wuju true damage crushes your level-3 lane. |
| Levels 4-5 | Master Yi | At 4-5 he out-DPSes you hard — Riftwalk has not arrived to save you yet. |
| Level 6 | Master Yi | Even at 6, your early Riftwalk cannot out-trade his R steroids. |
| First item | Master Yi | His first-item spike lands well before your AP scaling does. |
| Two+ items | Kassadin | Late, stacked Riftwalk lets you kite his Highlander and finally win the duel. |
Take the level-1 trade — Null Sphere's silence beats his opener — then swallow your pride, because from 3 onward his Wuju true damage crushes your fragile pre-6 frame. Farm at max range, ward early, and treat every extended trade from 3 to 5 as a mistake you volunteered for.
