How to win lane as Kassadin against Yasuo · 54.6% win rate over 2,511 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Yasuo | Yasuo's Wind Wall directly counters your main engage tool from level 1, so early clearly favors him. |
| Level 2 | Yasuo | His shield passive keeps letting him tank trades for free as the lane continues. |
| Level 3 | Yasuo | Continued wall-and-shield trading pattern keeps him ahead heading into level 6. |
| Levels 4-5 | Yasuo | His knock-up all-in combo is the scarier kill threat the moment both ultimates unlock, favoring him. |
| Level 6 | Yasuo | Wind Wall still blocks your core engage tool at this exact power spike, keeping the phase in his favor. |
| First item | Yasuo | Wind Wall continues to threaten your Riftwalk-Q engage even as you gain item power, so this phase still favors him. |
| Two+ items | Kassadin | Once you can bait Wind Wall and engage from an angle it can't cover, your burst finally outpaces his shield-tanked damage, favoring you late. |
Yasuo's Wind Wall completely negates your primary poke tool, and his movement-based shield passive lets him no-cost tank the trades you do land, so you're stuck in a lane where your core kit is actively countered before you even reach level 6.
