How to win lane as Kassadin against Vex · 51.21% win rate over 701 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Vex | Vex's ranged poke and passive punish your melee approach before you have mobility, so early favors her. |
| Level 2 | Vex | Continued Doom Gaze stacking and safe poke damage extend her lead as the laning phase progresses. |
| Level 3 | Vex | She's still ahead on chip damage and fear pressure heading toward level 6. |
| Levels 4-5 | Vex | Her Shadow Surge dash-burst combo is the more threatening all-in the moment both ultimates unlock, so this spike favors her. |
| Level 6 | Kassadin | Once you have Riftwalk stacks you can finally close distance and punish her lack of true peel, tipping this phase to you. |
| First item | Kassadin | Item power plus Riftwalk mobility let you close the range gap she depends on, favoring you. |
| Two+ items | Kassadin | Full build your mobility advantage over her non-kiting dash is decisive, so late favors you. |
Vex's ranged Mistral Bolt poke and Personal Space passive punish your melee-only kit hard before level 6, and every stack of Doom Gaze threatens a fear-execute if she gets you low, so you're forced to play very passively and concede early CS pressure.
