Track: Irelia's E — Flawless Duet (16–10s cooldown). Her stun setup — dodge it and the dive falls apart.
Read from Kassadin's seat: which stage windows this plan plays for against Irelia.
This is Kassadin's own plan; across 2,302 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Irelia | Bladesurge resets on minions let her harass you freely, and one Null Sphere shield covers one hit of a reset chain |
| Level 2 | Irelia | Stack snowball continues and you still can't trade back meaningfully |
| Level 3 | Irelia | Level 3 barely helps — she's already ahead on stacks and all-in potential |
| Levels 4-5 | Irelia | Levels 4-5 stay hers — Flawless Duet's stun into Bladesurge resets is a full combo, and you have no blink yet to leave it |
| Level 6 | Even / skill | Riftwalk at 6 blinks out of Vanguard's Edge's wall before the slow lands, and one blink breaks every Bladesurge reset chain — level 6 tips to you |
| First item | Even / skill | Q interrupts her Defiant Dance charge and Riftwalk leaves the stun's follow-up |
| Two+ items | Kassadin | Mobility and MR from two items let you dictate fights and punish her lack of escape |
Levels 1-2 already favor Irelia thanks to Bladesurge minion resets that let her jump on you repeatedly. You have no shield and weak trading tools, so avoid standing near low-hp minions she can reset off. Play behind minions and only poke with Q from max range. Losing cs to safety is fine here. Track Flawless Duet: 16s at rank 1, 10s at rank 5 — dodge the converge and her all-in has no opener.

Start Doran's Shield + Health Potion and back for Oblivion Orb (≈800g) — cuts her sustain. Build Rod of Ages first, then Seraph's Embrace, with Sorcerer's Shoes.
