Read from Irelia's seat: which stage windows this plan plays for against Mordekaiser.
This is Irelia's own plan; across 665 pooled games the lane is leaning Irelia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is even — he has no dash and only E-poke, so you just farm with Q-resets off the wave and stay clear of his pull range. |
| Level 2 | Mordekaiser | At 2 his W (Indestructible) shield heals back your poke and his isolated Q out-trades you before your E is online — concede the window. |
| Level 3 | Mordekaiser | He out-trades your level 3 unless you land a clean E-stun first; miss it and his isolated Q plus shield-heal win the extended fight. |
| Levels 4-5 | Even / skill | Levels 4-5 are a genuine coinflip — your Bladesurge reset wins a short skirmish, but his W sustain wins anything that drags long. |
| Level 6 | Mordekaiser | His Realm of Death (R) drags you into a no-minion 1v1 with zero Bladesurge resets and steals your stats — his single best window. |
| First item | Mordekaiser | His first AP item plus isolated-Q damage tip the solo duel his way; don't take a W-shielded fight you can't reset out of. |
| Two+ items | Irelia | At 2+ items your full reset uptime and on-hit magic damage out-DPS the dashless juggernaut — outside his R cooldown the duel is yours. |
Level 1 is genuinely even — neither of us wants to commit, so I farm with Q off the wave and stay out of his E (Death's Grasp) pull range. Once he hits 2 he's the bully: his W (Indestructible) shields and heals back my poke, and his Q hits harder when he isolates me, so I can't just trade autos. My one window is my own E-stun at 3 into a Q-reset — land it ON the wave so a minion death refreshes Bladesurge, burst him, and disengage before his shield charges. Whiff the E and I lose the trade and the level.
