Read from Vex's seat: which stage windows this plan plays for against Diana.
This is Vex's own plan; across 3,121 pooled games the lane is leaning Vex.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | You out-range Diana at level 1 and your passive already threatens any early dash-in. |
| Level 2 | Even / skill | At 2 your empowered Q punishes her short Crescent Strike walk-ups before she can gap-close safely. |
| Level 3 | Even / skill | By 3 any Lunar Rush onto you procs Doom, letting you fear-interrupt her whole combo. |
| Levels 4-5 | Even / skill | Levels 4-5 you keep answering every dash with a fear and W burst, denying her all-ins. |
| Level 6 | Even / skill | At 6 her Lunar Rush spike is exactly the dash your passive punishes, so you win the ult trade. |
| First item | Even / skill | Her first-item burst is neutralised by fear-cancelling the combo or W-shielding it. |
| Two+ items | Even / skill | Late, holding R and W to fear her flank engage turns every dive, keeping the counter intact. |
You out-poke Diana at range early since she must farm with Q and shield up, and any time she tries to walk you down you punish with empowered Q; more importantly, your passive is built to answer her exact game plan of dashing in. Track Diana Crescent Strike (Q): 8s at rank 1 — Moonlight resets her Lunar Rush, so sidestep the arc and her dive has no follow-up.
