How to win lane as Kassadin against Yasuo · 53.85% win rate over 52 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Yasuo | Yasuo is the level-1 aggressor: Steel Tempest out-ranges your Null Sphere and his Windwall can fully block your only poke spell. |
| Level 2 | Yasuo | His Q poke plus E dash-through-minions let him chip you freely while your shallow early mana pool can't sustain a Null Sphere trade-war. |
| Level 3 | Even / skill | Around 4-5 it evens out: Nether Blade mana and a maxed Null Sphere let you farm through his poke and reach 6 without dying to one combo. |
| Levels 4-5 | Kassadin | Riftwalk lets you blink out of his E into third-Q knockup before Last Breath connects, or blink in to punish his E cooldown. |
| Level 6 | Kassadin | Rod of Ages stall plus Riftwalk ability haste lets you blink-trade on his Steel Tempest downtime and stop bleeding pressure to him. |
| First item | Kassadin | Your post-6 mobility and shield turn the lane: you control engage timing on his cooldowns where he controlled the early poke. |
| Two+ items | Yasuo | Once Yasuo hits two crit items, his Infinity Edge DPS, flow shield, and Windwall outscale you in any extended duel, so that window is his. |
Neither of you blows the other up at level 1, but Yasuo is the early aggressor here. His Steel Tempest (Q) out-ranges your Null Sphere, and once he can E through the wave he chips you while your Q is mana-hungry and on a long cooldown, so don't trade orbs you can't afford. His Windwall (W) eats your Null Sphere outright, so never throw it into a raised W; wait it out. Farm with Nether Blade autos to bank mana, concede the poke, and just reach 6 healthy.
